A Research On Video Processing And Scheduling Technology Of Multimedia Distance Trainging System

With the development of multimedia communication technology, multimedia technology and computer technology combines and distance training is becoming more popular than ever before.China is playing an increasingly important role in the stage of the world economy, which will lead the demand for people of high caliber to a change in the way of traditional education. The traditional way of education using books have been impossible to meet the needs of more convenient way of education.However distance training makes it easier to break through time and space constraints, to help people more easily learning, which contribute to education socialization and learning socialization. From the perspective of enterprises and institutions, Internet-based distance training, effectively reduce the travel costs of the staff who attend the training, while increasing the totalbenefits of investment in training and expanding the training feedback and training frequency. Enterprises can also make a more flexible training programs based on actual demand for staff. Distance training system generally provides synchronous training and asynchronous training in two main ways through live online training and on-demand training combined with multimedia courseware. Due to the shortage of network architecture for enterprises and institutions in remote training deployment, how to achieve streaming media scheduling strategy, synchronous training and asynchronous distance training system in such network architecture has important theoretical and practical significance.Firstly, based on the distance training system requirements analysis, the structure model and function model of the system has been proposed. Then, on the basic of principles of live synchronous training, a streaming media server for push broadcast model has been proposed, then a way of multimedia courseware producing based on the timeline model and event-driven mechanism, after researching the multimedia courseware conversion, synchronization of video and multimedia courseware and video editing has been proposed, a streaming media scheduling strategy based on principle of CDN has been proposed after some work on the CDN distribution network. At Last, System has been achieved on Asp. Net, Winform, and Silverlight three technology platforms using unified C#language.
