| Summary: | 碩士 === 國立暨南國際大學 === 資訊工程學系 === 93 === This thesis presents a multimedia objects sharing framework on the basis of Internet News infrastructure (NNTP) to facilitate e-learning content access and distribution. Through this framework, a web-based e-learning system can publish sharable learning objects by posting them to a news server nearby, so that the objects can be automatically spread to world-wide news servers through NNTP forwarding mechanism. Instead of hunting for the desired materials from many different e-learning systems, users can easily access those learning objects from neighbor news servers in a unified way. Moreover, we deal with data redundancy problem which occurs especially when the shared object contains huge multimedia data (e.g., instructor’s speech, image, and video). The experimental result showed that the proposed architecture does not cause data redundancy problem. A system prototype has been implemented in our university to share English lectures with others.
