Statistical properties of MPEG video traffic and their impact on bandwidth allocation in wireless ATM networks

In this paper, we analyse the statistical data sets of several MPEG encoded videos and propose a model of the elements of a scene. The proposed model permits the characterisation of the elements of the stream scenes. The model can be used to allocate bandwidth dynamically on a scene basis and will result in a high capacity gain while guaranteeing the same and even better QoS. This model is particularly suited for MPEG encoded VBR traffic in wireless ATM networks.
