Abstract:
A remote control system for transmitting a remote control signal transmitted from a remote control signal generator among devices which are connected to one another through a serial bus for transmitting digital data bi-directionally, wherein each device includes:remote control signal reception means for receiving the remote control signal; conversion means for converting the remote control signal to remote control data in the data format of said serial bus; transmission means for transmitting the remote control data converted by said conversion means through said serial bus to another prescribed device of said devices which are connected to said serial bus; remote control data reception means for receiving the remote control data from said other device; response means for transmitting a response to the remote control data received by said remote control data reception means through said serial bus to said other device; response reception means for receiving the response which is transmitted through said serial bus by said response means of said other device; and remote control data transmitting means for generating remote control data corresponding to the response received by said response reception means and transmitting the remote control data to said remote control signal generator; wherein at least one of said devices has a mode in which the remote control signal from said remote control signal generator is received and a mode in which the remote control signal from said remote control signal generator is not received, and said at least one device further includes: first restricting means for restricting the number of said devices for receiving the remote control signal; and second restricting means for restricting the number of said devices for transmitting the remote control data corresponding to the response to the remote control signal.
