摘要

对基于IEEE 802.16的视频流点播传输技术进行了仿真研究。模拟了一些场景,这些场景代表了此类技术在农村地区的部署。研究发现,IEEE 802.16可以支持9/10个用户同时流式传输典型的电影视频内容,CIF分辨率为24帧/秒,平均速率约为750kbps。此外,该研究还展示了H.264/AVC可扩展视频编码(SVC)和基于缓冲区的拥塞控制算法在自适应视频流解决方案中的实用性

Delivery of on-demand video services in rural areas via IEEE 802.16 broadband wireless access networks
A simulation study of delivery of streaming video on-demand via IEEE 802.16 based technologies is described. A number of scenarios are simulated which are representative of rural area deployments of such technologies. The study finds that IEEE 802.16 can support up to 9/10 simultaneous users streaming typical cinematic video content in CIF resolution, 24 frames/s, at average rates of around 750 kbps. Further, the study demonstrates the utility of H.264/AVC Scalable Video Coding (SVC) and a buffer-based congestion control algorithm in an adaptive video streaming solution
