ABSTRACT:
A digital TV receiver includes an apparatus for generating a skew corrected clock. The apparatus consists of a fixed frequency, free running oscillator for producing a signal having a frequency which is a fixed integer multiple K of the desired nominal frequency of the skew-corrected clock signal, and a divide-by-K circuit which is reset once every horizontal line. In accordance with another aspect of this invention, the state of the divide-by-K circuit is captured and saved for use in a chroma demodulation apparatus just before it is reset.
