Abstract

In the last decade, multimedia and, more particularly, video systems have benefited from a tremendous research interest. The main reason for this is the increasing ability computers now have for supporting video data, notably thanks to unceasing improvements in data compression formats (as MPEG-2 and MPEG-4), in network transfer rates and operating systems [1], and in disk storage capacity. Unsurprisingly, new applications have risen such as video on demand, video conferencing and home video editing which directly benefit from this evolution. Following this trend, research efforts ([2], [3]) have been made to extend DataBase Management Systems (DBMS) so that they support video data types not simply through Binary Large Objects (BLOB). Indeed, DBMS seem to be well-suited systems for tackling problems posed by the video, namely storage, modeling, querying and presentation. Video data types must be physically managed apart from other conventional data types in order to fulfill their performance requirements. Video modeling must take into account the hierarchical structure of a video (shots, scenes and sequences) and allow overlapping and disjoint segment clustering [4]. The video query language must (accordingly to MPEG-7 descriptions [5]) allow one to query video content using textual annotations or computed signatures (colour, shape, texture…) and deal with the dynamic (movements) of objects in the scenes as well as with semi-structural aspects of videos and, finally, must offer the possibility of creating new videos.
