Description

The present invention comprises a video recording device compatible with a network, a portable terminal connectable to the network, and a server computer that performs a recording reservation service via the network, and controls the recording device by connecting to the recording reservation service from the portable terminal. It relates to technology .

  It is a common practice for a multi-user OS (operating system) to log in to a computer connected to a network simultaneously from a plurality of terminals. In this case, shared resources such as an input / output device (I / O) of a computer are used by a plurality of terminals while performing exclusive control. As a result, when viewed from each terminal, it is possible to provide a feeling of use as if each terminal is using the computer exclusively.

  In such an OS, for example, a home directory location is provided for each user. Normal users can only access this home directory. Therefore, even if a plurality of users share one computer, it is possible to perform processing on files and e-mails created by themselves without considering other users' files. As a result, you can use your computer as if it were your own.

  For this purpose, the terminal (and user) identification information is sent to the computer, such as inputting a user name and password from the terminal at the time of login, and the computer collates it with identification information stored in advance, and the terminal To allow or disallow connection.

  In this case, it is necessary to set user identification information on the computer side. Also, identification information is often stored in advance on the terminal side. When it cannot be memorize | stored in a terminal, the method of having a user input a user name and a password every time is taken.

  On the other hand, with the recent development of electronic technology and AV (Audio-Visual) technology, it has become common for computers to process video signals and audio signals such as television (hereinafter simply referred to as “TV”) signals. ing. Typically, a recording device which is composed of a computer provided with a TV tuner and a hard disk and can record a TV program on the hard disk is becoming widespread. When such a recording device is used at home, there are many users. In many cases, there are a plurality of TV sets connected to such a recording device. That is, it is expected that a plurality of users will perform their own operations using one recording device.

  Also, with the development of network technology, fusion of TV broadcasting and network is also progressing. In such an environment, the recording device can be controlled not only by using the operation panel or remote controller of the recording device but also from a terminal that can be connected to the network. In this case as well, a mechanism capable of controlling the recording device from a plurality of terminals is necessary.

  Therefore, the recording device as described above also needs the same function as a general multi-user OS.

  In addition, when controlling a recording device from a terminal via a network, a server computer can be provided that performs control of the recording device. In this case, it is conceivable that the terminal is connected to the server computer with authentication, and the server computer is connected to the recording device with authentication.

  As described above, a recording device that can be connected to a network, a server computer that is connected to the network, provides TV program information in response to a request from a terminal, and has a function of controlling the recording device, and a network via a public line There is also known a system for making a recording reservation from a mobile phone to a recording device via a server. Such a system is disclosed in Patent Document 1 described later.

FIG. 42 shows an outline of the system disclosed in Patent Document 1. Referring to FIG. 42, this system includes a mobile phone 902 that can be connected to the wireless network 105 via a public line, an electronic mail server 900 connected to the wireless network 105 and the network 104, and an electronic mail server via the network 104. And a recording device 904 that can be connected to 900. The recording device 904 has a remote controller 906 . A TV monitor 908 is connected to the recording device 904 .

In such a method of including a recording reservation command in the mail, the user of the mobile phone 902 transmits an e-mail in a format as shown in FIG. 43 to the e-mail server 900 to the recording device 904 . This e-mail is temporarily stored in the e-mail server 900. The recording device 904 periodically accesses its own mailbox on the email server 900 and reads this email. If the e-mail is a recording reservation, the recording device 904 executes a program recording reservation process in accordance with the reservation content described in the e-mail body.

In the system described in Patent Document 1, the recording device 904 includes a teletext receiving tuner, and transmits program information received by teletext to the mobile phone 902 by e-mail. The user of the mobile phone 902 makes a program reservation by looking at this information.

Since the cellular phone 902 is personal to the user, according to this system, the cellular phone 902 can be used as a personal remote controller for the recording device 904 . Since the mobile phone is connected to the e-mail server 900 via a wireless network, the mobile phone 902 can be operated in the living room where the recording device 904 is located. Even when the user is moving with the mobile phone 902, the recording device 904 can be operated. Therefore, all operations can be performed with the mobile phone 902 without directly operating the recording device 904 or using the remote controller 906 .

In addition to the electronic mail server 900, a server for providing program information to the mobile phone 902 may be provided. In this case, the server service is used by the mobile phone browser to control the recording device as follows. That is, first, the mobile phone 902 is used to connect to the server and apply for the service. The server creates authentication information such as a user-specific login URL (Uniform Resource Locator) for this application and transmits it to the mobile phone 902 . The mobile phone acquires this authentication information and uses the URL for subsequent server access. Thereby, the server can identify the user of the mobile phone 902 .

If the server service becomes available from the mobile phone in this way, it is necessary to link the recording device 904 and the server service next. For this purpose, connection management information of services that can be operated by the mobile phone 902 must be set in the recording device 904 . As the connection management information, for example, the server address of the e-mail server 900 and account information when the recording device 904 accesses the e-mail server 900 must be set.

  As a program guide service, there is a service that does not directly control program reservation for a recording device. For example, the server transmits a program guide with a specific code attached to each program to the mobile phone. This code is pre-determined so that it can be used when making a recording reservation for the recording device. The user silently displays the code displayed on the mobile phone and performs key input to the recording device that is the operated device.

  Although the recording reservation of the recording device can also be made by such a method, as a service, the individual program information is simply transmitted to the mobile phone together with auxiliary information (code) for reserving the recording. It is not a way to continually link services with mobile phones. Therefore, when the mobile phone is located away from the recording device, it is impossible to control the recording device via this service.

Japanese Patent Laid-Open No. 2001-136453

  To use server services with a mobile phone and control a recording device connected to the network, register the mobile phone identification information with the server, enable authentication, and configure the server associated with the mobile phone. It is necessary to configure authentication so that the recording device can access the service.

This procedure is cumbersome when using the service, and errors are likely to occur. Normally, when operating the recording device 904 , the remote controller 906 is used as an input means, and the screen of the TV monitor 908 is used as a display unit. Therefore, if the setting items to be registered in the recording device in association with the mobile phone service of the server 900 are diverse, the setting operation is difficult.

  For example, in the case of a recording reservation mail service using e-mail, a user can use a POP mail server name, an SMTP server name, an account name and a password for accessing a mailbox, a mail address name, and a reply mail address related to his mail account. Need to investigate. Further, the user needs to set a password for recording reservation. Of these, the user accurately registers the e-mail address and recording reservation password on the server side, and the POP mail server name, SMTP server name, account name, mailbox access password on the recording device side, It is necessary to register the e-mail address name, recording reservation password, and reply e-mail address correctly.

It is difficult to manage these pieces of information accurately unless there is a certain degree of knowledge about not only the recording equipment but also the network mechanism, and it is difficult for the user to investigate such information in the first place. Even if all the information is available, it is not easy to set it correctly in the recording device 904 . In particular, when inputting a password or the like, the screen is normally hidden, so it is difficult to check for input errors. Since there is a wide variety of information to be set, if there is an input error and recording reservation cannot be made, it is difficult to find out where the error was.

  Moreover, in the conventional recording reservation mail service disclosed in Patent Document 1, there is one recording reservation account that can be used by the user. Patent Document 1 does not disclose a technique for uniformly handling a plurality of recording devices. For example, when a recording device has only one tuner, it is desirable to appropriately allocate recording reservations to a plurality of recording devices in order to record programs of different channels at the same time. However, in Patent Document 1, such control cannot be performed. Recording equipment may be purchased, and how to control a plurality of recording equipment to perform recording reservation and recording is an important problem in actual use.

Furthermore, in the technique disclosed in Patent Document 1, when a program of another channel is recorded at the same time by a plurality of recording reservations for a certain recording device, the recording reservation cannot be performed if the number of tuners of the recording device is insufficient. There is. Even in such a case, it is desirable to make use of program reservation as much as possible so that the program can be recorded.

  Furthermore, when one or more recording devices are shared by a family, it is desirable to distinguish and appropriately process recording reservations by a plurality of users, but this is not possible with the technique described in Patent Document 1. . Therefore, the recording reservations made by a plurality of users are displayed and executed without being distinguished from each other, and the user cannot use the recording device with his / her own feeling as described above.

  Therefore, in the conventional system, even if an attempt is made to use a service for making a recording reservation via a network, setting for that purpose is difficult and it cannot be easily used by general users.

  Further, when such processing is performed via a network, it is desirable not to be adversely affected by malicious user actions.

  Further, the program information service provider server 102 issues a URL that allows only the applied mobile phone to log in as a reply mail, and notifies the user of the account number described above by the mail (see the account notification screen 120 in FIG. 12). ).

  The user 114 views the account number displayed on the mobile phone 112 (indicated by a line 142), and inputs the account information to the recording device 106 by using the remote controller 108 (indicated by a line 144). Assume that all account numbers are numbers in the present embodiment. Therefore, even when the key of the remote controller 108 is only a number, it can be input by the remote controller 108. Of course, if the non-numeric key can be easily input to the recording device 106, the account number does not need to be a number only. The recording device 106 is connected to the program information service provider server 102 via the network 104 and notifies the account number input by the user 114.

  In response to this notification, the program information service provider server 102 notifies the recording device 106 of information corresponding to the account number. The recording device 106 receives this information and sets it as service usage information. As a result, the recording device 106 can thereafter receive control information issued by the program information service provider server 102 by a remote control operation from the mobile phone 112.

  FIG. 3 shows a schematic operation of the system 100 when making a recording reservation of the recording device 106 from the mobile phone 112 using this service. Referring to FIG. 3, first, mobile phone 112 accesses the URL notified from program information service provider server 102 at the time of service subscription (160). On the other hand, the program information service provider server 102 edits the recommended information prepared in advance for each subscriber, creates an HTML document, and sends it back to the mobile phone 112 (162). As a result, the recommended program list screen 164 is displayed on the screen of the mobile phone 112. Of course, the screen shown in FIG. 3 is an example.

  The user can move to the program explanation screen 166 by following the link of the recommended program list screen 164. On this screen 166, a link for mail recording is provided. By clicking the link for mail recording, a recording reservation mail from the mobile phone 112 to the recording device 106 is transmitted to the mail server in the program information service provider server 102.

  When a predetermined event occurs, the recording device 106 accesses its own mailbox of the program information service provider server 102 periodically at a predetermined timing, for example (180), and checks whether an e-mail has arrived. . When an e-mail for recording reservation is received, the recording device 106 makes a recording reservation according to the contents. The recording device 106 further sends an e-mail addressed to the mobile phone 112 indicating that the recording reservation has been completed to the mail server of the program information service provider server 102.

  The mobile phone 112 that has received this e-mail displays it on the recording reservation completion screen 168. In this embodiment, the recording reservation completion screen 168 is provided with a link for listing other recording schedules, and when this is clicked, a recording reservation list screen 170 is displayed. A recording reservation list in the recording device 106 can be listed on the recording reservation list screen 170. The list format will be described later.

  The presence of the URL storage unit 196 allows the mobile phone 112 to select, store, and reuse the URL. That is, for example, a login-only URL sent by e-mail from the program information service provider server 102 is stored in the URL storage unit 196, and then the URL can be accessed when desired. Of course, the user name and password for login may be issued and the user may be prompted to input the user name and password every time. However, it is convenient for the user to use the dedicated URL as described above.

[Program information service provider server 102]
The program information service provider server 102 shown in FIGS. 1 to 3 broadly includes a service provider that enables browsing of an electronic program guide to an HTML browser of a mobile phone that can be connected to a network, and the server. It is a concept to do. Narrowly, the program information service provider server 102 refers to a server computer system for providing the above-described service.

  The program information service provider server 102 is a server computer (hereinafter simply referred to as “server”) on which software including a Web server and a mail server operates. A functional block configuration of the program information service provider server 102 is shown in FIG.

  Referring to FIG. 6, program information service provider server 102 includes a recording device management unit 244, a recording reservation database (DB) unit 246, a user account information storage unit 248, a user account management unit 250, and a program information management. Unit 242, program information storage unit 240, WWW (World Wide Web) WWW server 258, mail processing unit 252, mail server unit 254, and e-mail including recording reservation information processed by mail server unit 254 And a mail storage unit 256 including a mail box as a data storage device that stores an area for each mail account and provides an area for delivery to a recording device that is a target of recording reservation. The mail server unit 254 is connected to the recording device 106 via the network 104. The WWW server 258 is connected to the mobile phone 112 via the wireless network 105.

  FIG. 7 shows an outline of the account information 280 for each user stored in the user account information storage unit 248 of FIG. As shown in FIG. 7, the account information 280 includes an e-mail address of the mobile phone that performed the service subscription process, an e-mail account for sending an e-mail for making a recording reservation to the recording device, and a recording reservation e-mail. Recording mail read password for reading from the storage unit 256, recording POP mail server name, recording mail address name, SMTP server name for recording reservation, service name of this service, and e-mail for recording reservation Includes a recording reservation password to be included in the password, an account number issued to the mobile phone, individual identification information of the controlled device, and a login URL for the mobile phone.

  Upon receiving the application mail, the user account management unit 250 shown in FIG. 6 generates a recording device control account and an account information structure associated with the mobile mail address of the transmission source. The recording device control account is used to secure a storage area for transmitting authentication information and control commands used for communication with the recording device. The structure of the account information structure will be described later, but is a collection of these pieces of information. The account information structure is associated with the account number and can be referred to from the account number. In the present embodiment, the program information service provider server 102 transmits the account number to the mobile phone that has transmitted the application mail. The mobile phone displays this, and the user views it and inputs it to the recording device. The recording device that has received the input of the account device accesses the server 102 based on the account number. The server 102 authenticates the account number, and transmits the post-authentication account information structure to be passed to the recording device to the recording device.

  In this way, account information is set in the recording device. Accordingly, communication between the recording device and the server 102 can be established thereafter, and control by the server 102 can be accepted. Therefore, the recording device can be controlled by the mobile phone via the service of the server 102.

  In the example shown in FIG. 7, for example, the e-mail address of the mobile phone is papa @ isp1, the e-mail account for recording reservation is a12345, and so on.

  As a specific example of the recording device control account, a recording reservation mail account that is different for each mobile mail address is generated in the mail server unit 254 of FIG. The account information structure stores the mail account information in the user account information storage unit 248 of FIG.

  That is, when there is an application for service subscription, the recorded mail account name, recorded mail password, recorded mail POP server name, recorded mail transmission SMTP server name, and recorded mail address are sent to the mail server unit 254 shown in FIG. Set up a new email account so that you can send and receive scheduled recording emails.

  In the e-mail recording reservation method, a password for recording reservation is determined on the server side and the recording device side, and if the recording reservation password included in the e-mail recording command matches this, the e-mail is recorded as a regular recording command. The method of authenticating as is generally used. In this embodiment, it is assumed that the recording reservation password is generated as a random number of about 8 digits so as not to overlap with the previously issued portion. Then, it is included in the account structure as shown in FIG. 7 and stored in the user account information storage unit 248 of FIG. The account information is information that needs to be shared between the server and the recording device in the recording reservation by e-mail described later.

In addition, in the present embodiment, the account information structure in FIG. 7 includes a character string for identifying this service as a service name. Further, the account information structure may include a URL address to an image for identifying the service of the server. In the example of FIG. 7 , the character string “TV navigation” represents the service name.

  In addition, as will be described later, a URL for mobile phone login from the mobile phone used for the application is also stored. If the URL is accessed from the mobile phone, information associated with the account is provided to the mobile phone.

  Such complicated and diverse account information must be shared between the server and the recording device in order to realize the recording reservation control. However, if this account information is displayed on the mobile phone and the user is allowed to set the recording device correctly, the psychological burden on the user increases. Also, if the input operation by the remote controller of the recording device is assumed, there is a high possibility of inducing an error, and it is difficult to detect it even if it is wrong.

  Therefore, in this embodiment, an account number for identifying account information is generated by the server 102, and the account information is represented by the account number. By displaying the account number on the mobile phone and inputting it to the recording device, the recording device acquires account information from the server based on the account number.

  Preferably, a multi-digit number, for example, a 16-digit number is generated as the account number. In the present embodiment, the number string of account numbers consists of three areas. That is, the upper 2 digits of the number are the service provider identification number of the server, the middle 12 digits are a random number, and the lower 2 digits are the total value (checksum) of the upper 14 digits.

  The service provider identification number is a number for distinguishing the maximum number of servers as 100. The service provider identification number is assigned to each service provider by a unified organization. The recording device 106 has a built-in table for converting the service provider number into the DNS (Domain Name Service) name of the service provider server.

  The following effects are obtained by the checksum. For example, it is assumed that the service provider identification number of the server is 32 and the generated random number is 14093822145. At this time, the checksum is 47. As a result, “3214098232314547” is the account number. If the recording device that has received this account number adds the upper 14 digits and compares it with the lower 2 digits of the checksum, it can be easily confirmed whether or not it has been entered without error. The checksum may be generated by any algorithm as long as it is appropriate as a checksum, such as message digest MD5.

  In the present embodiment, the following measures are taken with respect to the middle 12-digit portion so that server account information cannot be obtained illegally with a random account number. That is, the user account management unit 250 stores numbers issued in the past, and generates 12 digits from the third digit to the fourteenth digit by using a random number that does not overlap with this number. There are 1 trillion possible 12-digit accounts. Even if 1 million accounts are generated with random numbers, the probability that the estimated account numbers coincide by chance is 1 / 1,000,000. Therefore, this account number is equivalent to authentication data for identifying an individual such as a user name and a password. That is, there is an advantage that account information cannot be acquired even if a third party randomly generates an account number and accesses the user account management unit 250.

An example of an HTML document prepared for service application by the program information service provider server 102 shown in FIG. 6 is shown in FIG. Referring to FIG. 8, the HTML document includes “mailto” which is a tag for starting an electronic mail program. This document expects that an application from a user will be made by e-mail transmission from this HTML document.

  “master @ EPGservice”, which is the e-mail address of the service manager of the program information service provider server 102, is set as a parameter of the mailto tag, and further, an application for the service is made in the body (the part below “body =”) It includes a character “join” indicating that it is an e-mail and a character string “9734567123” which is a one-time character string generated based on a 32-bit integer random number. This one-time character string is generated literally once and stored by the program information service provider server 102 for a certain period.

  When the one-time character string “9734567123” is included in the body designation part of the mailto tag, and the user selects the “apply” link linked to this tag, the mail transmission / reception unit of the mobile phone A subscription application mobile mail in which “join 973567123” including a one-time character string in the mail body is transmitted to the administrator of the program information service provider server 102. The mail sender is the address of the mobile phone mail.

  Whether or not the one-time character string stored in the service application mail received by the program information service provider server 102 is included in the body of the service application mail in this way is included. judge. Thereby, it can be determined whether or not the service application mail is authentic, and when the application mail is transmitted to the program information service provider server 102 in a malicious manner, it can be determined as illegal and can be eliminated.

  When the application mail determined to be authentic is received, the program information service provider server 102 creates an account for recording reservation based on the e-mail address of the mobile phone, as will be described later, and also the account for using the service. A dedicated URL is created and sent back to the sender of the application email by e-mail. An example of the format of the reply mail is shown in FIG. In the example shown in FIG. 9, “http: // EPGservice / login” is information that specifies a program for login processing, and the portion after “?” Is information that is passed to the program. In the example shown in FIG. 9, a user ID (account information) is passed to the program. Subsequent processing is controlled by this account information.

  The program information service provider server 102 shown in FIG. 6 is realized by computer hardware and software operating on the computer hardware. The hardware configuration of the program information service provider server 102 is shown in FIG.

  Referring to FIG. 10, program information service provider server 102 has a standard configuration as a server that provides Internet services. That is, the program information service provider server 102 includes a CPU 302, a memory 304, a network I / O 306, and a storage I / O 308, all of which are connected to the path 300 with the bus 300 as a center. Program information service provider server 102 further includes a hard disk 310 connected to @ 300 via storage I / O 308.

  Since the operating principle of the program information service provider server 102 is the same as that of an ordinary computer, details thereof will not be repeated here.

  Each function of the program information service provider server 102 shown in FIG. 6 is realized by hardware shown in FIG. 10 and software executed thereon. FIG. 11 shows a processing flow of a program executed by the program information service provider server 102 when access to the service entrance URL prepared in the program information service provider server 102 is from a mobile phone.

  Referring to FIG. 11, when the service entrance URL is accessed, program information service provider server 102 creates a one-time character string using a 32-bit random number (step 330). Subsequently, an HTML text (see FIG. 8) for the application screen including this one-time character string is created (step 332). Finally, the HTML text is returned to the mobile phone that was accessed first (step 334), and the process is terminated.

  A service application screen is displayed by processing the HTML text on the mobile phone. By clicking the link associated with the “Apply” text on this application screen, the email containing the above one-time character string in the text will be sent to the specified address, and the application for the service has been completed. It will be. FIG. 9 shows an electronic mail returned from the program information service provider server 102 to the mobile phone in response to the subscription application.

  When the user requests to display his / her account number, the program information service provider server 102 returns an HTML text including the user's account number to the user's mobile phone. The display on the mobile phone in this case is shown in FIG.

  Referring to FIG. 12, at this time, account number 340 is displayed on screen 120 of mobile phone 112. By inputting this account number to the recording device 106, the setting for using the recording reservation service using the program information service provider server 102 is automatically performed on the recording device 106 as described above.

  FIG. 13 shows a program executed in the program information service provider server 102 to create HTML text including a dedicated bookmark transmitted from the program information service provider server 102 to the mobile phone 112 when the service shown in FIG. 9 is subscribed. It is a flowchart.

  Referring to FIG. 13, first, in step 350, the mail address “master @ EPGservice”, which is the e-mail address of the service manager of the mail server attached to the program information service provider server 102, is accessed, and one e-mail is sent. read out. In step 352, it is determined whether or not a recently issued one-time character string is included in the body of the e-mail. If a one-time character string is included, control proceeds to step 354. Otherwise, return to step 350.

  In step 354, account information for the user is created in the user account information storage unit 248 shown in FIG. At this time, an account number for uniquely identifying the account is generated.

  In step 356, a mail account for the user is created in a mail server attached to the program information service provider server 102. Further, in step 358, a confirmation e-mail including the unique mobile phone user login URL assigned to this account by the program information service provider server 102 is created (step 358), and transmitted to the address of the mobile phone that has applied for the subscription (step 358). Step 360). When the transmission is completed, control returns to step 350 and the above processing is repeated.

  The mobile phone user login URL is included in the account information structure of FIG. In this example, the mobile phone user login URL includes an account number as an argument.

  When the user clicks the link to the user login URL, the browser is activated, and a service screen unique to the user of the cellular phone who applied for is displayed. A screen (FIG. 12) for notifying the account number is provided. Alternatively, the above account number may be simply written and an e-mail notifying the application confirmation may be used.

  FIG. 14 is a flowchart of a program executed in the program information service provider server 102 when the user login URL is accessed from a mobile phone. First, in step 380, the user account number included in the user login URL is extracted. In step 382, an HTML text for displaying the account number is created. In step 384, the HTML text is returned to the mobile phone. As a result, an account number message as shown in FIG. 12 is displayed on the user's mobile phone. The user views this information and inputs an account number to the recording device 106. As a result, the recording device 106 creates an account information acquisition request based on this account number and sends it to the program information service provider server 102. This account information acquisition request includes the account number input by the user and the individual identification information of the recording device 106.

  FIG. 15 is a flowchart of a program executed by the program information service provider server 102 in response to this account information acquisition request. Referring to FIG. 15, first, in step 400, an account information acquisition request is received. In step 402, the user account management unit 250 is inquired to determine whether the account number included in the received account information acquisition request has already been issued. If it has been issued, control proceeds to step 404. Otherwise, exit this program.

In step 404, the account information corresponding to the account number included in the regular account information acquisition request is read from the user account information storage unit 248 (see FIG. 6) and returned to the recording device 106 that issued the request. The transmitted account information includes a mobile mail address, a recording mail address, a recording mail password, a recording POP mail server name, a recording mail SMTP server name, a service name, a recording reservation password, and an account number. These are set and stored in the account information storage unit 470 through the account management unit 464 shown in FIG. The service name is an identification character string for improving readability. Further, since the account information acquisition request from the recording device 106 includes the individual identification information of the recording device 106, the individual identification information is added to the account information (step 406), and the process is terminated.
Since an account can be set for a plurality of recording devices, a plurality of pieces of individual identification information may be added to one account information structure. That is, for example, information on which manufacturing company, what model serial number, what recording device, and how many recording devices there are, is recorded on the server 102 as a user having an email address of papa @ isp1. become.

  Furthermore, the account information can be generated with an expiration date, and the account information can be invalidated if there is no account information acquisition request from the recording device 106 within a certain period after the account information is generated. Delete account information. As a result, it is possible to protect a finite resource called account number against malicious attacks that only cause account creation and cause unnecessary account creation in a way that is not used by a service receiving apparatus.

  FIG. 16 shows a program for transmitting recommended information for the user from the program information service provider server 102 when the user logs in to the service using a dedicated URL. This dedicated URL includes the user's account number. In step 420, the user account number is extracted from the login URL. Subsequently, in step 422, it is determined whether or not this account number has been issued. If the account has been issued, control proceeds to step 424. Otherwise, exit this program.

  In step 424, the program information service provider server 102 creates recommended information based on the account number. This recommended information includes a program name and an e-mail address linked to the program name for making a recording reservation for the program. In step 426, the recommended information is returned, and the process is terminated.

  The above is the configuration of the program information service provider server 102 and the configuration of the program that implements each functional unit of the program information service provider server 102.

The video encoder / decoder unit 494 corresponds to the video encoder / decoder unit 444 of FIG. The tuner unit 496 corresponds to the broadcast receiving unit 442 in FIG. Further, the memory 484 and the hard disk 498 correspond to a recorded video data storage unit 446, a program information service server DB 458, a recording reservation DB 454, and an account information storage unit 470.

  The recording management unit 450, the program information service connection unit 460, the program reservation information management unit 456, the account management unit 464, and the like illustrated in FIG. 17 are realized by programs executed by the CPU 482 and the CPU 482 illustrated in FIG.

  FIG. 19 shows the contents of the program information service server DB 458 of FIG. Referring to FIG. 19, program information service server DB 458 stores the server name of the program information service in combination with a number (service number) assigned to the program information service. In the present embodiment, the service number has two digits. The upper two digits of each account number match the service number of the program information service used by the account. Therefore, by searching the program information service server DB 458 using the upper two digits of the account number, the program information service server used by the account number can be specified.

  FIG. 20 is a flowchart of a program executed when the recording device 106 receives an account number input by the user, automatically accesses the program information service server corresponding to the account number, and acquires account information. is there. Referring to FIG. 20, this program starts at step 510, and at step 510, it is determined whether or not the remote control operation is received and the account input screen is displayed. This determination is repeated until the account input screen is displayed. That is, in the TV monitor display of the recording device, the operation of the remote controller 108 is awaited, and when the user selects the account registration menu by operating the remote controller 108, the account management unit 464 of FIG. The current account registration status is displayed on the TV monitor 110 through the display management unit 448. The input field is focused and waiting for input. Control continues to step 512. An example of the screen at this time is shown in FIG.

  Referring to FIG. 21, on account setting screen 122 of TV monitor 110, three account input units 124A, 124B and 124C are displayed in the present embodiment. Therefore, in the present embodiment, a maximum of three accounts can be set in one recording device 106. As shown in FIG. 21, check boxes 530, 532, and 534 are displayed at the left ends of the account input sections 124A, 124B, and 124C. For accounts that have been set, the account valid / invalid field is set to valid as described later, and in this case, this check box is checked. You can also switch between valid and invalid. In the example shown in FIG. 21, the first account has been set. At the time of input, the remote controller is used to focus on any of the account input units 124A, 124B, and 124C (one field is set as an input target).

  The account input screen has a plurality of input fields, and the user uses the up and down keys of the recording device remote control to move the focus so that one can be selected and displayed on the television monitor.

  In FIG. 21, a registered mobile mail address is displayed in the already input field. If you focus on an account that has already been set and enter the account number, it will be overwritten.

  As described above, when the recording device 106 receives the account number from the Ir transmission / reception unit (remote control management unit 466 in FIG. 17), the recording device 106 checks the checksum and confirms that the number is definitely input to the recording device. If there is an error, it is displayed on the TV monitor 110 to prompt re-input. Since the account number is about 16 digits, it can be reliably transmitted even with a low-speed non-procedural communication method such as a remote control format for home appliances.

Referring again to FIG. 20, in step 512, the account that is in focus is waiting for input. When the input something is, it determines whether the account number input is completed in step 514. If completed, control proceeds to step 516. Otherwise, control returns to step 512.

  Next, the recording device 106 requests the server 102 to provide account information while revealing its identity. The server 102 identifies the feature of the recording device 106 by the following procedure.

  That is, in step 516, the program information service server name is searched from the upper two digits of the input account number with reference to the program information service server DB 458 shown in FIG. In the subsequent step 518, connection is made to the recording device management unit 244 (see FIG. 6) of the searched program information service server, and the account number input in step 512 and the individual identification information of the recording device 106 are transmitted.

  In subsequent step 520, in response to the account number transmitted in step 518, it is determined whether or not the account information has been returned from the server without error. If the account information is returned without error, control proceeds to step 524. Otherwise control proceeds to step 522.

  In step 524, the account information acquired in step 520 is stored in the account information storage unit 470 shown in FIG. Further, the above-described account validity / invalidity field is set validly, and the process is terminated.

  On the other hand, if an error is returned from the server for the transmission of the account number, an error message corresponding to the error is displayed in step 522 and the user is prompted to input the account number again. Control returns to step 512.

  By executing the above processing, the input of a new account number and the processing for acquiring account information corresponding to the account number from the program information service server are completed. The model name and serial number included in the account information are information written in a nonvolatile memory such as a hard disk inside the recording device 106 at the time of manufacturing. Since this individual identification information is additionally stored in the account information structure of the server 102 in FIG. 7, the server 102 can identify the individual recording device 106 for which the account is set. This communication may be performed safely using encrypted communication such as SSL (Secure Socket Layer) without risk of eavesdropping or tampering.

  The recording device 106 may be up-to-date by acquiring account information from the recording device management unit when the power is turned on or periodically.

  As described above, in the system according to the present embodiment, when the user inputs the account number displayed on the mobile phone to the recording device 106, the recording device 106 automatically accesses the program information server thereafter and identifies itself. Account information for proper setting can be acquired. There is no need for users to investigate and prepare a wide range of information in advance. In addition, since the account information is automatically set, the user can quickly set the correct operation without knowing the details of the account information.

In this procedure, the individual identification information of the recording device is sent to the recording device management unit 244 of the server 102 in addition to the account number. Therefore, the recording device management unit 244 has an advantage that it can perform recording control using the model-dependent function of the recording device 106 in the subsequent control. For example, if it is possible to select image quality, sound quality, recording destination (hard disk or DVD), etc., in the product called MAKER1-HDD9000, the recording device management unit 244 of the server 102 displays image quality, sound quality on the recording reservation screen of the mobile phone browser. The user can select a recording destination option and send it to the mail recording reservation command as an extended function. For example, if the recording reservation command is “Open 264575 TV SC503 1300 1330 1031 “VS A1 When “SH” ”, the video recording reservation command may be added with an option to specify that the video image quality is SP (high image quality mode), the audio is D1 sound quality, and the recording destination is the hard disk (H).

  In addition, since the recording device management unit 244 includes the manufacturing number, the recording device management unit 244 can recognize not only the product type but also the individual recording device 106 itself. Therefore, even if an account is set for the same recording device from each of a plurality of mobile phones, it can be distinguished on the server side that the recording reservation is for the same recording device.

  In FIG. 22, the recording device 106 checks the presence / absence of a program recording reservation made by e-mail from the user, and if there is a recording reservation by e-mail, executes a process for setting the recording reservation according to the contents. FIG.

  Referring to FIG. 22, first, in step 550, the POP server of program information service provider server 102 is accessed at the scheduled time to determine whether or not the connection is successful. If the connection is successful, control proceeds to step 552. Otherwise, control returns to step 550.

  In step 552, an initial value of 0 is set to a repetition control variable i that controls repetition of the following processing. Hereinafter, iterative processing using this iterative control variable i will be described.

  In step 554, it is determined whether or not the repetition variable i matches the number of account numbers set in the recording device 106 (this is “N”. In this embodiment, N = 3). Determine. If they match, control returns to step 550. If not, control proceeds to step 556.

  In step 556, the i-th account is taken out, and in step 558, it is determined whether or not the account is valid. If valid, control proceeds to step 560. Otherwise, control returns to step 554.

  In step 560, the e-mail is read from the mailbox of the i-th account. In the following step 562, it is determined whether the recording reservation password included in the read e-mail matches the recording reservation password of the account information stored in the recording device 106, and whether the recording condition is satisfied. Is done. If the determination result is YES, control proceeds to step 564, otherwise control proceeds to step 568.

  In the determination of step 562, the mail recording command is described in the first line of the mail text, starts with “Open”, the recording reservation password matches, the recording reservation time does not overlap with other reservations, and the channel Are not overlapped, and whether or not the recording condition such as the remaining amount of the hard disk being sufficient for recording or the reservation for the same program is satisfied is determined.

  The recording reservation password is created with a random number for each user account. Therefore, it can be regarded that the recording reservation passwords do not coincide with each other if the accounts are different. Therefore, when the recording reservation passwords match, the account number and the mobile mail address are associated with the recording reservation data.

  In step 564, the contents of the recording reservation described in the read electronic mail are additionally registered in the recording reservation DB 454 shown in FIG. Further, the read electronic mail is deleted from the mail server.

  In the following step 566, an e-mail indicating that the recording reservation is successful is issued to the e-mail address registered for the account. Thereafter, control proceeds to step 570.

  On the other hand, if the determination result in step 562 is NO, the control proceeds to step 568. In step 568, the read electronic mail is marked as read. Furthermore, an e-mail that cannot be reserved for recording is sent to the e-mail address registered for this account. Thereafter, control proceeds to step 570.

  In step 570, 1 is added to the repetition variable i. Thereafter, the control returns to step 554.

  By repeating the above process until the determination result in step 554 becomes YES, the process for checking whether there is a recording reservation for all the registered accounts and recording reservations at a predetermined time is completed.

FIG. 23 shows the structure of the recording reservation DB 454 shown in FIG. Referring to FIG. 23, the recording reservation DB 454 stores recording reservation records 590 and 592 for each account and each recording reservation. In this embodiment, each record includes an account number, a mobile mail address, information (time and channel) indicating the contents of recording reservation, and a flag indicating whether recording has been completed.

  As described above, in the first embodiment, account information associated with a mobile phone can be easily created in the recording device 106, and the mobile phone, service, and recording device are associated with each other. Therefore, the user interface of the recording device can be improved based on that. That is, in the system according to the present embodiment, account-specific recording data can be displayed. In the following description, it is assumed that two mobile phone accounts are set for one recording device and recording reservations are made by two users. When recording reservations of users with different hobbies and preferences are mixed, the operability may be reduced. However, in this embodiment, the mobile phone mail address is used as identification information, and the reservation information is classified and displayed.

  25 and 26 are recording data display lists displayed on the TV monitor 110 by the recording device 106. FIG. In FIG. 25, a recording list associated with papa @ isp1 is displayed. When the focus is moved with the up and down keys of the remote control and the enter key is pressed, the selected data is displayed on the television monitor. When the right key is pressed, a list of recordings associated with mama @ isp1 is displayed as shown in FIG.

  All of them are sorted by account to improve visibility, and those reserved for recording by another person are sorted and displayed individually. Since recording reservations can be managed for each account in this way, it is easy to install a function that can erase recorded data for each account at once.

  FIG. 24 is a flowchart of a program executed by the recording device 106 when the user requests the recording device 106 to display a recorded list. Referring to FIG. 24, first, in step 600, all account information is extracted from account information storage unit 470 via account management unit 464 shown in FIG. 17, and all mobile mail addresses used are read. Then, the maximum number of all these mobile mail addresses is set in the variable M.

  Subsequently, in step 602, the mobile mail address used for the recording reservation is stored in the array mailadr [M] on the memory.

  In step 604, an initial value of 0 is assigned to the iteration control variable J for subsequent iteration processing. Hereinafter, steps 606 to 610 are repeated processes.

  In step 606, a determination is made as to whether the value of variable J is less than variable M. If the determination result is YES, control proceeds to step 608. Otherwise, this process is terminated.

  In step 608, the record management unit 464 shown in FIG. 17 extracts a recorded record whose mobile phone mail address matches mailadr [J].

  In step 610, a recorded list is created based on the recorded records extracted in step 608 and displayed together with the mobile phone mail address mailadr [J]. Further, 1 is added to the value of variable J, and the process returns to step 606. At this time, the recording time associated with the recording reservation, the channel, and the thumbnail image extracted from the recording data are also displayed. This is shown in FIG. 25 and FIG.

  By repeating the above processing until the determination in step 606 is NO, a recorded list can be displayed for each mobile phone mail address.

  In addition, the recording reservation list can be easily created and displayed by making the data taken out in step 608 of the above-described processing not recorded but not recorded. Furthermore, by setting the value of the variable J to any value within the range of the number of mobile phone mail addresses, it is possible to display a list of recording reservations or the like by an account of a specific mobile phone mail address.

  25 and 26 show examples of recording reservation list display. Referring to FIG. 25, on this list display screen 640, a list of recording reservations by mobile phone mail addresses “papa @ isp1” and “mama @ isp1” is displayed. However, in this example, the recording reservation list of “papa @ isp1” is selected by a tab 642, and the recording reservation list of “mama @ isp1” is selected by a tab 644.

  The list display screen 640 displays a pair of arrow buttons 646 and 648 in the left-right direction, and the tab display can be switched by pressing these buttons. Similarly, up and down arrow buttons 650 and 652 are displayed, and when there are a large number of recording reservations displayed in a list, the display can be scrolled by operating these buttons.

-Operation-
The system 100 whose configuration has been described above operates as follows. First, a procedure when the user subscribes to the service of the program information service provider server 102 and the operation of each unit will be described.

FIG. 27 shows a signal diagram communicated between the program information service provider server 102, the mobile phone 112, and the recording device 106 in this case. Referring to FIG. 27, first, the user accesses the service entrance screen of program information service provider server 102 using cellular phone 112 (670). Program information service provider server 102 processes this access, to create a one-time character string (672), to send the HTML text of the screen application services including the one-time string to the mobile phone 112 (674). An example of the service application screen is shown in FIG.

  As shown in FIG. 28, the service application screen 700 of the mobile phone 112 includes a link 702 to the management e-mail address of the program information service provider server 102.

  Referring to FIG. 27 again, when the user of the mobile phone 112 clicks the link 702 on the service application screen 700, the application mail including the above-mentioned one-time character string is added to the management mail address of the program information service provider server 102. Is transmitted (676). FIG. 29 shows a text example of the transmitted mail.

  As shown in FIG. 29, the text portion of the application mail 710 includes a character string 712 composed of “join” indicating that it is an application mail and a one-time character string.

  Referring to FIG. 27 again, when receiving the application mail, the program information service provider server 102 determines whether or not the recently created one-time character string is included in the text, and if it is included, the account Information is created (678), and an account number notification screen is transmitted to the mobile phone 112 (680). The user visually checks the account number displayed on the mobile phone 112 and inputs it on the account setting screen of the recording device 106 (682).

  When the account number is set, the recording device 106 selects the program information service provider server based on the upper two digits, and notifies the program information service provider server 102 of the account information and its own individual identification information (684). ). The program information service provider server 102 determines whether there is account information corresponding to the account number notified from the recording device 106 (686), and if there is, returns the account information to the recording device 106 (688). The program information service provider server 102 also writes the individual identification information notified from the recording device 106 in the account information.

The recording device 106 that has received the account information sets each item of the account information structure necessary for connection to the program information service provider server 102 based on the account information (690) .

  This completes the application process for the service provided by the program information service provider server 102 by the user.

  30 and 31 show examples of account information structures stored in the recording device 106. FIG. The account information structure 730 shown in FIG. 30 and the account information structure 732 shown in FIG. 31 have the same structure. The account information structure 730 corresponds to the mobile mail address “mama @ isp1”, and the account information structure 732 corresponds to the mobile mail address “papa @ isp1”.

It is assumed that the mobile phone user stores the displayed mobile phone login URL in the URL storage unit 196 of the mobile phone 112 shown in FIG. When the recording device management unit 244 of the server 102 receives access to this URL, the recording device management unit 244 searches the user account management unit 250 to check whether an account exists. If it exists, a program information page accessible by an HTML browser is displayed for the mobile phone user as shown in FIG. Other users who do not know the mobile phone login URL cannot access this URL and are safe.

  When a specific user browses the program information display with a browser and selects a link called [Mail recording], this request is transmitted from the mobile phone to the recording device management unit of the server. A recording reservation mail is transmitted to a predetermined recording mail address according to the user. This is the same as starting a specific server function from a link of a web page using CGI (Common Gateway Interface) or the like, and is a normally performed process. Therefore, the details are omitted.

  In this system, program recommendation information can be sent from the server 102 to the mobile phone mail address, and recording reservations can be made to the recording device by simple operations.

  The server has already acquired the user's mobile mail address. Therefore, a program recommendation mail can be sent to the user. In that case, if the mobile phone user login URL is included in the e-mail, an e-mail such as the screen 164 in FIG. 3 is obtained. The user accesses the server 102 by selecting the corresponding URL link in the mail text. The server 102 authenticates the user by the user account management unit, and can display the recommended program information on the HTML browser of the mobile phone as shown in FIG. If the user selects a link [mail recording], a recording reservation control request for the corresponding program is transmitted to the recording device management unit 244 of the server 102. The server 102 can transmit a reservation mail from the recording device management unit 244 to a predetermined recording mail address according to the user.

A specific example of the operation will be shown. The mobile phone browser accesses the program introduction page and displays the screen 164 of FIG. If the user clicks the program link and clicks the recorded email reservation link [mail recording], the mobile phone browser issues a recording reservation email issuance request to the server 102, and the server 102 stores the recorded email address registered in advance. The recording reservation mail 180 is issued and stored in the mail storage unit 256.

  The operation principle of the recording reservation by the recording reservation mail used between the server 102 and the recording device 106 will be described. In the first line of the text of the scheduled recording mail issued by the server 102, for example, “Open 264575 TV SC503 1300 1330 1023 <New line> News show for dad” is described, as in FIG. ing.

  If the first argument is Open and the recording reservation password “264575” of the second argument matches the recording reservation password registered in the recording device 106 in advance, the received mail is authenticated, and the third argument “TV” ”Tuning to the channel (broadcasting station code starting with SC) described in the fourth argument by command. Further, recording is performed from the time of the fifth argument to the time of the seventh argument. The next line is the program name string.

The recording device reads the mail as follows. The recording device 106 in FIG. 3 periodically reads out mail from the mail account of the specific server 102. If a recording command is described in the read mail sentence, the recording device 106 tunes a specific channel for a specified time and performs recording from the time according to the recording command.

  In such a recording reservation by e-mail, if the channel, broadcasting time, and time are known, the recording reservation can be made by making a text written “Open 264575 TV SC503 1300 1330 1023” from a mobile phone and sending it by e-mail. Convenience is great because it is possible.

  In the recording reservation mail method as described above, the POP protocol is used for reading mail from the mail server. POP is a mail protocol that is also used as a standard in personal computers. The recording device 106 acquires the mail server address, mail account, and password from the account information, connects to the mail server section of the server, and reads the mail. If there is an email containing a recording reservation password that matches the recording reservation password recorded in the account information in advance, the recording reservation is attempted. If the recording reservation is successful, the mail is marked as read on the mail server.

  Next, the recording device 106 reads mail from the recording mail address at regular intervals. When multiple accounts are set in the recording device, the mail is sequentially read out to the server for each account.

  The recording device 106 includes a timer unit 462 as shown in FIG. When a predetermined time is reached by the timer unit 462, the account information storage unit 470 managed by the account management unit 464 is accessed, and one is sequentially extracted from the plurality of account information.

  The predetermined time is, for example, every other minute or three times a day at 11:40, 15:30, 18:30, and the like. This value can be changed by the user of the recording device.

The timer start time can also be set as follows for server load balancing. Timer time recording device 106 holds the settings in the recording equipment management unit 244 of the service side (6), so as to obtain at POP connection may be implemented so as to be changed from time to time the service side. As a result, there is an advantage that the load of the program information service provider server 102 can be distributed and the program information service provider server 102 can be activated at a desired time for each user.

  The recording device 106 reads mail from the server 102 as follows. The recording management unit 450 of the recording device 106 shown in FIG. 17 extracts account information from the account management unit 464, and if there are multiple accounts, the server POP mail stored in the account information through the network I / F unit 452 for each account. Connect to the server and read the email using the recording email account and recording email password.

  If the mail reading connection to the server fails, the connection may be repeated a plurality of times again after a certain time.

Even if the same account is set for a plurality of recording devices, the POP server cannot be logged in simultaneously with the same mail account due to the nature of the protocol, and is exclusively controlled. Therefore, it is possible to read the same mail account from a plurality of recording devices. As a result, a plurality of recording devices can be controlled with the same account, and the recording reservation is processed so that the reservation is successful with any one recording device. There are advantages such as efficient use of the hard disk as a whole recording device and simultaneous recording of programs of different channels. Details of this will be described later.

  If the timer activation time can be set, a time difference of about 1 minute is provided for the activation times of the plurality of recording devices 106. By connecting to the server with a time difference, the recording device that is started by the timer first can preferentially make a recording reservation.

  When recording reservation fails, the following processing is performed. By this processing, it is possible to realize a control in which a plurality of recording devices read a recording reservation mail from the same mail account, and record with a recording device that has been acquired first and has been successfully reserved. That is, processing distribution to a plurality of recording devices is realized.

  Referring to FIG. 17, when the recording management unit 450 cannot make a recording reservation such as when there is another reservation at the recording reservation time, or when the remaining amount of the storage medium is insufficient for the recording, the recording reservation including error information is performed. A reply mail is sent to the recording SMTP server in the account information. At this time, the mail subject includes “Subject: [Reservation Failure] News Show for Dad” and the program name and status.

  For the corresponding mail, individual mail specifying information on the mail server side of mail for each account (unique UIDL assigned to individual mail text on the mail server side in the POP protocol) in the account information storage unit 470 through the account management unit 464. Number) as read, but not deleted from the mail server.

  When a plurality of recording devices 106 access the mail server, the POP protocol exclusively controls connection to the server. Therefore, the recording reservation mail is sequentially read by a plurality of recording devices by the control as described above. Only mail that does not succeed in recording reservations is left on the mail server. Therefore, a recording reservation can be made when the next recording device reads the mail.

  Note that emails that fail to be scheduled for recording on all recording devices remain in the mail server. However, if the broadcast date of the program to be reserved has passed, control such as deletion from the mail server will add the email to the mail server. The rest will not continue.

  The server 102 may be notified of success or failure of the recording reservation. Accordingly, the server 102 can grasp which recording device is reserved even if there are a plurality of recording devices. Instead of the mail, the server may be connected to the recording device management unit 244 (FIG. 6) of the server using the HTTPS protocol, and the state may be safely notified to the server. This information is stored in the recording reservation DB unit 246 (FIG. 6).

  Since the connection to the server 102 is performed after authentication using an account number, a third party cannot notify information illegally.

At this time, the individual identification information of the recording device may be added to the mail for notification. In this case, the server can recognize which recording device has successfully recorded. Thus the server, such as when you click on the link "recording reservation of other users" in FIG. 33, on the basis of the individual identification information, intensive grasp the recording reservation situation in general from a plurality of mobile phone recording equipment unit There is an advantage that the recording reservation status can be notified to an individual mobile phone. For example, recording reservations by accounts from two mobile phones are centrally managed by the server, so that the user of one account can check the recording reservation status of the user of the other account on the mobile phone.

  The server 102 may create a recorded or successful recording reservation list based on the information and present it to the user on the program information page of the mobile phone program information providing page. Therefore, when the user makes a recording reservation from the mobile phone, the server 102 can determine that recording cannot be performed if an attempt is made to reserve a program that has already been reserved for recording, and can display an error.

The transmission of reservation information from the recording device 106 to the server 102 may include reservation information by deleting a reservation or operating a remote controller. In this case, the server side can completely grasp the reservation status of the recording device. If the server 102 is only to be completely grasp the reservation status of the recording device, the channel from the mobile phone there is an advantage, such as can stage Dee error display was trying to put the reservation that overlaps the recording time to the difference.

The recording reservation is processed as follows. When the timer unit 462 shown in FIG. 17 reaches the scheduled recording time, the recording management unit 450 is activated, the channel of the broadcast receiving unit 442 is controlled, and the video encoder / decoder unit 444 is controlled to create recorded video data. The recording manager 450 turns on the recorded flag of the reservation information associated with the account information in the recording reservation DB 454 .

Furthermore, in this embodiment, if a plurality of mobile phones each apply to the server and the obtained account number is registered in one recording device, as shown in FIG. Thus, the recording reservation operation can be performed from each of the plurality of mobile phones 112 A and 112 B. Therefore, it is possible to easily make a recording reservation by creating each account in the server by using the mobile phone owned by each family of the recording device 106 as a family.

  In this embodiment, the individual identification information of the recording device is transmitted to the recording device management unit of the server. Therefore, even if a different mobile terminal subscribes to a service with a different account number, the recording device management unit 244 (see FIG. 6) can determine that they are services that use the same recording device 106.

  Therefore, when displaying the program guide for each service of a different account in the program information providing service, it is possible to display whether or not a recording reservation has already been made for each recording device and avoid duplicate recording. That is, even when two mobile phones are used and the same recording device is used, a reservation made by one account can be viewed from the mobile phone of the other account.

  When the recording device 106 fails, the following processing is performed. If the recording device 106 breaks down, if a new recording device is prepared, the account information can be set for the new recording device simply by inputting the account number stored in the mail of the mobile phone 112. As a result, service is immediately available. At this time, it is assumed that the individual identification information of the server is updated.

  One recording device 106 can receive a recording reservation service by a separate program information service. In that case, the following operation is performed.

  As shown in FIG. 32, a plurality of mobile phones 112A and 112B create accounts in the user account management unit 250 through the recording device management units 244 of the plurality of servers 102A and 102B, and register each account number in one recording device 106. To do. By this operation, it is possible to receive different program information service services in one recording device 106.

  The above may be combined. Also in this case, a plurality of accounts corresponding to each mobile phone can be set, and a service corresponding to the combination of each mobile phone and each server can be received.

  In this system, the same recording device 106 can be controlled from a plurality of mobile phones using a plurality of program information service provider servers. An example is shown in FIG.

Referring to FIG. 32, this system includes a recording device 106 to which a TV monitor 110 is connected and has a remote controller 108. The recording device 106 can be connected to the network 104. The system further includes two program information service provider servers 102A and 102B, both of which can communicate with the recording device 106 via the network 104, a mobile phone 112A of a user who uses the program information service provider server 102A, and a program information service. and a mobile phone 112B of the user using the provider server 102 B. The mobile phones 112A and 112B can communicate with the program information service provider servers 102A and 102B via the wireless network 105, respectively.

  The program information service provider server 102A provides services from the first program information service provider, and the program information service provider server 102B provides services from the second program information service provider. These services are of the same type, but may be used to make a call with a mobile phone in a different manner, except for the content of communication with the recording device 106.

  In this system, one of a plurality of servers can be selected based on the account number. That is, as described with reference to FIG. 27, when an account number is set in the recording device 106, the recording device 106 selects a corresponding program information service provider server based on the upper two digits of the account number, and Request account information from When this server is selected, the program information service server DB 458 shown in FIG. 17 is referred to. In this embodiment, the program information service server DB 458 is held in, for example, a directory server jointly managed by the program information service industry, and is downloaded to the recording device 106 via the network.

  It goes without saying that the program information service server DB 458 may be set up using any other means. However, the contents of the program information service server DB 458 are always kept in a consistent state in the program information service industry that provides services based on a common standard, and servers of a plurality of service providers are confused. It is necessary not to have.

  In this system, a plurality of mobile phones 112A and 112B can subscribe to services of different servers. A plurality of accounts are set in one recording device 106, and the servers 102A, 102B and the recording device 106 communicate with each other using the account information, and exclusively control and use the I / O in the recording device 106. Since the specific method can be easily realized by using a known multi-user OS, details thereof will not be described here.

  In the system using the recording device 106, the program information service provider server 102, and the mobile phone 112 according to the present embodiment, a plurality of mobile phones 112 are used, and one program information service provider server 102 is used to The recording device 106 can also be used. The usage form is shown in FIG.

  In the program information service provider server 102 shown in FIG. 33, as shown in FIG. 34, the recording reservation records 750, 752 and the like of the recording reservation DB unit 246 include the individual identification information of the recording device and the mobile mail address. Therefore, the program information service provider server 102 can manage the recording reservation records 750, 752 and the like by any method according to account, individual identification information, or mobile mail address.

  For example, according to this system, the same recording device 106 can be associated with a plurality of mobile phones 112. For example, for a user who uses the mobile phone 112A, a recording reservation record can be extracted and displayed as a list based on the account information having the mobile mail address of the mobile phone 112A. Similarly, a recording reservation list or the like can be displayed to other users of the mobile phone 112B based on the account information having the mobile mail address of the mobile phone 112B.

  Further, for a plurality of mobile phones 112 associated with the same recording device 106, account information and recording reservation records corresponding to them can be extracted. Therefore, as shown on the display screen of the mobile phone 112A in FIG. 33, it is easy to display not only the recording reservation status of a user of a certain account but also the recording reservation status of another user who uses the same recording device as this account. Can be realized.

Furthermore, program information service provider server 102 according to the present embodiment, according to the recording device 106 and mobile telephone 112, the recording reservation record program information service provider server 102 includes the account number. Therefore, a plurality of recording devices 106 can be controlled by an account corresponding to one mobile phone 112.

  That is, if an account is created in the program information service provider server 102, when a new recording device is to be used, an existing account number is set for the recording device. Then, the new recording device can be automatically controlled by the mobile phone corresponding to the account number.

For example, as shown in FIG. 35, the system includes a plurality of recording devices 106A and 106B, and a plurality of mobile phones 112A and 112B for controlling them are used. Account number “3259 1131 1324” is assigned to both recording devices 106A and 106B. 4140 "and" 3124 0938 2321 4547 "are registered. Of these, the former corresponds to the mobile phone 112B, and the latter corresponds to the mobile phone 112A.

  Then, since the program information service provider server 102 selects a control partner based on the account number and the individual identification information of the recording device, it is possible to control any of the recording devices 106A and 106B from any of the mobile phones 112A and 112B. it can. Since the recording device is controlled using the mobile phone, the same service as the first device can be realized for the second recording device. In the form shown in FIG. 35, both the recording devices 106A and 106B periodically connect to the mail server unit of the program information service provider server 102 to receive the recording reservation mail. At this time, it is preferable to shift the timer activation time for starting reception of the recording reservation mail. Then, the recording reservation is preferentially performed for the recording device that can access the mail server unit first.

  If the hard disk capacity of the priority recording device is full, or if another channel has already been reserved at the same time, recording reservation using the first recording device cannot be performed. Therefore, the recording reservation mail is not deleted from the mail server unit of the program information service provider server 102. This recording reservation mail is processed by the second recording device. As a result, the program information service provider server 102 can realize substantially the same function as one recording device having a plurality of tuners.

  At this time, the recording capacity also corresponds to the total disk capacity of a plurality of recording devices. Moreover, e-mails relating to the success or failure of the reservation are returned to the same mobile mail address regardless of which recording device has been reserved. Therefore, the user can manage a plurality of recording devices in a unified and centralized manner using a single mobile phone.

  Next, when the program information service provider server 102, the recording device 106, and the mobile phone 112 according to the present embodiment are used, a plurality of accounts can be managed using one mobile phone 112. That is, referring to FIG. 36, it is assumed that there is one mobile phone 112 that can be used in the system. Consider a case in which a mobile mail address of the mobile phone 112 (for example, papa @ isp1) is separately subscribed to a program information service specialized in sports and a program information service specialized in entertainment. In FIG. 36, the program information service provider server 102 is shown as a single one, but may be plural.

  When the user of the mobile phone 112 subscribes to the program information service provider server 102, the account number assigned at that time is shown, for example, on the account number notification screen 782 in FIG. When subscribing to another program information service provider server, the assigned account number is different. For example, an account number notification screen 780 shown in FIG. 36 is displayed.

  In this case, as is clear from the above description, each mobile phone 112 can receive each service. In the example of FIG. 36, this user has subscribed to “sports” and “entertainment” services, and different account numbers are issued from the user account management unit of the server.

  In the service name item of account information, the name of the subscribed service is stored as a character string by the program information service provider server 102 when the user subscribes.

  The user of the mobile phone 112 can acquire the account number of each service and register it in the recording device 106. With this registration, it is possible to log in to each service from the mobile phone and make a recording reservation for the same recording device 106 using different services. Furthermore, these recording-reserved programs can be distinguished and displayed by service names 770 and 772 displayed on the screen of the mobile phone 112 in FIG.

  In the present embodiment, it is assumed that the service name field is a character string. However, the present invention is not limited to such an embodiment, and this may be replaced with a URL indicating the location of an image on the network. Alternatively, a field of service image in addition to the service name may be added to the account information shown in FIG. Since the service image field is a URL character string indicating an image, it is possible to easily identify the category of the recording reservation data by displaying the service image along with the recording reservation data.

  Further, when a URL is stored in the service name field, when recording reservation data is displayed, it is determined how to display the data transferred from the URL in the same way as a browser displaying a normal HTML document. be able to. For example, if the data specified by the URL is text data, it may be displayed as a normal character string. If the data specified by the URL is an image file, the data may be decoded and displayed according to an image format that can be determined by the extension.

  According to the present embodiment, the success or failure of the reservation is returned to the mobile mail address. Therefore, even if a certain user subscribes to a plurality of services, the user can be managed in a unified and centralized manner with a single mobile phone. It is also possible to display the recorded data separately by service name.

The system using the program information service provider server 102 and the recording device 106 according to the present embodiment can be used from a server other than a mobile phone that is an operation terminal. Therefore, if there is a request from the user of the mobile phone, the program information service provider server 102 returns the account information corresponding to the mobile phone to the mobile phone and displays it on the HTML browser of the mobile phone.

FIG. 37 shows an example in which the recording mail address and the recording reservation password in the account information are displayed on the screen 796 of the mobile phone 112. As for this information, an account information request screen 790 is displayed on the mobile phone 112, and an account information request 792 is sent to the program information service provider server 102 by clicking the “Yes” portion. In response to this request, the program information service provider server 102 returns account information 794 to the mobile phone 112. The mobile phone 112 displays this account information as a screen 796 .

  The user 800 visually checks this information (802) and registers it in the recording reservation mail service of the third party's program information service provider, so that the third party's server stores the recording reservation password for the recording mail address. A recording reservation mail is issued, and the mail is sent to the recording mail address to which it was originally subscribed. Therefore, the original recording reservation service can be used via the third party recording reservation service.

  As described above, when the program information service provider server 102 transmits the account information to the mobile phone 112 and displays it in response to the request, a device other than the mobile phone, such as a personal computer 798, can be used as the operating device. . For example, a login screen 806 for a personal computer is prepared by the program information service provider server 102 and transmitted to the personal computer 789 (814) for display. Of the account information, the personal computer 798 inputs the recording mail account and the recording reservation password in the login name field 810 and the password field 812, and transmits them to the server 102 (816). As a result, the personal computer 798 can log in to the WEB version program information service of the server 102. As a result, a screen 820 after login is displayed on the screen of the personal computer 798.

Account information is specified by a recording mail account name and a recording mail password, and a recording reservation password, a recording reservation mail address, and a POP / SMTP mail server are also specified. Therefore, the user can also issue a recording reservation mail from the HTML program guide via the personal computer 798 as with a mobile phone. When “Email recording reservation” displayed on the screen 820 of FIG. 37 is clicked, a recording reservation mail is transmitted from the personal computer 798 to the mail server unit of the server 102 as in the case of the operation by the mobile phone ( 818 ). This email is further transmitted to the recording device 106 when the recording device 106 checks the recording reservation email (820).

  A personal computer has a larger screen and higher resolution than a mobile phone. Therefore, more information can be displayed than a mobile phone. For example, detailed program information can be displayed with images. According to the present embodiment, it is possible to use the program information service using a personal computer without taking the trouble of acquiring a new mail account and setting a recording reservation password.

  Referring to FIG. 38, as described above, the recording management unit 450 of the recording device 106 shown in FIG. 17 sends a recording reservation reply mail to the mobile mail address in step 566 of FIG. At this time, the sender mail address is the recorded mail address in the account information extracted from the account management unit, and the received mail address is the mobile mail address. The mail subject includes a status and a program name. For example, “Subject: [Reservation complete] News show for dad”.

  Thus, as shown in FIG. 38, in the received mobile phone 112, in the received mail list 840, the user 800 can immediately determine that the recording reservation has been completed, and can also check the program name.

  As described above, by using the mobile phone, the complicated account setting for controlling the recording device can be acquired and set by the recording device 106 from the server 102 via the network. For this reason, there is an advantage that an account associated with a mobile phone mail address can be set without error.

  The server 102 can collect the mail address of the mobile phone that the user always wears without error, not the mail address of the personal computer. Therefore, it is possible to notify the user of recommended programs by e-mail or to use this information for sales activities such as guidance to the electronic commerce market.

  In the above embodiment, no special communication means is required between the mobile phone 112 and the recording device 106. The user simply inputs the account number displayed on the mobile phone 112 into the recording device 106, and the operation is simple.

  For example, in the above-described embodiment, up to three accounts can be registered in one recording device 106. Therefore, it is only necessary to perform a registration operation on each of a plurality of mobile phones 112 in the family. If you change your phone, you can leave the previous account and overwrite it with a new one.

  With the above mechanism, there is an advantage that the mobile phone, the server, and the recording device can be associated with each other with a simple operation. Although the embodiment has been described on the assumption that the account information is a number, an alphabet key may be used if a key exists in the remote controller. It should not be interpreted as being limited to numbers.

According to the present embodiment, the following ripple effect is further obtained. In other words, a web browser using a mobile phone can subscribe to a paid service using an authentication system prepared on the mobile network side. The paid service server may be contracted with the gateway administrator of the mobile network. This account is based on the server service for mobile phones, and if the program information service is a paid service, the paid service can be received by the recording device by the simple procedure disclosed in the present embodiment. become.
Also different services of prices have been performed in the same server computer, joined to each of the pay service from the cellular phone in the method of this embodiment, by inputting an account number in the recording device, simply the service Are received by the recording device 106. Therefore, the recording device 106 does not need any charging mechanism.

  Next, in the present embodiment, the recording device 106 may be connected to the Internet where the server exists via a NAT (Network Address Translation) router. In other words, the present embodiment is an architecture that establishes a TCP / IP connection such as HTTP and SMTP / POP from the recording device 106 to the server 102. Therefore, the recording device 106 can make a recording reservation, mail notification to a mobile phone, and information update to a server from a network in the private address space of the Internet via a NAT (network address conversion) router.

  In this embodiment, as a means for delivering the recording reservation information from the server 102 to the recording device 106, the mail server unit of the server is used, and the POP protocol, which is a mail protocol, is used with the recording device 106. did. However, the present invention is not limited to such an embodiment, and can be implemented by the basic authentication protocol of the HTTP protocol. In this case, since the recording device 106 is authenticated by the server and obtains recording reservation information, a recording reservation password is not required. In the basic authentication protocol of the HTTP protocol, the recording device 106 accesses the server by using an account name and a password, and the server 106 authenticates the recording device 106 based on the account name and provides the recording reservation information. That's fine.

  Further, according to the present embodiment, the account information related to the recording reservation is generated by the server. Therefore, the server can record the program reserved for recording by the user using the recording reservation service. As a result, it is easy to extract the user's preference for the program reserved for recording and present the recording reservation candidate that matches the user's preference on the mobile phone. Easy.

  In the above embodiment, the recording device has been described as an example. However, the present invention is not limited to the recording device as long as it is a network device connected to a network and having a display device. The recording device is controlled by a recording command from the service provider, but the network device receives a specific URL instead of the recording command, accesses it by a browser installed in the network device, and displays it on the TV screen Also in the examples, the service cooperation technology by the mobile device and the network device of the present invention is effective. In this case as well, information can be displayed on the network device simply by operating the mobile phone.

[Embodiment 2]
In the first embodiment described above, the user visually checks the account number displayed on the mobile phone and inputs it again to the recording device 106. According to this method, the recording device 106 can be set without inputting a large amount of information. However, the present invention is not limited to such an embodiment. When setting the account information in the recording device, the method as in the second embodiment can be adopted.

  In the second embodiment, it is assumed that the mobile phone 112 has a proximity wireless communication function such as an infrared data communication function. Recent mobile phones are remarkably multifunctional, and many have such functions. The recording device 106 usually has such a function. When such a function is used, the user can input the account number into the recording device 106 directly from the mobile phone using the communication function described above, instead of manually inputting the account number into the recording device 106.

  In addition, the account information itself can be transmitted from the program information service provider server 102 to the mobile phone, and all of the information can be transmitted from the mobile phone to the recording device 106. FIG. 39 shows a configuration example of a system using such functions. In addition, FIG. 40 shows a flowchart of a program executed by the mobile phone 112 at this time.

  In the present embodiment, it is assumed that account information is already set in the program information service provider server 102 by a procedure between the mobile phone 112 and the program information service provider server 102 in advance. However, since communication between the recording device 106 and the program information service provider server 102 has not yet been performed, it is assumed that the individual identification information of the recording device 106 is not set in the account information.

  The program information service provider server 102 prepares account information setting software that implements a function for the mobile phone 112 to communicate with the recording device 106 by infrared communication. Then, the URL indicating the location of the software is written in a mail addressed to the mobile phone 112 and transmitted. By displaying this e-mail on the screen 850 of the mobile phone 112 and clicking a link to the corresponding URL, the software is downloaded to the mobile phone 112 (852). After the download, the software is automatically activated, and the user's manual work is omitted by performing infrared communication with the recording device, so that the account information can be safely and definitely input to the recording device 106 (854).

  As a standard for infrared data communication, a standard based on IrDA is mounted on a mobile phone as a standard, and it is easy to use it. Some overseas mobile phones use other standards, and by using them, communication can be made between the mobile phone and the recording device.

  The recording device 106 that has received the account information sets itself according to the information, and then transmits its individual identification information to the program information service provider server 102 (856). Thereby, the individual identification information of the recording device 106 can be set in the account information of the program information service provider server 102.

  FIG. 40 shows a flowchart of a program executed in mobile phone 112 in the present embodiment. Referring to FIG. 40, first, in step 870, confirmation mail 850 (see FIG. 39) from program information service provider server 102 is received. In step 872, the account information setting control software is loaded from the URL included in the mail and activated. Thereafter, after executing the account information setting control software, the program ends.

  FIG. 41 shows a flowchart of this account information setting control software. Referring to FIG. 41, in step 874, the program information service provider server 102 is connected to the recording device management unit, and the account information of the user of the mobile phone 112 is acquired from the program information service provider server 102. In step 876, a message for instructing the user to display the recording device 106 as the account information setting screen is displayed on the screen of the mobile phone 112. In step 878, the account information is transferred to the account management unit of the recording device 106 through the Ir transmission / reception unit of the recording device 106 using the IrDA interface of the mobile phone 112. Finally, in step 880, the recording device 106 is controlled to connect to the program information service provider server 102, and the account number set in the recording device 106 and the individual identification information of the recording device 106 are transmitted. Thereby, the recording device 106 notifies the program information service provider server 102 that the account information of the account number has been set in the program information service provider server 102.

  According to the system according to the second embodiment, account information can be automatically transferred and set from the mobile phone 112 to the recording device 106 using a program prepared by the program information service provider server 102. There is no need for the user to visually input the account number into the recording device 106. Therefore, the account number can be set in the recording device 106 with a simpler process for the user. Since the account information itself is also transferred from the program information service provider server 102 to the recording device 106 via the mobile phone 112, no error occurs in the account information. Further, since the recording device 106 finally notifies the program information service provider server 102 of the completion of account information registration, the program information service provider server 102 can easily confirm that the account information has been registered in the recording device 106. Can be confirmed.
