Research And Implementation Of Real-time Virtual Classroom Based On Streaming Media

Education is the foundation of the revitalization of Chinese science and technology. Atthe same time, science and technology boosts the progress of the education. The rapiddevelopment of information technology makes it possible to implement distance educationwith the help of computer technology and network technique, breaking the limitations of timeand space, sharing teaching resources, shortening the gap of the teaching standard. But peoplestart not to satisfy with the current text-interaction and resources downloading. There is agrowing demand for multimedia information, and people are more and more eager to be ableto have real-time communication over the network. The advent of streaming mediatechnology makes real-time interaction to become reality.This paper studies the way to achieve real-time interactive distance learning platform-real-time virtual classroom using streaming media technology, computer technology andnetwork technology. The system extends from the core functionality of the virtual classroom.Virtual classroom simulates the traditional classroom to meet the demand of the interactionbetween teachers and students in a real classroom. It provides text-interaction, video, audio,shared blackboard, shared documents, group discussion and other functions and simulates aface-to-face teaching impression for teachers and students via the audio and video. Itimplements unified browsing and synchronized operations function of documents. In additionto the virtual classroom module, the system provides external auxiliary modules, includingclassroom resource management module, personal information management module, studentuser management module, as well as teacher user management module.This paper introduces the research background, current status and existing problemsfirstly, clear the significance of this paper and gives the general framework of the thesis. Thenit studies relevant theory, including the basics of the virtual classroom and the relatedconcepts of streaming media, defining the streaming-media-based virtual classroom.According to the system requirements for real-time virtual classroom, this paper establishesthe overall objectives and design principles, build system architecture, analyze and designfunctions of each module. A real-time virtual classroom system based on the FLEX+RED5isbuilt finally.
