Apparatus for correcting time base error of video signal

摘要

An apparatus for correcting a time base error of a video signal. Signal portions of the video signal are sequentially written in memories with a write clock signal synchronizing with the video signal at specific write timings and sequentially read from the memories with a read clock signal of a constant frequency at specific read timings. At least one of the read timings are changed so that a correlation among the signal portions sequentially read from the memories remains unchanged when a difference between the write and read timings are smaller than a reference value.
