Abstract
Furnishing a signal having an amplitude corresponding to the difference between the recording and playback speed of a tape recorded color television signal, the phase of the color burst of two successive lines is compared. When the speed difference includes a known difference such as, for example, for slow motion reproduction, a compensating delay is added to the single line delay of the known apparatus and simultaneously a DC voltage corresponding to the so-added delay is added to the error signal derived from the phase comparator. The additional delay and the additional voltage for the error signal are automatically inserted into the circuit by ganging a switch or potentiometer for the additional delay and for the additional voltage to the speed control for the tape drive.
