Abstract: A fast algorithm is developed for direct conversions between the 2-4-8 DCT mode associated with the digital video cassette (DVC) standard and the ordinary 8-8 DCT associated with other formats of compressed video. The algorithm avoids explicit transformations to and from the original pixel domain and thus saves a considerable amount of computations.
