Base On Flash Desk Of Multimedia Long-distance Teaching System

The distance education is the core element of education informationization infrastructure construction, and it the main part of building the lifelong education. From the traditional videotape, radio and television to the information, intelligence teaching mode today by the network as a platform. The developments of intelligence bring about a vast space for distance education.There is the main teaching system has been put into use: two-way video conferencing systems based on hardware equipment MCU, the teaching system based on application software. The system provides great convenience for distance learning in certain aspects,but there are a number of deficiencies. Main features: the exchange between teachers and students in the distance-learning is not clear, the teachers have difficult in transmit teaching information in real-time or does not flow distance teaching, the cost issue of human and material resources in long distance Teaching, the issue that student learning resources independent in distance teaching.Firstly, construction for the better long distance education platform to tackle the current problems faced by the technology, to develop the long-range education system with low-cost and high efficiency. After a lot of research and analysis, this paper discussed the tele-education framework of the function of the system and technical framework of building Flash-based multimedia platform.Secondly, make FLASH as a platform, and integrate Flash Media Server 2 services, web services, ASP.NET, and other advanced technology of modern network carried out a detailed analysis and the reasonable solution to "real-time audio and video broadcast function modules," and "sync with a live demonstration of the classroom courseware module, "" teaching session, tutoring functional modules "," audio and video recording and demand resources function modules "," management authority with the two-way video communication function module " distance in education media.Then the procedures of these modules has repeatedly conducted the analysis and design of the core code has explained in detail the design of these modules function model, the model carried out a series of tests to achieve good results. Implementation of these features provides a powerful theoretical and technical support for based on the Flash platform, and providing a high efficiency, the end cost, high-quality solutions for solving the technical problems faced by building multimedia Long-distance learning system.Finally, summarizing the work of this thesis prospect of future. The research work of this text would be of certain reference meanings to build the perfectly distance learning system and other application in information exchange or manage.
