Multimedia technologies are attracting more and more interest every day. Video-on-Demand is one of the buzzwords today and is now available for the public. Content providers such as publishers, broadcasting companies and audio/video production firms must be able to archive and index their productions for later retrieval. This is a formidable task and it is even more so when the material to be handled encompasses several media types and covers a time span of several years. In order for such a vast amount of data to be easily available, existing multimedia database design models, indexing and retrieval methodologies and delivery methods have to be improved and refined. In addition, video, image and audio data cannot be effectively managed with the exclusive use of older, keyword-based search techniques. My habilitation thesis collects new contributions to the research issues mentioned above. It contains ten research articles which focus on efficiency, in particular on the question of how the performance of multimedia database management systems, video servers and their front-ends, like the query optimizer for databases and the admission control for video servers, can be improved. My talk will focus on selected contributions of these articles. Especially, I will concentrate on the impact of meta-data and on the balance between the effort required and the efficiency enhancement that could be achieved in these systems.
Keywords: Multimedia Database Management Systems, Video Servers, Multimedia Content Indexing, Multimedia Query Optimization and Processing, Multimedia Content Adaptation, Parallel and Distributed Databases, MPEG-7, MPEG-4 and MPEG-21.
