Abstract
A digital time base corrector which can perfectly eliminate residual errors. A sync clock signal whose phase is synchronized with a time base fluctuation included in a reproduction video signal is formed in accordance with at least one of the horizontal sync signal and the color burst signal which are separated from a reproduction video signal. The sync clock signal is phase-modulated in accordance with a burst error signal indicative of the time base fluctuation of the color burst signal in a period of time other than the generating period of time of at least the color burst signal in the reproduction video signal, thereby obtaining a write clock signal of the image memory.
