Understanding Digital Video (DV)
DV refers to digital video that is transferred through equipment
conforming to IEEE Standard 1394. This equipment (cameras, decks,
cables, connectors, and processing boards) is sometimes referred to as
FireWire® or I-Link™.
DV connections let you transfer digital data (both video and audio)
directly from a DV camera to a digital nonlinear editing system with
no conversion losses. DV technology simplifies the process of bringing
footage from your camera into your Avid NewsCutter XP system, and
gives you high-quality video at low lost.
What Is IEEE Standard 1394?
IEEE 1394 is an internationally standardized, low-cost digital interface
that integrates entertainment, communication, and computing
electronics into consumer multimedia. IEEE 1394 is a hardware and
software standard for transporting data at 100, 200, or 300 megabits
per second (Mb/s). Because it’s a digital interface, there is no need to
convert digital data into analog, resulting in a loss of data integrity.
What Is DV?
Digital Video (DV) is an international standard created by a
consortium of 10 companies to serve as a consumer digital video
format.
DV, originally known as DVC (Digital Video Cassette), uses a 1/4-inch
tape to record very high-quality digital video. The video is sampled at
the same rate as D-1, D-5, or Digital Betacam video (720 pixels per
scanline), although the color information is sampled at the D-1 rate
4:1:1 in 525-line (NTSC) and 4:2:0 in 625-line (PAL) formats.
