This paper addresses content-based video retrieval with an emphasis on spatio-temporal modeling and querying of events. Our approach is based on a layered model that guides the process of translating raw video data into an efficient internal representation that captures video semantics. We also present a video query language and show that the proposed model facilitates execution of different types of queries. The main ideas have been implemented in order to achieve a prototype of a video database management system. Furthermore, results on real tennis video data are presented demonstrating the validity of the approach.
