Conversion between digital video (DV) for digital video cassette recorder (DVCR) and MPEG-2 intra coding is performed in the DCT domain to reduce conversion steps. Multiplying the matrix by transformed data is used for 4:1:1-to-4:2:2 chroma format conversion and 2-4-8 DCT mode to 8-8 DCT mode conversion for parallel processing. M-quant of MPEG-2 rate control is computed in the DCT domain
