摘要:
传统对等视频会议系统对网络和硬件条件要求较高,容易导致视频会议交互质量较差.针对这个问题,本文提出一种适用于单一时刻关注目标数小于参与者总数时(如移动端会议)的对等视频会议模型(WebRTC based video conference model,WVCM).该模型基于WebRTC媒体处理引擎,减少同时关注的目标数,使用少于传统模型的资源消耗就达到了与传统模型相当的规模,并通过目标加入和退出算法实现对会议中所关注目标的快速切换以及模型的维护.实验结果表明,WVCM能在保证会议质量的前提下有效减少网络流量并扩大会议规模.
Abstract:
Traditional peer-to-peer video conference system has very high requirements for both network and hardware condition,which causes the quality of video conference to degrade.To improve this situation,a WebRTC Based Video Conference model,WVCM,is proposed in this paper.This model can reach the same scale as traditional conference model with lower resource cost by reducing the amount of targets observed at the same time.Then,a target joining and leaving algorithm is introduced to enable quick target switch.These features make WVCM very suitable for the situation,such as mobile conference,where conference participants are more than targets to be watched simultaneously.Experiments show that WVCM can reduce traffic and scale up the conference without harming service quality.
