摘要/Abstract

摘要： 针对实时多媒体在IP网络上的传输,首次提出了两种基于实时传输协议的MPEG视频源的建模:一种是考虑不同类型帧之间的相关性以及I帧的特殊性,对I帧采用Gamma分布建模,对P、B帧采用相对于I帧的合成回归模型分别建模;另一种是分别对I、P、B帧采用Gamma分布建模。通过计算机模拟实验,验证并比较了两种模型的有效性。

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.
