PURPOSE:To reduce the cost of a whole control system by permitting respective equipments to receive and display operation display data of the respective equipments, which is transmitted by means of a controller, with a home bus and transmitting operation indicating information inputted through the use of the display. CONSTITUTION:An operation information transmission processor 1 is connected to the respective equipment controllers A, a home bus communication control part 7 and an information channel connecting part 8 through control and information channels 11a, b and 12-14a, b. The processor 1 reads operation screen information which a controller part 4 stores in a display memory part 3 and outputs it together with voice through video converting part 5 and a video signal modulating part 6. The respective controllers A having a control part, a connecting part and a processing part which as the same as those of the controller 1 receive the signal, display it in a display part and transmit operation contents indicated by the touch pannel of the display part to the control channel. Thus, a system is easily changed and extended the whole cost is reduced. |
