Definition:
S-video, which stands for Separate Video, is an analog (non-digital) video signal. Unlike composite video, which carries all the video data in one signal, S-Video carries brightness and color information as two separate signals, hence the name. Because of this separation, video transferred by S-Video is higher quality than that transferred by composite video. S-Video has a variety of uses, including connecting computers, DVD players and VCRs to TVs.
