摘　　要：可视化、智能化、交互性是现代远程教育发展的趋势。流媒体具有低消耗,高利用率的特点。而MPEG-4是一种高度结构化的高效编码方式,非常适合复杂网络环境下流媒体的编码传输。本文给出的方案不仅发挥了流媒体和MPEG-4的优势,还解决了现有教育资源(图片、F lash、PPT等)重利用的问题,具有很强的应用价值。Visualization, intellectualization, interaction are the trend of E - Learning. Streaming multimedia is low consumptive and high profitable and MPEG -4 is an efficient, high structured coding technique, which is suitable for streaming multimedia coding and transport in complex networks. In this dissertation, we give a scheme which not only brings into play the advantages of streaming multimedia and MPEG - 4, but also solves the problem of resource reuse in E - Learning.
