Abstract of the Disclosure An oscillator produces a signal having a frequency equal to a multiple of the turntable speed of a video disc player. A divider, periodically reset by vertical timing signals produced by the player when in a "play" operating mode, divides the oscillator signal and continuously produces a vertical reference signal equal in phase and frequency to a vertical timing component of the player video output signal. Synchronism is maintained between the player and a TV receiver when the player is in a "pause" operating mode (when the video output signal is squelched) by supplying the reference signal to the receiver, thereby preventing undesirable "roll" of the image produced by the receiver when the player is returned to the "play" operating mode.
