Abstract
A method and apparatus for transcoding a digital video signal is described. A first set of bits encoded in a first encoding format are received. The first set of bits are decoded to discrete cosine transform (DCT) coefficients. The DCT coefficients are transformed into an intermediate exchange format. The transformed DCT coefficients are encoded using a second encoding format.
