Abstract
Remote-controlled electronic equipment with a transmitting function is disclosed which comprises a remote-control signal receiving section for receiving a remote-control signal containing a device address of a desired piece of electronic equipment to be controlled and command information on a desired instruction, and a communication section for transmitting a signal frame assembled on the basis of decoded data of the remote-control signal. Further disclosed is a remote-control signal transmitter for use in controlling the electronic equipment wherein a remote-control signal transmitted from the transmitter contains a device address of a desired piece of the electronic equipment to be controlled and command information on a desired instruction. The present invention still further provides a distributed remote-control system comprising at least two pieces of the electronic equipment mentioned above, a common remote-control signal transmitter mentioned above, and a signal transmission line for connecting the electronic equipments to each other, wherein the desired piece of the electronic equipment is either directly controlled when a remote-control signal from the remote-control signal transmitter is received by the desired piece of the electronic equipment, or indirectly controlled when the remote-control signal is received by another piece of the electronic equipment connected to the desired piece of the electronic equipment through the signal transmission line.
