Claims

[Claim for Utility Model Registration] A demodulation circuit that outputs video and audio signals of a predetermined channel from the output of an antenna for receiving television broadcasting, and a demodulation circuit that samples the video signal from the demodulation circuit at a predetermined frequency. an analog-to-digital conversion circuit that performs quantization; ゛ a memory circuit that sequentially stores the quantized signals from this analog-to-digital conversion circuit for each frame of the screen; − the quantized signals stored in this memory circuit; A memory readout circuit that outputs a signal, a digital-to-analog conversion circuit that converts the output from the memory readout circuit into a video signal, and a control signal of a predetermined size depending on the level of the video signal output from the demodulation circuit. a switch circuit that determines whether to pass the video signal from the demodulation circuit or the video signal from the digital-to-analog conversion circuit based on a control signal from the level determination circuit; A television receiver mounted on a car tower, comprising: a display that displays the video signal from the switch circuit; and a speaker system that converts the audio signal from the demodulation circuit into audio.
