<p>A remote control system included a remote commander and a control apparatus. The remote commander (RD/R) includes a first transmitting unit (23) for transmitting a first command signal modulated based on a first carrier frequency by a first wireless transmission medium in response to an input operation. The control apparatus (10/30/50) includes a receiving unit (11,13/31/51) for receiving a wireless transmission signal transmitted from the remote commander by the first wireless transmission unit, and a second transmitting unit (12/32/56) for transmitting a second command signal modulated based upon a second carrier frequency by a second wireless transmission medium. This second command signal is to control an operation of an electronic appliance designated by the remote commander among a plurality of electronic appliances based upon an output signal derived from the receiving unit. A plurality of electronic appliances have such a receiving unit (RJ) for receiving the second command signal outputted from the second transmitting unit of the control apparatus (10/30/50), and operations of these electronic appliances are controlled in response to the output signal issued from this receiving unit. <IMAGE></p> |
