ABSTRACT:
A variable-speed picture reproducing apparatus for obtaining noise-free slow-motion reproduction pictures suitable for use in a helical-scanning magnetic picture recording/reproducing system in which the tracking pilot signal is recorded along with the video signal on the video track. The apparatus include a drive for transporting the tape intermittently, a detecting arrangement for detecting that the tracking error signal derived from the pilot signal picked up during the intermittent tape transportation rises or falls across a predetermined level, and a control arrangement for performing tape stop control including a reversal braking for a capstan motor of the drive upon expiration of a delay time determined by a predetermined computation following the time point of the detection of the signal level.
