Multimedia information systems are distinct from traditional information systems, particularly in terms of scheduling, media data, servers, and a number of other important issues. The relatively large size of multimedia data and the high bandwidth requirements for multimedia streams require new storage systems, buffering, delivery, and networking schemes. This work addresses many of these issues by focusing on the following: disk scheduling and storage hierarchy; configuration of multimedia servers and buffer management; delivery scheduling for multimedia streams; supporting user interactions; document modeling and temporal modeling of multimedia data; and integrated multimedia information system.
