S-Video

Separate video, abbreviated S-Video and also known as Y/C (or erroneously, S-VHS and "super video") is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries high-bandwidth 480i or 576i resolution video, i.e. standard definition video. Component video cables are commonly used to carry bandwidths over the resolutions supported by a S-Video cable (for example, a component video cable can easily handle 576p, 760p, 1080i and 1080p) and many devices will commonly have both S-Video and component video inputs (along with the composite video input). S-Video does not carry audio on the same cable.

<multimedia> A video format offering a higher quality signal than composite video, but a lower quality than component video. This mid-level format divides the signal into two channels - luminance and chrominance.
