Abstract
Abstract A multimedia database system effectively retrieves the contents in an optional storage position of an optional medium among a large amount of video and audio media. When a user puts an annotation to a specific range of a medium, the system registers an annotation object comprising the object ID of the target medium, specific range, and annotation information in a table. Next, when an annotation is put to a specific range of a medium once, the system automatically produces annotation objects for all media in the citation relation to it. The system manages the link relation between the citation destination and the citation source by a management table which is newly installed. The system retrieves the table and displays an annotation list coincident with the retrieval condition.
