It provides interactive Video-On-Demand services in which the user has a cmplete control over the session proesentation. It allows the user to select and receive specific video information by retrieving the database. For improving the performance of video information retrieval and management, the video information, the video information is represented by hierarchiecal video metadata in XML u0006ormat. Video metadatabase stored the video information in this hierarchical structure and allows user to search the video shots at different semantic levels in the database. To browse the searched video, the use not only has full-function VCR capabilities as the traditional Video-On-Demanand, but also users over the Intenet, a membrership database is designed and managed in an E-Ccommeu0012ce environment, which allow the user to access the video database based ondifferent access levels.
