ABSTRACT:
An apparatus for reproducing a color video signal recorded in a recording medium by a time compressed integration signal format in a luminance signal, one of two types of chrominance signals being selected by a predetermined rule in every horizontal scanning period, and a chrominance index signal representing the type of the selected one of chrominance signals are multiplexed along a time base, includes at least two cascade-connected 1H delay circuits for delaying at least the chrominance signal in a signal reproduced from the recording medium, an extraction circuit for extracting the chrominance index signal from the reproduced signal, at least two cascade-connected latches, connected to an output of the extraction circuit, for holding extracted the chrominance index signals respectively corresponding to output signals from the 1H delay circuits, an identification circuit for identifying the type of chrominance signal supposed to appear in each horizontal scanning period of the reproduced signal, and a selector for selecting one of the reproduced signal and the output signals from the 1H delay circuits in response to a combination of an output signal from the identification circuit and output signals from the latches so as to cause the identified type of chrominance signal to appear in the horizontal scanning period of the selected output signal.
