Linux下基于MPEG4IP的实时授课同步技术和实现方法

AN IMPLEMENTATION METHOD OF THE LINUX-MPEG4IP-BASED REAL-TIME TEACHING SYNCHRONIZATION TECHNOLOGY

从多媒体通信中的关键技术媒体同步技术入手,提出了一种以GNU Linux为运行平台的实时授课系统的同步技术和实现方法。该授课系统以MPEG4 IP流媒体处理平台为基础,实现了教师授课视音频和授课屏幕数据三种媒体从采集、传输到回放的同步功能。围绕上述三个方面进行展开,重点阐述了同步的实现机制和开发技术。最后,总结了研究工作,并阐述了下一步的研究改进方向。

From the perspective of multimedia communications synchronization technology, a real-time teaching synchronization technology and its implementation method are introduced and deployed under the Linux-based real-time teaching system. The system is based on MPEG4IP streaming media development kits to realize a series of functions,including capturing, transferring and simultaneously playing back of the teaching audio, video and screenshot data. According to these three functions, the main implementation mechanism and development method of the multimedia synchronization technology are described. Finally, a summary of the relative research work is given and the further technological improvement direction is pointed out.
