[1.1 System configuration]
FIG. 1 is a diagram illustrating an entire broadcasting / communication cooperation system 1 according to the present embodiment. In the broadcasting / communication cooperation system 1, the digital broadcasting receiving apparatus receives broadcasting content from the broadcasting station BS. Here, the digital broadcast receiving apparatus includes a digital broadcast receiving apparatus A as its own terminal, digital broadcast receiving apparatuses B1 to Bn as other terminals, and one or a plurality of digital broadcast receiving apparatuses. Furthermore, the digital broadcast receiving apparatus A is connected to the application server SV via the communication network NW. In the present embodiment, the application server SV is single, but it goes without saying that there may be a plurality of application servers SV.

  Briefly explaining each device and the like, the broadcasting station BS is equipped with a broadcasting facility for digital broadcasting, and modulates and transmits a broadcast signal obtained by multiplexing broadcast content data into a broadcast wave.

  The digital broadcast receiver receives a broadcast wave from the broadcast station BS, demodulates the broadcast signal, and separates and decodes video, audio, and application control information multiplexed from the broadcast signal and reproduces them.

  In some cases, application control information is acquired from the application server SV by communication based on an instruction of a data broadcast script (BML).

  The digital broadcast receiving apparatus is connected to the application server SV via the communication network NW. An application is downloaded from the application server SV based on the application control information and executed.

  Here, in the present embodiment, the application is data conforming to the HTML5 recommendation defined by W3C (World Wide Web Consortium), and communication with the application server conforms to the protocol HTTP / HTTPS.

  In addition, the receiving device (digital broadcast receiving device) executes the application by the HTML5 browser function that implements the specifications defined in IPTVFJ STD-0011.

  Note that in the present embodiment, execution is possible even in accordance with other data formats, communication protocols, and application execution programs.

  The application control information is used to provide or make known various information necessary for starting an application such as an application acquisition destination, and control information such as starting and ending the application. The application control information includes application profile information. The application profile information is information on a receiving device function necessary for executing the application, and the receiving device determines whether or not the application can be executed.

  In addition, the digital broadcast receiving device has a communication function with one or a plurality of other digital broadcast receiving devices, and can exchange application execution permission determination request / response and application execution request / response messages with each other. It is.

  When receiving the application execution feasibility determination request message, the digital broadcast receiving apparatus determines whether the application can be executed based on the application profile information included in the message, and returns a response with the determination result.

  Further, when the digital broadcast receiving apparatus receives the application execution request message, it receives broadcast content based on the channel selection information included in the message. When receiving the application execution request, the digital broadcast receiving apparatus may display a dialog for confirming whether or not the application is executable.

  The application server SV receives an application download request for an application from the digital broadcast receiving apparatus, and transmits application data to the digital broadcast receiving apparatus.

  In response to a request for downloading application control information from the digital broadcast receiving apparatus, the application control information is transmitted to the digital broadcast receiving apparatus.

[1.2 Functional configuration]
Next, the functional configuration of the digital broadcast receiving apparatus will be described. Note that the digital broadcast receiving apparatus may be a single apparatus or may be incorporated into an information terminal such as a mobile phone, a smartphone, or a tablet, or another apparatus such as a car navigation system or a computer. Note that this configuration is common to the digital broadcast receiving device A that is its own terminal and the digital broadcast receiving devices B1 to Bn that are other terminals.

  The tuner unit 110 is a functional unit that receives a broadcast signal, performs demodulation processing and decoding processing, and outputs a stream signal to the demultiplexer unit 120.

  The demultiplexer unit 120 is a functional unit that separates video, audio, and data broadcast data from the input stream signal and outputs the separated data to the broadcast content reproduction unit 130. Further, the application control information is separated and output to the application control unit 200.

  The broadcast content reproduction unit 130 decodes video data and audio data included in the broadcast content, and outputs them to the output unit 500 as video signals and audio signals.

  Also, data broadcast data is decoded, and based on the obtained script (BML), detection of user operations by output of video and audio signals, remote control input, touch panel input, etc., processing corresponding thereto, and download of application control information I do.

  The storage unit 300 is a functional unit that stores various programs and various data necessary for the operation of the digital broadcast receiving apparatus. The storage unit 300 is configured by, for example, a semiconductor memory.

  In the storage unit 300 in the present embodiment, own device profile information 310 and an application executable terminal list 330 are stored.

  Here, the own device profile information 310 is information relating to a function profile indicating an executable function of the own device (digital broadcast receiving apparatus A).

  The application execution terminal list 330 is a table that manages whether each digital broadcast receiving apparatus can execute an application. It is updated by executing processing according to this embodiment.

  The application control unit 200 determines whether or not an application (application) can be executed by taking out the application profile information from the input application control information and comparing it with the own device profile information 310.

  If the application can be executed, the application is downloaded from the application server SV via the communication unit 600 and an execution request is issued to the application execution unit 400.

  On the other hand, if the application cannot be executed, the application profile information is transmitted to the application execution terminal. Furthermore, when there is a response indicating that the application can be executed from another application execution terminal, an application execution request is transmitted.

  The application execution unit 400 is a functional unit for receiving an application execution request and executing the application.

  The output unit 500 is a functional unit for outputting various input video data, audio data, and information. For example, it is a functional unit that outputs to a display device such as an LCD or another display device connected by HDMI (registered trademark). Also, the input data outputs audio data (or audio data included in the video data) to a speaker or the like.

  The communication unit 600 is a functional unit for connecting to the communication network NW. For example, a wireless LAN such as WiFi or a WAN line such as a 3G line is used. In the case of the present embodiment, any communication unit 600 that can establish a communication path capable of communicating with the application SV may be used.

  Although not shown in FIG. 2, a control unit is incorporated to control each functional unit and the digital broadcast receiving apparatus. The control unit is a functional unit for controlling the entire digital broadcast receiving apparatus. The control unit implements various functions by reading and executing various programs stored in the storage unit 300, and is configured by, for example, a CPU (Central Process Unit).

[1.3 Process flow]
Next, the flow of processing of this embodiment will be described. Each of the processes is a process realized when the control unit reads and executes a program stored in the storage unit 300.

[1.3.1 Broadcast reception processing]
First, processing when the digital broadcast receiving apparatus A receives broadcast content will be described with reference to FIG. That is, it is a process of receiving broadcast content, inquiring the digital broadcast receiving devices B1 to Bn whether or not execution is possible, and requesting execution.

  First, the digital broadcast receiving apparatus A starts receiving broadcast content (step S102). The tuner unit 110 outputs a stream signal to the demultiplexer unit 120. Then, the demultiplexer unit 120 separates the application control information and outputs it to the application control unit 200.

  The application control unit 200 extracts application profile information from the application control information (step S104). Then, by comparing with the own device profile information 310, it is determined whether or not the application can be executed (step S106).

  If it is determined that the application cannot be executed on the own device (step S106; No), the executable terminal process described below is executed from among the other digital broadcast receiving devices B1 to Bn. Search is performed (step S108).

  Here, when there is another device that can be executed (step S110; Yes), an application execution request message is transmitted to all the other devices that can be executed (step S112). The application execution request message includes channel selection information and access information. In addition, the channel selection information includes channel information of broadcast content linked with the application and a service ID. The access information includes an access path and an access type.

  When the application control information is received from the broadcast, the access type is “broadcast” and the application identifier is sent as the access path. On the other hand, when the application control information is received by communication, the access type is “communication” and the URL is sent as the access path.

  If it is determined in step S106 that the app can be executed by the own device, the app is executed by the own device (step S114).

[1.3.2 Executable terminal search process]
Next, processing executed to search for an executable other device will be described with reference to FIG. The executable terminal search process in FIG. 3 is a process flow executed in the digital broadcast receiving apparatus A.

  First, the application control part 200 calculates | requires the terminal number n which can communicate (step S202). Here, “communicable” means that the communication session is initialized in accordance with a predetermined communication protocol, and the application execution determination request / response message can be transmitted and received. For example, an ID of a digital broadcast receiving device that has completed initialization of a communication session with the digital broadcast receiving device A according to a predetermined protocol is registered in the communicable terminal list, and the digital broadcast registered in the communicable terminal list is registered. Detect the number of receiving devices.

  The initial value of the variable i is set to “1” (step S204). Thereafter, the application profile information is transmitted to the digital broadcast receiving apparatus Bi (step S206). Here, the digital broadcast receiving apparatus B determines which digital broadcast receiving apparatus to transmit according to the value of i. For example, since “i = 1” initially, the application profile information is transmitted to the digital broadcast receiving device B1 (step S206).

  Here, the digital broadcast receiving device B1 is specifically determined with reference to the communicable terminal list. For example, the digital broadcast receiving device B1 is selected as the digital broadcast receiving device stored first in the communicable terminal list (i = 1).

  Thereafter, when a determination result is received from the digital broadcast receiving device Bi (for example, B1) (step S208), it is determined whether or not the application is executable (step S210).

  At this time, if it is determined that the application can be executed (step S210; Yes), the digital broadcast receiving device Bi (if i = 1, the digital broadcast receiving device B1) is added to the application executable terminal list 330 (step 1). S212).

  If the variable i is less than n (step S214; No), 1 is added to i (step S216), and the process is repeated from step S206.

  On the other hand, when the variable i becomes n or more (step S214; Yes), this process is terminated.

[1.3.3 Application execution availability determination process]
Next, the flow of processing when an application execution determination request is received will be described with reference to FIG. The process is a process flow common to other digital broadcast receiving apparatuses (digital broadcast receiving apparatuses B1 to Bn). That is, it is a process of receiving an application execution availability determination request message, determining whether the application can be executed, and returning a response message.

  First, the digital broadcast receiving device B (B1 to Bn) receives an application execution availability determination request message (step S302). The message includes application profile information.

  The application control unit 200 extracts application profile information from the received message, compares it with the own device profile information 310 (profile information of the digital broadcast receiving device B), and determines whether or not the application can be executed (step S304).

  Note that it may be determined that the application cannot be executed when a predetermined setting is made by a user's operation of the receiving device or execution of a program on the receiving device. For example, it may be determined to be disabled if the receiving device has already received a broadcast and video / audio presentation has started, or may be determined to be disabled if the broadcast is being recorded.

  If the application can be executed, a message indicating execution is returned to the requesting terminal device (step S306 → step S308). On the other hand, if the application cannot be executed, a message indicating that the application cannot be executed is transmitted to the requesting terminal device (step S306; No → step S310).

  Note that this processing may be performed in the background so that the user does not have to interrupt the execution of the application used when receiving the request message.

(Data structure of application profile information and function profile information)
Here, the profile will be described. The profile stores information on functions used by the application and information on functions that can be used by the digital broadcast receiving apparatus. For example, the data structure of application profile information will be described with reference to FIG. The application profile information can be expressed as bit string data. Each bit represents an individual function, and a function necessary for application execution is represented by “1”, otherwise “0”.

  For example, bit0 represents a camera-captured still image acquisition function, bit1 represents a camera-captured video acquisition function, bit2 represents a position information acquisition function, and a function for each bit. The function profile information of the digital broadcast receiving apparatus also has the same data structure, and the function corresponding to each bit is the same.

The comparison method of the application profile information and the function profile information of the receiving apparatus, and the application executable condition of the receiver are as follows.
Pa AND Pr = Pa
It can be expressed as. Here, the operator AND means that a logical product is obtained for each bit of the bit string of the operand.

[1.3.4 Application execution processing]
Next, the flow of processing when an application execution request is received will be described with reference to FIG. This application execution process is a process for executing an application upon receiving an application execution request, and is a process common to the digital broadcast receiving apparatuses B1 to Bn.

  First, the digital broadcast receiving apparatus receives an application execution request message (step S402). Next, the digital broadcast receiving apparatus presents a user dialog and inquires of the user whether or not to execute the application (step S404).

  Here, when the user selects application execution (step S406; Yes), channel selection information is extracted from the application execution request message, and reception of broadcast content is started based on the channel selection information (step S408).

  Then, application control information is acquired (step S410). Specifically, when the access type is “broadcast”, the application control information received as a section or data carousel included in the broadcast content is acquired that matches the application identification indicated by the access path. . If the access type is “communication”, the URL indicated by the access path is accessed to obtain application control information.

  Subsequently, the application is downloaded from the application server SV based on the application control information and executed (S412).

[1.4 Action / effect]
Thus, according to the present embodiment, it is possible to take over execution of an application from a digital broadcast receiving device that does not satisfy the application profile to a digital broadcast receiving device that satisfies the application profile. Therefore, it is possible to prevent the viewer from missing the use opportunity of the application.

  In addition, since the application profile is received upon reception of the broadcast content and the application execution can be taken over, it is possible to find a digital broadcast receiving apparatus that can execute the application before the application execution starts.

  Thereby, it is possible to prevent the execution of the application from being disabled during the execution of the application.

[2. Second Embodiment]
Next, the second embodiment will be described. 2nd Embodiment demonstrates the Example which makes a television cooperation terminal perform application preferentially as another digital broadcast receiver.

  Since the configuration of the digital broadcast receiving apparatus is the same as that of the first embodiment, only the processing flow will be described with reference to FIG.

  Here, the TV cooperation terminal is a C.I. of “IPTVFJ STD-0010”. 5 refers to a terminal that starts the companion app described in 5, and is connected to the receiving device for communication. In addition, the companion application downloads the program-linked application designated by the broadcast content from the application server SV and executes it.

  In addition, the digital broadcast receiving apparatus and the cooperation terminal mutually discover devices on the network using a protocol such as UPnP.

  After the device discovery, the digital broadcast receiving apparatus and the cooperation terminal establish a cooperation session by exchanging messages in accordance with a predetermined communication protocol, and enter a state of terminal cooperation. In addition, the cooperation session starts when the user operates the cooperation terminal or the digital broadcast receiving apparatus.

  During terminal cooperation, the digital broadcast receiving device receives predetermined data included in the broadcast content (for example, general-purpose messages transmitted by a data carousel) and user's device operation (for example, data broadcasting operation using a remote control). As an opportunity, a message is sent to the cooperation terminal. Moreover, a cooperation terminal transmits a message to a digital broadcast receiving apparatus with an operation by a user as a trigger.

  The digital receiving device A adds the identifier of the cooperation terminal to the application executable terminal list 330 at the start of the communication session with the cooperation terminal. Further, the digital receiving device A deletes the identifier of the cooperation terminal from the application executable terminal list 330 at the end of the communication session with the cooperation terminal.

  Here, FIG. 8 replaces part of the processing of the digital broadcast receiving apparatus of FIG. The processes common to those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted.

  That is, when the application cannot be executed by the own device, the cooperative terminal is searched (step S106; No → step S502). For example, the application executable terminal list 330 is confirmed, and it is confirmed whether or not a cooperation terminal is included.

  If there is a cooperation terminal, an application execution availability determination request message is sent to the cooperation terminal to obtain a response (step S504).

  Here, if there is a cooperation terminal capable of executing the application, an application execution request message is transmitted to the cooperation terminal capable of executing the application (step S506). If there is no linked terminal that can execute the application, a terminal that can be executed from another digital broadcast receiving apparatus is searched (step S504; No → step S108).

  In the case of No in step S504, that is, if the application cannot be executed on the cooperation terminal, this process may be terminated.

  As a result, the transmission range of the application execution request message is limited to the digital broadcast receiving apparatus that is the cooperation terminal, so that the message communication is limited to a terminal that is likely to be used by the user, and the processing time can be shortened.

  When the cooperation terminal receives the application execution request message, the application execution process of FIG. 7 is executed in the cooperation terminal. In FIG. 7, when the digital broadcast receiving apparatuses B1 to Bn receive the application execution request, the program-linked application is executed.

  In the case of the cooperation terminal, when the application is executed in step S412, the companion application and the program linkage application may be executed in parallel without ending.

  Further, the message transmission destination of the program-linked application may be switched from the digital broadcast receiving device A to the own device (looped back).

  That is, the terminal cooperation between the digital broadcast receiving apparatus A and any one of the digital broadcast receiving apparatuses B1 to Bn is made to be the cooperation between applications in the respective receiving apparatuses of the digital broadcast receiving apparatuses B1 to Bn. May be.

  As a result, even when the application cannot be executed by the digital broadcast receiving device A, the execution of the application is taken over by any of the digital broadcast receiving devices B1 to Bn, and the cooperation application is executed by any of the digital broadcast receiving devices B1 to Bn. Can also be executed.

  When Bx among the digital broadcast receiving devices B1 to Bn executes an application in step S406 in FIG. 7, Bx notifies the digital broadcast receiving device A that the application is executed, and the digital broadcast receiving device A The digital broadcast receiving apparatus other than Bx in the application executable terminal list 330 is notified of this, and the received digital broadcast receiving apparatus switches the terminal cooperation destination from the digital broadcast receiving apparatus A to the digital broadcast receiving apparatus Bx. You may do it.

  Thereby, even when the application cannot be executed by the digital broadcast receiving apparatus A, the execution of the application is taken over by the digital broadcast receiving apparatus Bx, and the digital broadcast receiving apparatuses B1 to Bn can also execute the cooperative application in cooperation with Bx.

  As described above, according to the present embodiment, the cooperation terminal that cooperates with the digital broadcast receiving apparatus executes an application related to the digital broadcast program that the user is viewing. There is a high possibility that the user is operating at hand.

  Therefore, preferentially requesting the linked terminal to take over application execution notifies the terminal that is most likely to be used by the user of the application execution request. The possibility of completing in a short time increases.

[3. Third Embodiment]
Next, a third embodiment will be described. In this embodiment, when the receiving apparatus has already received a digital broadcast, the application cannot be taken over and executed.

  Specifically, when the digital broadcast receiving devices B1 to Bn are currently receiving broadcast content and outputting video or audio in step S304 of FIG. It is determined that it is impossible.

  Even if the application execution request is received in step S402 in FIG. 7, the subsequent processing in FIG. 7 may not be performed.

  In addition, when a predetermined setting is performed by the user, for example, when “ignore application execution request from the outside” is set from the setting function provided with the GUI, it may be impossible to take over and execute the application. .

  As described above, according to the present embodiment, it is possible to prevent the user's viewing of the program from being hindered by the notification (dialog display or the like) to the user accompanying reception of the application execution request.
