ERMSCT: MPEG-7 BASED DIDACTICAL AV COURSEWARE BUILDING TOOL FOR HETEROGENEOUS TERMINALS

Now video courseware is not adaptive to heterogeneous terminals, and its description metadata is too much simple to efficiently and effectively search, store, and evaluate the teaching quality. For much redundancy and domain-knowledge in the didactical AV and the maturation of MPEG-7[1][2], we have implemented ERMSCT that can analyze the didactical video content, produce two variations of it for heterogeneous terminals, as well as annotate with MPEG-7. The purpose of this paper is primarily twofold. The first purpose is to how to use MPEG-7 to design the description scheme about the didactical AV. The second purpose is to show how efficient and effective the video courseware created by content-based multimedia analysis is.
