S-Video
S-Video, also known as Y/C, is a higher quality video signal used by high-end consumer
video equipment. The image looks sharper and has better color than composite video
because S-Video keeps the color and brightness information separate on two cables.
Most low-cost analog-to-digital video interfaces have S-Video as their highest quality
video connector.

) and Component RGB
Professional video equipment, such as Betacam SP decks, has component YUV video
inputs and outputs. Component YUV separates color and brightness information into
three signals, which keeps the color quality more accurate than other systems.
Component YUV is as good as analog video gets. High-end consumer equipment, such
as DVD players and televisions, has increasingly begun to support component YUV.
Note: Another form of component video, component RGB, is not as widespread on
professional gear as component YUV.
Both component YUV and RGB signals use from three to five connectors. You can use
three BNC connectors, plus a fourth (typically labeled “genlock” or “house sync”) for
sending a timing signal. Or, sync can be embedded in the Y or G part of the signal
(using three connectors), a separate composite sync (using four connectors), or
separate H and V drive signals (using five connectors). See your equipment’s
documentation for more information.
