Abstract: In this paper, first, we used Multi-fractal Wavelet Model (MWM) to characterize the MPEG-4 video traces. The model used the Haar wavelet transform and put a constrain on the wavelet coefficients to guarantee positivity. Then, we used first-order, second-order statistical methods and multi-fractal analysis ways to study the main characteristics of the simulated traces . These characteristics include pdf function, LRD, burstiness and the multi-fractal feature of the video traces. At last, we evaluated the model’s performance. Our findings are that: MWM is a simple and useful model for characterizing MPEG-4 video traces. I t can characterize the global statistical characteristics and the multi-fractal feature of the MPEG-4 video traces perfectly. But this model has its default; it exhibits a poor performance when it is applied to the traces with strong burstiness.
