Markovian models for the output of real word MPEG-1 encoders
Date Issued

Abstract
In this paper we survey the output of real world MPEG-1 encoders. This output consists of packets whose sizes are multiple of 20Kbytes, while the arrival intervals are mainly gathering around 220 msec. Two markov models are proposed. The rst model, which is called model A, takes into account only the packet sizes ignoring the arrival intervals. The second model (model B) quantizes the arrival intervals so as to better approximate them. Finally a combination of the two models is proposed (hybrid model) so that it
can better approach the tra c behavior.
