Abstract

By the determination of the controlled device on a reception side of the remote control apparatus, all the devices connected to the system may be controlled by the transmitter of one unit of the remote control apparatus, and they also may be controlled by the transmitter of an already existing remote control apparatus even when a new device has been additionally connected to the system.
