Hardware Design of Computer Multimedia Network Teaching System

计算机多媒体网络教学系统是为了适应计算机多媒体教学而设计的，它能进行计算机音视频信息的实时传输．它的关键硬件多媒体传输控制卡是用来增强音视频信息并控制其传输的，而视频中继器是为了延长视频信息的传输距离以及连接更多的计算机．

The Computer Multimedia Network Teaching System (CMNTS) has been developed, Because it can transmit audio and video information, we apply it to computer multimedia teaching . The Multimedia Transmit and Control Card (MTCC) is the key hardware of the CMNTS , it amplify the audio and video signal and control the signal transmission . The video repeater is designed to extend the signal transmission distance and to be connected more computers.
