Abstract
Efficient integrated digital video transcoding is described. In one aspect, an integrated transcoder receives an encoded bitstream. The integrated transcoder transcodes the encoded bitstream by partially decoding the encoded bitstream based on a first transform associated with a first media data format. The decoding operations generate an intermediate data stream. The integrated transcoder then encodes the intermediate data stream using a second transform associated with a second media data format. The first and second transforms are not the same.
