In video, a means of video signal coding and decoding in which the brightness information (or luminance, denoted "Y") and the color information (or chrominance, denoted "C") are carried in separate channels, resulting in a higher-quality picture. S-VHS, Hi-8, and Broadcast Video U-Matic video systems use YC. The letters "Y" and "C," as it happens, are also the first two initials of the inventor of the process, Yves C. Faroudj. Also spelled as two lowercase letters separated by a slash, y/c.
