IPTV在WiMAX网络上的性能评估研究
Investigate The Performance Evaluation of IPTV over WiMAX Networks
摘要:
在下一代(WiMAX)上部署视频点播(VoD)已成为当前研究的热门主题之一,预计在不久的将来将成为主要的收入来源,而下一代4G上视频流的效率是实现这一点的关键。我们正在考虑的视频流的实时的视频是由不同的H. 264. x编码(H. 264/AVC,和SVC),我们考虑的IP单播提供这种流视频通过WiMAX。我们的方法研究的性能评估的IPTV(VoD)在WiMAX网络。利用OPNET仿真软件对VoD在WiMAX上的性能进行了研究。仿真结果表明,SVC视频编解码器是一个合适的视频编解码器的视频流在WiMAX。
英文摘要:
Deployment Video on Demand (VoD) over the next generation (WiMAX) has become one of the intense interest subjects in the research these days, and is expected to be the main revenue generators in the near future and the efficiency of video streaming over next generation 4G is the key to enabling this. We are considering video streaming for real time video was coded by different H.264.x codes (H.264/AVC, and SVC), and we consider an IP-Unicast to deliver this streaming video over WiMAX. Our approach investigates the performance evaluation of IPTV (VoD) over WiMAX networks. OPNET is used to investigate the performance of VoD over WiMAX. Results obtained from simulation indicate that SVC video codec is an appropriate video codec for video streaming over WiMAX.
