First Claim
1. A control apparatus of an audio-visual display apparatus, wherein a plurality of remote control units are associated with the audio-visual display apparatus, one remote control unit in the plurality of remote control units has a control right for controlling the audio-visual display apparatus, and other remote control units do not have the control right, the control apparatus comprising:
- a receiving part for receiving an operation command and a remote control unit ID sent from a remote control unit;
a determining part for determining whether a signal is received from a remote control unit with the control right until a first predetermined time elapses, the first predetermined time is started from a time when detecting that an operation command is received from a remote control unit without the control right, the control right being transferred to the remote control unit without the control right if no signal is received from the remote control unit with the control right until the first predetermined time elapses;
a control right depriving and providing part for depriving the remote control unit with the control right of the control right and providing the control right to another remote control unit if a signal is not received from the remote control unit with the control right within the first predetermined time.
