Abstract
A digital processing circuit for a video signal digital by processing a composite video signal. More specifically, a composite video signal is separated into a luminance signal and a color signal by means of a Y/C separator (10). The color signal separated is converted into a signal having low frequency by means of a low frequency converter (11) that the signal having low frequency is converted into a digital signal by means of an A/D converter (13). The luminance signal separated is converted into a digital signal by means of an A/D converter (12). Digital signals are transmitted through a transmission line (5). The transmitted luiminance signal is converted into an analog signal by means of a D/A converter (14) so that the analog signal is supplied to a Y/C mixer (17). The transmitted color signal is converted into an analog signal by means of a D/A converter (15) and the analog signal thus obtained is demodulated to a signal having the initial frequency by means of a demodulator (16) so that the signal having the initial frequency is supplied to the Y/C mixer (17). The Y/C mixer (17) mixes the luminance signal converted into the analog signal and the color signal converted to the signal having the initial frequency so that an output signal is provided therefrom.
