Exploiting the Temporal Structure of MPEG Video for the Reduction of Bandwidth Requirements
We propose a new bandwidth allocation scheme for VBR video tra c in ATM networks. The scheme is tailored to MPEG-coded video sources that require stringent and deterministic quality-of-service guarantees. By exploiting the temporal structure of MPEG sources, we show that our scheme results in an e ective bandwidth which, in most cases, is less than the source peak rate. The reduction in the bandwidth requirement is achieved without sacri cing any perceived QoS. E cient procedures are provided for the computation of the e ective bandwidth under heterogeneous MPEG sources. The e ective bandwidth strongly depends on the arrangement of the multiplexedstreams which is a measure ofthe degree of synchronization between the GOP patterns of di erent streams. Assuming that all possible arrangements are equi-probable, we derive an expression for the asymptotic tail distribution of the e ective bandwidth. From the tail distribution, we compute several performance measures for the call blocking pr...
