ABSTRACT:
An apparatus for processing a video signal reproduced by a reproducing head from a recording medium, on which the video signal is recorded in many parallel tracks and reproduced with the head tracing the tracks athwart, is provided with a memory which is capable of storing one field portion of the video signal. The apparatus is arranged to alternately perform writing of the video signal reproduced by the reproducing head into the memory and reading of the stored signal from the memory in a cycle of periods shorter than one field period. Each of the writing and reading periods is set at a length of time which is an integer times as long as the horizontal scanning period of the video signal.
