Abstract
A transcoder system for compressed digital video bitstreams comprising the three frame types: I-frames, P-frames and B-frames, is disclosed. The system includes a picture reader decoder to ascertain and select the type, size or estimated quality of each frame, or the DSP processing power of each frame prior to transcoding. The system also includes a Ttranscoder for processing B-frames and a picture decision block for separating all I-frames and P-frames from B-frames in the case where the frame type is selected. Another component is a remerge block for recombining the output of B-frames from said Ttranscoder with the untranscoded P-frames and I-frames into a reconstituted output bitstream, such that only the B-frames are processed by the much faster Ttranscoder, thereby achieving substantial improvement in the transcoding throughput speed.
