The Construction Of The Learning Environment Based On Web Collaborating Realtime Video Interactively

This thesis illustrates in detail the thesis background theroy foundation,desining idea,implementation of quality guarantee system and the key technology adoptive in the development . furthermore, there are some new exploratory and attempt work as follows.1. Based on the designation of this system, the B/S model is adopted to make our clients realize zero installation.2. Through the further study and research of CSCW, we put forward the collaborating study model based on Web multimedia and expound it in detail.3. In dealing with the interactive vision, we adopt two modes: one is point to point, the oth'er is point to multipoint, satisfying diversified demand for interactive collaboration. And we adopt unicast and multicast separately in dealing with the corresponding media transmission.4. A set of tool for preparing lessons is explored, and it provides its directory tree of dynamicly editing function. And its content supports "What You See Is What You Get". Without spreading courseware on Web explored by this tool, other clients can read its content through Internet.This system is carried out by Java program language, and it synthetically used many advanced technologies such as JMF,CSCW, Multicast, Multithread and digital signature, so it is more advanced, available and crossing platform.
