Complexity scalable mode-based H.263 video transcoding

While hitrate-reduction video transcoding is a mature research topic, we introduce a irew paradigni for the old prohlein: designing a complexity scalable transcoder where computation can be gracefully traded off with transcoded video quality. Complexity scalability is iniprtant when a time-vaqing number of real-time transcoding sessions must be inaintaiued by the transcoder simultaneously. Wepresent a complexityscalableti-aiscdiiigalgorithm far H.263 based on codiiig niode transition prahahilities. Preliniiialy results are presented to show potential tndeoffs between computation and transcoded video quality in PSNR.
