S-video

S-Video

(multimedia)A video format offering a higher quality signalthan composite video, but a lower quality than component video. This mid-level format divides the signal into twochannels - luminance and chrominance.

S-video

(Super-video) An analog color video format that combines the three YUV video signals into two channels. Brightness/luma (Y) is in one channel, and color/chroma (U and V) are in another. S-video provides a sharper image than composite video, but is not as good as component video. See S-VHS, YUV, composite video and component video.

S-video and Composite Connections
Like composite video, S-video connectors are widely used on VCRs, DVD players and receivers. The audio for both composite video and S-video uses common left/right stereo connections.
