ABSTRACT:
A color video signal recording and reproducing apparatus comprises a first circuit for delaying by a time period T a reproduced time-compressed line-sequential color difference signal in which time-compressed first and second color difference signals are alternately transmitted in time sequence for every time period T, a second circuit for delaying a reproduced luminance signal by a time period 2nT+.alpha., where n=1 or 2 and 0.ltoreq..alpha..ltoreq.T, and a time base expanding circuit supplied with the reproduced time-compressed line-sequential color difference signal and an output signal of the first circuit for writing these signals into a memory responsive to a first clock pulse produced based on a synchronizing signal within the reproduced time-compressed line-sequential color difference signal and for reading out the stored signals responsive to a second clock pulse produced based on a synchronizing signal within an output delayed reproduced luminance signal of the second circuit, so as to simultaneously output in parallel first and second color difference signals having the time base thereof expanded and returned to the original time base and matched with the time base of the reproduced luminance signal.
