Description

  The present invention relates to an information processing system, a recording device, and a communication device, and in particular, by using effectively EPG (Electronic Program Guide) data and other information possessed by a recording device such as a hard disk recorder, it is highly convenient. The present invention relates to an information processing system, a recording apparatus, and a communication apparatus that can provide a recording apparatus.

  In recent years, DVRs (Digital Video Recorders) such as hard disk recorders and hybrid recorders of hard disks and DVDs (Digital Versatile Discs) are rapidly spreading.

  Furthermore, on the Internet, an EPG server, which is a server that provides an EPG web page called iEPG, is spreading. Some of these EPG servers provide not only a web page for browsing an EPG but also a service for controlling recording reservation of a program (see, for example, Patent Document 1).

  That is, in an EPG server that provides a service for controlling program recording reservation, for example, when a user accesses the mobile phone from an outside location, an EPG web page is provided to the user's mobile phone. When the user operates the mobile phone so as to make a reservation for recording a desired program by looking at the EPG web page, the channel (number of the program or the broadcast station for which the recording reservation is made) on the EPG server. Name, etc.), broadcast date, broadcast start time, broadcast end time, title, description of the content of the program, etc., the user information that identifies the user who is the owner of the mobile phone, for example, Are stored in association with each other.

  On the other hand, for example, a DVR installed in a user's house (user's house) is polling the EPG server, and the EPG server stores program information associated with user information of the user of the mobile phone If so, the program information is transmitted to the DVR in response to polling from the DVR.

  The DVR receives the program information from the EPG server, and starts recording the program of the channel in the program information when the time indicated by the broadcast start time in the program information comes.

JP 2001-309285 A.

  As described above, in the past, for example, in order to view an EPG from outside, a user needs to access an EPG server by a mobile phone and receive an EPG web page from the EPG server. It was.

  Therefore, when such an EPG server is installed and, for example, the number of accesses to the EPG server increases, it is necessary to increase the number of EPG servers.

  In addition, the EPG server needs to update the EPG provided as a web page as appropriate, but if the update is slow, the user cannot browse the latest EPG.

  Further, for example, when the recording reservation of the same program as the program that the user intends to make a recording reservation has already been made by the family directly operating the DVR installed in the user's house, the user No need to make a reservation. However, since the user who has gone out does not know that the recording reservation has already been made, there is a possibility that the user will operate the mobile phone and make a useless recording reservation.

  On the other hand, in terrestrial analog broadcasting, EPG data (EPG data) is transmitted superimposed on broadcast waves, and DVRs that receive, store and display the EPG data are manufactured and sold. Here, the EPG data includes, for example, program information of each program (channel, broadcast date, broadcast start time, broadcast end time, title, description of program contents).

  In addition, EPG data is also broadcast in terrestrial digital broadcasting, and DVRs that can handle EPG data from digital broadcasting are appearing as DVRs compatible with digital broadcasting.

  Since digital broadcasting can transmit EPG data more quickly than analog broadcasting, the DVR can quickly acquire the latest EPG data. In this case, the latest EPG data is stored in the DVR, but the EPG server may not be able to provide the latest EPG while the EPG web page is being updated.

  Therefore, as described above, when it is possible to quickly acquire EPG data in the DVR, the mobile phone is installed in its own home rather than receiving the provision of EPG from the EPG server. Users who have received an EPG from a DVR can view the latest EPG.

  Further, the DVR stores information on the recording reservation that has already been performed, and if the mobile phone can acquire and confirm the recording reservation information from the DVR, the user is wasted as described above. There is no need to schedule recording.

  The present invention has been made in view of such a situation, and makes it possible to provide a highly convenient recording apparatus by effectively using information included in a recording apparatus such as a DVR. is there.

  According to the present invention, it is possible to effectively use information included in a recording apparatus.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a configuration example of an embodiment of a recording reservation system to which the present invention is applied.

  In the recording reservation system of FIG. 1, a broadcasting station 1 is a broadcasting station that performs television broadcasting, for example, and broadcasts video data, audio data, and EPG data as programs using, for example, digital broadcasting waves. In FIG. 1, the broadcasting station 1 performs wireless broadcasting, but the broadcasting station 1 may perform wired broadcasting.

  An antenna 11, a DVR 12, a TV (Television) receiver 13, and a router 14 are installed in the user A's house, which is the user A's house.

  The antenna 11 receives a digital broadcast wave from the broadcast station 1 and supplies broadcast signals such as program data (program video data and audio data) and EPG data to the DVR 12. The DVR 12 receives the broadcast signal supplied from the antenna 11 and records (records) (stores) program data and EPG data included in the broadcast signal.

  Further, the DVR 12 reproduces the recorded program data and supplies it to the TV receiver 13. That is, the DVR 12 is connected to the TV receiver 13, and the program data reproduced on the DVR 12 is supplied to the TV receiver 13. The TV receiver 13 displays an image corresponding to video data as program data supplied from the DVR 12, and outputs sound corresponding to the audio data.

  Further, the DVR 12 is connected to the network 21 via the router 14 and performs communication via the router 14 and the network 21.

  The router 14 is connected to the DVR 12 and further to an electronic device (not shown) in the user A's home. Further, the router 14 is connected to the network 21, and performs routing control and the like for the network 21 (so-called home network) constituted by electronic devices such as the DVR 12 in the user A's house and the network 21.

  Here, the network 21 is, for example, the Internet, and a global IP (Internet Protocol) address is assigned to the side of the router 14 to which the network 21 is connected (so-called WAN (Wide Area Network) side). Yes. Also, a private IP address is assigned to the side of the router 14 to which the electronic device in the user A home such as the DVR 12 is connected (so-called LAN (Local Area Network) side). Furthermore, a private IP address is also assigned to the electronic devices in the user A's home including the DVR 12 connected to the router 14.

  Therefore, in order for the DVR 12 to communicate with the network 21 that is the Internet via the router 14, a technique called NAT (Network Address Translation) and, if necessary, IP masquerade is required. 14 is assumed to have a NAT function and, if necessary, an IP masquerade function.

  A base station 22 managed and operated by a so-called carrier company of mobile phones is connected to the network 21. The base station 22 controls communication with a mobile phone in a cell (zone) that is in a range in which it can communicate with itself (the base station 22), whereby a mobile phone in the cell and other mobile phones Communication (call) with is possible. Further, the base station 22 enables communication between the mobile phone in the cell and the network 21.

  The mobile phone 31 includes a display 32 on which various information is displayed, an operation unit 33 including keys and the like that are operated when a telephone number is input, and the like, and performs communication and other processing for a call. Do. The

  Here, in FIG. 1, the user A who is out of the user A's home is located in the cell of the base station 22. Furthermore, the user A has a mobile phone 31 of a carrier company that manages and operates the base station 22. Accordingly, the mobile phone 31 possessed by the user A can communicate with another mobile phone (not shown) via the base station 22. In addition, the mobile phone 31 can communicate with a server on the network 21 that is the Internet via the base station 22. Further, the mobile phone 31 can communicate with the DVR 12 via the router 14 of the user A's house connected to the network 21.

  In order for the mobile phone 31 to communicate with the DVR 12 via the router 14, it is necessary to perform so-called NAT traversal. Here, in order to simplify the explanation, it is assumed that the mobile phone 31 recognizes the method of NAT over the router 14. That is, for example, the router 14 is a packet (IP packet) addressed to a specific port among IP packets addressed to the router 14 (IP packet addressed to the IP address assigned to the WAN side of the router 14) from the network 21. Is transmitted to the DVR 12 as a packet addressed to the DVR 12, and the mobile phone 31 recognizes the specific port and the global IP address assigned to the router 14.

  In the recording reservation system configured as described above, a digital broadcast wave from the broadcast station 1 is received by the antenna 11, and a broadcast signal obtained as a result is supplied to the DVR 12. The DVR 12 receives a broadcast signal supplied from the antenna 11 and stores (records) EPG data included in the broadcast signal.

  As shown in FIG. 2, the EPG data stored in the DVR 12 can be viewed (viewed) on the TV receiver 13 in the home of the user A, or acquired by the mobile phone 31 possessed by the user A who is away from home. You can also browse.

  That is, when the user A in the user A's home operates a remote controller (remote commander) (not shown) of the DVR 12 so as to display the EPG, the DVR 12 uses, for example, FIG. An EPG screen 41 as shown in FIG. 6 is created and supplied to the TV receiver 13 for display.

  In addition, when the user A who is out of the office operates the operation unit 33 of the mobile phone 31 to display the EPG, the mobile phone 31 communicates with the DVR 12 via the base station 22, the network 21, and the router 14. As a result, the EVR is requested to the DVR 12. In response to the request, the DVR 12 creates a program guide list screen 51, which is an EPG web page, for example, as shown in FIG. And transmitted to the mobile phone 31 via the base station 22. The mobile phone 31 receives the program guide list screen 51 from the DVR 12 and displays it on the display 32.

  Here, in FIG. 2, the EPG screen 41 displayed on the TV receiver 13 and the program guide list screen 51 displayed on the display 32 of the mobile phone 31 are created from the same EPG data. The contents (amount of information) can be the same. The configurations (layouts) of the EPG screen 41 and the program guide list screen 51 may be the same or different.

  However, if the program guide list screen 51 displayed on the display 32 of the mobile phone 31 is a screen (image) having the same configuration as the EPG screen 41, the size of the display 32 of the mobile phone 31 is generally that of the TV receiver 13. Since it is smaller than the size of the display screen, the display of the program guide list screen 51 on the mobile phone 31 may be difficult to see. Therefore, it is desirable that the program guide list screen 51 displayed on the display 32 of the mobile phone 31 is configured so as not to be difficult to see even with a small display such as the display 32.

  Next, FIG. 3 and FIG. 4 show display examples of screens displayed on the display 32 of the mobile phone 31.

  For example, the DVR 12 has a web server function, the mobile phone 31 has a web browser function, and the user A operates the operation unit 33 of the mobile phone 31 to perform an EPG on the DVR 12. , The DVR 12 creates a program guide list screen 51 as a web page from the EPG data already stored in the DVR 12 and transmits it to the mobile phone 31.

  The mobile phone 31 receives and displays the program guide list screen 51 from the DVR 12. That is, on the mobile phone 31, a program guide list screen 51 as shown first from the left in FIG.

  In the program guide list screen 51 of FIG. 3, information on programs broadcast on the channel “NHK General” is displayed. In FIG. 3, as program information, a channel (name), a broadcast date of the program, a broadcast start time, a broadcast end time, a title, and the like are displayed.

  The program guide list screen 51 can be scrolled in the horizontal direction. For example, when the operation unit 33 of the mobile phone 31 is operated so as to perform the horizontal scroll, the program guide list screen 51 is displayed. In response to the operation, the screen is scrolled in the horizontal direction, whereby information on programs broadcast on other channels is displayed on the display 32. The program guide list screen 51 can be scrolled in the vertical direction. For example, when the operation unit 33 of the mobile phone 31 is operated so as to scroll in the vertical direction, the program guide list screen 51 is displayed. In response to the operation, the screen is scrolled in the vertical direction, whereby information on a program broadcast on the same channel in another time zone is displayed on the display 32.

  Of the program information displayed on the program guide list screen 51, for example, the program title (display) is linked to the program details screen 52, which is a web page describing the contents of the program. Yes. When the user A operates the operation unit 33 of the mobile phone 31 to select (click) a desired title displayed on the program guide list screen 51, a request for the program details screen 52 corresponding to the title is transmitted to the DVR 12. Is done.

  In response to the request for the program detail screen 52 from the mobile phone 31, the DVR 12 creates the program detail screen 52 from the EPG data already stored in the DVR 12 and transmits it to the mobile phone 31. The mobile phone 31 receives and displays the program detail screen 52 from the DVR 12. That is, on the mobile phone 31, a program detail screen 52 as shown second from the left in FIG.

  On the program details screen 52 of FIG. 3, a summary of the explanation of the program channel, broadcast date, program performer, and program content is displayed.

  For example, when the user A looks at the program details screen 52 and wishes to make a recording reservation for the program introduced on the program details screen 52, the operation unit of the mobile phone 31 is instructed to instruct the recording reservation for the program. 33 is operated.

  The cellular phone 31 displays a reservation screen 53 on the display 32 for setting program recording information, which is information necessary for reserved recording, in response to a recording reservation instruction.

  That is, the third (rightmost) from the left in FIG.

  The reservation screen 53 includes a “date” field, a “time” field, a “channel” field, a “recording mode” field, an “extension” field, and a “protect” field.

  In the “date” column, the broadcast date of the program that is the target of the recording reservation (hereinafter referred to as the reservation target program as appropriate), the broadcast start time and the broadcast end time of the reservation target program are displayed in the “time” column. In the “Channel” column, the channels on which the reservation target program is broadcast are displayed. The reservation target program is a program introduced on the program details screen 52 displayed on the display 32 when the recording reservation instruction is given. For the reservation target program, the “date” column, “time” The data displayed in the column and the “channel” column may be acquired from, for example, information (EPG data) used to display the program guide list screen 51, or may be acquired from the DVR 12 anew. .

  In the “recording mode” column, a recording mode for recording the reservation target program is displayed. In FIG. 3, “SP” representing the recording mode of recording with standard image quality (sound quality) is displayed. Other recording modes include, for example, recording modes with low image quality and high sound quality.

  In the “extension” column, the reservation target program is a program after a program such as a baseball broadcast, for example, and indicates whether or not the recording time of the reservation target program is extended in case the baseball relay is extended. Extended information is displayed. In FIG. 3, “none” indicating that the recording time is not extended is displayed.

  In the “Protect” column, protect information indicating whether or not to protect the program (the video data and the audio data) after the reservation target program is recorded is displayed. In FIG. 3, “None” indicating that no protection is provided is displayed.

  Here, in FIG. 3, “SP” of the recording mode displayed in the “Recording mode” column, “None” of the extension information displayed in the “Extension” column, and “Protect” column are displayed. “None” in the protection information is, for example, a default setting, and these settings can be changed by the user operating the operation unit 33 of the mobile phone 31. In the reservation screen 53, the settings of the “date” field, the “time” field, and the “channel” field can also be changed by the user operating the operation unit 33 of the mobile phone 31.

  When the user A wishes to make a recording reservation for the reservation target program with the content displayed on the reservation screen 53, the user A operates the operation unit 33 of the mobile phone 31 to confirm the recording reservation. In this case, the mobile phone 31 transmits information set (displayed) on the reservation screen 53 to the DVR 12 together with a recording reservation request (reservation request) as program recording information necessary for reserved recording of the reservation target program. .

  In response to a reservation request from the mobile phone 31, the DVR 12 performs a recording reservation process for reserving recording of a reservation target program (recording reservation) using program recording information transmitted together with the reservation request.

  In the mobile phone 31, as described above, the EPG data already stored in the DVR 12 (such as the program guide list screen 51 created from the DVR 12) is acquired and displayed. It is also possible to access an EPG server (not shown) on the network 21, which is the Internet, to acquire and display the EPG.

  That is, for example, as shown in FIG. 4, the cellular phone 31 can acquire and display EPG data from the DVR 12, and can also acquire and display EPG from the EPG server.

  In addition, the mobile phone 31 can also acquire and display information other than EPG data from the DVR 12, that is, for example, information indicating the recording reservation status (reservation status information). In this case, the user sees the recording reservation status in the DVR 12 from the outside, and whether or not the recording reservation of the program to be performed has already been performed, or the recording reservation of the program is other than It can be checked whether or not it overlaps with the program recording reservation.

Here, examples of information to be displayed on the OSD include a channel (representing number), volume (representing information), EPG (EPG screen 41 (FIG. 2)), a reservation list and a recorded list, which will be described later. .

  The audio encoder 104 decodes the audio data packet from the demultiplexer 102 and outputs the resulting audio data from the audio output terminal 106. The audio output terminal 106 is connected to, for example, the TV receiver 13, and therefore the TV receiver 13 outputs sound corresponding to the audio data obtained by the audio decoder 104.

  The communication I / F 107 is composed of, for example, a NIC (Network Interface Card). The communication I / F 107 is connected to the router 14 (FIG. 1) and controls communication with the router 14. Note that the communication I / F 107 can perform communication by either wireless or wired, for example.

  The CPU 108 executes a program stored in the ROM 111, a program recorded in the HD 117 and loaded into the RAM 112, and a program stored in the EEPROM 113, thereby controlling various blocks constituting the DVR 12 and performing various other processes. . Further, the CPU 108 is supplied with an operation signal corresponding to a user operation from the operation panel 109 or the light receiving unit 110, and also performs processing corresponding to the operation signal.

  The operation panel 109 is composed of various buttons and the like provided on the housing of the DVR 12. When the operation panel 109 is operated by the user, the operation panel 109 supplies an operation signal corresponding to the operation to the CPU 108.

  The light receiving unit 110 receives (receives) a radio signal (for example, infrared rays) from a remote controller (not shown) of the DVR 12 and supplies the received signal to the CPU 108. In other words, when the remote controller is operated, the remote controller wirelessly transmits an operation signal corresponding to the operation, and the light receiving unit 110 receives the operation signal transmitted by the remote controller and supplies it to the CPU 108.

  The ROM 111 stores, for example, a program to be executed first when the DVR 12 is turned on. A program to be executed by the CPU 108 is loaded into the RAM 112 from the HD 117 via the bus. In addition, the RAM 112 stores other data necessary for the operation of the CPU 108. The EEPROM 113 stores information that should be retained even after the power of the DVR 12 is turned off. Information stored in the EEPROM 113 includes, for example, a channel that has been selected (selected) immediately before the power of the DVR 12 is turned off. When the power supply of the DVR 12 is turned on next time, the channel that was selected immediately before the power supply of the DVR 12 is turned off is selected again based on the information stored in the EEPROM 113.

  The disk drive 114 drives a disk 115 as a recording medium that can be attached to and detached from the disk drive 114, thereby recording data supplied via the bus on the disk 115, and data (programs) recorded on the disk 115. Are output and output on the bus. Here, as the disc 115, for example, a DVD or a Blu-ray disc can be employed.

  The HD drive 116 has a built-in HD 117 and drives the HD 117. As a result, the HD drive 116 records the data supplied via the bus on the HD 117, reads out the data recorded on the HD 117, and outputs the data on the bus.

  Here, various application programs for the DVR 12 to perform operations described later are installed in the HD 117. FIG. 5 shows a web server program (web server program) as one of such application programs. When the CPU 108 executes the web server program, the DVR 12 functions as a web server. Although not shown, the HD 117 is installed with an OS (Operating System) program in addition to the application program.

  The HD 117 also records EPG data supplied from the demultiplexer 102 via the bus, as well as a reservation list and a recorded list, which will be described later.

  Further, in the HD 117, a program is recorded, that is, a program packet is recorded.

  For example, the encoder 118 encodes video data and audio data input from an external input terminal (not shown), and outputs the encoded result on the bus. The encoding result of the video data and audio data output by the encoder 118 on the bus is supplied to, for example, the HD drive 116 and recorded in the built-in HD 117.

  In the case described above, program packets and the like are recorded (recorded) on the HD 117, but program packets and the like can also be recorded on the disk 115 by the disk drive 114. Further, a packet of a program recorded on one of the disc 115 or the HD 117 can be copied or moved to the other.

  Here, the program executed by the CPU 108 can be recorded in advance in the ROM 111, the EEPROM 113, or the HD 117 as a recording medium built in the DVR 12.

  Alternatively, the program can be stored (recorded) temporarily or permanently in a disk 115 that is a removable recording medium or a semiconductor memory (not shown). Such a disk 115 and semiconductor memory can be provided as so-called package software.

  Furthermore, the program is installed in the DVR 12 from the disk 115 or the like, and is transferred from the download site to the DVR 12 via a digital satellite broadcasting artificial satellite, or a network 21 such as a LAN (Local Area Network) or the Internet. The program can be transferred to the DVR 12 by wire, and the DVR can receive the program transferred in this way by the communication I / F 107 and install it in the built-in HD 117.

  Next, FIG. 6 shows a configuration example of the mobile phone 31 of FIG.

  The mobile phone 31 has a power control circuit 251, an operation input control unit 252, an image encoder 253, a camera interface unit 254, a display control unit 255, an image for the main control unit 250 that comprehensively controls each unit constituting the mobile phone 31. A decoder 256, a demultiplexing unit 257, a recording / reproducing unit 224, a modulation / demodulation circuit unit 258 and an audio codec 259 are connected to each other via a bus.

  The main control unit 250 includes a CPU 201, a ROM 202, a RAM 203, and an EEPROM 204. The CPU 201 executes a program stored in the ROM 202, a program loaded in the RAM 203, and a program stored in the EEPROM 204, thereby The control of each part and other processes are performed via

  Here, the program executed by the CPU 201 can be installed in advance in the ROM 202 or the EEPROM 204. In addition, the program can be downloaded to the mobile phone 31 by communication via the base station 22 and installed in the EEPROM 204. Furthermore, the program can be recorded in a Memory Stick (trademark) 223, read by the recording / playback unit 224, and installed in the EEPROM 204.

  The power supply circuit unit 251 supplies power to each unit from a battery pack (not shown) when an end call (not shown) and a power key in the operation unit 33 are turned on by a user operation. 31 is activated into an operable state.

  Based on the control of the main control unit 250, the mobile phone 31 converts the audio signal collected by the microphone 221 in the voice call mode into digital audio data by the audio codec 259, and performs spread spectrum processing on the modulation / demodulation circuit unit 258. Then, after the digital / analog conversion process and the frequency conversion process are performed by the transmission / reception circuit unit 262, the signal is transmitted via the antenna 214.

  Further, the cellular phone 31 amplifies the received signal received by the antenna 214 in the voice call mode, performs frequency conversion processing and analog-digital conversion processing, performs spectrum despreading processing by the modulation / demodulation circuit unit 258, and performs analog speech by the voice codec 259. After being converted into a signal, this is output via the speaker 217.

  Furthermore, when the mobile phone 31 transmits an e-mail in the data communication mode, the text data of the e-mail input by operating the operation key 219 and the jog dial 222 constituting the operation unit 33 is sent via the operation input control unit 252. It is sent to the main control unit 250.

  The main control unit 250 performs spread spectrum processing on the text data in the modulation / demodulation circuit unit 258, performs digital analog conversion processing and frequency conversion processing in the transmission / reception circuit unit 262, and then transmits the text data to the base station 22 (FIG. 1) via the antenna 214. To do.

  On the other hand, when receiving an e-mail in the data communication mode, the cellular phone 31 performs a spectrum despreading process on the received signal received from the base station 22 via the antenna 214 by the modulation / demodulation circuit unit 258 to obtain the original text data. Is restored and displayed as an e-mail on the display 32 via the display control unit 255.

  Thereafter, the cellular phone 31 can also record the received e-mail in response to the user's operation on the Memory Stick (trademark) 223 via the recording / reproducing unit 224.

  On the other hand, when transmitting image data in the data communication mode, the mobile phone 31 supplies image data captured by a CCD (Charge Coupled Device) camera 216 to the image encoder 253 via the camera interface unit 254. Note that image data captured by the CCD camera 216 can be directly displayed on the display 32 via the camera interface unit 254 and the display control unit 255.

  The image encoder 253 converts the image data supplied from the CCD camera 216 into encoded image data by compressing and encoding the image data using a predetermined encoding method such as MPEG (Moving Picture Experts Group) 2 or MPEG4. Is sent to the demultiplexing unit 257.

  At the same time, the mobile phone 31 sends the sound collected by the microphone 221 during imaging by the CCD camera 216 to the demultiplexing unit 257 as digital audio data via the audio codec 259.

  The demultiplexing unit 257 multiplexes the encoded image data supplied from the image encoder 253 and the audio data supplied from the audio codec 259 by a predetermined method, and the modulation / demodulation circuit unit 258 spectrums the resulting multiplexed data. The signal is subjected to spreading processing, subjected to digital / analog conversion processing and frequency conversion processing by the transmission / reception circuit unit 262, and then transmitted through the antenna 214.

  Note that the cellular phone 31 can transmit electronic mail, image data, and other data of voice data in the data communication mode. That is, in the mobile phone 31, for example, when the operation key 219 or the jog dial 222 constituting the operation unit 33 is operated, data corresponding to the operation is supplied to the main control unit 250 via the operation input control unit 252. The

  The main control unit 250 performs spread spectrum processing on the data from the operation input control unit 252 by the modulation / demodulation circuit unit 258, performs digital analog conversion processing and frequency conversion processing by the transmission / reception circuit unit 262, and then performs the base station 22 via the antenna 214. (FIG. 1).

  Further, the mobile phone 31 can receive web pages and other data in the data communication mode.

  That is, when the mobile phone 31 transmits, for example, data requesting a web page to the data communication mode as described above, the web page data is transmitted via the base station 22 (FIG. 1) in response to the request. Therefore, the web page data is received by the transmission / reception circuit unit 262 and the modem circuit unit 258 via the antenna 214. The transmission / reception circuit unit 262 and the modulation / demodulation circuit unit 258 process the received Web page data as described above, and send the processed data to the main control unit 250.

  The main control unit 250 interprets web page data and creates a screen (image) based on the interpretation. This screen is supplied from the main control unit 250 via the display control unit 255 to the display 32 and displayed.

  That is, in the main control unit 250, at least a web browser program is installed in the EEPROM 204, and by executing the program, the CPU 201 functions as a web browser and interprets web page data.

  Also, the mobile phone 31 can receive moving image file data linked to, for example, a web page in the data communication mode. In this case, the received signal received from the base station 22 via the antenna 214 is subjected to spectrum despreading processing by the modulation / demodulation circuit unit 258, and multiplexed data obtained as a result is sent to the demultiplexing unit 257.

  The demultiplexer 257 separates the multiplexed data into encoded image data and audio data, supplies the encoded image data to the image decoder 256 via the bus, and supplies the audio data to the audio codec 259. Supply.

  The image decoder 256 generates reproduced moving image data by decoding the encoded image data by a decoding method corresponding to a predetermined encoding method such as MPEG2 or MPEG4, and generates the reproduced moving image data on the display 32 via the display control unit 255. Thus, for example, moving image data included in a moving image file linked from a web page is displayed.

  At the same time, the audio codec 259 converts the audio data into an analog audio signal, and then supplies the analog audio signal to the speaker 217. Thus, for example, the audio data included in the moving image file linked from the web page is reproduced. .

  In this case as well, as in the case of e-mail, the mobile phone 31 can record data linked from a web page or the like on the memory stick 223 via the recording / playback unit 224 by a user operation.

  Next, the operation of the DVR 12 of FIG. 5 will be described with reference to the flowcharts of FIGS.

  First, an EPG acquisition process in which the DVR 12 acquires EPG data will be described with reference to the flowchart of FIG.

  In step S1, the tuner unit 101 receives a broadcast signal from the antenna 11 (FIG. 1), supplies a packet of a predetermined channel (frequency band) to the demultiplexer 102 according to the control of the CPU 108, and performs step S2. Proceed to

  In step S2, the demultiplexer 102 selects a packet in which EPG data is arranged from the packets supplied from the tuner unit 101 under the control of the CPU 108, and supplies the selected packet to the CPU 108 via the bus. Proceed to

  In step S <b> 3, the CPU 108 extracts EPG data from the packet from the demultiplexer 108 and supplies it to the HD drive 116. The HD drive 116 records (stores) the EPG data from the CPU 108 in the HD 117.

  As described above, EPG data is recorded on the HD 117. Note that old data in the EPG data recorded in the HD 117, that is, EPG data of the previous day's program, for example, is appropriately deleted by the CPU 108 controlling the HD drive 116.

  When EPG data is recorded on the HD 117, for example, when the operation panel 109 or a remote controller (hereinafter referred to as the operation panel 109 or the like as appropriate) is operated to display the EPG, the CPU 108 causes the HD drive 116 to be By controlling, the EPG data for the time zone or channel corresponding to the operation of the operation panel 109 or the like is read from the HD 117, and the EPG screen 41 (FIG. 2) having a predetermined format is created using the EPG data. Further, the CPU 108 supplies the EPG screen 41 to the OSD unit 103A built in the video decoder 103 via the bus. The OSD unit 103A superimposes the EPG screen 41 from the CPU 108 on the decoding result of the video decoder 103 and outputs it from the video output terminal 105 as necessary. As a result, the EPG screen 41 is displayed on the TV receiver 13 (FIG. 1) connected to the video output terminal 105 as shown in FIG.

  For example, the user A staying at the user A's home can make a recording reservation for a desired program while viewing the EPG screen 41. That is, when the user A operates the operation panel 109 or the like so as to designate a desired program on the EPG screen 41 and reserve the recording, the CPU 108 controls the HD drive 116 to record on the HD 117. The program information of the reservation target program (channel, broadcast date, broadcast start time, broadcast end time, title, description of the contents of the program) is read out from the EPG data, and the reservation target program is reserved using the program information A setting screen for setting program recording information necessary for recording is created.

  Then, the CPU 108 supplies the setting screen to the TV receiver 103 via the bus, the OSD unit 103A, and the video output terminal 105, whereby the setting screen is displayed on the TV receiver 103.

  Here, the setting screen is configured similarly to the reservation screen 53 described with reference to FIG. 3, for example. Therefore, the setting screen has a “date” field, a “time” field, a “channel” field, a “recording mode” field, an “extension” field, and a “protect” field. ”,“ Channel ”,“ Recording mode ”,“ Extension ”, and“ Protect ”fields are set with the default information described in the reservation screen 53.

  When the user A wishes to make a recording reservation for the reservation target program with the content displayed on the setting screen, the user A operates the operation panel 109 or the like so as to confirm the recording reservation. When the operation panel 109 or the like is operated to confirm the recording reservation, the DVR 12 uses the information set (displayed) on the setting screen at that time as the program recording information necessary for the reserved recording of the reservation target program. Reservation processing is performed.

  FIG. 8 is a flowchart for explaining the reservation process performed by the DVR 12.

  In step S <b> 11, the CPU 108 determines whether or not the reservation target program overlaps with the recording of another program in the program recording information of the reservation target program and the reservation list stored (recorded) in the HD 117. Refer to the program recording information.

  That is, the reservation list is a list of programs for which recording reservation has been confirmed, and the program recording information of the program is registered. In step S11, the broadcast time zone of the reservation target program is recorded in the reservation list. It is determined whether the information does not overlap with the broadcast time zone of the already registered program.

  In step S11, when it is determined that the broadcast time zone of the program to be reserved overlaps with the broadcast time zone of the program whose program recording information is already registered in the reservation list, two programs that partially overlap the broadcast time zone are selected. Since recording cannot be performed simultaneously, the process proceeds to step S12, and the CPU 108 controls the OSD unit 103A to cause the TV receiver 13 to display a duplicate message indicating that the broadcast time zones overlap, and ends the reservation process. . Therefore, in this case, recording reservation of the reservation target program is not performed.

  On the other hand, if it is determined in step S11 that the broadcast time zone of the reservation target program does not overlap with the broadcast time zone of the program whose program recording information is already registered in the reservation list, the process proceeds to step S13, and the CPU 108 Recording reservation processing (recording reservation processing) for registering (adding) the program recording information of the reservation target program in the reservation list recorded in the recording list, thereby completing the recording reservation of the reservation target program and performing the reservation processing. finish.

  As described above, the program recording information of the program to be reserved recording is registered in the reservation list. Therefore, it can be said that the reservation list is reservation status information related to the recording reservation status of the program.

  Here, in the embodiment of FIG. 5, since the DVR 12 has only one tuner unit 101, it is not possible to simultaneously record two programs with overlapping broadcast time zones, but the DVR 12 has a plurality of tuner units. In this case, it is possible to simultaneously record the number of programs in the tuner unit.

  In the reservation process of FIG. 8, if the broadcast time zone of the reservation target program overlaps with the broadcast time zone of the program whose program recording information is already registered in the reservation list, the recording reservation of the reservation target program is performed. Other, for example, recording reservations for programs whose program recording information is already registered in the reservation list, for which the reservation target program and the broadcast time zone overlap (hereinafter referred to as overlapping programs as appropriate) Can be canceled and the recording reservation of the reservation target program can be made, that is, the program recording information of the duplicate program can be deleted and the program recording information of the reservation target program can be additionally registered in the reservation list. Whether or not to cancel the recording reservation for the duplicate program and make the recording reservation for the reservation target program is preferably performed after asking the user for confirmation.

  Next, the CPU 108 of the DVR 12 monitors the current time (date and time), and when the current date and time becomes the broadcast start time (immediately before) of the program whose program recording information is registered in the HD 117 reservation list, the DVR 12 Then, a reservation recording process (reservation recording process) for performing reservation recording of the program is performed.

  That is, FIG. 9 is a flowchart for explaining the reserved recording process performed by the DVR 12.

  In the DVR 12, when the current time becomes the broadcast start time in the program recording information registered in the reservation list, in step S21, the program specified by the program recording information is recorded as a recording target program.

  That is, in step S21, the CPU 108 refers to the channel or the like in the program recording information of the recording target program registered in the reservation list so that the tuner unit 101 and the demultiplexer 102 can obtain the packet of the recording target program. Thus, the demultiplexer 102 outputs the packet of the recording target program on the bus. The packet of the recording target program output on the bus is supplied to the HD drive 116 and recorded in the built-in HD 117. As described above, the recording target program is recorded.

  Then, when the current time is the broadcast end time in the program recording information of the recording target program, the CPU 108 controls the tuner unit 101, the demultiplexer 102, and the HD drive 116 to end the recording process. The process proceeds from step S21 to S22.

  Here, recording is performed from the broadcast start time to the broadcast end time of the recording target program. However, the recording target program starts to be recorded from a time that is a first time before the broadcast start time. It is possible to end the recording at a time that is a second time after the broadcast end time. The first and second times may be fixed default times or may be settable by the user.

  In step S22, the CPU 108 registers the program recording information of the recording target program in the recorded list stored (recorded) in the HD 117.

  That is, the recorded list is a list of programs (recorded programs) in which recording is completed and data (packets) are recorded in the HD 117, and the program recording information of the programs is registered. Then, the program recording information of the recording target program that has been recorded (the program that was the recording target program (recorded program)) is registered in the recorded list.

  Thereafter, the process proceeds from step S22 to S23, and the CPU 108 deletes the program recording information of the recording target program that has been recorded from the reservation list stored in the HD 117, and ends the reserved recording process.

  In the DVR 12, the reservation list and the recorded list stored in the HD 117 are output to the TV receiver 13 via the OSD unit 103 </ b> A and the video output terminal 105 in response to the operation of the operation panel 109, for example. Can be displayed.

  The user A can cancel the recording reservation, erase the recorded program (data), and the like with reference to the reservation list and the recorded list displayed on the TV receiver 13.

  That is, when the user A selects program recording information of a program to cancel the recording reservation in the reservation list displayed on the TV receiver 13, and operates the operation panel 109 or the like so as to cancel the recording reservation, The CPU 108 deletes the corresponding program recording information from the reservation list stored in the HD 117. Further, when the user A selects program recording information whose contents are to be changed in the reservation list displayed on the TV receiver 13 and operates the operation panel 109 or the like so as to change the contents, the CPU 108 In response to the operation, the program recording information in the reservation list stored in the HD 117 is changed. Specifically, the channel, broadcast start time, broadcast end time, recording mode, protect information, etc. in the program recording information are changed.

  Further, the operation panel 109 or the like is selected so that the user A selects program recording information of a program to be deleted (recorded program) in the recorded list displayed on the TV receiver 13 and deletes the program. Is operated, the CPU 108 deletes the corresponding program recording information from the recorded list stored in the HD 117 and also deletes the corresponding program (data) from the HD 117.

  As described above, the reservation list and the recorded list can be edited by the user A operating the operation panel 109 or the like.

  Next, a web server program is installed in the HD 117 of the DVR 12, and the DVR 12 functions as a web server when the CPU 108 executes the web server program.

  FIG. 10 is a flowchart for explaining web server processing performed by the DVR 12 as a web server.

  For example, when the user A away from home operates the mobile phone 31 so as to access the DVR 12, the mobile phone 31 sends a request for a predetermined menu screen as a web page to the base station 22 (FIG. 1), the network 21. And to the DVR 12 via the router 14. In the DVR 12, the communication I / F 107 receives a menu screen request from the mobile phone 31 and supplies it to the CPU 108.

  When a request for a menu screen is supplied from the communication I / F 107, the CPU 108 causes the communication I / F 107 to transmit a predetermined menu screen that is a web page in step S31. Thereby, the menu screen is transmitted from the communication I / F 107 to the mobile phone 31 via the router 14 (FIG. 1), the network 21, and the base station 22. In the mobile phone 31, the menu screen is received and displayed on the display 32.

  Here, for example, a button for requesting an EPG, a button for requesting a reservation list, a button for requesting a recorded list (or display of icons, hyperlinks, etc.) are provided on the menu screen.

  The CPU 108 transmits the menu screen to the communication I / F 107 in step S31, and then proceeds to step S32 to determine whether or not there is any information request from the mobile phone 31.

  In step S32, when it is determined that there is a request for some information from the mobile phone 31, that is, the user A operates the mobile phone 31 to request some information (for example, EPG, reservation list, recording) When the information request is transmitted from the mobile phone 31 and received by the communication I / F 107, the process proceeds to step S33, and the CPU 107 displays the requested information. The communication I / F 107 is transmitted, and the process returns to step S32.

  That is, when the request for information from the mobile phone 31 requests the program guide list screen 51 and the program details screen 52 described with reference to FIG. 3, the CPU 108 uses the web page from the EPG data recorded in the HD 117. The program guide list screen 51 and the program detail screen 52 are created and transmitted from the communication I / F 107 to the mobile phone 31. The mobile phone 31 receives the program guide list screen 51 and the program details screen 52 transmitted from the communication I / F 107 and displays them on the display 32.

  When the request for information from the mobile phone 31 is a request for a reservation list or recorded list, the CPU 108 selects the reservation list or recorded list from the reservation list or recorded list stored in the HD 117. A reservation list screen or a recorded list screen, which is a web page, is created and transmitted from the communication I / F 107 to the mobile phone 31. In the mobile phone 31, the reservation list screen or the recorded list screen transmitted from the communication I / F 107 is received and displayed on the display 32.

  Further, when the request for information from the mobile phone 31 is a request for a menu screen, the CPU 108 causes the communication I / F 107 to transmit the menu screen as in step S31. The menu screen is received by the mobile phone 31 and displayed on the display 32.

  Here, in the mobile phone 31, when the reservation list screen or the recorded list screen is displayed on the display 32, the user A moves the mobile phone 31 to edit the reservation list screen or the recorded list screen. By operating the operation unit 33, the reservation list or the recorded list stored in the HD 117 of the DVR 12 can be edited in the same manner as when the operation panel 109 or the like of the DVR 12 is operated. The editing of the reservation list and the recorded list by operating the operation unit 33 of the mobile phone 31 will be described later.

  On the other hand, if it is determined in step S32 that there is no request for information from the mobile phone 31, the process proceeds to step S34, and the CPU 108 determines whether or not there is a reservation request from the mobile phone 31 to request recording reservation of a program.

  That is, as described with reference to FIG. 3, in the mobile phone 31, when the reservation screen 53 is displayed on the display 32, the user A desires to make a recording reservation for the reservation target program with the contents of the reservation screen 53. When the operation unit 33 of the mobile phone 31 is operated so as to confirm the recording reservation, the mobile phone 31 uses the information set (displayed) on the reservation screen 53 for reservation recording of the reservation target program. The program recording information is transmitted to the DVR 12 together with a reservation request which is a request for recording reservation. In step S34, it is determined whether or not there is such a reservation request.

  In step S34, when it is determined that there is a reservation request from the mobile phone 31, that is, a reservation request and program recording information are transmitted from the mobile phone 31, received by the communication I / F 107, and further, the reservation request and program When the recording information is supplied to the CPU 108, the process proceeds to step S35.

  In step S35, the CPU 108 determines whether or not a program for which a recording reservation is requested by a reservation request from the mobile phone 31 (also referred to as a reservation target program as appropriate) overlaps with recording of other programs. The determination is made in the same manner as in step S11 of FIG.

  That is, in step S35, the CPU 108 recognizes the broadcast time zone (from the recording start time to the recording end time) (including the date) of the reservation target program based on the program recording information transmitted together with the reservation request from the mobile phone 31. Then, it is determined whether or not the broadcast time zone of the reservation target program overlaps with the broadcast time zone of the program whose program recording information is already registered in the reservation list stored in the HD 117.

  In step S35, when it is determined that the broadcast time zone of the program to be reserved overlaps with the broadcast time zone of the program whose program recording information is already registered in the reservation list, two programs that partially overlap the broadcast time zone are selected. Since recording cannot be performed at the same time, the process proceeds to step S36, and the CPU 108 causes the communication I / F 107 to transmit to the mobile phone 31 duplicate information that is a message indicating that the broadcast time zones overlap, and returns to step S32.

  Duplicate information transmitted from the communication I / F 107 is received by the mobile phone 31 and displayed on the display 32. Thereby, the user A who possesses the mobile phone 31 has to give up recording of the reservation target program, or from the reservation list, the program recording information of the program whose broadcast time zone overlaps with the reservation target program. If it is not deleted (the recording reservation of the program is not canceled), it can be recognized that the recording reservation of the reservation target program cannot be performed.

  If it is determined in step S35 that the broadcast time zone of the reservation target program does not overlap with the broadcast time zone of the program whose program recording information is already registered in the reservation list, the process proceeds to step S37, and the CPU 108 Perform recording reservation processing for the target program. That is, in step S37, as in step S13 of FIG. 8, the CPU 108 registers the program recording information of the reservation target program in the reservation list stored in the HD 117, and proceeds to step S38.

  In step S38, the CPU 108 transmits reservation completion information, which is a message indicating that the recording reservation of the reservation target program has been completed, from the communication I / F 107 to the mobile phone 31, and returns to step S32.

  The reservation completion information transmitted from the communication I / F 107 is received by the mobile phone 31 and displayed on the display 32. Thereby, the user A carrying the mobile phone 31 can recognize that the recording reservation of the reservation target program has been completed.

  On the other hand, if it is determined in step S34 that there is no reservation request from the mobile phone 31, the process proceeds to step S39, and the CPU 108 determines whether or not there has been an edit request from the mobile phone 31 to edit the reservation list. judge.

  That is, when the reservation list screen is displayed on the display 32 in the mobile phone 31, when the user A operates the operation unit 33 of the mobile phone 31 to edit the reservation list screen, the mobile phone 31. Transmits an edit request for requesting editing of the reservation list to the DVR 12 in accordance with the operation. In step S39, it is determined whether or not there is such an editing request.

  If it is determined in step S39 that there is an editing request from the mobile phone 31, that is, if an editing request is transmitted from the mobile phone 31, received by the communication I / F 107, and further supplied to the CPU 108, step S40 Proceed to

  In step S40, the CPU 108 edits the reservation list stored in the HD 117 in response to the editing request from the mobile phone 31, and proceeds to step S41. In step S41, the CPU 108 creates a reservation list screen that is a web page of the reservation list from the edited reservation list, transmits the reservation list screen to the mobile phone 31 from the communication I / F 107, and returns to step S32. The cellular phone 31 receives the reservation list screen transmitted from the communication I / F 107, whereby the display 32 displays a reservation list screen corresponding to the edited reservation list.

  Although the case where the reservation list is edited has been described here, the recorded list can also be edited.

  That is, when the recorded list screen is displayed on the display 32 in the mobile phone 31, when the user A operates the operation unit 33 of the mobile phone 31 so as to edit the recorded list screen, the mobile phone 31 The telephone 31 transmits to the DVR 12 an edit request for requesting editing of the recorded list according to the operation.

  In the DVR 12, the recorded list editing request from the mobile phone 31 is received by the communication I / F 107. In this case, the CPU 108 edits the recorded list stored in the HD 117 in response to an editing request from the mobile phone 31, and the recorded list screen which is a web page of the recorded list from the edited recorded list. And is transmitted from the communication I / F 107 to the mobile phone 31. The cellular phone 31 receives the recorded list screen transmitted from the communication I / F 107, whereby the recorded list screen corresponding to the edited recorded list is displayed on the display 32. If the recorded list edit request is a request to delete a program, the CPU 108 deletes the program recording information corresponding to the program from the recorded list, and also receives the corresponding program ( Data).

  On the other hand, if it is determined in step S39 that there is no editing request, the process proceeds to step S42, and the CPU 108 determines whether or not the mobile phone 31 has received an end request for requesting the end of communication.

  That is, when the user A operates the operation unit 33 of the mobile phone 31 so as to end the communication with the DVR 12 in the mobile phone 31, the mobile phone 31 transmits an end request to the DVR 12 in accordance with the operation. To do. In step S42, it is determined whether or not there is such an end request.

  If it is determined in step S42 that there is no termination request from the mobile phone 31, the process returns to step S32, and the same processing is repeated thereafter.

  In step S42, when it is determined that there is a termination request from the mobile phone 31, that is, a termination request is transmitted from the cellular phone 31, and the termination request is received by the communication I / F 107 and supplied to the CPU 108. In the case of DVR 12 (CPU 108), the web server process ends.

  Next, a web browser (client) program is installed in the EEPROM 204 of the mobile phone 31 (FIG. 6), and the CPU 201 executes the web browser program, so that the mobile phone 31 functions as a web browser. Function.

  FIG. 11 is a flowchart for explaining web browser processing performed by the mobile phone 31 as a web browser.

  For example, when the user A away from home operates the operation unit 33 of the mobile phone 31 so as to access the DVR 12, the CPU 201 starts executing the program of the web browser. A request for a menu screen is transmitted to the DVR 12 via the unit 262, the antenna 214, the base station 22 (FIG. 1), the network 21, and the router 14.

  When the DVR 12 receives the menu screen request from the mobile phone 31, it transmits the menu screen to the mobile phone 31, as described in step S31 of FIG. In step S61, the modem circuit unit 258 receives the menu screen via the antenna 214, supplies it to the CPU 201, and proceeds to step S62. In step S62, the CPU 201 supplies the menu screen from the DVR 12 to the display control unit 255, thereby causing the display 32 to display the menu screen, and the process proceeds to step S63.

  Here, as described in FIG. 10, the menu screen is provided with, for example, an EPG, a reservation list, a hyperlink to a recorded list, and the like.

  In step S63, the CPU 201 determines whether the user A has operated the operation unit 33 so as to request some information.

  In step S63, when it is determined that the operation unit 33 has been operated so as to request information, that is, for example, when the user A operates the operation unit 33, the EPG, the reservation list, and the recorded list are displayed. In step S64, the CPU 201 causes the modulation / demodulation circuit unit 258 and the transmission / reception unit 262 to transmit a request for information corresponding to the operation of the operation unit 33. Here, the request for information corresponding to the operation of the operation unit 33 includes, for example, a URL (Uniform Resource Locator) specifying the information.

  When the DVR 12 receives a request for information from the mobile phone 31, as described in step S33 of FIG. 10, the information corresponding to the request for information, that is, the program guide list screen 51, the program details screen 52, the reservation list Since the web page such as the screen, the recorded list screen, the menu screen is transmitted, the transmission / reception circuit unit 262 and the modem circuit 258 of the mobile phone 31 receive the information from the DVR 12 and supply it to the CPU 201 in step S65. Then, the process proceeds to step S66. In step S66, the CPU 201 supplies the information from the DVR 12 to the display 32 via the display control unit 255, and returns to step S63. Thereby, on the display 32, a program guide list screen 51, a program details screen 52, a reservation list screen, a recorded list screen, or a menu screen is displayed instead of the screen so far.

  If it is determined in step S63 that the operation unit 33 has not been operated so as to request information, the process proceeds to step S67, and the CPU 201 performs an operation so that the user A requests program recording reservation. It is determined whether the unit 33 has been operated.

  That is, in step S67, as described with reference to FIG. 3, when the reservation screen 53 of FIG. 3 is displayed on the display 32 in the mobile phone 31, the user A can make a reservation with the contents of the reservation screen 43. It is determined whether or not the operation unit 33 of the mobile phone 31 has been operated so that the recording reservation of the program is desired and the recording reservation is confirmed.

  In step S67, when it is determined that the operation unit 33 has been operated so as to request a recording reservation of a program, that is, the operation unit 33 so as to confirm the recording reservation of the reservation target program with the content of the reservation screen 43. Is operated, the CPU 201 transmits / receives information set (displayed) on the reservation screen 53 as program recording information necessary for reservation recording of the reservation target program together with the reservation request via the modulation / demodulation circuit unit 258. The voltage is supplied to the circuit unit 262, and the process proceeds to step S68. In step S68, the transmission / reception circuit unit 262 transmits the reservation request and program recording information from the CPU 201 to the DVR 12 via the antenna 214.

  When the DVR 12 receives a reservation request from the mobile phone 31, it transmits duplicate information or reservation completion information as a message, as described in steps S36 and S38 of FIG. From step S68 to step S69, the duplication information or the reservation completion information from the DVR 12 is received via the antenna 214, and the modulation / demodulation circuit unit 258 is passed through. To the CPU 201, and the process proceeds to step S70.

  In step S70, the CPU 201 supplies the duplication information or reservation completion information from the DVR 12 to the display 32 via the display control unit 255, thereby causing the display 32 to display the duplication information or reservation completion information. Return to S63.

  As described above, since the overlap information and the reservation completion information are displayed on the display 32, the user A has a program whose broadcast time zone overlaps with the reservation target program, or has made a recording reservation for the reservation target program. You can recognize that it has been completed.

  On the other hand, if it is determined in step S67 that the operation unit 33 has not been operated so as to request the recording reservation of the program, the process proceeds to step S71, and the CPU 201 requests the user A to edit the reservation list. Next, it is determined whether or not the operation unit 33 has been operated.

  That is, in step S71, when the reservation list screen is displayed on the display 32 in the mobile phone 31, has the user A operated the operation unit 33 of the mobile phone 31 to edit the reservation list screen? Whether it is determined.

  If it is determined in step S71 that the operation unit 33 has been operated so as to edit the reservation list screen, the process proceeds to step S72, and the CPU 201 modifies / demodulates an edit request for editing the reservation list according to the operation. The signal is supplied to the transmission / reception circuit unit 262 via the circuit unit 268, thereby causing the editing request to be transmitted to the DVR 12 via the antenna 214.

  When the DVR 12 receives an edit request for requesting edit of the reservation list from the mobile phone 31, the DVR 12 stores the reservation list stored in the HD 117 in response to the edit request as described in steps S40 and S41 of FIG. Since the edited reservation list screen is created and transmitted from the edited reservation list, the transmission / reception circuit unit 262 waits for the edited reservation list screen to be transmitted from the DVR 12, and step S 72. The process proceeds to S73, receives the edited reservation list screen from the DVR 12 via the antenna 214, supplies it to the CPU 201 via the modulation / demodulation circuit unit 258, and proceeds to step S74.

  In step S74, the CPU 201 supplies the edited reservation list screen from the DVR 12 to the display 32 via the display control unit 255, thereby causing the display 32 to display the edited reservation list screen. Return to S63.

  Note that the mobile phone 31 can edit the recorded list as well as the reservation list of the DVR 12.

  That is, when the recorded list screen is displayed on the display 32 in the mobile phone 31, when the user A operates the operation unit 33 of the mobile phone 31 so as to edit the recorded list screen, the mobile phone 31 The telephone 31 transmits to the DVR 12 an edit request for requesting editing of the recorded list according to the operation.

  When the DVR 12 receives a request for editing a recorded list from the mobile phone 31, the DVR 12 edits the recorded list stored in the HD 117 in response to the editing request as described in FIG. A recorded list screen is created from the completed list and transmitted to the mobile phone 31. The mobile phone 31 receives the edited recorded list screen from the DVR 12 and displays it on the display 32.

  On the other hand, if it is determined in step S71 that the operation unit 33 has not been operated so as to edit the reservation list screen, the process proceeds to step S75, and the CPU 201 causes the user A to end communication with the DVR 12. Then, it is determined whether or not the operation unit 33 has been operated.

  If it is determined in step S75 that the operation unit 33 has not been operated so as to end communication with the DVR 12, the process returns to step S63, and the same processing is repeated thereafter.

  Further, when it is determined in step S75 that the operation unit 33 has been operated so as to end the communication with the DVR 12, that is, for example, when the user operates the operation unit 33 so as to end the web browser. In step S76, the CPU 201 supplies a termination request for requesting termination of communication to the transmission / reception circuit unit 262 via the modulation / demodulation circuit unit 268, whereby the termination request is transmitted to the DVR 12 via the antenna 214. Send it and finish the web browser process.

  As described above, the DVR 12 stores EPG data, a reservation list as reservation status information related to the program recording reservation status, and further stores a recorded list related to a recorded program, and communicates with the mobile phone 31. In response to a request from the mobile phone 31, a program guide list screen 51 (FIG. 3) created from EPG data, a reservation list screen created from a reservation list, and a recorded list screen created from a recorded list are transmitted. On the other hand, the mobile phone 31 transmits a request for the program guide list screen 51, the reservation list screen, and the recorded list screen in response to a user operation by communicating with the DVR 12, and in response to the request, Since the program guide list screen 51, the reservation list screen, and the recorded list screen transmitted from the DVR 12 are received and presented, the information that the DVR 12 has It can be effectively utilized, thereby, it is possible to provide such a highly convenient DVR 12.

  That is, the mobile phone 31 presents the program guide list screen 51 created from the EPG data recorded in the DVR 12 to the user A by communicating with the DVR 12, so that the mobile phone 31 uses the EPG data recorded in the DVR 12. The program guide list screen 51 as the latest EPG can be browsed. Furthermore, the user A does not need to access the EPG server in order to view the EPG from outside, and therefore does not need to install the EPG server.

  Further, since the user A can browse the reservation list screen and the recorded list screen as the state (presence) of the DVR 12 from the outside, for example, for the program that has already been reserved for recording, the user A can make a recording reservation again. It is possible to prevent such a useless recording reservation.

  Further, the mobile phone 31 transmits a reservation request for requesting recording recording of a program or an edit request for requesting editing of a reservation list or the like according to the operation of the user A, and the DVR 12 receives a reservation request from the mobile phone 31. In response to the reservation request or the edit request, the recording reservation process or the reservation list is edited, so that the user A operates the DVR 12 directly from the outside. And the convenience of the DVR 12 can be improved.

  Next, in the case described above, for the sake of simplicity, it is assumed that the mobile phone 31 recognizes in advance the NAT passing method of the router 14. It is not preferable to recognize the method in advance from the viewpoint of security. Further, the IP address (global IP address) on the WAN side of the router 14 may be variable instead of being fixed.

  FIG. 12 shows a configuration example of another embodiment of the recording reservation system to which the present invention is applied. In the figure, portions corresponding to those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted below as appropriate. That is, the recording reservation system in FIG. 12 is configured in the same manner as in FIG. 1 except that the matching server 301 is newly connected to the network 21.

  The matching server 301 includes a proxy server 302 and an XMPP (eXtensible Messaging and Presence Protocol) server 303.

  The proxy server 302 performs access control to the XMPP server 303 via the network 21. The XMPP server 303 provides a service for enabling the mobile phone 31 and the DVR 12 to exchange messages (data) directly via the network 21 that is the Internet, by using XMPP.

  Next, operations of the DVR 12, the router 14, the mobile phone 31, and the matching server 301 in FIG. 12 will be described with reference to FIG.

  For example, after purchasing the DVR 12, the user A operates the operation panel 109 (FIG. 5) or the like to register an ID (Identification) and a password in the matching server 301. That is, for example, a membership card in which an ID and a password are written is bundled with the DVR 12, and the user A operates the operation panel 109 and the like to change the ID and password written in the membership card to the DVR 12. To enter.

  The DVR 12 stores (records) the ID and password input by the user A operating the operation panel 109 or the like in, for example, the EEPROM 113 (or HD 117), and further, from the communication I / F 107 in step S101, the router 14 and the network 21 to the matching server 301. In the matching server 301, in step S121, the XMPP server 303 receives and stores the ID and password transmitted from the DVR 12, and thereby the ID and password of the DVR 12 are registered.

  Thereafter, in step S102, the DVR 12 logs in (logon) by transmitting the ID and password stored in the EEPROM 113 together with the login request from the communication I / F 107 to the matching server 301 via the router 14 and the network 21. Further, the IP address (global IP address) assigned to the WAN side of the router 14 is notified by transmitting it to the matching server 301.

  In step S122, the XMPP server 303 of the matching server 301 receives the login request from the DVR 12 and the ID and password. If the ID and password match the ID and password of the DVR 12 registered in step S121 ( If the ID and password registered in the XMPP server 303 match, the login of the DVR 12 is permitted. Furthermore, in step S122, the XMPP server 303 of the matching server 301 receives the IP address of the router 14 transmitted from the DVR 12 after the login is permitted, and stores it in association with the ID and password of the DVR 12.

  For example, when the state of the DVR 12 or the router 14 changes, the DVR 12 logs off from the matching server 301 and then logs in again to notify the IP address of the router 14. Here, when the state of the DVR 12 changes, for example, when the DVR 12 has a function as a game machine, the use as a game machine may be terminated. Furthermore, as a case where the state of the DVR 12 has changed, for example, when the DVR 12 can reproduce the DVD as the disc 115, the reproduction of the DVD may be terminated. Moreover, as a case where the state of the router 14 changes, for example, the IP address assigned to the router 14 may change.

  Thereafter, when the user A who possesses the mobile phone 31 tries to access the DVR 12 from an outside location or the like, the user A operates the operation unit 33 of the mobile phone 31 to operate the base station 22 and the network 21. To access the matching server 301, and further log in by entering the ID and password.

  That is, the user A operates the operation unit 33 of the mobile phone 31 to input the same ID and password registered in the matching server 301 in step S101 to the mobile phone 31. In this case, the mobile phone 31 transmits the ID and password input by the user A operating the operation unit 33 to the matching server 301 via the base station 22 and the network 21 together with the login request in step S131. To login.

  In step S123, the XMPP server 303 of the matching server 301 receives the login request from the mobile phone 31, and the ID and password. If the ID and password match the ID and password registered in step S121 ( If the ID and password registered in the XMPP server 303 match, the login of the mobile phone 31 is permitted.

  Thereafter, the XMPP server 303 of the matching server 301 connects the mobile phone 13 to the IP address stored in association with the ID and password from the mobile phone 31 permitted to log in in step S123, that is, to the router 14. Send a port confirmation message requesting confirmation of the port used for communication.

  In step S <b> 111, the router 14 receives the port confirmation message from the XMPP server 303 and transmits it to the DVR 12. In step S103, the DVR 12 receives the port confirmation message from the router 14.

  When the DVR 12 receives the port confirmation message, in step S104, the DVR 12 exchanges necessary information with the router 14, and dynamically uses the UPnP (Universal Plug and Play) port to be used for communication with the mobile phone 13. Go to step S105. In step S105, the DVR 12 uses the XMPP server 303 of the matching server 301 to indicate the socket information indicating the socket for accessing the DVR 12 (menu screen thereof) such as the port number specifying the port opened in step S104 and the IP address. Notify by sending to.

  In step S125, the XMPP server 303 of the matching server 301 receives the socket information from the DVR 12, proceeds to step S126, and notifies the socket information by transmitting the socket information to the mobile phone 31.

  In step S132, the cellular phone 31 receives the socket information from the XMPP server 303, proceeds to step S133, and accesses the DVR 12 via the router 14 based on the socket information received in step S132. That is, the mobile phone 31 directly communicates (Direct Access) with the DVR 12 without using a server that relays communication between the mobile phone 31 and the DVR 12 such as the matching server 301 based on the socket information. be able to.

  For example, the mobile phone 31 transmits a menu screen request to the DVR 12 in step S133, and the DVR 12 transmits a menu screen to the mobile phone 31 in response to the request in step S106.

  In addition, as described with reference to FIGS. 10 and 11, the mobile phone 31 and the DVR 12 exchange a program table list screen 51 (FIG. 3) as an EPG, a reservation request, reserved program information, reservation completion information, and the like. Is done.

  As described above, the mobile phone 31 acquires the socket information of the DVR 12 via the XMPP server 303 and accesses the DVR 12 from the mobile phone 31 based on the socket information. Can be ensured, and even if the IP address on the WAN side of the router 14 is variable, the mobile phone 31 can access the DVR 12.

  Here, as described above, the matching server 301 (the XMPP server 303) provides a relay service for the mobile phone 31 to acquire (receive) socket information. Can be charged. This charging may be performed in the matching server 301 or may be performed together with the charge of the call charge in the carrier company of the mobile phone 31 possessed by the user A.

  In this embodiment, a program composed of video data and audio data is adopted as the program. However, the program is a program of only audio data, a computer program or other data program (data broadcasting program). It may be.

  In the present embodiment, the EPG data (program table list screen 51) is acquired (received) from the DVR 12 in the mobile phone 31, but in the mobile phone 31, digital broadcasting broadcasted by the broadcast station 1 is received. By directly receiving a wave, it is possible to acquire EPG data included in the digital broadcast wave.

  Furthermore, in this embodiment, the DVR 12 is accessed from the mobile phone 31 located outside the user A's home via the base station 22, the network 21, and the router 21, but the user A is the user A When the user is at home, for example, the DVR 12 can be accessed from the mobile phone 31 via the router 14 by a so-called wireless LAN.

  In addition, the communication device that communicates with the DVR 12 is not limited to the mobile phone 31, and for example, a PDA (Personal Digital Assistance) having a communication function, a portable personal computer (so-called notebook personal computer, etc.) It may be a desktop personal computer installed in advance.

  Further, although the DVR 12 receives and records digital broadcast waves, the DVR 12 may receive and record analog broadcast waves.

  In the DVR 12, the program is recorded on the HD 117 or the disk 115, but the recording medium for recording the program may be, for example, a semiconductor memory or a tape-shaped recording medium.

  Furthermore, in this embodiment, the reservation list and the recorded list are displayed separately from the EPG screen 41 (FIG. 2) and the program guide list screen 51 (FIG. 3) which are EPG screens. Information on the list and the recorded list can be displayed superimposed on (combined with) the EPG screen 41 and the program guide list screen 51. That is, on the EPG screen 41 and the program guide list screen 51, for example, a mark indicating a program reserved for recording or a mark indicating a recorded program can be displayed. In this case, the user can recognize a program reserved for recording or a recorded program simply by looking at the EPG screen 41 or the program guide list screen 51.

  Further, in this specification, the processing steps for describing a program for causing a computer (processor) to perform various processes do not necessarily have to be processed in time series according to the order described in the flowcharts. It includes processing executed individually (for example, parallel processing or object processing).

  Further, the program may be processed by a single computer, or may be processed in a distributed manner by a plurality of computers.

  Furthermore, the processing performed by the CPU 108 or 201 executing the program can be performed by dedicated hardware.
