ＳＥ信号の発生を阻止するゲート回路とを、 それぞれ設けて成るミユート回路。[Claims for Utility Model Registration] Playback of a video record made by FM modulating a MUSE signal obtained by band-compressing a high-quality video signal using the TCI multiplex subsampling method and frequency multiplexing recording together with a constant frequency pilot signal. A high-definition video disc player that uses a high-definition video disc player includes: a gate control circuit that generates a gate control signal when a reproduced pilot signal frequency is out of a predetermined range; and an MU that is FM demodulated based on the gate signal.
A mute circuit is provided with a gate circuit and a gate circuit that prevents the generation of SE signals.
