Separate
video, abbreviated S-Video and also known as Y/C (or erroneously, S-VHS and
"super video") is an analog 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 package. S-Video works in 480i or 576i
resolution.
Why
Pre-Install Wires?
A
standard 4-pin S-Video cable connector, with each signal pin paired with its
own ground pin.

Today,
S-Video signals are generally connected using 4 pin mini-DIN connectors using
a 75 ohm termination impedance. Apart from the impedance requirement, these
cables are equivalent to regular mini-DIN cables (like Apple's ADB); these cables
can be used for S-Video transfer if no other cable is available, but picture
quality may not be as good.
S-Video is commonly used in USA, Canada, and Japan, found there on consumer
TVs, DVD players, video tape recorders and game consoles. Almost all TV-out
connectors on graphics cards are S-Video, even in Europe, where the standard
failed to make a significant impact due to the preference of the higher-quality
RGB signal.
Some
particularly cheap S-Video cables are notorious for degrading the signals
considerably, when transmitted across more than 5 meters.
Because
it is very simple to convert S-Video to composite signal (just the logical
merging of the two through a filter is required) or vice versa, many electronics
retailers offer converter adaptors for signal conversion. No conversion will
improve image quality, but will allow connecting to otherwise-incompatible
devices.
S-Video
does not carry audio. Hence, a separate audio connection is required.
