On video coding algorithms with application level QoS guarantees
To transfer video streams with the application level QoS (Quality of Service) 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 speci ed 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 modi cation to the VBR intra-slice coding algorithm. The proposed algorithm is e ective to achieve smaller end-to-end delay by applying the doubled quantizer scale to the rst picture. Key words: QoS, MPEG-2, intra-slice coding, bandwidth allocation
