Abstract: As to the transportation of real-time multimediaon IP network, two models of MPEG video source based on RTP are presented for the first time. One considers the relation between I frame and P, B frames, and Gamma distribution is used to model I frame,while P,B frames are modeled with compound regressive model. The other uses Gamma distribution to model I,P,B framesrespectively. Simulation indicates the validity of the two models, and comparison is made between them.
