摘　　要：随着互联网技术与视频会议技术不断深入的发展,视频会议正在以全新的面貌给人们带来方便、简洁、高效、真实的沟通体验,当前基于Web的视频会议已经成为炙手可热的研究热点。基于在线教育系统项目中开源Web视频会议系统Bigbluebutton的语音架构,针对该系统语音处理的效率比较低的问题提出了一个新的语音架构优化方案,使参与会议的所有听众只占用一个语音发布流通道,从而大幅降低会议系统的语音通道数量,降低视频会议系统对资源的消耗。同时给出了该方案的实现细节。With the development of internet and video conferencing technology,video conference is providing people with convenient,concise,efficient and authentic communication experiences in a new appearance. Meanwhile,the web- based video conference is becoming a research focus. The voice architecture of the web video conference system- bigbluebutton which employed in our online education system is analyzed. An optimal voice architecture is proposed to improve efficiency of the voice processing. It only uses a voice publishing channel to handle all the participants who only listen the conference. The solution can evidently reduce number of voice channels for a conference and thus reduce IT resource consumption. The detail of realization is also provided.
