摘要：This paper describes the results of our efforts with regard to the design and implementation of an educational digital video library using MPEG-4 and the Synchronized Multimedia Integration Language (SMIL). The aim of our work is to integrate MPEG-4 encoding, full text indexing, high-resolution streaming, and SMIL, not only for delivering on-line digital video, but also for enabling content-based search for particular segments of a video clip stored in a repository of educational digital videos. One of the main purposes of the system is to provide new functionalities and solutions, which are not offered in conventional video libraries without online distribution facilities. Our system allows teachers, students and other users from 145 schools in our region, quick and easy access to a digital video repository via the Internet. They are able to store, search and retrieve catalogued streaming digital video content to be used for educational purposes.
