ABSTRACT:
A video signal reproducing apparatus plays back at a high speed a recorded signal recorded on a recording medium, eliminating noise bars in the reproduced image by replacing a noise portion, that is, a signal portion reproduced by a magnetic head having a different azimuth from the azimuth of a track on the recording medium, with a corresponding signal portion of a previously reproduced track having the same azimuth as the magnetic head. The recorded signal is a shuffled video signal having mutually adjacent lines of one field recorded on different tracks of the recording medium in a predetermined sequence. Then the apparatus deshuffles the reproduced signal devoid of noise bars to obtain a deshuffled video signal.
