) 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.
FireWire (Also Called IEEE 1394a or i.LINK)
This is the consumer and professional standard for DV-format digital video. FireWire is
an inexpensive and easy way to capture and output high-quality digital video using a
variety of camcorders and decks, 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.
