component video

A color video format that maintains the three traditional YUV video signals in separate channels. Component video provides a sharper image than composite video and S-video. See YUV, composite video and S-video.

Analog Component Video
With regard to TVs, DVD players, cable boxes, receivers and related A/V equipment, component video generally refers to "analog" component video. The connection comprises three wires identified as Y, Pb and Pr (see YPbPr). Component video cables come in three-wire sets (see below), or five-wire sets, which include two more wires for analog audio.

Digital Component Video
Component video may also refer to "digital" component video (YCbCr) for digital camcorders. The connection uses one cable, typically FireWire or SDI, and is natively supported by many nonlinear video editing programs (NLEs). Digital component video is also carried over HDMI. See YCbCr and chroma subsampling.

Analog RGB
Sometimes, component video means RGB signals rather than YUV and may refer to a three-wire analog RGB cable for a studio monitor or high-end video camera. See RGB.



Analog Component Video (YPbPr)
Analog component video uses three-wire cable sets for A/V equipment. Five-wire sets bundle left and right stereo (red/white) wires in the cable.
