Composite cable

Description

Composite, the oldest of video signals and still prevalent, combines both color (chrominance) and black and white (luminance) in one signal. This feature originally allowed for backwards compatibility with black-and-white televisions receiving off-air broadcasts, but created image problems not found in later S-Video or component signals. Today, a typical composite video signal uses a single coaxial wire, a yellow RCA connector for video, and a white and red RCA connector for stereo audio. A BNC connector is frequently found in professional applications.
