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.

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 142 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 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 of 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, in a state where the portable information terminal 700 is in the same home 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 home 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 sixth embodiment of the present invention will be described below. 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.

  In the present embodiment, the operation of the broadcast reception application 100 based on the AIT transmitted on the broadcast wave based on the AIT, particularly in the following cases, will be described by way of an example. In this case, the broadcast cooperation application is the broadcast management application, and the information on the PMT and the information such as the application control code 903 of the AIT and the activation priority 907 (FIG. 6) enables the broadcast management application which is the broadcast cooperation application. This is the case where the application is prescribed and instructed to be preferentially started automatically. Hereinafter, the broadcast managed application may be referred to as a “broadcast managed application”.

  The broadcast receiving apparatus 100 according to the sixth embodiment has a function of controlling the start processing of the broadcast cooperative application for which the above-described automatic start is designated in the digital broadcast service, in accordance with the selection by the user. The broadcast receiving apparatus 100 according to the sixth embodiment does not automatically start the broadcast cooperative application unconditionally when there is a rule or instruction of the above-described automatic start, and does not satisfy the following conditions (1) to (3). Control automatic startup only if applicable. (1) When automatic start is set to be permitted in the user settings of the broadcast receiving apparatus. (2) When the user who possesses the predetermined terminal linked to the broadcast receiving apparatus is viewing, in other words, when the automatic startup is set to be permitted in the user setting of the linked terminal. (3) When confirmation of activation is executed each time to the user and the confirmation is affirmed.

  FIG. 20 shows a system configuration including the broadcast receiving apparatus 100 of the sixth embodiment and an application example. The broadcast receiving apparatus 100 receives a broadcast wave from the broadcast station server 300 via the radio wave tower 300t, and separates a video of a broadcast program and information such as AIT. The broadcast receiving apparatus 100 appropriately acquires the broadcast cooperation application from the service provider server 400 based on the information such as the AIT. The AIT may include information for instructing automatic activation of a broadcast cooperation application linked to a broadcast program.

  There are one or more portable information terminals 700 that perform terminal cooperation with the broadcast receiving apparatus 100. For example, one broadcast receiving apparatus 100 can cooperate with each of the portable information terminals 700 of two users and is shared. For example, there are a terminal A owned by the user A and a terminal B owned by the user B. Not limited to this, one user may use a plurality of mobile information terminals 700.

  The broadcast receiving apparatus 100 according to the sixth embodiment includes an application activation control unit 2000 including a user selection unit 2001. The user selection unit 2001 is a unit that selects whether or not to accept the start and execution of the broadcast cooperative application based on the operation of the user of the broadcast receiving apparatus 100 and the portable information terminal 700. The user selection unit 2001 includes, for example, an instruction input unit and a user setting unit in the broadcast receiving apparatus 100 and the portable information terminal 700. When the automatic activation of the broadcast cooperation application is instructed by the AIT, the application activation control unit 2000 performs the broadcast according to the selection by the user and the user selection unit 2001 regarding whether or not to accept the permission of the activation and execution of the broadcast cooperation application. Control launch of linked applications.

[In case of automatic start of broadcast managed app]
In the sixth embodiment, first, the broadcast receiving apparatus 100 appropriately confirms information such as the PMT and the AIT and activates the broadcast managed application when the broadcast managed application is defined to be automatically activated in priority. The operation sequence of is the same as the description using FIG. 7A of the first embodiment. In the example of FIG. 7A, whether the target broadcast managed application can be executed in the broadcast receiving apparatus 100 is confirmed by confirming the application profile 904 of the AIT (S105). If the executability is confirmed, the broadcast managed application is always activated automatically regardless of the selection of the user of the broadcast receiving apparatus 100.

  However, for example, the possibility that the user of the broadcast receiving apparatus 100 does not want to automatically start the broadcast managed application should be considered, for example, because he / she wants to concentrate on viewing a broadcast program. The broadcast receiving apparatus 100 according to the sixth embodiment has an application activation control unit 2000 as a control function in consideration of this possibility. That is, when the broadcast receiving apparatus 100 according to the sixth embodiment receives an instruction to automatically start broadcast managed application priority based on the information such as the PMT and the AIT, and when execution of the broadcast managed application based on the information such as the AIT is confirmed. Also in this case, the activation of the application is controlled in accordance with the user's selection of whether or not to activate. Hereinafter, an example in which whether to automatically start the broadcast managed application is controlled will be described.

[Operation sequence (1) at start of broadcast managed application]
FIG. 21 illustrates, as a first configuration example and processing example of the broadcast receiving apparatus 100 according to the sixth embodiment, activation of a broadcast cooperation application in the case where a broadcast managed application that is a broadcast cooperation application is defined to be activated preferentially. An example of the operation sequence of the hour is shown. FIG. 21 shows a series of flow from when the broadcast receiving apparatus 100 appropriately checks PMT and AIT information, and further controls whether to automatically start a predetermined broadcast cooperative application according to the user's selection. The first configuration example uses user settings in the broadcast receiving apparatus 100 as the user selection unit 2000.

  In FIG. 21, the broadcast receiving apparatus 100 performs tuning processing of a channel desired by the user by the tuner / demodulation unit 131 of FIG. 2A to acquire a TS. Next, the broadcast receiving apparatus 100 acquires the PMT data string separated by the first separation unit 132 by the main control unit 101 (S1101), and confirms the activation priority described in the acquired PMT (S1102). The broadcast receiving apparatus 100 confirms that the activation priority of the broadcast managed application that is the broadcast cooperation application is high in the processing of S1101 and S1102.

  After the confirmation, the broadcast receiving apparatus 100 acquires the AIT data string separated by the first separation part 132 by the application control unit 161 (S1103), and confirms the application control code 903 of the acquired AIT data string (S1104) . When the application control code 903 is "automatic start" in the processing of S1103, S1104, that is, when the automatic start of the broadcast cooperation application is designated, the broadcast receiving apparatus 100 further performs the application of the acquired AIT data string. The profile 904 is confirmed (S1105).

  In S1105, the broadcast reception apparatus 100 confirms that the broadcast cooperation application designated by the AIT can be executed by the broadcast reception apparatus 100 by confirming the information of the application profile 904. When the executability is confirmed, the broadcast receiving apparatus 100 further refers to the operation setting value stored in the storage unit 110 by the application control unit 161. Thereby, the broadcast receiving apparatus 100 confirms whether or not automatic start of the broadcast cooperation application is permitted in the user setting of the broadcast receiving apparatus 100 (S1106).

  A user can select and set an operation setting value indicating whether or not the broadcast cooperation application can be automatically started by using a function setting menu or the like of the broadcast receiving apparatus 100 according to preference. The broadcast receiving apparatus 100, as the user selection unit 2001, provides the user with a function setting menu on a screen or the like. The user can make user settings relating to various functions by operating the remote control of the broadcast receiving apparatus 100, the linked portable information terminal 700, and the like in the function setting menu of the screen. The broadcast receiving apparatus 100 stores the user setting information in the function setting menu in a memory in the broadcast receiving apparatus 100 as an operation setting value.

  In the process of S1106, the broadcast receiving apparatus 100 confirms that the automatic activation of the broadcast cooperation application is not permitted (“No”), that is, the user does not desire the automatic activation of the broadcast cooperation application (S1107). -No), complete the process of FIG. That is, the application control unit 161 does not acquire and start the broadcast cooperation application designated by the AIT.

  On the other hand, in the process of S1106, the broadcast receiving apparatus 100 confirms that the automatic activation of the broadcast cooperation application is permitted ("OK"), that is, the user desires the automatic activation of the broadcast cooperation application. (S1107-Yes), it progresses to S1108. In the process of S1108, the broadcast reception apparatus 100 broadcasts to the predetermined service provider server 400 via the LAN communication unit 121 by the application control unit 161 based on the information described in the application acquisition destination information 905 of the AIT. Send a distribution request for linked applications.

  The service provider server 400 that has received the distribution request of the broadcast cooperation application in S1108 performs the authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103 in FIG. The predetermined broadcast cooperative application stored in the application storage area 4013 is distributed via the LAN communication unit 421 (S1109). A known method may be used for the authentication process, and the detailed description will be omitted.

  In FIG. 23, the broadcast receiving apparatus 100 first performs the processing of S1301 to S1305 which is the same as the processing of S1101 to S1105 of FIG. The broadcast receiving apparatus 100 performs the process of S1306 next, when the executability of the broadcast cooperative application designated by the AIT is confirmed by the confirmation of the application profile 904 in S1205. In S1306, the broadcast receiving apparatus 100 causes the application control unit 161 to display on the video display unit 173 a start availability confirmation screen for allowing the user to select whether to allow the start of the broadcast cooperation application.

  The user uses the portable information terminal 700 as an operation means, a remote controller, or the like to select whether to activate the broadcast cooperative application with respect to the activation availability confirmation screen displayed in S1306 (S1307). The broadcast receiving apparatus 100 receives the information of the selection as an instruction input.

  When the broadcast reception application 100 does not select the start of the broadcast cooperation application according to the result of the start possibility selection by the user in S1307, that is, when the user does not allow the start at this time (S1308-No), The present process of FIG. 23 ends. That is, the application control unit 161 does not acquire and start the broadcast cooperation application designated by the AIT.

  On the other hand, when the user of S1307 selects the start of the broadcast cooperative application by the user, that is, when the user permits the start (S1308-Yes), the broadcast receiving apparatus 100 proceeds to S1309. In the process of S1309, the broadcast reception apparatus 100 requests the predetermined service provider server 400 to distribute the broadcast cooperation application via the LAN communication unit 121 based on the information described in the application acquisition destination information 905 by the application control unit 161. Send

  The service provider server 400 that has received the distribution 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 the application storage area 4013. Is distributed via the LAN communication unit 421 (S1310).

  Next, the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400, which is received by the application engine 162 via the LAN communication unit 121 based on the control of the application control unit 161 (( S1311).

  As a modification, the processing of S1306 to S1308 may be performed after the broadcast cooperation application is acquired in the processing of S1309 to S1310.

  As in the third configuration example of FIG. 23 described above, in the sixth embodiment, it is possible to confirm the start on the screen each time for the user, and start the broadcast cooperation application when the permission is confirmed.

  In the example shown in FIG. 23, the portable information terminal 700 is made to function as an operation means of the broadcast receiving apparatus 100 in cooperation with the terminal to select the start or not. The present invention is not limited to this, and an embodiment is also possible in which the above-mentioned start / stop can be selected using a remote control or the like provided in the broadcast receiving apparatus 100 as the main body.

[Start availability confirmation screen]
FIG. 24 shows an example of the start availability confirmation screen of the broadcast receiving apparatus 100 displayed by the processing of S1306 of FIG. In the present embodiment, a message box 173f1 is displayed on the screen of the video display unit 173 of FIG. 24 as a start availability confirmation screen. The message box 173f1 includes a message indicating that a predetermined broadcast cooperative application is available, and displays “Yes” and “No” buttons for selecting whether to activate the broadcast cooperative application. An example of the message is "A broadcast cooperation application XXX can be used. Do you want to start a broadcast cooperation application XXX?" Another message example is “Start of broadcast cooperation application XXX is specified and can be started, but is it permitted to start?” Or the like.

  In the state where the message box 173f1 shown in FIG. 24 is displayed, the user uses the above operation means to select whether or not to activate (S1307). For example, the user selects the above “Yes” or “No” using the cursor key 741 ac, the determination key 741 ad, and the like on the basic screen 741 a of the cooperation control application of the portable information terminal 700 of FIG. 10A. Thus, the user can select whether or not to allow the start of the broadcast cooperative application presented in the message box 173f1 in the broadcast receiving apparatus 100, depending on the circumstances or circumstances of the user at that time.

  As a modification, in place of the above message box 173f1, an icon 173b0 representing the presence of a cooperative application as shown in FIG. 12A described above, or another mark or image is displayed on the screen to make the user select operation. It is also good. In this case, the user presses, for example, the cooperation application key 741a9 of the basic screen 741a of the cooperation control application. A predetermined broadcast cooperation application is started by this. In addition, when the cooperation application key 741a9 corresponding to the selection of the icon 173b0 is not pressed for a predetermined time or more, the display of the icon 173b0 may be controlled to be erased.

[Effects, etc.]
As described above, according to each configuration example of the broadcast receiving apparatus 100 of the sixth embodiment, there is a rule and an instruction of automatic start of broadcast managed application priority by PMT and AIT, and execution availability of the broadcast managed application by AIT is confirmed. Also in this case, the activation of the broadcast managed application can be appropriately controlled according to the user's selection. That is, according to the broadcast receiving apparatus 100 of the present embodiment, it is possible to execute a function with higher added value.

  As to which of the above first to third configuration examples and various modifications are adopted, whether it is defined as the specification of the broadcast receiving apparatus 100 or the like, or the setting of selection by the user for the broadcast receiving apparatus 100 or the like is To be possible. For example, in the configuration examples of FIG. 21 and FIG. 22, (a) “Allow start of broadcast managed application (allowed)” and (b) not allow start of broadcast managed application as operation setting values by user setting (not permitted (not It can be selected from the binary values of The present invention is not limited to this, and as a modification, in user settings, in addition to the above (a) and (b), a multi-value including (c) “inquire terminal” and (d) “confirm each time on screen” It may be selectable from The broadcast receiving apparatus 100 of this modification performs control operations according to the first to third configuration examples in accordance with the setting value of selection by the user. The process of the second configuration example is performed in the case of setting (c), and the process of the third configuration example is performed in the case of setting (d).

  In particular, in the first configuration example of FIG. 21, it is possible to control the activation of the broadcast cooperation application according to the setting of the user in advance to the broadcast receiving apparatus 100. The user can change the setting as appropriate according to his / her convenience and use the broadcast cooperation application.

  FIG. 25 shows an example in which a menu for user setting is displayed on the screen of the broadcast receiving apparatus 100. A menu for user setting 173 f 2 is displayed on the screen according to the user's operation of the remote control or the like. In the case of the first configuration example, the menu 173 f 2 includes “Allow launch of broadcast managed application” as one of setting items. The item corresponds to “whether or not to allow automatic start when automatic start of the broadcast cooperation application is designated”. The user can set whether or not the above items (a) and (b) correspond to the setting items of the menu 173f2 by turning on and off the button. The same function can be realized on the screen of the portable information terminal 700.

  Particularly, in the second configuration example of FIG. 22, it is possible to set whether or not to automatically start the broadcast managed application in units of users who own the portable information terminal 700, and further, the broadcast by the presence or absence of the portable information terminal 700 performing the cooperation operation. It is also possible to select whether to automatically start the managed application.

  An example of the setting and use will be described with reference to FIG. 20 described above. As the user setting on the portable information terminal 700, the terminal A of the user A has the setting A, and the terminal B of the user B has the different setting B. For example, the setting A is "OK" for automatic start of the broadcast cooperation application, and the setting B is "NO" for automatic start of the broadcast cooperation application. At the time of the processing of S1206 to S1209 of FIG. 22, for example, when only the terminal A of the user A is in cooperation, the terminal A is confirmed and the result is permitted to be activated. When only the terminal B of the user B is in cooperation, the terminal B is checked, resulting in that the activation is not permitted. As described above, whether to activate the broadcast cooperation application can be set in units of the portable information terminal 700 of each user, and the activation and use of the broadcast cooperation application can be performed according to the presence or absence of the portable information terminal 700 that cooperates in the situation at that time. is there.

  As a modification, a control operation can be performed in consideration of a combination of both specification or user setting in the broadcast receiving apparatus 100 and specification or user setting in the portable information terminal 700. For example, in an embodiment in which the content of the user setting in the portable information terminal 700 is prioritized over the user setting in the broadcast receiving device 100, the content of the user setting in the broadcast receiving device 100 is prioritized over the user setting in the portable information terminal 700 Any of the examples is possible.

  Further, in the second configuration example, user setting regarding whether to inquire the portable information terminal 700 whether or not to activate the broadcast cooperative application may be confirmed. In that case, the setting item corresponding to “inquire terminal” in (c) is provided in the user setting menu 173 f 2 in FIG. 25.

  In particular, in the third configuration example of FIG. 23, it is possible to control whether or not activation can be performed in units of broadcast managed applications prepared for each broadcast program. The user sees the information on the broadcast managed application and the confirmation presented on the screen, and can activate the application if it wants to activate the application at that time, and can disallow the activation if it does not want to activate the application at that time .

  In addition, in the third configuration example, user setting regarding whether or not to confirm the start of the broadcast cooperation application on the screen each time may be enabled. In that case, setting items corresponding to “Confirm each time on the screen” of (d) are provided in the user setting menu 173 f 2 of FIG. 25.

  Other examples include the following. In the other embodiments, even if the above (b) is selected and set in advance by user setting in the configuration example of FIG. 21 or 22, the broadcast managed application is forced regardless of the setting value. Prepare an option to boot In this embodiment, for example, in the data configuration of the AIT shown in FIG. 6, in addition to (1) to (4), setting values of "forced start" are prepared as setting values of parameters of the application control code 903. Do. Alternatively, the item “forced start setting” may be separately prepared as one of the AIT parameters (one of “other information” in FIG. 6). For these setting values, for example, "valid" or "invalid" can be selected.

  Furthermore, when the setting value of the application control code 903 is the above (5) “forced start” or the value of the item “forced start setting” is “valid”, the broadcast receiving apparatus 100 Control as follows. That is, the broadcast receiving apparatus 100 controls to forcibly start the broadcast managed application even when the operation setting value is set to (b). In other words, the control of this embodiment is provided with forced activation as an item above and above the item of user selection regarding automatic activation described above. In the case where the above-described forced start option is provided, for example, an application for displaying emergency information from the broadcasting station side, an application necessary for directing a specific CM, etc. have a high need for displaying and providing. The application can be suitably displayed and provided to the user.

  As another example, when the broadcast cooperation application is preinstalled in the broadcast receiving apparatus 100, processing such as acquisition of the broadcast cooperation application for the service provider server 400 described above (for example, S1108 to S1110 in FIG. 21). ) Is unnecessary.

  Information for controlling the broadcast cooperation application included in the broadcast wave is not limited to PAT, AIT, and the like, and can be applied. For example, one of the parameters (901 to 909) of the AIT of FIG. 6 may be separated and configured and provided as independent control information. The control information may be provided in a form included in the broadcast wave, or may be provided in a form different from the broadcast wave. The control information may be preset in the apparatus.

  The seventh embodiment of the present invention will be described below. 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.

  The broadcast cooperation application, which is an application used in the broadcast communication cooperation system of the present embodiment, is composed of HTML documents, and thus can be linked with other HTML documents on the network. In the broadcast managed application, operations such as activation / termination are controlled based on the AIT application control code 903 and the like included in the broadcast signal of the broadcast wave. In the non-broadcast managed application and the general application, operations such as activation / termination are not controlled by the broadcast signal. Hereinafter, the non-broadcast managed application may be referred to as the “non-broadcast application” and the general application as the “general application”.

  In the seventh embodiment, it is assumed that the transition from the broadcast managed application to the non-broadcast application and the general application is possible because the link in the HTML document constituting the broadcast cooperation application is possible. Further, in the seventh embodiment, it is assumed that the non-broadcast application and the general application can be directly activated in response to a user's instruction operation from the above-mentioned broadcast cooperation application launcher screen or the like. For example, a broadcasting station or a service provider, etc. includes information on a transition instruction to another HTML document constituting an application outside broadcasting, etc., in the HTML document of the broadcast managed application by describing a link such as a URL. . In such a case, transition from the broadcast managed application to an application outside the broadcast may occur.

  Since the non-broadcast application and the general application do not have operations such as activation / termination controlled by the broadcast signal, the user may execute the non-broadcast application and the general application while viewing a broadcast program. Then, when the user is executing an application outside the broadcast while watching a broadcast program, there is a case in which activation of a broadcast managed application linked to the broadcast program may be further requested. The request includes, for example, an instruction for activation by the application control code 903 or the like of the AIT included in the broadcast signal. That is, in this case, it is required to execute the non-broadcast application or the general application and the broadcast managed application in parallel, or to select one. It is technically possible to execute multiple applications of different types in parallel in this manner, but it may not be desirable in terms of control, and it may be inconvenient for the user.

  Therefore, the broadcast receiving apparatus 100 according to the seventh embodiment has a function of controlling activation of duplication or parallel activation of the applications or activation and termination of each application so as to be suitably coped with even in the above situation. The function controls operations including activation and termination of the second application in response to the user's selection when the second application is requested to be activated and executed while the first application is being executed. In particular, when a request for activation of the broadcast managed application is received during execution of the non-broadcast application or the like, termination of the non-broadcast application or the like or activation of the broadcast managed application is performed according to the user's instruction input or setting. Control. In the seventh embodiment, an example of the control operation of the broadcast receiving apparatus 100 in the above-described case and situation will be described.

  An example of control according to user selection by the above function is as follows. (1) The above function activates and executes the target broadcast managed application while continuing the non-broadcast application and the general application being executed when the above request is received. (2) The above function terminates the non-broadcast application and the general application being executed when the above request is received, and activates and executes the target broadcast managed application. (3) The above function keeps the non-broadcast application and the general application in progress when the above request is received, and does not activate and execute the target broadcast managed application.

  The means of user selection by the above function are as follows. (A) The above function allows the user to notify the user of a situation where a request for starting a broadcast managed application other than the currently running non-broadcast application etc. is received when the above request is received, and an application for starting or ending Alternatively, information for causing the user to select the control operation is displayed on the screen. The function accepts an operation of inputting a selection instruction by the user on the screen. The said function performs the content of control selected from said (1)-(3), for example according to a user's selection. (B) The above function accepts in advance the user setting operation by the user. The function executes, for example, the contents of control selected from the above (1) to (3) according to confirmation of the user setting information when the above request is received.

  FIG. 26 shows a system configuration including the broadcast receiving apparatus 100 of the seventh embodiment and an application example. The broadcast receiving apparatus 100 receives a broadcast wave from the broadcast station server 300 via the radio wave tower 300t, and separates a video of a broadcast program and information such as AIT. The broadcast receiving apparatus 100 appropriately acquires a broadcast managed application, which is a broadcast cooperation application, from the service provider server 400 or the like as appropriate based on information such as the AIT. The broadcast receiving apparatus 100 appropriately acquires the non-broadcast application and the general application from the service provider server 400, the other application server 500, and the like. In addition, there may be a portable information terminal 700 performing terminal cooperation with the broadcast receiving apparatus 100, and acquisition and execution of various applications are performed in a state of terminal cooperation between the broadcast receiving apparatus 100 and the portable information terminal 700 It is also good.

  The broadcast receiving apparatus 100 of the seventh embodiment has a multiple application execution control unit 2600 including a user selection unit 2601. The user selection unit 2601 is a unit that selects, based on the user's operation of the broadcast receiving apparatus 100 and the portable information terminal 700, the content of control including activation and termination of a plurality of types of applications and control such as parallel execution. . The user selection unit 2601 includes, for example, an instruction input unit that receives and processes an instruction input in the broadcast receiving apparatus 100, the portable information terminal 700, and the like according to the above (a). The user selection unit 2601 includes, for example, a user setting unit for receiving and processing user settings related to the above (b).

  The multiple application execution control unit 2600 is operated by the user and the user selection unit 2601, for example, when the AIT of the broadcast wave instructs activation of the broadcast managed application while the broadcast program is being viewed and the non-broadcast application or the general application is being executed. According to the selection of the control operation corresponding to the case, control of termination of the non-broadcast application or the like, activation of the broadcast managed application, etc. is controlled.

[Example of multiple types of apps]
FIG. 27 shows an example of document configurations of a plurality of types of applications, activation of each application, transition between applications, and the like. The broadcast wave 2010 includes video of a broadcast program, information such as AIT, and information such as BML. As described above, in the broadcast communication cooperation function, the AIT informs the broadcast reception apparatus 100 of the existence of the broadcast cooperation application and instructs control such as activation and termination thereof. For example, the broadcast managed application 2011 is activated by the information on the AIT included in the broadcast wave 2010.

  In the seventh embodiment, the broadcast cooperation application is roughly classified into (a) broadcast managed application, (b) non-broadcast application, and (c) general application. The broadcast managed application operates in the broadcast reception state based on the control signal included in the broadcast signal, and access to the broadcast resource is permitted. The non-broadcast application operates in a state where start / end and the like are not controlled by the broadcast signal, and access to the broadcast resource is permitted based on authentication and the like. The general app operates independently of the broadcast signal, and access to the broadcast resource is not permitted.

  In FIG. 27, App1 which is a broadcast managed application 2011 is composed of, for example, four documents of HTML11 to HTML14. App2 which is the non-broadcast application 2012 is composed of, for example, two documents of HTML21 to HTML22. App3 which is a general application 2013 is composed of, for example, two documents of HTML31 to HTML32. Each HTML document can be transitioned by a link indicated by a solid arrow. For example, transition from HTML 13 of App 1 to HTML 21 of App 2 and HTML 31 of App 3 is possible. The dashed arrows indicate examples of transitions between HTML documents.

  In FIG. 27, for example, according to the user operation 2020 on the above-mentioned broadcast cooperation application launcher screen, App2 which is an application outside the broadcast 2012 and App3 which is a general application 2013 can be activated. App2 is executed, for example, by reading HTML21, and App3 is executed, for example, by reading HTML31.

  An example of execution of each application alone during reproduction of a broadcast program (for example, broadcast program A) by the broadcast wave 2010 is as follows. (A1) The AIT instructs to start App1 which is the broadcast managed application 2011, and App1 is started and executed. App 1 is permitted to access broadcast program A. Then, when the termination of App1 is instructed by the same AIT, App1 is terminated.

  (A2) Based on the selection operation such as the user's instruction input, the launch of App2 which is the non-broadcast application 2012 is instructed by the broadcast cooperation application launcher screen, the link from HTML 13 of App1, etc., and App2 is launched and executed Be done. App 2 is permitted to access broadcast program A. App2 is terminated when the termination of App2 is instructed. (A3) Similarly, based on the user's selection operation, activation of App3 which is a general application 2013 is instructed by a broadcast cooperation application launcher screen, a link from HTML 13 of App1, etc., and App3 is activated and executed. . App3 is not permitted to access broadcast program A. App3 is terminated when instructed to terminate App3.

[Operation sequence at start of broadcast managed application]
FIG. 28 shows an operation sequence of the control in the case where the broadcast managed application is requested to be activated by AIT of the broadcast signal while executing the non-broadcast application while watching the broadcast program in the broadcast receiving apparatus 100 of the seventh embodiment. Show. In addition, although the case of the application outside a broadcast is demonstrated below, the case of a general application is possible similarly. In FIG. 28, it is assumed that the start of broadcast managed application priority is defined and instructed by the information on the PMT and the information such as the application control code 903 of the AIT and the start priority 907.

  In the broadcast receiving apparatus 100, activation of the non-broadcast application is instructed in response to an operation of selecting a desired non-broadcast application from the broadcast cooperation application launcher screen, for example, by the user while viewing a broadcast program by the user. Then, the broadcast receiving apparatus 100 superimposes and displays the execution screen of the non-broadcast application on, for example, the broadcast program screen (S1401). By switching the broadcast program or the like in the state of S1401, the contents of information such as PMT and AIT in the broadcast signal are updated. Even if the update is performed, the non-broadcast application is kept in the execution state because the operation such as activation / termination is not controlled by the broadcast signal.

  Next, the broadcast receiving apparatus 100 acquires the PMT data string separated by the first separation unit 132 by the main control unit 101 (S1402), and confirms the activation priority described in the PMT (S1403). In the process of S1403, for example, it is confirmed that the start priority of the broadcast managed application is high. Then, the broadcast receiving apparatus 100 acquires the AIT data string separated by the first separation unit 132 by the application control unit 161 (S1404), and confirms the application control code 903 of the acquired AIT data string (S1405). If the application control code 903 is "automatic start" in the process of S1405, the broadcast receiving apparatus 100 further confirms the application profile 904 of the AIT data string (S1406). In S1406, the broadcast receiving apparatus 100 confirms that the broadcast managed application specified in the AIT can be executed.

  When the execution is confirmed, the broadcast receiving apparatus 100 causes the application control unit 161 to display an activation selection screen (FIG. 30, etc. described later) on the video display unit 173 (S1407). The start selection screen allows the user to select the control operation related to start / end etc. of the non-broadcasting application being executed and the broadcast managed application for which automatic start is requested, in other words, to select the application to be started or ended. It is a screen including the information of In the seventh embodiment, as the selection of the control operation, it is possible to select whether to continue or end the execution of the non-broadcast application, whether to start the broadcast managed application, and the like on the boot selection screen. In other words, it is possible to select whether or not to allow parallel execution of the non-broadcast application and the broadcast managed app.

  The user uses the remote control of the portable information terminal 700 and the broadcast receiving apparatus 100 which are the operation means of the user on the activation selection screen displayed in S1407 to control the operation regarding the activation and termination of the plurality of types of applications. It chooses (S1408). The broadcast receiving apparatus 100 receives the selection result of the user as an instruction input. If the start of the broadcast managed application is not selected according to the selection result of the user in S1408 (S1409-No), the broadcast receiving apparatus 100 ends the process of FIG. That is, the application control unit 161 does not acquire and start the broadcast managed application designated by the AIT. Non-broadcast applications continue to run.

  On the other hand, if the start of the broadcast managed application is selected (S1409-Yes), the process proceeds to S1410. In S1410, the broadcast receiving apparatus 100 causes the application control unit 161 to end the operation of the non-broadcast application in execution.

  Next, the transmitting / receiving apparatus 100 transmits a distribution request of the broadcast managed application 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 of the AIT (S1412). The service provider server 400 that has received the distribution request of S1412 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 stores it in the application storage area 4013 The predetermined broadcast managed application is distributed via the LAN communication unit 421 (S1412). Then, the broadcast receiving apparatus 100 uses the application engine 162 to activate the broadcast managed application received via the LAN communication unit 121 based on the control of the application control unit 161 (S1413).

  In the above embodiment, when the start of the broadcast managed application is selected in S1409, control is performed to end the non-broadcast application in S1410. The following control is also possible without being limited to this. The broadcast receiving apparatus 100 confirms whether the end of the non-broadcast application has been selected in S1409 or in a step to be provided next thereto. The broadcast receiving apparatus 100 executes S1410 when the end of the non-broadcast application is selected according to the selection result of the user in this step, and proceeds to S1411 when the end is not selected.

  Note that, as a modification, the processing such as the activation confirmation of the above S1407 to S1410 and the termination of the non-broadcast application may be performed after acquiring the broadcast managed application in S1411 to S1412.

[Control example]
FIG. 29 shows an example of control of reproduction and execution of a broadcast program and a plurality of types of applications, corresponding to the process of FIG. 28 of the seventh embodiment. The horizontal axis shows time. In the vertical direction, reproduction of a video of a broadcast program by a broadcast signal of a broadcast wave and control instructions by AIT are shown in association with (A) first control, (B) second control, and (C) third control. (A) The first control indicates (A1) execution of App2 which is a non-broadcast application and (A2) execution of App1 which is a broadcast managed application. Similarly, (B) second control indicates (B1) execution of App2 and (B2) execution of App1. The (C) third control indicates (C1) execution of App2 and (C2) execution of App1. As described above, it is assumed that App1 which is a broadcast managed application is higher in priority than App2 which is a non-broadcast application.

  First, as an example of reproduction of a broadcast program, a broadcast program A is being reproduced in a period from time t1 to t3. At time t3 to t4, the broadcast program B is switched to, and during the period from t4 to t6, the broadcast program B is reproduced. Along with the switching to the broadcast program B, the AIT instructs the activation of App1, which is a broadcast managed application that cooperates with the broadcast program B.

  (A) In the case of the first control, App2 which is a non-broadcast application is activated by user operation or the like at time t2, for example, as in (A1), and is executed from t2. It is assumed that a start instruction of App1 is generated at t3 during execution of App2. At this time, continuation of App2 and activation of App1 are selected as user selection by the user selection unit 2601 at t3 to t4. The multiple application execution control unit 2600 of the broadcast receiving apparatus 100 starts App1 at t4 as in (A2) while continuing the execution of App2 according to the user selection, and makes the screen display state correspond to this. Control. After that, for example, in a period from t4 to t5, App1 and App2 are executed in parallel, and at t5, App2 is ended by a user operation or the like. In the period from t5 to t6, the execution of App1 is continued, and at t6, App1 is terminated in accordance with the instruction to terminate App1 by the AIT.

  (B) In the case of the second control, App2 is executed in the period from t2 to t3 as in (B1), and with the start instruction of App1 at t3, as a user selection, the end of App2 and the start of App1 are It is selected. The broadcast receiving apparatus 100 ends the execution of App2 according to the user selection, and starts App1 at t4 as shown in (B2). Thereafter, App1 is executed during a period from t4 to t6.

  (C) In the case of the third control, App2 is executed in the period from t2 to t3 as in (C1), and with the start instruction of App1 of t3, the continuation of App2 and the non-activation of App1 as user selection Is selected. The broadcast receiving apparatus 100 continues the execution of App2 according to the user's selection, and does not start App1 at t4 and does not execute it as in (C2). Thereafter, App2 is executed during a period from t4 to t5.

[Start selection screen]
FIG. 30 shows an example of the start selection screen displayed by the process of S1407 of FIG. 28 in the seventh embodiment. In this screen, a message box 173g1 is displayed. In the message box 173g1, the user confirms that the non-broadcast application is currently being executed, and that the activation of the broadcast managed application is instructed and the activation is possible, and selects whether the activation is to be performed or not Including display of a message to the effect that The message box 173g1 of this example includes “Yes” and “No” buttons for causing the user to select whether or not the activation is performed.

  While the message box 173g1 is displayed, the user selects "Yes" or "No" using, for example, the cursor key 741ac and the determination key 741ad of the basic screen 741a of the cooperative control application. That is, the user selects "Yes" when he wants to start the broadcast managed application at that time, and "No" when he wants to continue the execution of the non-broadcast application. With this screen, the user can easily start the broadcast managed application newly on the broadcast receiving apparatus 100 that is executing any desired non-broadcast application according to his / her convenience or desire at that time. It can be selected. The above control is also possible in the case of a general application.

  In addition, instead of the message box 173g1, the icon 173b0 of FIG. 12A described above and other marks are displayed to prompt a predetermined user operation, and the operation controls the activation of the broadcast managed application and the termination of the non-broadcast application by the operation. It may be in the form of For example, a mark, a message or the like indicating that there is a request for activating the broadcast managed application may be displayed on the corner of the screen. If the predetermined user operation is not performed after the display of the icon or the like, the display is erased.

  FIG. 31 shows an example of another start selection screen. In the start selection screen of FIG. 31, a message box 173g2 is displayed. The message box 173g2 includes a display of a message or the like for causing the user to select an operation of control regarding activation and termination of a plurality of types of applications including the non-broadcast application and the broadcast managed application. The message box 173g2 (1) activates the broadcast managed application while executing the non-broadcast application, (2) terminates the non-broadcast application and activates the broadcast managed application, as specific control option information ((2) 3) Do not start broadcast managed application, etc.

  With the message box 173g2 displayed, the user selects from the above options using, for example, the color key 741ae of the basic screen 741a of the cooperation control application. For example, blue corresponds to control of (1), red corresponds to (2), and yellow corresponds to (3). Also on the screen, the user can easily select termination or activation of each application according to the situation at that time.

  The above-mentioned start selection screen is not limited to the form displayed at the time of request occurrence, and a form displayed at the time of user setting is also possible. In this case, the broadcast receiving apparatus 100 displays a menu of user settings on the screen of the video display unit 173 as in FIG. 25, for example, and displays control options such as (1) to (3) in the menu. Allows the user to set preferences. The broadcast receiving apparatus 100 executes control according to the user setting information when a request occurs.

[Execution screen of multiple apps]
The broadcast receiving apparatus 100 controls the display of the screen of the video display unit 173 in the same manner as the above-described example, in the case of control of terminating the application outside the broadcast and activating and executing the broadcast managed application. That is, the broadcast receiving apparatus 100 displays, for example, the execution screen of the non-broadcast application that has been displayed on the screen of the video display unit 173 in an area different from the screen of the broadcast program or a partial overlapping area in the screen of the broadcast program. Close it and display the broadcast managed application execution screen anew.

  The broadcast reception apparatus 100 starts the broadcast managed application while continuing the execution of the non-broadcast application, that is, in the case of control to execute both applications in parallel, the display of the screen of the video display unit 173 is as follows. It may be controlled to The broadcast receiving apparatus 100 appropriately adjusts the size and display position of the execution screen of one or both applications so that the display does not entirely overlap, for example, between the execution screen of the non-broadcast application and the execution screen of the broadcast managed application. Also, both execution screens may be adjusted to overlap in some areas.

  The broadcast receiving apparatus 100 may, for example, perform processing to reduce the size of the execution screen of the non-broadcast application being executed so as not to disturb the display of the execution screen of the broadcast managed application to be newly started. Conversely, the size of the execution screen of the newly launched broadcast managed application may be reduced so as not to disturb the display of the execution screen of the non-broadcast application being executed. Also, even if the non-broadcast application is temporarily turned into an icon, only the execution screen of the broadcast managed app is displayed, and the display of the non-broadcast application execution screen is restored by the user's selection operation of the non-broadcast application icon. Good. Also, both applications may be made into icons, and the execution screen may be displayed according to the selection of the icon by the user.

  The broadcast receiving apparatus 100 displays, for example, a screen for reproducing a broadcast program in the screen of the video display unit 173, superimposes an execution screen of an application outside the broadcast on a partial area of the screen for reproducing a broadcast program, The execution screen or the like of the broadcast managed application may be superimposed and displayed on a partial area of the execution screen of the non-broadcast application. Also, the broadcast receiving apparatus 100 may divide the whole or a part of the screen of the video display unit 173 and display the broadcast program and the execution screens of both applications in parallel.

  FIG. 32 shows a screen example of the video display unit 173 corresponding to the control example of parallel execution of the plurality of applications. In the screen of FIG. 32, the execution screen of the broadcast managed application to be newly activated is displayed superimposed on a partial area 173g3 on the screen 173g for displaying a broadcast program. At the same time, the execution screen of the non-broadcasting application being executed is displayed as a reduction or an icon or the like in a partial area 173g4 in the area 173g3. When the user selects 173 g 4, the execution screen of the non-broadcast application is displayed enlarged in area 173 g 3, and conversely, the execution screen of the broadcast managed application is displayed reduced or in an icon or the like in area 173 g 4. In the area 173g4, a mark, a message or the like indicating that there is an instruction to start the broadcast managed application may be displayed.

  The screen as described above allows the user to understand and recognize the status of execution of a broadcast program and a plurality of types of applications in an easy-to-understand manner.

  FIG. 33 shows another screen example of the video display unit 173 corresponding to the control example of parallel execution of the plurality of applications. The screen shown in FIG. 33 is divided into a plurality of divided areas, including a broadcast program screen 173g, a non-broadcast application execution screen 173g5, a newly activated broadcast managed application execution screen 173g6, and a start selection and the like. An area 173g7 for displaying information is displayed in parallel. In the area 173g7, a mark indicating that there is a broadcast managed application activation instruction, a message, or the like may be displayed, or information of an application list such as the broadcast cooperative application launcher shown in FIG. 12B may be displayed. Furthermore, when there are two or more non-broadcast applications, general applications, and two or more broadcast managed apps, the execution screen of each application may be displayed in parallel.

[Effects, etc.]
As described above, according to the broadcast receiving apparatus 100 of the seventh embodiment, even when a request for activation of the broadcast managed application is generated by the AIT or the like during execution of the non-broadcast application or the general application in the broadcast receiving apparatus 100, The activation and termination of the application can be appropriately controlled according to the user's selection. That is, according to the broadcast receiving apparatus 100 of the present embodiment, it is possible to execute a function with higher added value. The user can select and use the non-broadcast application and the broadcast managed application according to the situation and convenience at the time of request occurrence.

You may do so. Similarly, after the processing up to S1406, control may be performed to automatically start the broadcast managed application while continuing the non-broadcast application without confirming the user selection. Similarly, during execution of the non-broadcast application or the general application, control may be performed so as not to automatically start the broadcast managed app without confirming the user selection. In the case of the modified example, the user has less time and effort for operation.

  As a second modification, not only confirmation of the user selection instruction input on the start confirmation screen, but also a plurality of user settings using the broadcast receiving apparatus 100 and the portable information terminal 700 as in the sixth embodiment described above. The control of the execution of the application of the type may be realized. For example, the user can select and set whether to activate the broadcast managed application or the like while the non-broadcast application or the general application is being executed, based on the user setting information from the above-mentioned function setting menu or the like. The broadcast receiving apparatus 100 stores the setting value in the storage unit 110. The broadcast reception apparatus 100 refers to and confirms the content of the user setting information of the broadcast reception apparatus 100 when, for example, the processing of S1407 to S1409 is requested when the start of the broadcast managed application is requested during execution of the non-broadcast application etc . The broadcast receiving apparatus 100 determines and determines the control such as the activation according to the content. In the case of the modification, the user can appropriately change the user setting according to his / her convenience and the like, and can use a plurality of types of broadcast cooperation applications.

As in the sixth embodiment, the activation and termination of the plurality of types of applications can be flexibly controlled according to the presence or absence of the linked portable information terminal 700 or the user setting for each linked portable information terminal 700.

  As another modified example, the broadcast receiving apparatus 100 displays information indicating that the non-broadcast application is terminated halfway and the broadcast managed application is activated, as an example of control related to the second control in (B) of FIG. After the broadcast managed application is terminated, the non-broadcast application which has been terminated halfway may be activated and executed again automatically or by a predetermined user operation. In the case of the modification, the user can easily return to the use of the non-broadcast application.

  As another modification, as a control example related to the third control of (C) in FIG. 29 above, the broadcast receiving apparatus 100 receives the broadcast managed application according to the user selection at the time when the request for activating the broadcast managed application is received. Put on hold without starting and continue running non-broadcast applications. Thereafter, the broadcast receiving apparatus 100 activates the broadcast management application that has been put on hold, for example, after the non-broadcasting application has ended. As an example of control of the screen display in this case, a message or a mark indicating that the start of the broadcast managed application is requested, a message indicating the suspension of the start, or the like is displayed at a corner or the like of the execution screen of the non-broadcast application. This prompts the user to terminate the non-broadcast application and launch the broadcast managed app. In the case of the modification, the user can shift to use of the broadcast managed application at a convenient timing.
