Abstract:
A communication control device in an audio visual device system has disconnection detection unit for detecting that an audio visual device is disconnected from the audio visual device system, device detection unit for detecting an audio visual device which has not acquired a logical address according to a device type, and control unit for performing control for causing the audio visual device without a logical address to acquire a logical address, when disconnection of a audio visual device is detected by the disconnection detection unit. With this configuration, in an audio visual device system in which an upper limit is set to the number of logical addresses according to a device type, it is possible to cause an audio visual device which cannot acquire a logical address according to the device type to acquire a logical address when it is made available.
