S Video

S-Video (Separate Video) cable carries luminance, or brightness (Y) and color (C) information separately, rather than as a composite signal (in which all brightness and color information is blended together). When transmitted together, color and brightness information must be extracted from one another by the television, often resulting in picture artifacts such as 'dot crawl' and color bleeding. When used with a DVD player, S-Video cables provide a dramatic improvement in picture quality over composite RCA connections, and should be used if component video connection is not possible.
