摘要
基于目前网络教学缺乏良好互动模式的情况,提出建立实时视频教学系统,为师生搭建面对面的沟通平台。对目前实现实时视频的Web RTC,HTML5,Web Socket和Node.js等关键技术进行了深入研究,构建基于Web RTC技术的B/S模式的实时视频教学系统,实时视频交互模块的通信选择全双工通信的Web Socket协议。系统可运行在任何支持HTML5的浏览器上,实现跨平台视频交互教学,充分提高学生的学习积极性。
Since the network teaching lacks of good interactive mode,the establishment of real-time video teaching system is proposed to build the face to face communication platform for teachers and students. The key technologies of Web RTC,HTML5,Web Socket and Node.js to realize the real-time video are deeply studied. The real-time video teaching system based on B/S mode of Web RTC technology was constructed. The Web Socket protocol of full-duplex communication is selected for communication of the real-time video interactive module. The system can run on any browsers supporting HTML5,realize the video interactive teaching with cross-platform capacity,and improve the students＇ learning initiative greatly.
