Synonym of D2 (video format)

For other uses of the name D-2, see the disambiguation page.

D-2 is a professional digital video tape format created by Ampex and other manufacturers through a standards group of the Society of Motion Picture and Television Engineers (SMPTE) and introduced at the 1988 NAB (National Association of Broadcasters) convention as a lower-cost alternative to the D-1 format. Like D-1, D-2 video is uncompressed; however, it saves bandwidth and other costs by sampling a fully-encoded NTSC or PAL composite video signal, and storing it directly to magnetic tape, rather than sampling component video. This is known as digital composite.
