Video communication with QoS guarantees over HIPERLAN/2
Ji Wang, Ashfaq Khokhar, V.K. Garg · 2003
This paper examines the impact of different physical modes on network QoS parameters such as throughput, bit error rate, and retransmission delays. An efficient technique for the transmission of MPEG-2 bit stream over HIPERLAN/2 networks is presented that exploits the hierarchical structure of the MPEG-2 bit stream. We show that for a given video bit stream use of multiple modulation schemes chosen based on the characteristics of underlying video data yields superior throughput and better picture quality in terms of PSNR.
