ABSTRACT:
A video disc player comprises a gray level picture display device for displaying a gray level picture during a track jump and a phase difference detecting circuit for detecting a phase difference between a phase of a horizontal synchronizing signal involved in a reproduced video signal and a horizontal phase for a gray level display during a so-called scan reproduction mode. The horizontal synchronizing signal of the gray picture is corrected so that the above-described phase difference will fall within a tolerance range. Therefore, a satisfactory reproduced video signal without horizontal synchronization disturbance can be obtained.
