Composite Video

An analog video signal in which the luminance and chrominance is carried on three wires and contains brightness, color and sync pulse information. Also known as Y-Pb-Pr, in which Y carries the luminance, Pb carries the difference between blue and luminance and Pr carries the difference between red and luminance. Referred to as CVBS (color, video, blank and sync), it is used for NTSC, PAL or SECAM video formats.
