摘　　要：针对现有远程教育系统中,网络视频会议系统在线录制的缺陷,基于开源bigbluebutton项目设计了一个在线录制与回放的方案。该方案由用户按需自主控制录制,系统自动发布,扩展了bigbluebutton的功能,促进该开源项目在远程教学中的应用。对视频会议中录制与回放功能的优化,可以进一步完善实时教学和非实时自学、评估等过程,从而满足人们日益增长的教育需求。In view of the defects of online recording in present network video conference system for the distance learning field,this article develops an online recording and playback module based on the open source project：bigbluebutton. It provides the on-demand self-control reeording services for the users,as well as the function of automatic release by the system. The project expanses the bigbluebutton functions and promotes the application of the open source project in distance learning. The recording and playback functions optimized for video conferencing can further improve the real-time teach- ing and non-real-time self-assessment process, and further meet the growth in demand for education.
