ABSTRACT:
In a system for correcting tracking errors in a video disc player, digital information, corresponding to field numbers is encoded on the video signal during one horizontal line of the res ective vertical blanking interval. Tracking errors, such as a locked track condition or a skipped track condition are detected by noting improper sequence of two or more decoded field numbers. A kicker apparatus is provided to move the signal pickup device in a direction so as to reduce the tracking error.
