The application identifier 902 is identification information configured to identify an application unit, and includes an organization identification identifying an enterprise and an application identification numbered for each enterprise. The application unit is a set of HTML documents and reference resources thereof, with the HTML document existing in the location specified by the application acquisition destination information 905 as the entry document. The application control code 903 defines operation control for the target application, and one of (1) automatic activation, (2) operation enable, (3) end, and (4) prefetch is described. . The application profile 904 is a value indicating the function of the television receiver required by the application, and indicates a combination of functions that the television receiver has as an option. The availability of the application is determined by referring to this value.

  The application acquisition destination information 905 is information for specifying an acquisition destination of the application, and is location information for acquiring an HTML document to be referred to first when the application is started. Since the application is assumed to be transmitted by broadcasting and to be stored in a server device on the communication network, the location information specified in the application acquisition destination information 905 also corresponds to the case of both the broadcast acquisition and the communication acquisition. A provision is made. The application boundary and access restriction setting 906 is information indicating an operable range as a broadcast managed application as a set of one or more areas (URL: Uniform Resource Locator). Also, the access restriction to the broadcast resource for each area is set for each function. Application boundary and access restriction setting 906 specifies the range of document transition to prevent transition to unexpected document or access to inappropriate broadcast resource by chain of document transition from the entry document at application startup. Do. In addition, it is possible to set an access right to a specific broadcast resource in area units within the range of the document transition.

  The activation priority 907 defines which of the data broadcast by the broadcast service and the broadcast managed application by the HTML document is to be launched at the same time. Designating data broadcasting as top priority unconditionally on the PMT, designating activation priority of a specific application type on the PMT, and designating activation priority of a target application in the activation priority 907, Shall be possible. The cache information 908 is information used for cache control when holding application resources in preparation for reuse of the application. This information makes it possible to cache application resources assuming reuse even after the end of the application. The server access distribution parameter 909 is a parameter set for distributing access in order to reduce the load on the server where access is concentrated at the acquisition destination of the application or the like.

It is possible to define what to do.

  FIG. 7A is an operation sequence diagram showing an example of an operation sequence of the broadcast cooperation application in the case where the broadcast cooperation application is defined to be activated preferentially. The figure shows a series of flow from when the broadcast receiving apparatus 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

  When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing desired by the user and acquires a TS, next, the main control unit 101 acquires a PMT data string separated by the first separation unit 132. Then (S101), the activation priority described in the PMT is confirmed. When confirming that the start priority of the broadcast cooperation application is high in the process of S101 (S102), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S103), and the acquired AIT The application control code 903 of the data string is confirmed (S104). In the process of S104, when the application control code 903 is "automatic start", the application profile 904 of the acquired AIT data string is further confirmed (S105), and the broadcast cooperation application designated by the AIT is executed. When it is confirmed that it is possible, the transmission request of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition destination information 905. (S106).

  The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving apparatus 100 as necessary, based on the control of the application management / distribution execution unit 4103, and then performs the processing in the application storage area 4013. Delivery of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S107). A known method may be used for the authentication process, and the detailed description will be omitted. Next, the application engine 162 of the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, received via the LAN communication unit 121, based on the control of the application control unit 161. (S108).

  FIG. 7B is an operation sequence diagram showing an example of an operation sequence of the broadcast cooperative application in the case where it is defined that the data broadcast by the broadcast service is preferentially activated. The figure shows a series of flow from when the broadcast receiving apparatus 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

  When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing desired by the user and acquires a TS, next, the main control unit 101 acquires a PMT data string separated by the first separation unit 132. Then (S201), the activation priority described in the PMT is confirmed. In the process of S201, it is confirmed that the start priority of the data broadcast by the broadcast service is high (S202), the data broadcast reception processing unit 141 acquires the BML data string separated by the first separation unit 132, and the BML document is obtained. It reproduces (S203). When the automatic start of data broadcasting is set by the BML document, and when the user makes a start request for data broadcasting using the operation terminal (the portable information terminal 700, the remote control, etc.) (S204), the data broadcasting engine Then, the data broadcasting screen information is generated by executing the reproduced BML document, and displayed on the video display unit 173 (S205).

  After the process of S205 or simultaneously with the process of S205, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S206), and confirms the application profile 904 of the acquired AIT data string. (S207). When it is confirmed in the process of S207 that execution of the broadcast cooperation application designated by the AIT is possible, an entry button to the executable broadcast cooperation application is displayed on the data broadcast screen. The entry button may always be displayed, and the color scheme may be changed from the inactive color to the active color only when the broadcast cooperation application can be executed. The shape may be changed to switch between the inactive state and the active state of the entry button.

  When the user selects the entry button using the operation terminal (S208), the data broadcasting engine 142 executes the BML document and ends the process of generating data broadcasting screen information (S209). Subsequently, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S210), and confirms the application acquisition destination information 905 of the acquired AIT data string. Furthermore, based on the information described in the application acquisition destination information 905 confirmed in S210, the transmission request of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S211).

  The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving apparatus 100 as necessary, based on the control of the application management / distribution execution unit 4103, and then performs the processing in the application storage area 4013. Delivery of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S212). Next, the application engine 162 of the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, received via the LAN communication unit 121, based on the control of the application control unit 161. (S213).

  FIG. 7C is an operation sequence diagram showing an example of an operation sequence of the broadcast cooperative application when no priority activation is defined. The figure shows a series of flow from when the broadcast receiving apparatus 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

  When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing desired by the user and acquires a TS, next, the main control unit 101 acquires a PMT data string separated by the first separation unit 132. Then (S301), the activation priority described in the PMT is confirmed. When confirming that the start priority of the broadcast cooperation application is high in the process of S301 (S302), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S303), and the acquired AIT The application control code 903 of the data string is confirmed (S304). In the process of S304, when the application control code 903 is not "automatic start" but "startable", the display of the broadcast program is continued without starting any of the data broadcasting by the broadcast service and the broadcast cooperation application.

  In the case where the user makes a start request for data broadcasting using the operation terminal in a state after the processing of S304 (S305), acquisition of a BML data string and BML as in the processing after S205 of FIG. 7B. Reproduction of the document, generation of data broadcast screen information, and the like are performed (but not shown). On the other hand, when the user issues an activation request for the broadcast cooperation application launcher using the operation terminal in a state after the processing of S304 (S306), the AIT data separated by the first separation unit 132 by the application control unit 161. A column is acquired (S307), and the application profile 904 of the acquired AIT data column is confirmed (S308). Furthermore, the application control unit 161 displays a list of executable broadcast cooperation applications on the video display unit 173 as a broadcast cooperation application launcher (S309).

  When the user selects a predetermined broadcast cooperation application from the broadcast cooperation application launcher displayed in S309 using the operation terminal (S310), the application control unit 161 extracts the AIT data string separated by the first separation unit 132. Acquire (S311), and confirm the application acquisition destination information 905 of the acquired AIT data string. Furthermore, based on the information described in the application acquisition destination information 905 confirmed in S311, the transmission request of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S312).

  The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving apparatus 100 as necessary, based on the control of the application management / distribution execution unit 4103, and then performs the processing in the application storage area 4013. Delivery of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S313). Next, the application engine 162 of the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, received via the LAN communication unit 121, based on the control of the application control unit 161. (S314).

  In the start sequence of the broadcast cooperation application described with reference to FIGS. 7A to 7C, although an example in which the AIT is acquired from the broadcast wave is described, the predetermined server apparatus specified by the information description of the PMT or the like You may acquire the AIT file from. Also, the acquisition of the broadcast cooperation application may be performed from the broadcast wave, not from the server apparatus (service provider server 400) on the network. That is, when the location information described in the application acquisition destination information 905 of the AIT indicates a broadcast wave, the HTML data string transmitted by the application control unit 161 by the data carousel method or the like and separated and output by the first separation unit 132 The HTML document may be reproduced from the above, and the application engine 162 may execute the reproduced HTML document (broadcast cooperation application).

  If there is no information for specifying the activation priority when data broadcasting by the broadcasting service and the broadcast cooperation application exist simultaneously on the PMT, the activation is performed only by the information such as the application control code 903 of the AIT and the activation priority 907. You may check the priority. Similarly, even if acquisition of the information on the PMT fails, the activation priority may be confirmed only by information such as the application control code 903 of the AIT and the activation priority 907. That is, regardless of the information on the PMT, the AIT is periodically checked, and when there is a broadcast cooperation application specified by “automatic start” in the application control code 903 of the AIT, If priority is given to activation and no broadcast cooperation application designated by “automatic activation” is present in the application control code 903 of the AIT, activation of data broadcasting by the broadcasting service may be prioritized.

  In addition, when there is no response from the service provider server 400 for a predetermined time or more when the distribution request of the broadcast cooperation application is made in S106, S211, S312, a message such as “Please wait for a while” is displayed on the image display section 173. It may be displayed. Alternatively, in this case, a message may be displayed asking the user to stop the execution of the broadcast cooperation application.

  Further, it goes without saying that the activation sequence of the broadcast cooperation application is not limited to the above three patterns, and may be activated by different sequences.

[EPG screen of broadcast receiver]
FIG. 16A is a screen display diagram showing an example of an electronic program guide (EPG) display screen in the broadcast receiving apparatus 100 of the present embodiment. The EPG display screen 173 e is a distribution schedule of broadcast programs in the digital broadcast service of the present embodiment, which is created based on the program information data string output from the first separation unit 132 by the main control unit 101. It is assumed that the EPG display screen 173e is displayed on the video display unit 173 by selecting the program guide key 741a7 of the basic screen 741a of the cooperation control application.

  In the present embodiment, the EPG display screen 173e has a matrix shape in which the vertical axis represents time and the horizontal axis represents service ID (channel), and detailed information of each broadcast program broadcasted on each channel in each time zone is displayed. indicate. As shown in FIG. 16A, the detailed information 173e1 of each broadcast program mainly includes a title area 173e2 and a detailed explanation area 173e3.

  In the title area 173e2, a program title of each broadcast program and a symbol representing an attribute of each broadcast program are displayed. The symbol or the like representing the attribute of each broadcast program is, for example, a symbol obtained by symbolizing "New" which means that it is a new program, or a symbol which is symbolized "Replay" which means that it is a rebroadcast program. Etc. Alternatively, it may be a mark or the like that symbolizes "data" which means that it supports data broadcasting by the broadcasting service. In the case of a broadcast program for which a broadcast cooperation application that can be executed by the broadcast receiving apparatus 100 according to the present embodiment is prepared, a mark or the like may be used as "Linkage" indicating that. The detailed explanation area 173e3 displays related information such as the program content and cast of each broadcast program, the URL of the homepage introducing each broadcast program, and the like.

  In addition, the mark etc. which symbolized the said "Linkage" displayed on the title area 173e2 show an information display apparatus as a result of confirmation of the application profile 904, even when the broadcast cooperation application is prepared for the said broadcast program. If the execution at 100 is not possible, it may not be displayed. Further, the symbol displayed on the title area 173e2 and indicating "Linkage" indicating that it is a broadcast program for which the above-mentioned executable broadcast cooperation application is prepared can further cooperate with the portable terminal device. Depending on whether or not, the color, shape, font, etc. may be changed. When the cooperative operation with the portable terminal device is possible, a mark in which “Mobile” is symbolized may be displayed together with the mark in which “Linkage” is symbolized.

  It should be noted that the presence or absence of the display of the mark “Linkage” and the mark “Mobile” are described in advance in the EIT information including detailed information of each broadcast program. Whether it is a broadcast program for which a broadcast cooperation application that can be executed by the broadcast receiving apparatus 100 according to the embodiment is prepared, and whether or not the executable broadcast cooperation application can cooperate with a mobile terminal device, It may be controlled by acquiring information such as. Alternatively, the information acquired from program distribution information of a digital broadcast program prepared in a predetermined server device on the Internet 200 may be an electronic program guide created based on a program information data string acquired from a broadcast wave of the digital broadcast service. It may be added.

  As described above, it is possible to cooperate on the EPG display screen 173e with a mark that symbolizes "Linkage" indicating that it is a broadcast program for which an executable broadcast cooperation application is prepared, and a cooperative operation with a mobile terminal device By displaying the sign of “Mobile” indicating “”, it is possible for the user to easily grasp the support situation of the broadcast program in the broadcast receiving apparatus 100 to the broadcast communication cooperation service. Needless to say, the mark obtained by symbolizing predetermined characters representing the attributes of each of the broadcast programs may be substituted for the characters themselves, sentences, and the like. By changing the background color of the detailed information 173e1 of each broadcast program, the support status of each broadcast program to the broadcast communication cooperation service may be indicated. Further, the mark “Linkage” and the mark “Mobile” are not usually displayed in the title area 173e2, and pop up only when each broadcast program is selected by the program selection cursor 173e4. It may be displayed.

  The broadcast receiving apparatus 100 of the present embodiment has a function of performing viewing reservation and / or recording reservation for each broadcast program on the EPG display screen 173e. For example, while the EPG display screen 173e is displayed, the program selection cursor 173e4 on the EPG display screen 173e is moved using the cursor key 741ac of the basic screen 741a of the cooperation control application, and an arbitrary broadcast program is moved with the enter key 741ad. The user makes a viewing reservation and / or a recording reservation of the selected broadcast program by selecting.

  In the above process, when the broadcast program for which the viewing reservation and / or the recording reservation has been performed is a broadcast program corresponding to a broadcast communication cooperation service, the broadcast is triggered by the viewing reservation and / or the recording reservation being performed. The acquisition of the broadcast cooperation application prepared for the broadcast program may be started without waiting for the broadcast start time of the program. That is, information (location information such as a URL) specifying the acquisition destination of the broadcast cooperation application is described in EIT information including detailed information and the like of each broadcast program. In this way, the broadcast receiving apparatus 100 can grasp the information of the acquisition destination of the broadcast cooperation application prepared for each broadcast program when the broadcast program is selected by the program selection cursor 173e4. Become. Therefore, the broadcast receiving apparatus 100 can start acquisition of the broadcast cooperative application before the broadcast start time of the broadcast program.

  If the broadcast program for which the viewing reservation and / or the recording reservation has been made is a broadcast program corresponding to a broadcast communication cooperation service, and is a broadcast program capable of cooperative operation with a portable terminal device, for portable terminal devices The broadcast cooperation application (terminal side) prepared in the above may also be acquired and started before reaching the broadcast start time of the broadcast program by the same process as described above. Further, as shown in FIG. 16B, a two-dimensional bar code 173e5 or the like indicating information (location information such as a URL) of the acquisition destination of the broadcast cooperation application (terminal side) prepared for the mobile terminal device is displayed on the EPG display screen 173e. , And may prompt the user to download the broadcast cooperation application (terminal side) prepared for the portable terminal device.

  As described above, the broadcast receiving apparatus 100 refers to the acquisition destination information of the broadcast cooperation application included in the EPG information, and starts the acquisition of the broadcast cooperation application before the broadcast start time of the broadcast program. The load of the service provider server 400 storing the broadcast cooperation application can be dispersed. Also, even if the communication speed of the network between the service provider server 400 and the information display terminal 100 is insufficient, the broadcast cooperation application can be effectively used immediately after the start of the broadcast of the broadcast program. become.

  FIG. 17 is an operation sequence diagram showing an example of an acquisition sequence of the broadcast cooperative application in the case of making a viewing reservation and / or a recording reservation of a broadcast program on the EPG display screen 173e.

  During viewing of the digital broadcast service, the main control unit 101 of the broadcast receiving apparatus 100 acquires a program information data string output from the first separation unit 132 (S701). When the user uses the operation terminal to request activation of the EPG screen (S702), the EPG display screen 173e is displayed on the video display unit 173 (S703). When the user selects an arbitrary broadcast program using the operation terminal on the EPG display screen 173e to make a viewing reservation and / or a recording reservation of the broadcast program (S704), the main control unit 101 performs the first separation The program information data string acquired from the unit 132 is confirmed (S705), and the location of the acquisition destination of the broadcast cooperative application linked to the broadcast program for which the viewing reservation and / or recording reservation has been made is further confirmed (S706).

  After the process of S706, the application control unit 161 transmits a transmission request of the broadcast cooperation application to the predetermined service provider server 400 via the LAN communication unit 121 based on the confirmed URL (S707). The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving apparatus 100 as necessary, based on the control of the application management / distribution execution unit 4103, and then performs the processing in the application storage area 4013. Delivery of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S 708). Subsequently, the application control unit 161 caches the predetermined broadcast collaboration application distributed from the service provider server 400 and received via the LAN communication unit 121 in the RAM 104 or the storage 110 (S709).

  According to the transmitting and receiving apparatus 100 of the present embodiment described above, it is possible to execute a function with higher added value.

  Hereinafter, the second embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as in Embodiment 1 unless otherwise noted. Therefore, in the following, the difference between the present embodiment and the first embodiment will be mainly described, and the description of the common points will be omitted as much as possible in order to avoid duplication.

  Although the embodiment in the case of performing the portable information terminal cooperation processing (hereinafter referred to as terminal cooperation) is described also in the first embodiment, the embodiment in further detail will be described.

  When performing portable information terminal cooperation, there are cases where it is desirable to restrict the use of terminal cooperation only to the portable information terminal 700 in the same home as the broadcast receiving apparatus 100 (hereinafter, this restriction is called the same in-house restriction). For example, in an application for using broadcast cooperation (hereinafter referred to as a broadcast cooperation application), the display screen of the broadcast reception apparatus 100 and the display screen of the portable information terminal 700 may be closely related to each other. For example, the user may want the user of the portable information terminal 700 to reliably view the displayed advertisement video.

  In addition, the point which should be considered as a procedure is the judgment of whether the target broadcast cooperation application imposes the same in-home restriction. If it is premised that all broadcast cooperative applications are restricted within the same home, this judgment is unnecessary, but if there is also no restriction, the control information regarding the presence or absence of the same home restriction is broadcast receiver 100 There is a need to get and change the operating procedure. The control information regarding the presence or absence of this restriction may be acquired from the broadcast signal (for example, described as an item of AIT), or may be acquired from a server designated by the broadcast station.

  In the present embodiment, including the above-described procedure, a procedure for ensuring that the portable information terminal 700 exists in the same home as the broadcast receiving apparatus 100 will be described.

  Usually, devices existing in the same home exist on a local network connected to the same router device 210. Therefore, as the portable information terminal 700 is connected to the same local network as the broadcast receiving apparatus 100, it can be determined that the portable information terminal 700 exists in the same home. A known method may be used to determine whether the target device is connected to the local network, and the description is omitted.

  Further, even if the portable information terminal 700 is not on the local network, it can be determined that the portable information terminal 700 exists in the same home by performing direct communication with the broadcast receiving apparatus 100 by NFC, BlueTooth, infrared communication or the like. In this case, the communication for acquiring the broadcast cooperation application or the like may be the direct communication described above or may be mobile telephone communication.

  As described above, a plurality of confirmation methods can be considered for existence in the same home, but which method to use is described in, for example, the AIT and read by the broadcast receiving apparatus 100.

  Furthermore, once it can be confirmed that the portable information terminal 700 exists in the same home, it may be regarded as existing in the same home until the end of the program, or a certain effective time (for example, 10 minutes) is provided. It is also possible to use a method in which it is assumed that they exist in the same house, but if the valid time has passed, they are not considered to exist in the same house unless newly confirmed. This valid time is described in, for example, the AIT and read by the broadcast receiving apparatus 100.

  Further, for example, an event signal is set to the broadcast signal at any time during program progress, and it is confirmed that the portable information terminal 700 exists in the same house every time this event signal is received. You can also.

  Furthermore, it is also possible to combine and use the former two methods.

  Next, a specific procedure for permitting terminal cooperation only to the portable information terminal 700 existing in the same house will be described. In this embodiment, a restriction is provided when the portable information terminal 700 acquires the broadcast cooperation application or when acquiring information used by the broadcast cooperation application (hereinafter, information used by the broadcast cooperation application and the broadcast cooperation application, specifically Although it is HTML documents and streaming video etc., these are collectively called broadcast cooperation information). There are two types of acquisition methods of broadcast cooperation information, communication acquisition acquired from the broadcast station server 300 or the provider server 400, and broadcast acquisition acquired from a broadcast wave. In the case of communication acquisition, there are two types of methods: acquisition after the start of broadcast reception and a method of acquisition before the start of broadcast reception. Furthermore, in the case of communication acquisition, the case is acquired once by the broadcast reception apparatus 100 and acquired by the portable information terminal 700 from the broadcast reception apparatus 100 and when acquired by the portable information terminal 700 directly from the broadcast station server 300 or the operator server 400 There is. Although there are various methods, when viewed from the portable information terminal 700, the method can be roughly divided into two cases: obtaining from the broadcast receiving apparatus 100 and obtaining from the broadcast station server 300 or the carrier server 400.

  In this embodiment, the case where the portable information terminal 700 acquires the broadcast cooperation information from the broadcast receiving apparatus 100 will be described, and in the case of acquiring it from the server, the following embodiment will be described.

  FIG. 18A shows the procedure of this embodiment.

  First, before performing terminal cooperation, each of the portable information terminal 700 and the broadcast receiving apparatus 100 starts a cooperation control application which is an application for controlling terminal cooperation (S10001, S10002). In this state, a terminal cooperation request is issued from the portable information terminal 700 to the broadcast receiving apparatus 100 (S10003). Next, AIT is acquired from the broadcast signal (S10004). Based on the information on this AIT, it is determined whether the target portable information terminal application has the same home restrictions (S10006). If there is a restriction, the process proceeds to S10008, and the first stage of terminal cooperation request is made. Then, the process proceeds to step S10009, and it is determined whether the portable information terminal 700 for which the terminal cooperation request has been made is in the same home as the broadcast receiver 100 (S10009). As a result of the determination, when it is determined that there is not in the same house, a cooperation non-permission response is sent to the cooperation control application on the portable information terminal side, and the process is ended (S10011).

  Here, on the premise that all broadcast collaboration applications have the same in-house restriction, the determination of S10006 is skipped without being skipped. If it is possible to have both the same in-premises restricted application and the in-home restricted application, the determination in step S10006 is performed.

  If it is determined that the portable information terminal 700 is in the same home, or in the case of an application without the same home restriction, the process advances to step S10012 to perform a broadcast cooperation application-related service. In this service (S10012), the broadcast cooperation information distribution request (S10013) from the portable information terminal 700 is processed, and the broadcast cooperation information is distributed to the portable information terminal 700 (S10018). In this broadcast cooperation information, the one received by the broadcast receiving apparatus 100 from the distribution server which is the operator server 300 (S10014, S10015, S10016), the one obtained from the broadcast signal (S10017), and the one stored in the broadcast receiving apparatus 100. There are things that are done. The reception of the broadcast cooperation information by the broadcast receiving apparatus 100 (S10016, S10017) is not limited to the broadcast cooperation information distribution request (S10013) from the portable information terminal 700, but may be acquired autonomously by the broadcast receiving apparatus 100, There may be a case of acquisition based on event occurrence from a broadcast signal. And distribution of the broadcast cooperation information to the portable information terminal 700 (S10018) may also be spontaneous from the broadcast receiving apparatus 100 side.

  After the series of reception (acquisition) of broadcast cooperation information and distribution processing are finished, it is judged whether or not the broadcast receiving apparatus 100 continues to watch the same program (S10019), and if it is not continued, the portable information terminal A cooperation non-permission response is sent to the cooperation control application, and the process ends (S10020).

  If viewing is continued, the procedure returns to S10005, and if there is a home restriction, it is checked whether the portable information terminal 700 is in the same home (S10009), but the effective time preset from the previous confirmation has elapsed Whether or not the broadcast signal or the confirmation request (S10007) from the distribution server has been generated since the previous confirmation (S10008), and if any of the conditions are not met, whether it is in the same house or not The confirmation (S10009) is not performed, and the next broadcast cooperation application related service (S10012) is executed via S10010. Here, although the confirmation request (S10007) from the broadcast signal is described to be acquired from the broadcast cooperation information, here, the event message is also described as being included in the broadcast cooperation information. Furthermore, this confirmation request may be described in the AIT.

  The procedure described above is a loop processing procedure for the broadcast signal, the broadcast receiving apparatus 100, the portable information terminal 700, and the entire distribution server in a section indicated by the arrow in S10022. The confirmation request in S10007 may be at any timing in the loop.

  Furthermore, the authentication information described in the AIT may be incorporated into the authentication key used for authentication at the distribution server (S10015). This makes it possible to confirm that the request is a valid authentication request. In addition, if the authentication information described in the AIT is changed along with the progress of the program, and the distribution server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, the same program can be obtained. You can see that you continue to watch In this case, the AIT information is read and updated as appropriate (S10021). The authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Furthermore, as a method of substantially changing the authentication information, it is possible to use a method of changing the URL of the distribution server itself as the program progresses.

  Thus, while executing the broadcast cooperation application related service (S10012), the portable information terminal 700 receives the broadcast every preset effective time, or every time a broadcast signal or a confirmation request from the distribution server is received. By checking whether or not the apparatus 100 is in the same home, it is possible to execute a broadcast related application that has the same home restriction appropriately. Furthermore, by using the authentication information incorporated in the broadcast signal for authentication in the distribution server, the legitimacy of the distribution request can be secured, and if the authentication information of the broadcast signal is appropriately changed, the same program can be obtained. You can also check that you are continuing to watch

  According to the portable information terminal cooperation technique according to the present embodiment described above, it becomes possible to realize the same in-home restriction for portable information terminals that cooperate with the broadcast receiving apparatus.

  In this embodiment, the case where the portable information terminal 700 acquires broadcast cooperation information from a distribution server will be described.

  FIG. 18B shows the procedure of this embodiment.

  First, before performing terminal cooperation, each of the portable information terminal 700 and the broadcast receiving apparatus 100 starts a cooperation control application which is an application for controlling terminal cooperation (S10101, S10102). In this state, a terminal cooperation request is issued from the portable information terminal 700 to the broadcast receiving apparatus 100 (S10103). Next, AIT is acquired from the broadcast signal (S10104). Information such as a URL related to the distribution server is acquired from the information on the AIT, and the information is transmitted to the portable information terminal 700 (S10105). Next, the broadcast reception apparatus 100 sends a time confirmation request to the distribution server (S10106), and based on this request, the distribution server transmits time information to the broadcast reception apparatus 100 (S10107). In this way, the authentication key can be issued in the latter stage (S10115) according to the time of the distribution server, but may be omitted if there is no problem with the time.

  Thereafter, the loop control indicated by the arrow of S10127 is started.

  First, the portable information terminal 700 issues an authentication key issuance request or a broadcast cooperation information distribution request to the broadcast reception apparatus 100 (S10109). The authentication key is used in the broadcast cooperation information distribution request to the distribution server in the subsequent stage (S10125). The broadcast cooperative distribution request in S10109 is a distribution request for information acquired from the broadcast signal, and corresponds to the procedure of S10126 in the subsequent stage.

  In any case, when the request of S10109 is issued from the portable information terminal, it is determined whether it is a broadcast cooperation application with the same home restriction (S10111), and if there is a restriction, the process proceeds to the next procedure S10112, otherwise the procedure of S10112 is Skip to step S10114. If all the broadcast cooperative applications have the same in-house restriction, the determination in S10111 is not performed, and the process proceeds to S10112. In S10112, it is determined whether the portable information terminal that has issued the request is present in the same house, and if it is not present, terminal cooperation is ended (S10113). If in the same house, the requested procedure, acquisition of broadcast cooperation information from the distribution server (S10125) or acquisition of broadcast cooperation information from the broadcast signal (S10126) is performed. In addition to acquisition from the distribution server, acquisition from the broadcast signal may be performed, so the procedure of S10126 is also described.

  First, an acquisition procedure (S10125) of broadcast cooperation information from the distribution server will be described.

  First, an authentication key requested by the information cooperation terminal 700 is issued from the broadcast receiver 100. At this time, it is assumed that the authentication key is valid only within a predetermined time (for example, 10 minutes), including time information at the time of issuance. The distribution server checks the authentication information including the authentication key within the effective time, and permits the distribution of the broadcast cooperation information if the authentication is OK. Thereafter, the delivery of information is permitted within the effective time, but the delivery is stopped when the effective time has passed. For example, the streaming video can not be viewed after the effective time.

  The preset valid time may be held in the distribution server, or the broadcast receiving apparatus 100 may acquire it from a broadcast signal (for example, AIT) and may incorporate valid time information into the authentication key. Information of the effective time is notified to the portable information terminal 700 in advance, and the issue of the authentication key is requested before the effective time expires. Alternatively, the effective time is managed by the broadcast receiving apparatus 100, and it is confirmed from the broadcast receiving apparatus 100 automatically that the portable information terminal 700 is present after confirming that the portable information terminal 700 is in the same home before the effective time expires. Alternatively, an authentication key may be issued.

  The effective time may be the same in one program or may be changed in accordance with the progress of the program. Moreover, if there is no setting of the effective time, it may be treated that the authentication is effective while watching the program if the authentication is performed once.

  Furthermore, the authentication information described in the AIT may be incorporated into the authentication key used for authentication by the distribution server (S10117). This makes it possible to confirm that the request is a valid authentication request. In addition, if the authentication information described in the AIT is changed along with the progress of the program, and the distribution server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, the same program can be obtained. You can see that you continue to watch In this case, the information on the AIT is read and updated as appropriate (S10124). The authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Furthermore, as a method of substantially changing the authentication information, it is possible to use a method of changing the URL of the distribution server itself as the program progresses. In this case, the URL is changed when the distribution server is the same and the entrance is different, but it may be changed to a new distribution server by changing the broadcast cooperation application or the like. In this case, each time a change is made, procedures of distribution server information transmission (S10105), time confirmation request (S10106), and time information transmission (S10107) are performed.

  Next, a procedure (S10126) for acquiring broadcast cooperation information from a broadcast signal will be described.

  In this case, after confirming that the portable information terminal 700 exists in the same house, the broadcast receiving apparatus 100 acquires broadcast cooperation information from the broadcast signal (S10119), and subsequently distributes the information to the portable information terminal 700. (S10120).

  In addition, when changing broadcast cooperation information with advancing of a program, the notification of a change may be issued from a broadcast signal (S10110), and the notification may be used as a trigger and broadcast cooperation information may be acquired. In this case, if it is acquired from the distribution server, the broadcast receiving apparatus 100 issues an authentication key to the portable information terminal (S10115), and notifies that there is a change notification. If it is within the effective time, issue of the authentication key may be omitted, and only notification of change notification may be made. In the case of acquisition from a broadcast signal, the broadcast receiving apparatus 100 acquires information (S10119), and distributes the information to a portable information terminal (S10120). In addition, in the case of acquisition from a broadcast signal, it may be confirmed that the portable information terminal 700 is in the same house every change notification, and as in the second embodiment, the confirmation is omitted within the effective time. It does not matter. Here, the change notification (S10110) from the broadcast signal is described as being acquired from the broadcast cooperation information, but here, the event message is also described as being included in the broadcast cooperation information. Furthermore, this change notification may be described in the AIT.

  After processing of reception (acquisition) and distribution of a series of broadcast cooperation information is completed, it is judged whether the broadcast receiving apparatus 100 continues to watch the same program (S10121), and if not continued, the portable information terminal side A cooperation non-permission response is sent to the cooperation control application, and the process ends (S10123). If viewing and listening is continued, the process returns to S10108, and the loop process S10127 is continued.

  As described above, by including the time information in the authentication key used to authenticate the distribution server and managing the effective time, it can be periodically confirmed that the portable information terminal 700 is in the same home as the broadcast receiving apparatus 100. It is possible to appropriately execute the broadcast cooperation application that has the same in-home restriction. Furthermore, by using the authentication information incorporated in the broadcast signal for authentication in the distribution server, the legitimacy of the distribution request can be secured, and if the authentication information of the broadcast signal is appropriately changed, the same program can be obtained. You can also check that you are continuing to watch

  According to the portable information terminal cooperation technique according to the present embodiment described above, even when the portable information terminal cooperating with the broadcast receiving apparatus acquires the broadcast cooperation information from the distribution server, it is possible to realize the same home restriction .

  In the second and third embodiments, the procedure for realizing the same in-home restriction in the terminal cooperation has been described, but the use from outside the home may be permitted depending on the broadcast cooperation application. Such a case will be described in this embodiment. For example, when a program such as television shopping itself is a publicity / advertisement, it is desirable for the broadcaster to be able to use the broadcast cooperation application regardless of the inside of the home. In the case of such a program, once registered in the broadcast receiving apparatus 100, the use of the broadcast cooperation application may be permitted regardless of whether the portable information terminal 700 is in the home. In this case, if there is a broadcast cooperation application in which the broadcast video itself is used as streaming data and is distributed from the broadcast receiving apparatus 100 to the portable information terminal 700 via the Internet, the convenience is further enhanced. The streaming data may be encrypted by the broadcast receiving apparatus 100 for copyright protection. It is described in the data (for example, AIT etc.) in the broadcast signal whether the broadcast cooperation application permits the use from outside the home including the delivery of the broadcast video outside the home.

  A specific procedure is shown in FIG. 18C. Since a part of the procedure is common to the second and third embodiments, the description of the same parts as those in the second and third embodiments will be omitted. If there is a terminal cooperation request from outside the home (S10203), the broadcast receiving apparatus 100 confirms that the request source is a registered portable information terminal if the application is permitted to use outside the home ( In S10205), the cooperation is permitted. Here, if necessary, authentication may be performed between the portable information terminal 700 and the broadcast receiving apparatus 100 in order to protect the copyright of broadcast video and broadcast cooperation information (S10207). At that time, the authentication may be authentication in the distribution server (S10207). Information on the necessity of copyright protection and information on an authentication method of copyright protection are acquired from a broadcast signal (for example, those described in AIT), and control according to the information is performed. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving apparatus 100 is followed. For example, predetermined copyright protection processing may be performed. In addition, when such information is not stored in the broadcast signal, it may be determined in advance that the copyright protection process is not performed in the broadcast receiving apparatus 100.

  The following is a specific example of certification for copyright protection. The following authentication may be performed only once. Alternatively, a plurality of authentications exemplified below may be performed in combination. Further, the authentication exemplified below and other authentication processing not exemplified below may be performed in combination.

[Authentication by ID and Password]
When registering the portable information terminal 700 in the broadcast receiving apparatus 100, an ID and a password are issued, and the broadcast receiving apparatus 100 permits cooperation by confirming the ID and the password.

Use encryption key
In addition to the authentication based on the above ID and password, an encryption key for decrypting encrypted video data and the like is transmitted from the broadcast receiving apparatus 100 to the portable information terminal. This encryption key may be acquired from a broadcast signal (for example, described in the AIT).

[Use of distribution server]
A method of issuing an encryption key for decrypting encrypted video data and the like from a distribution server. The portable information terminal 700 transmits the ID and the password to the distribution server, and acquires the encryption key. In this case, location information (specifically, a URL) of the distribution server is acquired from a broadcast signal (for example, described in the AIT), and the location information is transmitted from the broadcast receiving apparatus 100 to the portable information terminal 700, More secure. If the portable information terminal 700 can not obtain the encryption key, it can not decode the video etc., therefore, by requesting authentication from the broadcast receiving apparatus 100 by the distribution server, it may be possible to authenticate writing protection, or the portable information terminal The authentication may be completed by notifying the broadcast receiving apparatus 100 that the encryption key has been acquired from 700. The distribution server may be charged.

Mutual authentication of encryption keys
The encryption key possessed by each of the broadcast receiving apparatus 100 and the portable information terminal 700 is mutually authenticated, and confirmation is made to be an authentication of copyright protection.

  If the information stored in the broadcast signal indicates that copyright protection by a predetermined method is necessary, and if the copyright protection authentication can not be performed by the predetermined method, terminal cooperation is not permitted. In addition, even when the broadcast signal is not specified and authentication is performed by the predetermined method of the broadcast receiving apparatus 100, the terminal cooperation is not permitted if the copyright protection authentication can not be performed by the predetermined method.

  If the terminal cooperation is permitted, then it is not confirmed whether the portable information terminal 700 exists in the same house, and a request from the portable information terminal 700 (S10211), autonomous control of the broadcast receiving apparatus 100, broadcast signal In accordance with the request from (S10210), distribution of the broadcast cooperation information (S10217) and issuance of an authentication key for the distribution server (S10212) are performed to the portable information terminal 700. In this case, control for setting the effective time may not be performed. The portable information terminal 700 outside the home acquires the broadcast cooperation information from the distribution receiving apparatus 100 or the distribution server using the issued authentication key (S10215). Also, the authentication information (for example, described in the AIT) acquired from the broadcast signal is incorporated into the authentication key issued by the broadcast receiving apparatus 100, and the distribution server is an authentication key incorporating the authentication information acquired from the broadcast signal. If access is permitted, it is possible to achieve more appropriate use outside the home.

  Furthermore, when discounting as a program viewing premium, it may be preferable not to allow unlimited use of the broadcast cooperation application. In such a case, authentication is performed in the same home with a portable information terminal at one time. It is preferable to use a method that permits the use of the distribution server even if it is not in the same house after that. In this case, the portable information terminal 700 may not be registered in the broadcast receiving apparatus 100.

  A specific procedure in this case is shown in FIG. 18D. Since a part of the procedure is common to that of FIG. 18C, the description of the overlapping part is omitted. First, while the portable information terminal 700 is in the same house as the broadcast receiving apparatus 100, the portable information terminal 700 makes a terminal cooperation request to the broadcast receiving apparatus 100, and the broadcast receiving apparatus 100 is in the same house as the portable information terminal 700. After confirming that it is in (S10305), cooperation is permitted. Here, if necessary, authentication may be performed between the portable information terminal 700 and the broadcast receiving apparatus 100 in order to protect the copyright of broadcast video and broadcast cooperation information (S10307). At that time, the authentication may be authentication in an external distribution server. Information on the necessity of copyright protection and information on an authentication method of copyright protection are acquired from a broadcast signal (for example, those described in AIT), and control according to the information is performed. If such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving apparatus 100 is followed. For example, predetermined copyright protection processing may be performed. In addition, when such information is not stored in the broadcast signal, it may be determined in advance that the copyright protection process is not performed in the broadcast receiving apparatus 100.

  The following is a specific example of certification for copyright protection. The following authentication may be performed only once. Alternatively, a plurality of authentications exemplified below may be performed in combination. Further, the authentication exemplified below and other authentication processing not exemplified below may be performed in combination.

Use encryption key
While the portable information terminal 700 is in the same home, an encryption key for decrypting encrypted video data and the like is transmitted from the broadcast receiving apparatus 100 to the portable information terminal. This encryption key may be acquired from a broadcast signal (for example, described in the AIT). Authentication is performed by delivering this encryption key in the same home. Furthermore, if the encryption key can not be acquired from the broadcast signal at a certain point in the program, and the delivery of the encryption key to the portable information terminal 700 is limited to the same home, it must be in the same home at that time, A restriction can be set and can also be used to give a premium to viewing.

[Use of distribution server]
A method of issuing an encryption key for decrypting encrypted video data and the like from a distribution server. The portable information terminal 700 transmits the ID and the password to the distribution server, and acquires the encryption key. In this case, location information (specifically, a URL) of the distribution server is acquired from a broadcast signal (for example, described in the AIT), and the location information is transmitted from the broadcast receiving apparatus 100 to the portable information terminal 700, More secure. If the portable information terminal 700 can not obtain the encryption key, it can not decode the video etc., therefore, by requesting authentication from the broadcast receiving apparatus 100 by the distribution server, it may be possible to authenticate writing protection, or the portable information terminal The authentication may be completed by notifying the broadcast receiving apparatus 100 that the encryption key has been acquired from 700. Access to the distribution server may be performed at home or outside the home, but the location information of the distribution server can not be acquired from the broadcast signal unless there is a program at a certain point of time. By limiting the delivery to the same home, it is possible to place a restriction that the user must be in the same home at that time, and can also be used to give a premium to viewing. The distribution server may be charged.

Mutual authentication of encryption keys
The encryption key possessed by each of the broadcast receiving apparatus 100 and the portable information terminal 700 is mutually authenticated, and confirmation is made to be an authentication of copyright protection. This authentication may be performed at home or outside the home.

  If the information stored in the broadcast signal indicates that copyright protection by a predetermined method is necessary, and if the copyright protection authentication can not be performed by the predetermined method, terminal cooperation is not permitted. In addition, even when the broadcast signal is not specified and authentication is performed by the predetermined method of the broadcast receiver 100, if the authentication of copyright protection can not be performed by the predetermined method, terminal cooperation is not permitted. The procedure after the terminal cooperation is permitted is the same as the procedure in FIG.

  According to the mobile information terminal cooperation technology according to the present embodiment described above, it is possible to realize the use from outside the home while paying attention to copyright protection for the mobile information terminal that cooperates with the broadcast receiving apparatus.

  In an actual use situation, it is more desirable to simply know the presence or absence of a terminal cooperation application by a program and which terminal cooperation application can be used. In this embodiment, a method of displaying the availability of the terminal cooperation application will be described. The terminal cooperation application refers to a broadcast cooperation application used in terminal cooperation.

  FIG. 19A is an example of the launcher screen (173b11) of the broadcast cooperation application when there is a terminal cooperation application. The broadcast cooperation application is displayed with a framed character icon. The broadcast cooperation application (173b12-173b14) for the broadcast receiving apparatus 100 which cooperated with the program in process of viewing and the broadcast cooperation application (173b15-173b17) for portable information terminals are displayed. In this example, the thickness of the frame surrounding the character string and the color in the frame indicate the status of the application. The main application A, B (173b12, 173b13) and the terminal application A, B (173b15, 173b16) are available, and the main application C (173b14), the terminal application C (173b17) are unavailable. . The state in which the terminal application can not be used means that none of the portable information terminals 700 in the state capable of communicating with the broadcast receiving apparatus 100 has a function to execute the application.

  FIG. 19B is a screen after the terminal application A is selected in FIG. 19A. The state of each portable information terminal 700 related to the terminal application A is shown. The portable information terminal displayed on this screen is a terminal that has been registered in the past with the broadcast receiving apparatus 100.

  The portable terminal 1 (173b22) and the portable terminal 2 (173b23) whose border lines of the icon are solid lines are in a communicable state with the broadcast receiving apparatus 100, and the portable terminals 3 (173b24) whose border lines are dotted lines And the portable terminal 4 (173 b 25) are not in a state capable of communicating with the broadcast receiving apparatus 100. In addition, the portable terminal 1 (173b22) and the portable terminal 3 (173b24) in which the inside of the frame of the icon is white have the function of executing the terminal application A, and the portable terminal 2 (173b23) and the portable terminal 4 in which the inside of the frame is gray. (173b25) indicates that there is no function to execute the terminal application A. Furthermore, if an application is already running on the terminal, an icon of a design representing that may be used.

  In addition, since the icon is more visually comprehensible when a pattern is used, an example is shown below.

  FIG. 19C is an example of a launcher screen (173b31) showing a list of broadcast cooperation applications. Icons are shown for each type of portable information terminal 700 in addition to the broadcast receiving apparatus 100. 173b32 and 173b33 are icons indicating the broadcast receiving apparatus 100, 173b34 and 173b35 are icons indicating the smart phone type portable information terminal 700, and 173b36 are icons showing the head mounted display type portable information terminal 700. Each application is for a device indicated by an icon.

  In FIG. 19C, when the application can not be used, a mark (in the case of this case, a circle with a hatched mark) indicating that it can not be used is superimposed on the pattern of the device. Further, with regard to the broadcast receiving apparatus 100, if the application is already being executed, a mark (in the case of the present, a point on a circle) may be superimposed and displayed. By this display, it is possible to prevent the useless operation of advancing the procedure of the launcher even though it is already executed. In the case of the portable information terminal 700, it is also possible to display a mark indicating that the application is being executed when all the terminals capable of executing the application are in communication and in a state of being communicable with the broadcast receiving apparatus.

  FIG. 19D is a screen (173b41) after the application C (173b34) is selected in FIG. 19C. The state of the portable information terminal 700 of the type corresponding to the application C is shown. In this screen, when the portable information terminal 700 does not have the function to execute the broadcast cooperation application, when the portable information terminal 700 is not in a communicable state with the broadcast receiving apparatus 100, and when the broadcast cooperation application is already being executed, Display a mark on top of the icon. In this example, a circle with oblique lines (173b44, 173b46) if it has no execution function, an exclamation mark (173b45, 173b46) with triangles if it is not in the communicable state, and a circle if it is already running. The mark (173b43) is displayed.

  Furthermore, it is desirable that there is a display method that shows that there is a broadcast cooperation application when the situation changes, even without activating the launcher every time. For example, when the power is turned on, the channel is changed, the beginning of the program, or the middle of the program, there is a change in the communication state between the broadcast receiving apparatus 100 and the portable information terminal 700. In this case, when the execution status of the application changes, the icon is displayed for a predetermined time, and the state at that time is displayed.

  FIG. 19E shows an example in that case. When an icon indicating the type of each device is displayed, it indicates that there is a broadcast cooperation application corresponding to the type of device. In this case, a circle and a hatched mark indicate that there is nothing that can execute the application on the type of device that is in the usable state. A circle with a dot indicates that the application is running on all devices of that type that are available.

  FIG. 19F shows a display screen (10401) on the portable information terminal 700. When requesting the terminal cooperation from the portable information terminal 700, it is convenient for the user to know which broadcast cooperation application can be used by which broadcast receiving apparatus 100 in the list. FIG. 19F shows an example of the list (10402). This table indicates which broadcast receiving apparatus 100 in the home can use the broadcast cooperation application corresponding to the program to be checked. In addition, when the status of each broadcast receiving apparatus 100 is also displayed, the convenience is particularly enhanced when used from outside the home. In this example, a display example is shown such as receiving the program, receiving another program, vacant, or having another program reserved (when recording of another program is reserved from the middle of a program). Here, when there are a plurality of tuners in the broadcast receiving apparatus 100, the convenience is further enhanced if the state is displayed for each of the plurality of tuners. In Table 10202, branch numbers indicate the distinction of tuners in the same apparatus. For example, the receiving device B-1 and the receiving device B-2 are tuners in the same broadcast receiving device 100. In the case of terminal cooperation, if it is possible to receive broadcast video and audio as streaming data, it is not necessary to use the video unit of the broadcast receiving apparatus 100, and if the tuner in the broadcast receiving apparatus 100 can be used, broadcast can be used. Therefore, it is useful to know the usage status of each tuner.

  In addition, in order to perform the display described in this embodiment, information of whether the application is compatible with the broadcast receiving apparatus 100 or the type of portable information terminal 700 is compatible with each broadcast cooperation application. There must be. Further, the broadcast receiving apparatus 100 and the portable information terminal 700 need information for executing the corresponding application. These pieces of information can be acquired by the broadcast receiving apparatus 100 by describing them in the AIT, for example.

  According to the mobile information terminal cooperation technology according to the present embodiment described above, it is possible to use the broadcast cooperation service with higher convenience by displaying information on the broadcast cooperation application, the broadcast receiving apparatus 100, and the mobile information terminal 700. It becomes.

  The following describes the broadcast receiving apparatus 100 according to the sixth embodiment of the present invention. The configurations, effects, and the like in the present embodiment are the same as in the first to fifth embodiments unless otherwise noted. Therefore, in the following, the difference between the present embodiment and the first to fifth embodiments will be mainly described, and the description of the common points will be omitted as much as possible in order to avoid duplication.

  In the above-described first to fifth embodiments, the start of the broadcast cooperation application has been mainly described. However, the broadcast cooperation application is configured of, for example, one or more HTML documents as described above. That is, it is possible to make a transition between HTML documents by a link.

  FIG. 20 shows the concept of transition of the broadcast cooperation application and the HTML document. (A) of FIG. 20 illustrates an example of transition between documents within the application boundary 20201 of the broadcast cooperation application 20110 and the application boundary 20201.

  In (a) of FIG. 20, from the state where the broadcast receiving apparatus 100 receives the video by the broadcast signal as described above, or the state (20000) where the data broadcasting screen information is displayed by executing the BML document, App1, which is a broadcast cooperation application 20110, is activated. The activation of the broadcast cooperation application 20110 is an automatic activation by the AIT or an instruction of the user. When the broadcast cooperation application 201 10 is activated, the first HTML document 20111 which is an entry document is executed.

  App1, which is the broadcast cooperation application 20110, is composed of HTML1 to HTML4 which are four HTML documents 20111 to 12014 shown. In (a), the application boundary 20201 of the broadcast cooperation application 20110 is configured by the four HTML documents 20111 to 12014. The application boundary indicates the boundary of the transitionable area, and is set in the AIT as a collection of one or more areas. Here, the area is an HTML document.

  In each HTML document, a link to another HTML document is arranged, and the link enables transition between the HTML documents. Solid arrows indicate transition links. The dashed arrows show examples of the execution of the transition. In the example of (a), bi-directional transition is possible between all HTML documents. Without being limited thereto, there may be a case where only transition to a specific HTML document is possible, or a case where only one direction of transition is possible.

  The application boundary may be changed during application execution. Therefore, the HTML document that was within the range of the application boundary at the start of execution may be out of the range of the application boundary by changing the application boundary on the way.

  FIG. 20B shows an example of an application boundary 20202 after the application boundary has been changed from the state of FIG. 20A and a transition related to the application boundary 20202. The changed application boundary 20202 is composed of two documents, an HTML document 20111 and an HTML document 20112. In the application boundary 20202, mutual transition is possible by bi-directional link between two documents.

  For example, during execution of the HTML document 20113 of (a) of FIG. 20, the application boundary 20201 is dynamically changed to the application boundary 20202 of (b). In this case, the HTML document 20113 is out of the range of the application boundary 20202.

  As an example of the dynamic change of the application boundary, there is a change of the information of the content of AIT of the broadcast signal such that the broadcast station changes the application boundary according to the content of the broadcast.

  Since the change of the application boundary as described above is not intended by the user, the user does not know the timing of the change or the state of the application boundary after the change. Therefore, the broadcast receiving apparatus 100 of the sixth embodiment has a function of controlling the operation as follows.

  FIG. 21 is a flowchart of the operation sequence of the broadcast receiving apparatus 100 according to the sixth embodiment. This flowchart shows the operation when executing the HTML document (for example, HTML1 to HTML4) of the broadcast cooperative application 20110 of FIG.

  When executing the HTML document of the broadcast cooperation application, the broadcast receiving apparatus 100 first reads the HTML document (S20001), and executes the read HTML document (S20002). That is, step S20002 is execution of a broadcast cooperation application, and is the same operation | movement as Example 1-5 mentioned above.

  Step S20002 and subsequent steps show features of the operation of the broadcast receiving apparatus 100 according to the sixth embodiment. After S20002, the broadcast receiving apparatus 100 according to the sixth embodiment performs processing to confirm the presence or absence of interrupt processing (S20003). The interrupt processing here is termination of the broadcast cooperation application, transition to another HTML document within the application boundary, execution of the other broadcast cooperation application, or the like. If there is an interrupt process (S20003-Yes), the broadcast receiving apparatus 100 ends the process of FIG. 21 and starts an operation corresponding to the interrupt process. Here, the description of the operation corresponding to the interrupt processing is omitted.

  When there is no interrupt processing (S20003-No), the broadcast receiving apparatus 100 checks whether the HTML document being executed is within the range of the application boundary (S20004). If the HTML document being executed is not within the range of the application boundary, in other words, if it is outside the range of the application boundary (S20004-No), the broadcast receiving apparatus 100 does not fall within the range of the application boundary on the video display unit 173. A mark 20200 is displayed to indicate that it is out of range, in other words (S20005).

  When it is within the range of the application boundary in the step S20004 (S20004-Yes), the mark 20200 is not displayed (S20008), and the process returns to the step S20003. During the execution of the HTML document of the broadcast cooperation application 201 10, the broadcast reception apparatus 100 continuously and repeatedly executes the process of the check of S20004 by the loop returning to S20003.

  The process of S20004 may be a periodic process, for example, a process that is performed once in several seconds, or may be a process that is performed when the HTML document is updated.

  FIG. 22 shows a display example of the mark according to S20005. FIG. 22 shows the broadcast cooperation application section 173c1, which is a weather forecast in this example, overlaid on the broadcast program screen 173c by executing the HTML document of the broadcast cooperation application. These are displayed by the process of reading the HTML document (S20001) and the process of execution (S20002).

  Then, the broadcast receiving apparatus 100 indicates that the HTML document of the broadcast collaboration application being executed is out of the range of the application boundary in the broadcast program screen 173c of the video display unit 173 of FIG. 22 by the process of S20005 of FIG. The mark 20200 is displayed. In this example, a mark 20200 indicated by a circle x is displayed by OSD or the like at the lower right corner of the screen. By viewing the display of the mark 20200, the user can know that the HTML document of the broadcast collaboration application being executed is out of the application boundary.

  Not only the display of the mark 20200 or the icon or the image but also the display of a message of characters or the like may be used. An example of the message is "out of application boundary" or the like. It may be a display of both a mark and a message.

  In the case of the broadcast cooperation application, the HTML document often displays information related to the broadcast video, and there is a possibility that the content of the HTML document deviated from the application boundary is less related to the broadcast video. Continuing to execute such HTML documents may not be beneficial to the user. Thus, in the sixth embodiment, the state is notified to the user by the above mark and transmitted, and control is performed to transition from outside the application boundary to the HTML document in the application boundary.

  In FIG. 21, in the sixth embodiment, after step S20005 of mark display, step S20006 of detecting whether the mark is selected by the user is provided. In this step, it is detected that the user has selected the mark 20200 by clicking with a cursor or the like on the screen of FIG. 22, or a predetermined user operation corresponding to the selection of the mark. At this time, a message for prompting a predetermined user operation may be displayed on the screen. An example of the message is "Please click to return to the application within the application boundary." "Please press the ○○ button to return."

  When the above mark is selected (S20006-Yes), the broadcast receiving apparatus 100 is an HTML document that has been executed before the currently executed HTML document regarding the broadcast cooperation application, and within the current application boundary. A transition is made to the included HTML document (S20007). If the mark is not selected (S20006-No), the process returns to step S20003.

  The processing of transition of S20007 is realized by, for example, an instruction to make transition to a predetermined HTML document, in other words, information of designation of the HTML document of transition destination, or the like. The instruction of this transition is described by, for example, AIT. At step S20007, transition is made in accordance with the instruction of the transition to end the present processing, and the present processing is started again. At step S20002, the HTML document of the transition destination is executed.

  In the process of S20007, when there are a plurality of candidates for the transition destination HTML document, the transition destination HTML document is determined, for example, by the following method. In the first method, among the candidates, the HTML document executed last is the transition destination. In the second method, among the candidates, the HTML document executed first, for example, an entry document, is the transition destination.

  Further, when transitioning from the state outside the application boundary in S20007 and returning to the state of display by execution of another HTML document, a mark, a message or the like representing that may be displayed on the screen (S20009). An example of the message in this case is "Return to display of application in application boundary."

  FIG. 23 shows an example of the operation of the above-mentioned transition and the like corresponding to the example of the broadcast cooperation application of FIG. 20 in the broadcast receiving apparatus 100 of the sixth embodiment. The horizontal axis shows time. In the vertical direction, the AIT of broadcast waves, application boundaries, user operations, executable documents, and displays are shown in association with one another.

  At time t1, the AIT of the broadcast wave indicates that the broadcast cooperative application, for example, App1 in (a) of FIG. 20 has been activated. When the broadcast cooperation application is activated, the entry document HTML1 is executed, and the screen is displayed in HTML1. At this time, the application boundary 20201 of the broadcast cooperation application is HTML1 to HTML4.

  At time t2, a document transition instruction 20221 is issued by a user operation. As a result, the transition from HTML 1 to HTML 2 is made, and the state of display by HTML 2 is established. At time t3, a transition instruction 20222 is issued by a user operation. As a result, the transition from HTML 2 to HTML 3 is made, and the state of display by HTML 3 is established.

  At time t4, it is indicated that the application boundary is dynamically changed during the execution of the broadcast cooperation application, that is, while the broadcast program is being broadcast. That is, the application boundary 20201 is changed to the application boundary 20202. This change is described, for example, in AIT. The application boundary 20202 is covered by two documents of HTML1 and HTML2.

  At t4, the document being executed is HTML3 and HTML3 is not included within the scope of the application boundary 20202. The broadcast receiving apparatus 100 detects that the HTML 3 is out of the range of the application boundary 20202 (S20004 above), and displays the mark 20200 on the screen from t4 (20230). This notifies the user that the HTML 3 being executed is out of the range of the current application boundary 20202.

  At time t5, the user selects the mark 20200 (20223). As a result, the broadcast receiving apparatus 100 stops displaying the mark 20200, and transitions to an HTML document that is an HTML document that has been executed prior to the currently executing HTML 3 and that is included in the current application boundary 20202. Here, since there are two documents (HTML 1 and HTML 2) as candidates of transition destinations corresponding to the condition, they are selected from them. For example, according to the above first method, the HTML document executed last, that is, HTML 2 is determined as the transition destination. This returns to the state of display by execution of HTML2. In this case, the user sees the HTML2 state that he had just seen, so it is easy to recognize the situation.

  When the second method is used, the mark selection (20223) determines HTML1 which is an entry document executed first as a transition destination. This returns to the state of display by execution of HTML1. In this case, the user is likely to recognize the situation because the user is again looking at the HTML1 state that he first saw at startup.

  At time t6, from the state of HTML2, a termination instruction (20224) of the broadcast cooperation application by a user operation is performed, whereby the broadcast cooperation application is ended. Of course, the program may be used continuously, for example, transition to another HTML document without ending the broadcast cooperation application.

  In the above configuration, the selection of the mark by the user operation is adopted as a means for causing transition to the HTML document within the range and returning the display state at the time of changing the application boundary. For example, the above transition may be performed by user operation of a predetermined button having a function corresponding to the above-described means provided in the remote control of the broadcast receiving apparatus 100.

  Although the above-mentioned composition explained the case where one broadcast cooperation application was started, it is possible similarly, about the case where a plurality of broadcast cooperation applications are started simultaneously. When a plurality of broadcast cooperation applications are activated at the same time, a mark, a message, and the like on the screen are displayed, for example, in the vicinity of a display corresponding to an application or the like out of application boundaries among the plurality of broadcast cooperation applications. .

  In the above configuration, the document of the transition destination at the time of control to return to the state in the application boundary may be designated by information such as AIT. Also, in the above configuration, a control method such as returning to the document of the immediately preceding execution as a transition destination or returning to the entry document, or a control method of transitioning or automatically transitioning based on the selection of the mark. Is preset as a specification of the broadcast receiving apparatus 100. The control method may be designated by information such as AIT. In that case, the broadcast receiving apparatus 100 refers to the information such as the AIT, and recognizes the document of the transition destination and the control method. Further, with regard to the above control method, the setting of selection by the user with respect to the broadcast receiving apparatus 100 may be enabled.

  In the above configuration, when a new HTML document is added within the range of the application boundary after the change due to the dynamic change of the application boundary, the added document may be set as the candidate of the transition destination. FIG. 24 shows an application boundary 20203 which is an example after such a change. In the application boundary 20203, HTML5 which is an HTML document 20115 is added to HTML1 and HTML2. The broadcast receiving apparatus 100 may use HTML 5 as a transition destination, for example, when returning from the state of HTML 3 which is out of the range of the application boundary 20203. In this case, the user sees the state of display by the new HTML 5 and is easy to recognize the state of the change of the application boundary.

  As described above, according to the broadcast receiving apparatus 100 of the sixth embodiment, by displaying the mark 20200 on the video display unit 173, the user can know that the HTML document in execution of the broadcast cooperation application is out of the range of the application boundary. I can know. In addition, it is possible to return to the state by the HTML document within the range of the application boundary by a simple operation such as selection of the displayed mark or button operation of the remote control, which is convenient for the user.

  In another embodiment, if the application boundary is out of the above-mentioned condition, control is made not to display the mark, but to immediately transition from the HTML document under execution to another HTML document corresponding to the above condition. Good. That is, the user operation may be omitted and the state of the previous HTML document may be automatically restored. In the case of this embodiment, the control is a flow in which S20005 and S20006 are eliminated in FIG. In this case, the broadcast receiving apparatus 100 may display, on the screen, a mark or a message representing the control content, for example, “Because this is an application outside the boundary, the display has returned to the application within the boundary.” (S20009). In the case of this embodiment, since it is not necessary to select a mark or the like, it is less time consuming for the user.

  As another embodiment, information including a list of documents (for example, HTML 1 and HTML 2) as candidates for the transition destination is displayed on the screen, the transition destination is selected from the list by the user operation, and the selected document is selected. It may be controlled to return to the state of display. FIG. 25 shows an example of a display screen according to this embodiment. When the application boundary is not reached, information such as 20300 is displayed on a part of the screen. 20300 includes messages and the above list. An example of the message is "Outside application boundary. Please select a destination to return." The list displays HTML1 and HTML2 which are documents included in the range of the current application boundary 20202 of App 1 which is a broadcast cooperative application as transition destination candidates, and accepts an operation of selecting a document of the transition destination by the user. The user can return to the desired display state by selecting a document from the list.
