Abstract

A method for optimising the usage parameter control (UPC) of video services in an ATM network is proposed. The video encoder uses a sliding window for its maximum network utilisation without exceeding the declared bit rate at the call setup. At video scene cuts, where the peak bit rates are generated, the coder limits its generated bit rate through a leaky bucket mechanism. The impacts of optimum UPC on both coding and network performance are investigated. It is shown that for video sequences with scene cuts there is an optimum value of peak-to-mean ratio where the network performance is optimised
