具備してなることを特徴とする信号切換装置。 The audio/video signal output from the audio/video equipment is supplied to one individual terminal of the changeover switch, the television signal received by the antenna is supplied to the other individual terminal of the changeover switch, and the movable piece of the changeover switch is switched. Preferably, the signal switching device selects one of the audio/video signal and the television signal and supplies the audio/video signal to the television receiver.
It is equipped with a transmitting unit that converts the audio/video signal output from the video equipment into a wireless signal and outputs it, and a receiving unit that receives the signal output from the transmitting unit and supplies it to one individual terminal of the changeover switch. The receiving unit is connected to a distributor that divides the received signal into two systems and outputs one distribution output to one individual terminal of the changeover switch, and the other distribution output side of this distributor. A signal detecting section that detects a received signal, and a control section that switches the movable piece of the changeover switch from the other individual terminal to one individual terminal using the detection signal of the signal detecting section. Switching device.
