Abstract
A signal transmitter and receiver (or a combination thereof) incorporated for example in audio and video apparatus such as a TV and a video-deck, comprises a synchronizing signal separator separating a synchronizing signal from video-signal, a monostable circuit of which period recovering its stable state, or unstable period, after an input of triggering signal, is longer than the period of synchronizing signal separated by the synchronizing signal separator, and a dc-power supply on-off controller controlling the on-off of dc-power supply according to the output of the monostable circuit. The dc-power supply on-off controller limits the supply of dc-power to a minimal number of circuits except during signal processing.
