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.

Abstract: A digital television receiver has a digital conversion circuit for converting an analog video signal to a digital video signal, a process circuit for composing digital RGB signals from the digital video signal, a timing control circuit for controlling the A/D converting operation of the digital conversion circuit and the composing operation of the color process circuit.

Abstract: An integrated circuit for a programmable television receiver comprises a memory for storing a plurality of programs, a digital clock and a character generating circuit for generating character signals for displaying the programs in the memory and/or time of the digital clock on the screen of a television receiver. The integrated circuit uses dynamic circuits to reduce the number of elements required, and CMOS transistors to attain a lower power dissipation.
