ABSTRACT:
A clock generation circuit for a digital video processing apparatus which has a simple structure and can be stably worked in both luminance and color signal systems. A color burst phase error signal indicative of phase difference of a color burst signal is produced on the basis of two color difference signals, a sampling clock signal is generated in accordance with the color burst phase error signal, the sampling clock is divided in order to produce a chrominance subcarrier signal, and the phase of the chrominance subcarrier signal is adjusted in accordance with the color burst phase error signal.
