Abstract

PURPOSE: To prevent the deterioration of vertical synchronous signal contained in the video signal by sampling the vertical synchronous signal from the reproduction video signal under normal traveling to produce a false vertical synchronous signal and by inserting or piling the false vertical signal in place of the reproduced video signal.
