Intra-GoP Modeling of MPEG Video Traffic
نویسنده
چکیده
Thanks to the ever growing diffusion of distributed multimedia applications, VBR compressed video traffic is expected to constitute the majority of the B-ISDN network load in the immediate future. At the moment, the MPEG coding scheme is widely used for many types of applications. Therefore, it is crucial to obtain a model for the generation of sequences with the same statistical characteristics of real MPEG traces. In this paper, after demonstrating that intra-GOP correlation has to be taken into account, it is proposed an accurate model allowing the generation of an MPEG-like trace. Moreover, as the MPEG traffic has been demonstrated to be self-similar, the proposed algorithm allows to generate a trace, fitting the SRD and LRD behavior and the probability density function of any given MPEG sequence.
