DCT
Discrete Cosine Transform (DCT) is an algorithm used for reducing bit-rates in digital images. Also Digital Component Technology. Name given to a series of Ampex digital video equipment and accessories. The Ampex DCT VTR uses a mild form of data reduction (around 2:1) and records onto 19 mm tape cassettes — not compatible with D1, D2 or any other format.
