ABSTRACT:
A digital TV receiver includes an A/D converter circuit for converting an analog video signal to a digital video signal, a signal separator circuit for separating a digital chroma signal and a digital Y signal from the digital video signal, a color killer circuit for gating the digital chroma signal to generate a gated C signal when burst components are contained in the digital chroma signal, and a processor circuit for digitally composing RGB signals from the digital Y signal and the gated C signal. The RGB signals are used as tricolor signals for a color CRT.
