Abstract
Each of plural electronic devices, e.g., a television receiver, a video disc player, a video tape recorder, an audio amplifier, and a compact disc player which are placed in an audiovisual room has a light emitter and a light detector. Identification signals corresponding to the respective electronic devices are outputted from the light emitters thereof to a single remote control unit. When the remote control unit detects the identification signals, the remote control unit displays on its display unit information required to selectively operate the electronic devices corresponding to the detected identification signals. The remote control unit displays only the information relative to the electronic devices disposed in the audiovisual room. The single remote control unit can control the plural electronic devices in the audiovisual room.
