ABSTRACT:
A color video signal mixing system wherein a first separating arrangement separates a first luminance signal from a first color video signal; a second separating arrangement separates a first chrominance signal from the first color video signal; a third separating arrangement separates a second luminance signal from a second color video signal; and a fourth separating arrangement separates a second chrominance signal from the second color video signal. A first mixing arrangement produces a mixed luminance signal from the first and second luminance signal; a selecting device selects one of the first and second chrominance signals; a control facility controls the selecting action of the selecting device; and a second mixing arrangement produces a mixed color signal by mixing the mixed luminance signal and the selected chrominance signal.
