Component cables


S-video female connector

S-video splits the video signal into two pieces: chroma (color) and luma (brightness). Chroma and luma are sometimes abbreviated by the letters C and Y, respectively.

Pin Assignments
Pin 1 Ground (Luma)
Pin 2 Ground (Chroma)
Pin 3 Luma
Pin 4 Chroma


Yellow RCA cable

Composite video combines the chroma and luma signals of s-video into a single signal. It is most commonly transmitted using an RCA cable, usually with a yellow connector, and is often grouped with red and white audio RCA cables. The inner pin carries the video signal, and the outer ring is ground.

SCART is also capable of carrying composite video. It's also known as CVBS(Color, Video, Blanking, and Sync).
