Abstract

A remote control method for an audio/visual system which can perform protection during execution of a system feature and is convenient in use is applied to an audio/visual system wherein each of a plurality of units of audio/visual equipment includes a microcomputer for controlling operation of the audio/visual equipment. The microcomputers of the audio/visual equipment are connected to each other by way of a bus system. One unit of the audio/visual equipment is set as an audio/visual center equipment. The audio/visual center equipment controls the entire system in a concentrated manner. The audio/visual center equipment receives remote control signals in a concentrated manner without causing remote controller receiver sections of the audio/visual equipment other than the audio/visual center equipment to function and transfers necessary commands to the other audio/visual equipment.
