The Research Of Streaming Media Courseware And Application System Based On Web

With the rapid development and wide application of network technology and computer technology ,Web- based multimedia long-distance education development to the traditional educational methods have brought profound changes. At the same time, Most of people have been educated equally and well, which is good base constructed Science Development notion and harmonious community. Now, Web-based long-distance educational contents have varied from traditional multimedia courseware to Streaming Media Courseware all over the world. The chance is not educational form but educational methods. Streaming media courseware on demand system as part of long-distance education,has integrated real-time and non-real-time,Which is complex,distribution and ensure the long-distance education has become a powerful accessional means and extension of traditional education. So the research of Streaming media courseware and application on long-distance education is significances of theory and values of application. It is fit in with the needs of the modern education theory and teaching.Now, some multimedia courseware on demand systems or live system exist in land and overseas,but there are many shortcomings and deficiencies,such as immoderate human interface design, difficult uploading , low quality and playing speed of courseware etc. So they can not meet the long-distance needs. In the light of the existing problems of courseware on demand system,text has in depth researched on the basis of relevant literatures and research results,made the corresponding solutions,and on this basis to implement Streaming Media Courseware on facture and playing system. Through the operation of the certification,system has the advantage and feasibility. The text resolves following questions. The first, solving the limit of recording and uploading on network, now every teacher can record and upload his courseware on Internet by ActiveX technology of C#. Secondly, overcomeing the limit of line-searching courseware and incompatibly playingcourseware, students can study expediently on Internet through courseware on demand system. The system with friendly study plat makes playing tree automatically on specialty or course by ActiveX technology of C#, database technology and videodisplay-embedded manage technology. Thirdly, text solves streaming encoder and multi-stream synchronization by in depth researched technology of Windows Media SDK. Fourthly, By C# language, database technology etc, text provides a managing and studying flat. After loading in, users can do something, such as kinds of role manage, registration manage, excellent course recommendation manage, bulletin-information manage, uploading courseware, specialty manage, forum manage, vote manage etc. Finally, text provides information flat including excellent course recommendation, information bulletin, all kinds of information searching, course vote, forum etc. To implement playing and managing courseware on Internet,the system applies B/S model framework, which divides system into three parts, based on software system structure. System provides user-friendly interface, exact navigation, all-sided function and good experiences to medium-sized and monotype organization to establish a long-education system on demand.In the end, paper for the work carried out summary,prospected the streaming media courseware on demand system applications, and indicated that further research directions.
