Component YUV and Component RGB
Professional video equipment, such as Betacam SP decks, has component YUV (Y

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.

FireWire 400
FireWire 400, also called IEEE 1394a or i.LINK, is the consumer and professional standard
for formats such as DV, DVCAM, DVCPRO, DVCPRO 50, DVCPRO HD, and HDV. FireWire is
an inexpensive and easy way to capture and output high-quality digital video using a
variety of camcorders and decks and is capable of data rates as high as 400 Mbps. Standard
FireWire cables can be up to 4.5 meters long.
There are two kinds of FireWire connectors: a 4-pin connector (typically found on video
equipment such as camcorders or decks) and a 6-pin connector (used for computer
equipment). However, some newer video equipment uses the 6-pin connector, and some
video interfaces use the 4-pin connector. See your equipment’s documentation for more
information.
