ABSTRACT:
A method and circuits for encoding a color video signal for processing, preferably recording and/or playback of said signal within a limited bandwidth of not more than 3MHz without a separate channel for color information such that one half the sum of two sequential horizontal scan lines of information equals the luminance information of the color video signal and one half of the difference of the said two sequential horizontal scan lines of information equals the chrominance information of the color video signal, wherein a first chrominance signal and a second chrominance signal are contained in two non-overlapping frequency regions.
