Abstract
A transcoder system for compressed digital video bitstreams comprising three frame types: I-frames, P-frames and B-frames. The system includes a picture reader decoder to ascertain the type of each frame prior to transcoding. The system also includes a Ttranscoder for processing I-frames and P-frames, possibly excepting the last P-frame of a group-of-frames (GOP), a Ttranscoder for processing B-frames and (optionally) the last P-frame of a GOP and a picture decision block for separating all frames into I-frames and P-frames, possibly excepting the last P-frame of a GOP for processing by the Ttranscoder and B-frames and (optionally) the last P-frame of a GOP for processing by said Ttranscoder. Another component is a remerge block for recombining the output of all frames from said Ttranscoder and the Ttranscoder into a reconstituted output bitstream, such that most of the frames are processed by the much faster Ttranscoder, thereby achieving substantial improvement in the transcoding throughput speed while retaining a low error rate.
