Abstract
Variable bit rate (VBR) video will be the predominant application in the future’s multimedia communication networks. Understanding the characteristics of VBR video is important for us to utilize network resources effectively. A brief description of MPEG-1 video sources is given. The essentials of self-similarity and long-range dependence are also presented. Furthermore, some methods of estimating Hurst parameter are described in details. We analyze an hour-long MPEG-1 video trace, and the details of statistical results are discussed. The results highlight that the trace generated by MPEG-1 code has both the short-range dependence and long-range dependence structures.
