Abstract
A time-base error correction circuit for use in a video disk player, video tape player, or the like, with which all residual time-base error is eliminated. A detector circuit detects the amount of residual time-base error between the reproduced video signal and a write clock signal. A variable delay circuit disposed prior to a memory in which the video signal is stored adjusts the delay of the reproduced video signal accordingly.
