发明名称 METHOD FOR HYBRID DISTANCE LEARNING THROUGH INTERNET AND CD-ROM
摘要 PURPOSE: A method for a hybrid distance learning through the internet and CD-ROM is provided to support an effective distance learning based on the interactive interface function of the internet and the high capacity storage function and simple driving of the CD-ROM. CONSTITUTION: A learner who registered an ID and class code in advance accesses a web server by using a browser and logs in(101). After the log-in authentication procedures(103), the user moves to a contents server(105). The contents server automatically checks the access speed of the learner when providing the high capacity contents service(201). If the access speed of the learner represents over 100kbps, the contents server let a media server perform a streaming service(301). The media server transfers the moving image data for education to the learner in real time streaming way(301). If the access speed represents below 100kbps, the contents server checks whether the moving image file for education exists in the CD-ROM of a client(PC of a learner)(203). If there is the file in the CD-ROM(205), the learner PC transfers an authentication server the file execution data together with the ID and class code in Secure Socket Layer type(207). After checking the ID and class code of the learner(401), the authentication server transfers the authentication result to the media server(403). The media server checks the class data of the learner(303) and transfers a learner PC a release key removing the blocking data of the file within the CD-ROM(305). After removing the blocking data of the file through the release key at the learner PC, the learner runs the file for education and gets the service(501).
