新颖的实时视频流传输模式

Novel real-time video streaming scheme

视频传输需要消耗大量的带宽和占用服务器的大量计算资源,为了解决同时传输的视频流数目受到限制的问题,提出了一种新颖的视频流传输框架,多个网络视频服务器组成一个组来共同为多个视频流用户提供服务。在此框架下,研究了一个新的问题——最大化视频流,目标是最大化同时传输的视频流数量。设计了一个启发式的高效算法,与传统的几种视频流传输模式相比,该方法可以支持更多的视频流。

Video streaming is a kind of bandwidth hungry applications and demands lots of processing power.To solve the problem that the number of streaming flows may be restricted,a novel video streaming framework is designed,where multiple NVSs （network video servers） form into a server group to collaboratively provide quality services for multiple users.Based on this framework,aiming to maximize the number of simultaneously online flows,a novel problem——maximum streaming flows （MSF） is studied.This problem is proved to be NP-Complete and a heuristic algorithm is designed,which can support more video streamings compared with several traditional solutions.
