Abstract
A remote control system which can control a plurality of remote control units (RCUs). The remote control system includes a first memory for storing an RCU identification code for each of the remote control units, a second memory for storing a maker identification code for the remote control apparatus corresponding to the RCU identification code, a model code, and a remote control code. The system further includes a device for reading an active remote control code from the second memory on the basis of the RCU identification code read from the first memory according to the apparatus control request from an active remote control unit. Electromagnetic waves or infrared rays act as a second modulated wave which is modulated on the basis of the active remote control code in order to control the function of the remote control apparatus corresponding to the active remote control code. The plurality of remote control units are managed by a single remote control reception and processing device.
