提出了一种新的基于空间更新过程（SRP）和多项分布（MM）的帧级MPEG-4 VBR视频业务模型。现有的帧级模型往往忽略了I、P和B帧之间的相关性。相比之下，所提出的模型利用相关性来提高模型的准确性。仿真结果表明，该模型能够准确预测丢包性能。
A new frame level MPEG-4 VBR video traffic model which is based on spatial renewal process (SRP) and multinomial distribution (MM) is proposed. Existing frame level models often ignore the correlation between I, P and B frames. In contrast, the proposed model utilises the correlation to improve the model accuracy. Simulated results show that the proposed model predicts packet loss performance accurately.
