ABSTRACT:
A method for recording and reproducing a color video signal having a luminance signal and two difference chroma signals together with a key signal by means of two video tape recorders which are synchronously driven comprises the steps of dividing the two difference chroma signals so as to obtain respective high and low frequency components, recording a first video signal including the luminance signal and the respective low frequency components of the two difference chroma signals, recording a second video signal including the key signal and the respective high frequency components of the two difference chroma signals, both the first and second video signals being recorded in a format for 4:2:2 digital video signal processing by using a 4:2:2 type video tape recorder for each of the first and second video signals, respectively, reproducing the first and second video signals, and combining the reproduced first and second video signals so as to obtain the color video signal and the key signal.
