该论文提出使用无线带宽管理架构来增强 HTTP 上的自适应视频流。该架构通过向视频客户端提供额外的网络侧控制信息来强制对视频比特率自适应进行分布式控制，以帮助他们做出决策。由于跨层信令框架，该架构和所包含的分布式决策算法具有网络和服务感知能力。本文提出了一种基于 MPEG-DASH 的架构测试台实现，并在两个网络辅助视频自适应用例的背景下研究了其性能。使用测试台进行的实验评估获得的结果证明了所提出的解决方案相对于最先进的客户端方法的优势。
The paper proposes enhancements to adaptive video streaming over HTTP using a wireless bandwidth management architecture. The architecture enforces distributed control over video bitrate adaptation by providing additional network-side control information to video clients in order to assist them in their decision-making. The architecture and included distributed decision algorithms are network and service aware thanks to a cross-layer signaling framework. The paper presents an MPEG-DASH based testbed implementation of the architecture and studies its performance in the context of two network-assisted video adaptation use cases. The results, obtained in an experimental evaluation conducted using the testbed, attest the benefits of the proposed solution against a state-of-the-art client-side approach.
