In professional editing environments, composite video signals are most commonly used

for troubleshooting, for menu outputs, and for low-quality preview monitoring. For

consumer and home use, composite signals are often used to connect VCRs or DVD

players to televisions.

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 a composite video

image 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. Use care when working with S-video connectors; the

four delicate pins can be bent easily.

Component YUV and Component RGB

Professional video equipment, such as Betacam SP decks, has component YUV (Y′C

)

video inputs and outputs. Component YUV separates color and brightness information

into three signals, which keeps the color quality more accurate than that of other systems.

Component YUV is as good as analog video gets. High-end consumer devices, such as

DVD players and televisions, have increasingly begun to support component YUV.

Note: Another form of component video, component RGB, is not as widespread on

professional equipment 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”) to send

a timing signal. Sync can also be embedded in the Y or G part of the signal (using three

connectors), a separate composite signal on a fourth connector, or separate H and V drive

signals (using five connectors). See your equipment’s documentation for more information.
