摘要

本文研究了不同物理模式对网络QoS参数(如吞吐量、误码率和重传延迟)的影响。提出了一种在HIPERLAN/2网络上传输MPEG-2比特流的有效技术，该技术利用了MPEG-2比特流的分层结构。我们表明，对于给定的视频比特流，使用基于底层视频数据特性选择的多种调制方案可以在PSNR方面产生卓越的吞吐量和更好的图像质量。

Video communication with QoS guarantees over HIPERLAN/2

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.
