摘要
描述一种分享Http Live Streaming流媒体,同时对服务器和播放器透明的播放器中间件HLS-Share。HLS-Share通过手机节点间的协作计算,使手机共享3G网络带宽,减少3G网络流量,加速观看Http Live Streaming流。HLS-Share采用基于事件驱动的方法在本地P2P网络中挑选部分节点作为中继节点负责分享从Internet获取的Http Live Streaming流。通过实验验证了相比于每部手机独立使用3G网络观看视频,HLS-Share在引入极小的CPU使用率的代价下,能够实现共享带宽、加快缓存速度的作用,并且消耗的电量小于前者。
This paper describes a player middleware named as His-Share, it shares streaming media of Http Live Streaming, and is transparent to both the server and the player simultaneously. HIS-Share enables mobile phones nodes share their 3G networks bandwidth and cut down 3G networks flow by cooperated computation between the mobile phones＇ nodes, which speeds up Http Live Streaming watching. HLS-Share selects part of the nodes from local P2P network by using event-driven based means and employs them as the relay nodes in charge of sharing the Http Live Streaming data obtained from Internet. In this paper we verify through the experiment that comparing with each mobile phone watching video in 3G network independently, His-Share is able to realise bandwidth sharing, accelerate the role of cache speed, and has less power consumption than the former at the cost of introducing slight CPU utilisation rate.
