Abstract

"This paper describes a model for rate prediction in video transcoding applications. The model is based on a log-linear approximation of rate-quantisation characteristics. It is shown that such a model is capable of accurately predicting the rate of transcoded pictures, given one R-Q point derived from the original coded signal. Its application in mobile multimedia communications where hard transcoding is required, is also discussed in the paper."
