The application of multimedia technology and network technology in education field is one of the hotspot nowadays. Currently, most of the countries, especially the western developed countries, all attach great importance to the development of distant education; In China, R&D on distant education is operated more lately than the above countries, but more rapidly. As distant education, especially distant multimedia education, involves streaming video transimission on the network, and the network condition right now is still not ideal for this transimission, thus how to resolve these problems becomes the work of the paper.Based on the comprehence requirement of the distant multimedia teaching system, we choose the distant teaching mode based on web browser. That is to say, Internet is used as transmitting media to broadcast the multimedia teaching content, operate teaching activity, manage teaching activity, operate online examination and instant Q&A, thus a real integral effective education mode will become true on the network..
