| 摘 要： | IP分组网和无线网的多媒体业务是未来的主流,传送实时的视频流是多媒体应用的主要内容,传送实时的视频业务有带宽、延时、包丢失的要求,但是因为IP分组网和无线网的固有特性不提供QoS保证,另外网络的不对称给组播业务带来了实际困难,因此分析了IP分组网和无线网对于实时视频流的质量影响因素,研究了基于网络和终端的解决方案,并着重研究了基于终端解决方案的策略.

| Abstract: | In the future, most multimedia service is based on IP network and wireless network. Delivering real lime video stream is important component of multimedia application, Transmission of real time video has bandwidth, delay, loss requirement ,but IP network and wireless network do not offer QoS guarantees to video transmission, and the heterogeneous communication is stil] a challenge in multicast. In this paper,the authors analyze the properties of IP and wireless network, and research into the strategy of solution based on IP and wireless network. Because the practicable strategy is based on the ternunal of the system,so the authors research into the strategy based on the termina] specially. |
