Abstract
A tangential error signal generator to be used in a PAL type video disc player in which a synchronous signal such as a pilot burst signal extracted from a color video signal read from a video disc of type is compared with a reference periodic signal so as to produce a phase error signal representative of the phase difference between the synchronous signal and the reference periodic signal. The phase error signal is amended in accordance with the jump direction and the jump distance required for a desired mode of reproduction in the video disc player such as a still, fast or slow mode of reproduction.
