摘要： A digital television receiver has a digital conversion circuit (2-23) for converting an analog video signal (1) to a digital video signal (DVS), a process circuit (32-52) for composing digital RGB signals from the digital video signal (DVS), a timing control circuit (27) for controlling the A/D converting operation of the digital conversion circuit and the composing operation of the color process circuit.

摘要： A digital TV receiver includes an A/D converter circuit (102 to 109,112 to 114) for converting an analog video signal (101) to a digital video signal (110), a signal separator circuit (126 to 129) for separating a digital chroma signal (130) and a digital Y signal (133) from the digital video signal (110), a color killer circuit (135) for gating the digital chroma signal (130) to generate a gated C signal (138) when burst components are contained in the digital chroma signal (130), and a processor circuit (139 to 144) for digitally composing RGB signals (145) from the digital Y signal (133) and the gated C signal (138). The RGB signals (145) are used as tricolor signals for a color CRT.
