Abstract
An apparatus for reproducing a video signal by detecting a video signal recorded on a rotary recording medium. The apparatus includes a variable delay for inputting and delaying a detected video signal, a phase comparator for comparing each phase of a timing signal, such as a horizontal sync signal, or the like, obtained from input and output sides of said variable delay, and a voltage-controlled oscillator for controlling a delay period of a variable delay receiving the output of a comparator.
