摘要

本文提出了一种新的视频流传输方案,并实现了该方案的原型。该方案旨在为使用移动设备的客户端提供增强的QoS。在该方案中,客户端考虑了各种重要的网络因素来决定其比特率。然后,每当当前比特率必须改变时,它就会发送反馈。基于这些请求,服务器端自适应地调整其视频比特率,以增加服务的可访问性。该方案通过基于http的web服务器实现。

Adaptive video streaming over HTTP
A new video streaming scheme is proposed and its prototype is implemented in this paper. The scheme is designed for providing an enhanced QoS for a client using a mobile device. With the scheme, the client considers various important network factors to decide its bit rate. It then sends feedback whenever its current bit rate must be changed. Based upon these requests, the server side adaptively adjusts its video bit rate in order to increase accessibility of the service. The scheme is implemented through a HTTP-based web server.
