PURPOSE:To easily cope even with the construction of a large-scale system and the expansion of audio visual equipments and to quickly and accurately control the audio visual equipment in the controller of the audio visual equipment for integratedly controlling the various kinds of the audio visual equipment installed in an audio visual room and a conference room. CONSTITUTION:On an integrated control circuit 10 side, only the control signals of minute information quantity corresponding to the operation of an integrated operation part 30 are processed and outputted to a system bus SB. In such a manner, high-speed communication is enabled through the system bus SB. An interface circuit on the side for receiving the control signals of the minute information quantity prepares the operational signals of the complicated and large information quantity for operating the equipment connected to the interface for realizing an operation corresponding to the control signals, outputs them to the audio visual equipment and operates the equipment. |
