The Research And Application On The Distant Teaching System Based On Streaming Media Technology

The Distant Teaching System is built on the Internet which is constructed through modern information computer and modern education theory. It is a software system which provides comprehension support services for Distant Network Teaching. With the wide implementation of Distant Network Teaching, people pay more and more attention to the development and use of Distant Teaching System. The applica-tion of Streaming media technology in Distant Teaching enables a conversion of traditional teaching mode into a vivid film mode, as well as radio teaching, audio-video teaching, teaching demonstrations, web theatres, distant management, teaching on demand etc. The convenient connection and highly interactive exchange mimic a virtual space of "vis-a-vis" teaching, which facilitate teachers and students in space and time.Based on the Streaming media technology theory, we focused on the characteristics of distant teaching, we discussed the utilizations and protocls of the mainstream Streaming media technology in bombination with the development in audio-video technologies in this paper. In compare to the features Streaming media technology, we introduced a new technology that is Flash Media Server(FMS) which not only is capable of developing interactive executive programs but also has Flash video. Based on the thought of Object, the paper adopts UML for selecting object, and develops the application with FMS. The database is SQL Server2005. The Distant Teaching System is practical.The paper explains the Streaming media technology, Load Balance; introduces the total designs for system, including the goal, principle, the function of system and so on; analysises and designs Distant Teaching System. Drew out the Use case diagram, Object class diagram and Dynamic digram.
