S-video – A video interface standard that carries separate luminance and chrominance sig-
nals, usually on a four-pin mini-DIN connector. Also called Y/C. The quality of S-video is sig-
nificantly better than composite video since it does not require a comb filter to separate the
signals. Most high-end televisions have S-video inputs.
