    The requirement of automatic video summary is increasing as bi-directional broadcasting contents and various user requests and preferences for the bi-directional broadcast environment are increasing. Automatic video summary is needed for an efficient management and usage of many contents in service provider as well. In this paper, we propose a method to generate a content-based summary of linguistic educational videos automatically. First, shot-boundaries and keyframes are generated from linguistic educational video and then multiple(low-level) visual features are extracted. Next, the semantic parts (Explanation part, Dialog part, Text-based part) of the linguistic educational video are generated using extracted visual features. Lastly the XML document describing summary information is made based on Hierarchical Summary architecture of MPEG-7 MDS(Multimedia Description Scheme). Experimental results show that our proposed algorithm provides reasonable performance for automatic summary of linguistic educational videos. We verified that the proposed method is useful for video summary system to provide various services as well as management of educational contents.
