项目摘要

National Institute of Multimedia Education was established for joint-use by national, public and private universities, and is conducting research and development into the practical use of broadcasting in higher education. Educational programs are being produced for University of the Air, public university lectures and teacher education, and they are being collected from all over the world for research use. At the same time, many AV materials such as graphics, photographs, slides, used for the production of the educational programs, are archived and stored on a database in order to supply AV resources information to users at higher educational institutions in Japan.The main purpose of our project is to construct a database system for assisting multimedia materials development in higher education. The main research results are as follows.(1) Classified AV materials such as photographs, slides, graphics according to the type of image, the area of the subject, and so on.(2) Analyzed key words selected from a screen or narration in each shot of a program and worked out a way to display the structure of a video program by the relationship of the key words.(3) Constructed a database system for assisting multimedia materials development. The main function of this system is to support selection of the appropriate video image by bibliographical data from the database, edition of the video image and production of a video disc as a master video for printing.(4) Produced three types of video discs assisted by the system.

国立多媒体教育研究所是为国立、公立和私立大学共同使用而设立的，目前正在研究和开发广播在高等教育中的实际应用。正在为空中大学、公立大学讲座和教师教育编制教育方案，并从世界各地收集这些方案供研究使用。同时，为了向日本高等教育机构的用户提供视听资源信息，将用于制作教育节目的图形、照片、幻灯片等视听资料存档并存储在数据库中。本课题的主要目的是构建一个数据库系统，以辅助高等教育多媒体资料的开发。主要研究成果如下。(1)根据图像类型、主题区域等对照片、幻灯片、图形等AV材料进行分类。(2)分析了在节目的每一个镜头中从画面或旁白中选取的关键词，并提出了一种利用关键词之间的关系来显示视频节目结构的方法。(3)建立了一个数据库系统来辅助多媒体素材的开发。该系统的主要功能是支持根据数据库中的书目数据选择适当的视频图像，编辑视频图像，并制作视频光盘作为打印用的主视频。(4)在该系统的帮助下制作了三种类型的视频光盘。
