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. Reference: http://www.wikipedia.com
