直播和点播视频流最近贡献了互联网流量的重要部分。为了保证最佳的用户体验，多媒体服务需要支持不同网络条件下的大波动。如今，用于多媒体传送的成本有效的手段之一是HTTP流。该技术的关键挑战是如何根据网络变化和客户端缓冲区自适应地改变视频比特率，同时赋予用户最佳的视频质量。在本文中，我们提出了一种新的速率自适应方法在客户端，它允许客户端估计缓冲区水平在未来，从而实现高视频质量和缓冲区稳定性之间的平衡。实验表明，我们的方法在不同的网络条件下表现良好。
Live and on-demand video streaming has recently contributed a significant part of the Internet traffic. In order to guarantee the best possible user experience, multimedia service is required to support large fluctuations in different network conditions. One of the cost effective means for multimedia delivery nowadays is HTTP streaming. The key challenge of this technology is how to change adaptively video bitrates according to network variation and client buffer while bestowing upon users the best possible video quality. In this paper, we propose a novel rate-adaptation method on client side, which allows clients to estimate buffer level in the future, and thus achieving a balance between the need for high video quality and buffer stability. The experiments show that our method performs well under varying network conditions.
