However, the viewing scene at user A's home is the program start scene (the commentator says “Good morning”) (FIG. 8 (1)), and the viewing scene at user B's home is the program end scene (moderator). The comment is “Goodbye” (FIG. 8 (2)).

  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.
