The output terminal 1a of the first enclosure 1 is connected to the input terminal 2a of the second enclosure 2 via a transmission line 8. The composite signal supplied to the input terminal 2a is supplied to the monitor television receiver 10, and the composite signal is also transmitted to the synchronous separation circuit 16.
Further, this composite signal is supplied to the adjustment signal extraction circuit 17. The synchronization signal obtained at the output side of the synchronization separation circuit 16 is supplied to the adjustment signal extraction circuit 17 as a timing signal. In this adjustment signal extraction circuit 17, a contrast adjustment signal Sa, a color adjustment signal Sb and a volume adjustment signal are
A control signal corresponding to each of Sc is generated, this control signal is supplied to the control circuit 12, and this control circuit 12
