Abstract

Most previous research efforts on video transcoding have been focused on changing the bit-rate of one pre-encoded bit-stream to another. However, in many applications (e.g. streaming video over a heterogeneous network), it may require to transcode a pre-encoded video bit-stream to multiple bit-streams with different bit-rates and features to support multiple clients with different requirements. In this paper, we discuss the case of point-to-multipoint transcoding. We compare two transcoder architectures in terms of processing speed for H.263 and MPEG-2 transcoding. We show that for point-to-multipoint transcoding, a cascaded video transcoder is more efficient since some parts of the transcoder can be shared by the multiple clients.
