摘要

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 disclosed. The remote control method is applied to an audio/visual system wherein each of a plurality of audio/visual equipments includes a microcomputer for controlling operation of the audio/visual equipment. The microcomputers of the audio/visual equipments are connected to each other by way of a bus system. One of the audio/visual equipments 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 equipments other than the audio/visual center equipment to function and transfers necessary commands to the audio/visual equipments. Also novel system feature starting method and controlling method for an audio/visual system of the type mentioned are disclosed. <IMAGE>
