Note that in the first embodiment, either one of permitting the second control unit 31b to use the camera 44 (S407) or switching the interface 33 to the second control unit 31b (S408) may be performed. .

The same applies to the second embodiment, and the usage device information only needs to specify at least permission to execute the service β. By giving permission to use the camera 44 (S407, S809, S813) and switching the interface 33 as a switching unit (S408, S810, S814), in service β, scene 1, the first control unit 31a Since it has been confirmed that the camera 44 is used, the first control unit 31a uses the camera 44 when executing the service β and scene 1. Furthermore, since it has been confirmed that the second control unit 31b uses the camera 44 in the service β, scene 2, the second control unit 31b does not use the camera 44 during the execution processing of the service β, scene 2. become.

[Second modification]
The usage device information defines sub-applications to be operated by the first control unit 31a and the second control unit. For example, the version of the sub-app to be operated may be specified in the usage device information. For example, in the first embodiment, when checking the usage device information of service α (S404), the stored versions of sub-app 1 and sub-app A are Service α is started by confirming that the version is higher than each version of .

In this way, by checking the version of even the same sub-app using device information, it is possible to prevent problems caused by older versions of the sub-app.

[Third modification]
In the above-described embodiment, a configuration in which one device (explained using the camera 44 as an example) is connected to the usage device information has been described. A plurality of devices may be connected to the karaoke device 2 and managed using one device information.
