Description

  The present invention relates to a broadcast receiving apparatus, and more particularly to a broadcast receiving apparatus that transmits, receives, and records information, such as a software download service by digital broadcasting.

  In recent years, digitalization of broadcasting has progressed. With the advent of multimedia services due to the digitization of broadcasting, broadcast receiving devices have processing by software. This means that by updating / adding software in the broadcast receiving apparatus, it is possible to realize a more advanced service and broadcast receiving apparatus without adding hardware or replacing the hardware. This makes it possible to perform services such as updating the function of each broadcast receiving apparatus and data common to all receiving apparatuses, and adding a new service broadcast receiving apparatus program.

  A software download service enables the software in such a broadcast receiving apparatus to be updated / added using a transmission means such as a broadcast wave or the Internet.

  The software download service is positioned as one of multimedia services, and a service ID is assigned to configure a composition channel. In addition, a DSM-CC data carousel that is a multimedia transmission protocol is used as a transmission protocol. By adopting the DSM-CC standard of MPEG, which is a global standard system, consistency is achieved in the communication and computer fields, and also in other media such as the ground and cables.

  Further, in the above method, flexible selectivity is ensured for specifying a download form and a download update destination based on DSM-CC. The download format is a selection type based on the viewer's selection, a forced type that is forcibly updated / added by the broadcaster, etc., and it does not affect program viewing when the desired data arrives during normal program viewing. It is possible to select an automatic type for downloading, a notification type for performing a startup operation of the receiving device based on notification information of the download schedule when the program is not viewed, and the like. As update destinations, for each model, for each group that is an aggregate of models, and for all receivers can be specified. Furthermore, it is possible to flexibly select update modules such as update of all received programs and update in designated module units.

  SDTT (Software Download Trigger Table) is used for notification of the download schedule. The contents notified by the SDTT include schedule information, content information, identification information of the target receiving device, version, importance of download content, content properties, and content description.

  The schedule information is information for designating the broadcast date and time and the broadcast station. The content information is information for specifying a program or a common data file. The identification information of the target reception device is identification information of the reception device configured by manufacturer identification, model identification, group identification, and the like of the broadcast reception device. The version is version information of content to be downloaded. The importance of the download content is information indicating whether it is forced download or selective download. The nature of the content is information indicating the distinction between addition / overwriting and the operation of the receiving apparatus after updating (necessity of restart or the like). The description of the content is information that helps the receiving device (the user) determine the content of the content at the time of selective download.

  For a more detailed operation example of the SDTT, refer to the standard “program arrangement information used for digital broadcasting” in the Japan Radio Industry Association (commonly known as ARIB).

  Currently, a version upgrade service by rewriting the firmware of a broadcast receiving apparatus is provided as a software download service. The broadcast receiving apparatus presents a selection screen as shown in FIG. 18 to the user by SDTT. When the user selects the date and time, the firmware version is updated at the specified date and time.

  The current software download service only provides a firmware upgrade function. This system can be used to download applications that play music and applications that display and edit images taken with a digital camera. However, with the current system, the following problems arise due to the increase in the number of download applications and the diversification of types.

  First, it is necessary to have means for presenting a plurality of download application information and detailed information, for example, the name and content of the application to the user.

  Second, it is necessary to consider the operating environment dependency of the application. That is, depending on the operating environment (the performance of the broadcast receiving apparatus, the display capability of the display device, and the type of connected device), an application that cannot be used even if downloaded may occur. Or, since the operating environment is not recommended by the broadcaster, there is a possibility that unexpected operation / display may occur even when downloaded.

  Third, when making a download reservation for an application that requires a common module or file, it is difficult for the user to know which one to download. Even if a means for presenting the information is provided, it is troublesome to make a plurality of reservations.

  An object of this invention is to show the broadcast receiver which eliminates such an inconvenience.

  The broadcast receiving apparatus according to the present invention is a broadcast receiving apparatus that receives a digital broadcast, and includes a data receiving means for receiving a downloadable download application data and a data string including incidental information data related to the download application data, and the data Data extraction means for extracting the download application data and the incidental information data from the data string received by the reception means, data analysis means for analyzing the incidental information data extracted by the data extraction means, and extraction by the data extraction means Ancillary information accumulating means for accumulating the incidental information data, a data accumulating means for accumulating the download application data extracted by the data extracting means according to the incidental information, and the data analyzing means It characterized by having a display control means for displaying a list of at least one of the contents of the supplementary information data.

  According to the present invention, in the TS including video data, audio data, and data broadcast data, information such as download application data, download application type, schedule information for sending the download application, and recommended operating environment of the application, etc. Multiplexing has the following effects.

  First, a plurality of download application information (application name and content, etc.) can be presented to the user in the same manner as the EPG.

  Secondly, the download application is displayed in a list after performing file tally processing according to the performance of the broadcast receiving device, the display capability of the digital television, the type of connected device, and the recommended operating environment included in the incidental information of the application. You can avoid the failure to download applications that cannot be used even if they are downloaded.

  Third, when a download reservation is made for an application that requires a common module or file, the user can easily make a download reservation without knowing which one to download.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic block diagram of a broadcast receiving apparatus according to the first embodiment of the present invention.

  A signal received by an antenna (not shown) is input to the tuner 101. The tuner 101 demodulates the input signal and performs processing such as error correction to generate digital data in a format called a transport stream. The generated transport stream (TS) data is input to the descrambler 102.

  When descrambler 102 receives TS data that has been scrambled for viewing restriction from tuner 101, descrambler 102 cancels scramble based on the key information for descrambling generated in IC card control unit 116.

  Reference numeral 201 denotes TS data in which video data / audio data for a plurality of channels, EPG data, data broadcast data, download application data, incidental information data related to the download application, and the like are time-division multiplexed. The TS data 201 is transmitted in packet units indicated by TSP in FIG. 2, and a packet identifier PID is given to the header portion 202 of the TS packet TSP.

  The demultiplexer 103 uses the PID filter 204 and the section filter 205 to extract PSI (Program Specific Information) information 206 in the payload portion 203 of a predetermined TS packet, and sends it to the data stream processing unit 106. PSI defines the contents of the entire TS data. Using this information, the demultiplexer 103 extracts the video data and audio data of the designated channel and sends them to the video decoder 104 and the audio decoder 105, respectively. The demultiplexer 103 sends the data broadcast data and download application data to the data stream processing unit 106 by the same processing.

  Further, the demultiplexer 103 uses the PID filter 204 and the section filter 205 to extract the EPG data 208 in the payload portion of the predetermined TS packet and the accompanying information 209 regarding the download application, and send them to the data stream processing unit 106.

  Processing of the video data D1 will be described. The video decoder 104 performs MPEG2 decoding processing on the video data D1 input from the demultiplexer 103 and outputs the decoded video data to the display control unit 109. The display control unit 109 displays the output image of the video decoder 104 on the image display unit 111 by switching the screen according to the operation of the video decoder 104 or the remote controller 115 or multiplexing images and / or characters from other sources. . The screen configuration unit 108 will be described later. The image display unit 111 includes an image monitor and a video signal input terminal.

  Processing of the audio data D2 will be described. The audio decoder 105 performs MPEG2 decoding processing on the audio data D2 input from the demultiplexer 103 and outputs the decoded audio data to the audio control unit 110.

The TDT or TOT information is generally used for clock display of the receiving apparatus 100 and time management for program reservation.

  The data broadcasting data is repeatedly transmitted from the broadcasting station by the DSM-CC data carousel method specified in the technical material “BS digital broadcasting operation rules” by ISO / IEC13818-6 and the Japan Radio Industry Association. The data broadcast data separated by the demultiplexer 103 includes text information, script information, image information, and video / audio data, and is described in XML (extensible Markup Language) defined by W3C.

  The data stream processing unit 106 decodes text information and image information included in the EPG data, decodes text information, image information, video data, and audio data included in the data broadcast data, and transmits the obtained data via a bus. To the memory 107. The CPU 117 stores the processing result data including the display XML data in the memory 107 after performing processing described later on the data broadcast data.

  Download application data and incidental information data related to the download application are defined in this embodiment. These data transmissions include, for example, PSI (Program Specific Information), EIT (Event Information Table), DSM-CC, etc., which are specified in ISO / IEC13818 and the standards and technical data of the Japan Radio Industry Association. Tables and descriptors and their parameters may be used or extended. Another method may be adopted for transmission of download application data.

  The data stream processing unit 106 decodes the incidental information data and download application data related to the download application, extracts text information and image information from the incidental information data, and extracts text information, image information, video data, and audio data from the download application data. . The extracted data is input to the memory 107 via the bus 119. The CPU 117 stores the processing result data including the display XML data in the memory 107 after performing the processing described later on the download application data.

  When the data broadcast display instruction or the download application supplementary information display instruction from the remote controller 115 via the operation unit 113 or the light receiving unit 114 is input, the CPU 117 reads the display EPG data and the display XML data from the memory 107, and displays the screen configuration unit. It outputs to 108.

  The screen configuration unit 108 outputs a video signal based on the display EPG data and the display XML data processed and output by the CPU 117 to the display control unit 109. As described above, the display control unit 109 outputs to the image display unit 111 a video signal corresponding to the switching and composition display of the video screen, the EPG display screen, the data broadcast screen, and the like.

  The storage unit 118 has a function (means) for storing a large amount of data that cannot be stored in the memory 107 (for example, data broadcast data or download application data for a storage type). The storage unit 118 also stores profile data of the management by the CPU 117, the function of the display device set by the user, the function of the receiving device, and the connected devices connected to the receiving device. The profile data will be described later.

  Further, the IEEE 1394 interface (I / F) 121 and the modem 120 are connected to the bus 119. The IEEE 1394 I / F 121 is used to perform protocol communication and data transmission / reception with a printer connected to the receiving apparatus 100.

  FIG. 4 shows a description content example of a table (DAIT; Download Application Information Table) describing incidental information related to the download application in the present embodiment. FIG. 4 shows an example in which a plurality of pieces of application information exist in one table.

  In the header information area 401, parameter information necessary for extracting the DAIT in the demultiplexer 103, mainly Table_ID, Section_Number, and Service_ID are described. The meaning of each information is the same as the above-mentioned EIT. is there. The time zone width in which the download application is transmitted can be identified by Table_ID and Section_Number. Information on the channel through which the download application is transmitted can be identified by Service_ID.

  In the parameter description area 402 of the download application 1, the application ID assigned to each download application, the transmission start time of the download application 1, the transmission duration of the download application 1, and the download application 1 are charged or free. A flag indicating whether or not there is described.

Information on other devices and their connection interfaces (IEEE1394 I / F, etc.) is described.

  In the area 413, the same description as the parameter description area 402-412 of the application 1 is repeatedly described for other contents. When there are N applications, the area 413 describes N-1 pieces of content information.

  The DAIT shown in FIG. 4 is provided with various Table_ID, Section_Number, and Service_ID according to the time zone and channel in which the download application is transmitted, and is multiplexed and transmitted as TS information as a plurality of table information.

  Next, a user operation for displaying the EDAG and a processing operation of the receiving apparatus associated therewith will be described.

  A signal received by an antenna (not shown) is input to the tuner 101. The tuner 101 demodulates the input signal and performs processing such as error correction to generate TS data. The generated TS data is released from the key information by the descrambler 102 and output to the demultiplexer 103.

  As shown in FIG. 2, the demultiplexer 103 includes video data, audio data, and EPG data / data broadcast data / download application data / additional information data related to the download application from the TS data output from the descrambler 102. Separate (DAIT).

  The data stream processing unit 106 decodes the EPG data and DAIT separated by the demultiplexer 103, and the decoding result is input to the memory 107 via the bus 119.

  When the user presses the program guide button 303 on the remote control 115, the CPU 117 reads EPG data from the memory 107 and outputs it to the screen configuration unit 108. The screen composition unit 108 displays a list of program names and program transmission schedules on a matrix as an electronic program guide (EPG).

  When the user presses the D button 308 of the remote controller 115 following the EPG display request, the CPU 117 reads DAIT information from the memory 107 and outputs it to the screen configuration unit 108. The screen configuration unit 108 displays a list of download applications as an EPG as a download application guide (EDAG). However, when the DAIT is read from the memory 107 and output to the data stream processing unit 106, a filtering process is performed. The filtering process here is a determination process that compares the graphic function on the display device side (for example, display resolution, screen size and display format (interlaced or progressive), etc.) with the recommended operating environment on the broadcaster side. Means.

  The filtering process will be specifically described with reference to FIG. First, the CPU 117 reads DAIT information from the memory 107. Here, for explanation, an example of main information 501 used for filtering is described in the memory 107 based on the download application 1 shown in FIG.

  Reference numeral 502 denotes application type information (genre information) shown in the parameter description area 403 of FIG. Generally used for searches such as genre search.

  Reference numeral 503 denotes component information of the application indicated in the parameter description area 405 of FIG. Component information is provided as a recommended operating environment of the application by the broadcaster. Details will be described later.

  Reference numeral 504 denotes the compression format of the application shown in the parameter description area 410 of FIG.

  The CPU 117 reads the profile data 505 of the receiving device and the display device from the storage unit 118. The profile data 505 includes, for example, graphic functions such as a screen “1024 × 768 pixels”, a resolution “720p”, a color number “RGB each 8 bits (16.77 million colors)”, and an aspect ratio “16: 9” as the display capability of the display device. 506 is described, and decoding capability means 507 such as “corresponding to MPEG2 file format” and “corresponding to AAC file format” is described as the capability of the receiving apparatus.

  The CPU 117 compares the DAIT 501 with the profile data 505 using a comparison / determination unit that is one of the functions. For example, it is assumed that information such as a display screen “1024 × 768 pixels”, a resolution “720i”, and the number of colors “RGB each 8 bits” is described in the component information 503 in DAIT as a recommended operating environment. Further, it is assumed that information “MPEG2 file format” is described in the compression format 504.

  The CPU 117 compares the component information 503 with the graphic function 506 and determines whether or not the display device side satisfies the component information recommended by the broadcaster side. The CPU 117 also determines whether the broadcast format is compatible with the compression format 504 and the decodable means 507.

  In the above-described example, the graphic function 506 satisfies the component information 503, and similarly the decodable means 507 satisfies the compression format 504. Therefore, the supplementary information of the download application is supplied to the screen configuration unit 108 via the data stream processing unit 106. Is done.

  If the graphic function 506 of the profile data 505 is, for example, information of a screen “640 × 480 pixels”, a resolution “480p”, and the number of colors “RGB each 8 bits”, this graphic function satisfies the above component information. Therefore, the incidental information of the download application is not output to the screen configuration unit 108.

  Also, in the compressed format, for example, if it is “MPEG4 file format”, the decodeable means 507 does not satisfy this compressed format, so the incidental information of the download application is not output to the screen configuration unit 108.

  The screen configuration unit 108 configures a screen (EDAG) that displays a list of download schedules and incidental information of download applications. This information EDAG is displayed by the display control unit 109 and the image display unit 112.

  The description regarding the graphic function, the component information, the compression format, and the decodable means is an example, and the present invention is not limited to the above case.

  As a result of the above processing, only information on the download application that has been subjected to the filtering processing so as to satisfy the performance of the receiving device and the display device is displayed on the screen display unit 112 as EDAG.

  Next, the display form of EDAG will be described with reference to FIGS.

  The selected frame 606 can be moved by the cursor key 303 of the remote controller. In FIG. 6, a frame having the data transmission channel number “BS2” and the schedule time information “13: 0 to 14:00” is selected. When the user presses the enter button 305 while the selection frame 606 is selected, the selection cursor moves to the contents in the selection frame 606. The selection cursor 607 in the selected frame 606 can be moved up and down only within the selected frame 606.

  Reference numeral 608 denotes a symbol indicating that there is information not displayed on the display screen. FIG. 6 shows that there is a content of the download application for the item selected by the selection cursor 607 in the selected frame 606.

  As a result, the list information of download applications can be presented to the user.

  In addition, download of a desired download application can be reserved from the download application list information.

  Furthermore, when displaying a list of download applications, a comparison judgment (filtering process) is performed between the performance of the receiving device and the display device and the recommended operating environment of the application, and only usable download application information is presented to the user. You can avoid failures such as downloading an application that cannot be used.

  Although two display methods have been described here, the presentation method to the user is not limited to the above case.

  Next, a second embodiment of the present invention will be described.

  In addition to the functions in the first embodiment, the CPU 117 stores, as profile data, identification information of connected devices connected to the IEEE 1394 I / F 121 (for example, identification information such as printers and digital cameras, manufacturer information, version numbers, etc.). 118 has a function of accumulating.

  A flow of operation by the user and a processing operation of the receiving apparatus associated therewith will be described. A signal received by an antenna (not shown) is input to the tuner 101. The tuner 101 demodulates the input signal and performs processing such as error correction to generate TS data. The generated TS data is output to the demultiplexer 103 after the key information is released by the descrambler 102.

  As shown in FIG. 2, the demultiplexer 103 includes video data, audio data, and EPG data / data broadcast data / download application data / additional information data related to the download application from the TS data output from the descrambler 102. Separate (DAIT).

  The data stream processing unit 106 decodes the EPG data and DAIT separated by the demultiplexer 103, and the decoding result is input to the memory 107 via the bus 119.

  When the user presses the program guide button 303 on the remote control 115, the CPU 117 reads EPG data from the memory 107 and outputs it to the screen configuration unit 108. The screen composition unit 108 displays a list of program names and program transmission schedules on a matrix as an electronic program guide (EPG).

  When the user presses the D button 308 of the remote controller 115 following the EPG display request, the CPU 117 reads DAIT information from the memory 107 and outputs it to the screen configuration unit 108. The screen configuration unit 108 displays a list of download applications as an EPG as a download application guide (EDAG). However, when the DAIT is read from the memory 107 and output to the data stream processing unit 106, a filtering process is performed. Here, the filtering process includes the performance of the digital television apparatus (the state of the graphic function, the decodable means and the devices (1394 I / F, card reader, etc.) connected to the digital television) and the recommended operating environment of the broadcaster. Is a judgment process for comparing the two.

  The filtering process here will be specifically described with reference to FIG. However, the data stream processing unit 106, the memory 107, the screen configuration unit 108, and the storage unit 118 in FIG. 11 have the same functions as the corresponding components in FIG.

  First, the CPU 117 reads DAIT information from the memory 107. Here, for explanation, reference is made to the information 1101 of the download application 2 shown in FIG.

  The CPU 117 reads the profile data 1105 of the receiving device and the display device from the storage unit 118. For example, the profile data 1105 can be decoded as a display capability of the display device as a graphic function 1106 such as resolution, number of colors, and screen size, and as a capability of the reception device as to whether the MPEG2 file format or AAC file format is supported. 1107, connected device data 1108 such as whether the receiving device has output means such as IEEE1394 I / F, and whether or not devices such as a printer and a digital camera are connected to the output device, have been connected so far Connected device history data 1109 indicating device information (for example, a manufacturer identification ID, product model number, and version number for a printer) is stored in the storage unit 118. The profile data 1105 is appropriately updated by the CPU 117 when a connected device is connected.

  The CPU 117 compares the DAIT with the profile data using a comparison / determination unit that is one of the functions.

  First, the component information 1102 in DAIT is compared with the graphic function 1106 in the profile data of the receiving device. Since a specific comparative example is the same as that shown in the first embodiment, a description thereof will be omitted here.

  The compression format in DAIT is compared with the decodable means 1107 in the profile data of the receiving apparatus. Since a specific comparison example is the same as that shown in the first embodiment, the description thereof is omitted here.

  The device information 1104 in the DAIT is compared with the connected device data 1108 and the connected device history 1109 in the profile data of the receiving apparatus. Since the device information 1104 describes information on the necessary connected device, the device information 1104 is compared with the connected device data 1108 in order to hold information on the actually connected device.

  If the connected device necessary for using the application is connected, the data stream is added with the information indicating that the connected device is connected (information that the download application can be used) along with the accompanying information of the download application. The data is output to the screen configuration unit 108 via the processing unit 106.

  If the connected device necessary for using the application is not connected, the device information 1104 and the connected device history 1109 are compared.

  If the device necessary for using the application is included in the information of the connected device history 1109, information to that effect (for example, reconnecting a device connected in the past, or turning on the power if the power is off) Information that can be used by the operation) is added to the supplementary information of the download application information, and is output to the screen configuration unit 108 via the data stream processing unit 106.

  If the device necessary for using the application is not included in the connected device history 1109, information to that effect (information indicating that the application cannot be used at present) is added to the incidental information, and the data stream processing unit 106 To the screen composition unit 108.

  The screen configuration unit 108 configures a screen (EDAG) for displaying a list of download application transmission schedules and incidental information and displays the screen (EDAG) on the image display unit 112 via the display control unit 109.

  In addition, the screen configuration unit 108 is configured in an EDAG display form (described later) of information added to the application (information indicating whether or not the application can be used obtained by comparing the device information with the connected device data or the connected device history). Then, the image is displayed by the image display unit 112 via the display control unit 109.

  When the user connects a connected device while displaying EDAG, the CPU 117 newly creates profile data of the connected device data 1108 and stores it in the storage unit 118. The newly accumulated connection device data 1108 and device information 1104 are compared, information corresponding to the result is added to the supplementary information of the download application as described above, and the screen composition unit 108 is transmitted via the data stream processing unit 106. To output.

  As a result of the above operation, the screen display unit 112 displays, as EDAG, download application information that has been subjected to filtering processing taking into account the performance of the receiving device and the display device and the state of the connected device.

  Even if the connected device is connected or disconnected while the EDAG is displayed, the connected device data and connected device history are created, compared with the incidental information of the download application, and the comparison result is displayed, so the latest download application information is displayed in EDAG. It can be reflected. That is, the EDAG can be updated in real time according to the connection of the connected device.

  Next, with reference to FIG. 12, the display form of a present Example is demonstrated. FIG. 12 is obtained by adding the present example to Example 2 of the display form of the first example. Since 1201 to 1206 have similar functions and meanings, description thereof will be omitted.

  Reference numeral 1207 indicates that the downloaded application can be used immediately after downloading. That is, the content information of the download application in which “information that the download application is usable” is added to the incidental information of the download application. In this embodiment, it is displayed in blue.

  Reference numeral 1208 indicates that the connected device has been connected before and the download application can be used by reconnecting the connected device. That is, the content information of the download application includes “information that can be used by an operation such as reconnecting a device connected in the past or turning on the power if the power is off” in the incidental information of the download application. In this embodiment, it is displayed in yellow.

  Reference numeral 1209 indicates that the connected device has never been connected, and even if the download application is downloaded at this stage, there is a high possibility that the application cannot be used. That is, the content information of the download application in which “information that the application cannot be used at present” is added to the incidental information of the download application is shown. In this embodiment, it is displayed in red.

  If the printer or digital camera is inserted or removed while EDAG is displayed, the selection cursor changes from “blue” to “yellow” or “red” to “blue”, reflecting the connected device data and connected device history. Present the latest information to the user.

  In the present embodiment, the usage information of the download application is visually presented by coloring the cursor with three colors of “blue”, “yellow”, and “red”. However, the cursor frame is colored or the pattern is changed. Another expression method such as adding a symbol to the display column can be adopted.

  As a result, the download application information can be presented to the user, and the download application information that can be used is visually provided. Can be avoided.

  Furthermore, by managing the profile data of the connected device, the user can visually grasp whether the application can be used or not simply by connecting.

  In the parameter description area 1306, link destination information is described. This consists of text information for displaying the link destination on the EDAG.

  Next, the flow of operation by the user and the processing operation of the receiving apparatus associated therewith will be described. However, since the application module link descriptor is valid when a download application is reserved, the description will focus on program reservation.

  First, in the receiving apparatus 100, the CPU 117 reads DAIT information from the memory 107 and outputs it to the screen configuration unit 108 via the data stream processing unit 106. However, when the DAIT is read from the memory 107 and output to the data stream processing unit 106, the filtering process described in the first and second embodiments is performed. By this filtering process, the display of only usable applications or the application information indicating whether or not the applications can be used is displayed in a visually easy-to-understand manner for the user.

  When the user executes an application reservation operation, the CPU 117 checks whether an application module link descriptor is included in the DAIT of the program information to be reserved. The reservation operation and display mode will be described later.

  The CPU 117 determines whether or not an application module link descriptor is included in the DAIT of the download application for the download application subjected to the reservation operation.

  If the application module link descriptor is included, the DAIT information of the link destination module is taken out, the time information at which the download is completed is taken out from the parameter description area in the DAIT, and a reservation confirmation screen described later (see FIG. 17). ) Display on top.

  When the reservation is continued by the user on the reservation confirmation screen, the CPU 117 also performs a reservation process for the module specified by Original_Network_ID, Transport_Stream_ID, Service_ID, Application_ID, and Application_Module_ID described in each parameter description area.

  Further, the CPU 117 extracts DAIT information of the link destination module based on Original_Network_ID, Transport_Stream_ID, Service_ID, and Application_ID, and if there is information about the link destination module, makes a download reservation.

  The display form of EDAG by the above operation will be described with reference to FIGS. 1401 to 1408 in FIG. 14 correspond to 601 to 608 in FIG. Since 1501 to 1509 in FIG. 15 correspond to 701 to 709 in FIG. 7, detailed description is omitted. Since 1601 to 1607 in FIG. 16 correspond to 801 to 808 in FIG. 8, detailed description thereof is omitted.
