テレビジヨン受像機。 Detection means 1 detects whether the position of the video signal on the screen is within a predetermined range from the vertical synchronization signal and the horizontal synchronization signal, and outputs a detection signal when the position is within the predetermined range. and masking means that does not output the input video signal as the output video signal when the detection signal is output from the detection means 1, and outputs a waveform similar to the input video signal as the output video signal when the detection signal is not output. A television receiver with screen hiding function consisting of 2.
