Discrete Cosine Transform

*[videocassette format]* 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 utilize data compression. Like D1 (and D2), it uses a similar cassette loaded with 3...

Discrete Cosine Transform. Mathematical algorithm used to generate frequency representations of a block of video pixels. The DCT is an invertible, discrete orthogonal transformation between time and frequency domain. It can be either forward discrete cosine transform (FDCT) or inverse discrete cosine transform (IDCT). It is part of the JPEG compres...

The Discrete Cosine Transform is performed at the Block layer. For MPEG-2 (ISO/IEC 13818-2), it's specified in the Annex A to the Recommendation. The input of the DCT and the output of the inverse transform (IDCT) are 8x8 matrices of 9 bits/element, while the DCT coefficients are represented in 12 bits (-2048:+2047). DCT is used to remove the spati...
