DCT is a digital recording component video videocassette format developed and introduced by Ampex in 1992. It was based on the D1 format, and unlike the uncompressed recording scheme of D1, it was the first digital videotape format to use data compression. Like D1 (and D2), it uses a similar cassette loaded with 3/4" (19mm) width tape.
One of the models of VCR released for the format was the Ampex DCT-1700D.
