Based On The Online Streaming Media Technology Aided Teaching System Design And Research

The application of Flash media techniques in web teaching enables a conversion of traditional teaching mode into a vivid film mode,as well as radio teaching,audio-video teaching,teaching demonstrations,messaging,web theatres, remote 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 time and space.In this paper,the content can be logically divided into the following five parts:The first part is the introduction:including the proposed issue to study the significance of the development of online teaching,research papers,UML modeling of the advantages and disadvantages;The second part is online supporting the theoretical basis for teaching:teaching theory including the elements to build,on-line design features to support teaching,object-oriented concepts,logic modeling process;The third part is the technical support of online teaching,including traditional streaming media technology, FMS streaming media services,the application layer of the Transmission Control Protocol,FMS communication components,Flash Remoting MX;fourth part is: online-aided teaching systems analysis and design:including online-aided teaching system needs analysis,system UML basic model,the system type of design,system architecture model,database design;the fifth part is:online-assisted teaching system to achieve and summed up:the system is to achieve with the presentation,system innovation and the characteristics of the full text of a summary and further research.Based on the constructive teaching theory,we focused on the characteristics of web teaching,and,discussed the relevant protocols and utilizations of the traditional mainstream Flash media technology in combination with the development in audio-video technologies in this paper.In compare to the features of traditional Flash media technologies,we introduced a new developmental technology that is Flash Media Server(FMS) which not only has Flash video but also is capable of developing interactive executive programs.We used and studied the application of FMS with audio and video technologies transmitted synchronously in real-time dynamic audio teaching system.By using UML modeling to analysis and design the system,major functions and methods of realization have been introduced as well as certain application and creativity of this system. This article is about the theory of knowledge and new technologies into practical projects,and through on-line system to support teaching and research to analyze the design for the online mode of teaching aids to provide a new direction of development.
