✦ Synopsis

To transfer video streams with the application level Quality of Service (QoS) guarantees on the end-to-end transfer delay and the video quality, the coding algorithm and parameters should be determined appropriately considering network conditions. In this paper, by comparing four coding algorithms specified in MPEG-2 through simulation experiments, we show that intra-slice coding algorithms outperform the others in the video transfer over the statically allocated bandwidth. We further introduce an easy and straightforward modification to the VBR intra-slice coding algorithm. The proposed algorithm is effective to achieve smaller end-to-end delay by applying the doubled quantizer scale to the first picture.
