| 摘 要： | 针对目前Linux系统下虚拟实时课堂系统的缺乏，提供了一种基于国产Linux-NC的虚拟实时课堂系统的设计方案，并给出了详细的实现流程。系统主要利用免费开发包JMF2_1_1e（Java媒体框架）来实现，NC终端采用远程登陆方式，简化了开发流程。本系统摆脱当前Windows-Intel平台的垄断方式，不仅能够降低软硬件成本、满足边远贫困地区的远程教育的需求，亦推动了国产软硬件的普及和发展。

| Abstract: | Aim at the shortage of the virtual real-time classroom system under Linux at present,a design scheme as well as detailed re-alizing flow about virtual real-time classroom system based on domestic Linux-NC is provided.JMF(Java Media Framework),a kind of free development kit,is the main technology measure in this system.Development flow was simplified by using Telnet way in NC terminal.Shaking off present monopoly of Windows-Intel,this system can meet the needs of outlying poverty-stricken regions and remote education in a low-cost way,and the popularization and development of the domestic software and hardware are also promoted. |
