A Database-Centric Approach to Enabling EndtoEnd QoS for Multimedia Repositories
The paper discusses the design and prototype implementation of a QoS aware multimedia database system. Recent research in multimedia databases has devoted little attention to the aspect of the integration of QoS support at the user level. One common scenario which the authors are concerned with connects a user through a visual interface to a multitude of media object stores. The user demands satisfiability of a set of quality parameter bounds specified at query time or before. The user is not aware of detailed low-level QoS parameters but rather specifies high-level, qualitative attributes on the media query.
