The correlation function and marginal distribution of multipliers at each layer were investigated in multifractal multiplicative process.Based on the lemmas gained
a new multifractal MPEG-4 video traffic model(PMFM
predict-able MFM)was proposed.By modeling the coarsest coefficients with the auto-regressive(AR) process
PMFM has the ability of traffic prediction that traditional MFM do not have.Furthermore
the model stability and robustness were also improved by changing the way of parameter estimation.
