摘要
在流媒体网络传输中,如何降低媒体流的误码率和提供更好的媒体质量一直是流媒体研究所关注的焦点问题。本文在分析比较各类算法后,提出了一种适用于无线网络中的快速自适应实时流媒体控制算法,该算法能快速获取当前网络情况,并在保证媒体流质量稳定的前提下,非常快速、准确地调整发送端的媒体流速率。实验表明,该算法能够在不稳定的网络环境中大幅降低媒体流的误码率,并提供更好的媒体质量。
How to keep error rate low and provide better media quality in streaming media transmission is the hotspot for study.A quickly adaptive real-time multimedia streaming control algorithm is proposed based on the analysis of various existing algorithms.The proposed algorithm can be used in wireless network environment.It can quickly acquire the network situation and adjust the sending bit-rate at the same time to ensure good media quality.Experiment and simulation results show that the algorithm can keep very low error rate and provide much better media quality in unstable wireless environment.
