とを特徴とするテレビジヨン受像機。[Claims for Utility Model Registration] A still playback mode detection circuit that detects whether an incoming video signal is a video signal from a still playback mode of a video disc player, and processes the video signal in accordance with the detected signal. A television receiver configured to switch modes includes a noise detection circuit that detects when a predetermined amount or more of noise is mixed into the incoming video signal, and a still playback mode when the noise detection circuit detects it. A television receiver comprising still reproduction mode detection signal blocking means for forcibly disabling the detection signal.
