  The broadcast wave receiving unit 11 receives a broadcast wave broadcast from the broadcast station 1 via the broadcast antenna 2.

  The first separation unit 12 demodulates the broadcast wave received by the broadcast wave reception unit 11 and extracts a broadcast signal, that is, a TS packet from the broadcast wave. Then, the first separation unit 12 refers to the PSI / SI of the TS packet, determines the type of data included in the TS packet, and extracts various data such as video, audio, and EIT. In addition, the first separation unit 12 extracts the AIT by referring to the section and the PES according to a predetermined AIT transmission method.

  Subsequently, when the data included in the PES of the TS packet is audio data, the first separation unit 12 outputs the audio data to the audio control unit 18. In addition, when the data included in the PES of the TS packet is video data, the first separation unit 12 outputs the video data to the display control unit 19.

  Further, the first separation unit 12 stores the extracted EIT and other various data in the memory 22. Further, when the first separation unit 12 extracts the AIT, the first separation unit 12 outputs the extracted AIT to the broadcast AIT acquisition unit 13.

  The broadcast AIT acquisition unit 13 acquires the AIT output from the first separation unit 12 and stores it in the AIT storage unit 23.

  The communication unit 14 is a communication interface that transmits and receives data to and from the service server 3 via the communication network N.

  The second separation unit 15 determines the type of data received by the communication unit 14. When the second separation unit 15 determines that the received data is an AIT, the second separation unit 15 outputs the AIT to the communication AIT acquisition unit 16. When the second separation unit 15 determines that the received data is an application, the second separation unit 15 outputs the application to the application execution control unit 17.

  For example, when the second separation unit 15 determines that the received data is a TS packet, the second separation unit 15 extracts various data such as video, audio, and AIT from the TS packet. The second separation unit 15 outputs this AIT to the communication AIT acquisition unit 16 when the AIT is extracted, and outputs this data to the application execution control unit 17 when data other than the AIT is extracted.

  The communication AIT acquisition unit 16 acquires the AIT output from the second separation unit 15 and stores it in the AIT storage unit 23.

  The application execution control unit 17 acquires an application based on a user's execution instruction via the AIT or the remote controller R, and controls execution of the acquired application. Then, the application execution control unit 17 outputs the audio data of the application content acquired from the service server 3 by executing the application to the audio control unit 18, and the video data of the application content acquired from the service server 3. The data is output to the display control unit 19.

FIG. 4 is a diagram illustrating an example of the AIT described in the XML format. As described above, the AIT includes one or more pieces of individual management information corresponding to one or more applications and managing each of the one or more applications.
Specifically, the codes described from the <mhp: Application> tag to the </ mhp: Application> tag shown in FIG. 4 correspond to the individual management information related to one application. In the AIT, a plurality of pieces of individual management information can be described by newly describing individual management information of other applications after the </ mhp: Application> tag.

  Of the codes corresponding to the individual management information, for example, the code corresponding to the <mhp: appId> tag indicates the application ID (identification information). The code corresponding to the <mhp: controlCode mhp: type = “ARIB-J”> tag indicates the life cycle control information of this application, and “AUTOSTART” shown in FIG. Is life cycle control information for automatically executing A code corresponding to the <mhp: location> tag indicates location information indicating the location of the application. As shown in FIG. 4, the location information describes the address of the service server 3 as the location of the application. In the location information, the receiver 4 can be designated as the location of the application.

  The application execution control unit 17 monitors the AIT storage unit 23 and refers to control information related to the life cycle described in the AIT when a new AIT is stored. Then, when the control information related to the life cycle indicates “automatic execution”, the application execution control unit 17 uses the location information described in the AIT as an application acquisition destination, and the communication unit 14 and the second separation unit. The application is acquired from the service server 3 via 15 and the acquired application is executed. In this case, the application is automatically executed without receiving an explicit operation instruction from the user of the receiver 4.

  The application execution control unit 17 receives an application execution instruction from the user of the receiver 4 via the remote controller R. For example, the remote control R is provided with a Hybridcast (registered trademark) button, and the application execution control unit 17 accepts selection of an application to be executed in response to the user pressing the Hybridcast button. An instruction to execute a menu screen is received. In response to receiving the menu screen execution instruction, the application execution control unit 17 refers to the AIT storage unit 23 and identifies the AIT of the executable application. Then, the application execution control unit 17 outputs video data constituting a menu screen from which an application corresponding to the identified AIT can be selected to the display control unit 19 and causes the display 21 to display this menu screen. When an application selection operation is received from the user of the receiver 4 via the remote controller R, the application execution control unit 17 refers to the location information of the application described in the AIT, acquires the application, and executes the application. .

  The application causes the application execution control unit 17 to acquire video data and audio data of the application content from the service server 3. Then, the application execution control unit 17 outputs the audio data of the application content acquired by the application to the audio control unit 18 and outputs the video data of the application content acquired by the application to the display control unit 19. Here, when the application is an application that provides application content linked to the program content, the video data and audio data of the application content are displayed on the display 21 in conjunction with the video data and audio data of the program content. .

  Further, the application execution control unit 17 monitors the AIT storage unit 23, and when the AIT describing the individual management information corresponding to the application being executed is newly stored in the AIT storage unit 23, it is included in the individual management information. The running application is controlled based on the life cycle control information. For example, when the life cycle control information of the application indicates “end”, the application is ended.

  The audio control unit 18 outputs the audio data output from the first separation unit 12 to the speaker 20 while synchronizing with the video data whose display is controlled by the display control unit 19. Further, when the audio data output from the application execution control unit 17 can be synchronized with the video data whose display is controlled by the display control unit 19, the audio control unit 18 transmits the audio data to the speaker while synchronizing with the video data. 20 is output.

  The display control unit 19 displays the video data output from the first separation unit 12 on the display 21 in synchronization with the audio data output-controlled by the audio control unit 18. In addition, when the video data output from the application execution control unit 17 can be synchronized with the audio data output-controlled by the audio control unit 18, the display control unit 19 displays the video data while synchronizing with the audio data. 21 is displayed.

The memory 22 stores meta information of program content such as EIT and various other information.
The AIT storage unit 23 stores the AIT acquired by the broadcast AIT acquisition unit 13 and the communication AIT acquisition unit 16.

  In the present embodiment, the AIT attribute multiplexed on the broadcast signal or the AIT attribute multiplexed on the program content by the service server 3 includes search information for searching for an application.

  When the application execution control unit 17 creates video data that configures a menu screen on which an application can be selected based on the AIT described above, the application selection information (for example, an application icon) is included in the AIT attribute. Associate search information.

  Here, as the search information for searching for an application, for example, a subject code can be cited. The target person code is a code indicating the target person of the application provided through communication. Examples of target persons of the application include healthy persons, elderly persons, disabled persons, foreigners, and the like.

  For example, “0” for an application for a healthy person (general), “1” for an application for an elderly person, “2” for an application for a disabled person, “3” for an application for a foreigner, etc. Target code is used.

  When one item is selected from the application selection information, the cooperative application acquisition unit 24 searches the service server 3 for an application that matches the search information, based on the search information corresponding to the one item. .

  More specifically, when one item is selected from the application selection information, the cooperative application acquisition unit 24 sends the target person code corresponding to the one item via the communication unit 14 to the service server 3. While transmitting to (search server 3c), it requests the service server 3 (search server 3c) to search for an application that matches the target person code.

  Here, in the application distribution server 3b, all or some of the various applications operating on the receiver 4 include a subject code as application metadata. That is, the application distribution server 3b manages the application including the target person code.

  Then, the search server 3c searches for an application from the application distribution server 3b based on the target person code transmitted from the receiver 4.

  More specifically, the search server 3c searches the application distribution server 3b for an application including the target person code transmitted from the receiver 4. Then, the search server 3 c transmits the searched search result (for example, a list of URLs for acquiring an application including the target person code that matches the target person code) to the receiver 4.

  When receiving the search result from the search server 3 c, the cooperative application acquisition unit 24 transmits the received search result to the application execution control unit 17. For one item selected from the application selection information, the application execution control unit 17 presents a list of applications including the target person code corresponding to the one item.

  5 and 6 are screen transition diagrams showing specific examples of processing according to the present embodiment. As illustrated in FIG. 5, the application execution control unit 17 receives an instruction to execute a menu screen for receiving selection of an application to be executed in response to the user of the receiver 4 pressing the Hybridcast button on the remote controller R. In response to receiving an instruction to execute a menu screen, the AIT storage unit 23 is referred to and an AIT of an executable application is specified. Then, the application execution control unit 17 outputs video data constituting a menu screen from which an application corresponding to the identified AIT can be selected to the display control unit 19 and causes the display 21 to display the menu screen M. In addition, when the application execution control unit 17 creates video data that configures the menu screen M on which an application corresponding to the AIT can be selected, the application execution control unit 17 stores the AIT in the selection information (for example, application icon) corresponding to the AIT. Search information included in the attribute of is added. In FIG. 5, the menu screen M displays icons M1 to M3 for selecting an application.

  When the icon M2 is selected from the icons M1 to M3, the cooperative application acquisition unit 24 obtains a target person code corresponding to the icon M2 (for example, a target person code “3” indicating an application for a foreigner). While transmitting to the service server 3 (search server 3c) via the communication part 14, it requests the service server 3 (search server 3c) to search for an application that matches the target person code “3”.

  Then, the search server 3c searches the application distribution server 3b for an application including the target person code “3”. Then, the search server 3 c transmits the searched search result (for example, a list of URLs for acquiring an application including the target person code “3”) to the receiver 4.

  When receiving the search result from the search server 3 c, the cooperative application acquisition unit 24 transmits the received search result to the application execution control unit 17.

  Then, as illustrated in FIG. 6, the application execution control unit 17 performs the subject code “3” corresponding to the icon M2 for the icon M2 selected from the menu screen M based on the received search result. Is output to the display control unit 19 so that the menu L1 is displayed on the display 21.

  As shown in FIG. 6, when the application including the target person code “3” has the summary information as metadata, the application execution control unit 17 displays the summary information L2 together with the menu L1. 21 is displayed.

  Here, the overview information is information indicating an overview of the application. For example, an application for elderly people that performs speech speed conversion on the audio data of the program content and outputs the audio data of the program content at a slower speed than usual. , An application for the hearing-impaired person who adds sign language screen presentation to the program content, and a foreign language that adds translation subtitles in languages other than Japanese (eg English, Chinese, Korean, Russian, etc.) to the program content This is information indicating that the application is for humans. The user can select a desired application based on this summary information.

  When the user of the receiver 4 selects one menu (for example, the application for Chinese translation subtitles in FIG. 6) from the menu L1, the application execution control unit 17 selects the selected one. An application corresponding to the menu is acquired from the service server 3 (application distribution server 3b). Then, the application execution control unit 17 executes the application acquired from the service server 3 (application distribution server 3b). For example, the application execution control unit 17 causes the display 21 to display the Chinese translation subtitles of the program content by the application for Chinese translation subtitles acquired from the application distribution server 3b together with the program content by broadcast waves.

  As described above, according to the present embodiment, the receiver 4 adds the search information including the target person code indicating the target person of the application to the selection information of the application. Search can be performed. Therefore, the receiver 4 can search and acquire a desired application by a user with a simple operation.

  In addition, since the target person code is included as metadata in the AIT and the application, the receiver 4 can search for a cooperative application desired by the user from a large number of cooperative applications.

  In addition, since the receiver 4 displays the summary information indicating the summary of the application, the user can easily grasp what kind of application the searched cooperative application is.

  Moreover, since the application distribution server 3b and the search server 3c search for an application based on the target person code included in the search information, it is possible to search for a desired cooperative application from among a large number of applications.

  In addition to the above-described configuration, the receiver 4 may include a setting unit 25 that can set search information in advance by a user operation using the remote controller R or the like.

  When the application execution control unit 17 creates video data that configures a menu screen on which an application corresponding to the AIT can be selected, the application execution control unit 17 stores the setting unit in the selection information (for example, application icon) corresponding to the AIT. The search information preset by 25 may be added.

  Thereby, the receiver 4 can search and acquire a desired application using the set subject code by setting the subject code in advance.
