Description

  The present invention relates to a terminal cooperation system that realizes cooperation between a television receiver that can view a program and an information processing terminal (such as a mobile phone) that can execute an application related to the program.

Research and development for the realization of broadcast communication cooperation services such as Hybridcast (Hybrid Cast (registered trademark)) and European HbbTV (Hybrid Broadcast Broadcast TV) with the progress of digital broadcasting and broadband communications in recent years Has been done.
In such a broadcasting / communication cooperation service, contents are distributed using different transmission paths for broadcasting and communication, and a display screen of the distributed contents is displayed on a receiver such as a digital television, a personal computer, or a portable terminal. It is considered to display them simultaneously. For example, character information distributed by communication on a display screen of a broadcast program, which is a content distributed by broadcasting, using an application program (hereinafter referred to as “application”) such as a widget (or gadget) or a browser. It is assumed that communication contents such as audio and moving images are displayed in a superimposed manner.

By the way, if it is possible to freely superimpose communication contents on the display screen of a broadcast program, there is a possibility that the intention of the program producer, such as the screen configuration or program configuration, will not be transmitted to the viewer. Therefore, in recent years, an attempt has been made to keep the intention of directing a broadcast program by controlling the display of communication content by a broadcaster (program producer).
For example, Patent Document 1 discloses a content display device that distributes control information for determining a content display method in association with the content from facilities of a provider that broadcasts the content (broadcast program). It is described that the receiver determines the display method of the content display screen and the application display screen based on the control information. Thereby, a plurality of application screens can be displayed without infringing on the workability of the program.

  Even in such a case, in the terminal cooperation system 1 of the present invention, since the information processing terminal 4 specifies the viewing scene in the receiver 3 and requests the application, It is configured to be able to provide services linked with program content. That is, in FIG. 8 (1), the voice service corresponding to the comment “Good morning” is output, and in FIG. 8 (2), the voice service corresponding to the comment “Goodbye” is output. As described above, according to the terminal cooperation system 1 of the present invention, it is possible to provide a service linked to the program content being viewed for each user.

  Moreover, the terminal cooperation system 1 of the present invention executes an application suitable for the device state (application execution environment) of the information processing terminal 4 owned by the user. Specifically, referring to FIG. 9, before accessing the service server 7, the information processing terminal 4 uses the location information of the service server 7 that manages the version of the application corresponding to the device state of the own terminal as the service location. The management server 6 is inquired. In FIG. 9, the information processing terminal 4 of the user A2 inquires the location information of the service server 7 that manages the version of the application corresponding to the OS “ΔΔ”, and the information processing terminal 4 of the user A3 The location information of the service server 7 that manages the version of the application corresponding to “×” is inquired. As a result, the service location management server 6 returns the location information of the service server 7A to the information processing terminal 4 of the user A2, and the location information of the service server 7B to the information processing terminal 4 of the user A3. . Thereby, the information processing terminal 4 of the user A2 and the information processing terminal 4 of the user A3 can acquire the application corresponding to the device state of the own terminal, and the scheduled service is appropriately provided. Thus, in the terminal cooperation system 1 of the present invention, the terminal cooperation service can be provided without affecting the difference in the device state (application execution environment) for each information processing terminal 4.
