Abstract

PURPOSE: To record and reproduce the video signal with good S/N and to reduce the effect of time axis variation, by constituting the interleaved chroma signal to obtain other signal through the filtering of Y type comb filter.
CONSTITUTION: Among the color video signal constituted with three types of video signals, the color video camera 2 sectiones one type signal Y and two types of signals . and Q, and one signal Q is inverted 5 every 1H and it is added 6 to other signal I, obtaining the interleaved chroma signal. It is recorded in the recording media and at reprodution, the reproduced interleaved chroma signal is filtered in the C type comb type filter 18, allowing to obtain one signal Q and the interleaved chroma signal is filtered in the Y type comb type filter 16, allowing to obtain another signal I. With this constitution, three types of video signals constituting the color video signal is recorded and reproduced with good S/N and the effect by the time axis variation can be reduced.
