From video information retrieval to hypervideo management
Résumé
The digital revolution that has somehow taken place with the World-Wide Web took advantage of the availability and interoperability of tools for visualisation and manipulation of text-based data, as well as the satisfying pertinence of search engines results that makes them usable by non-expert users. If we are to undergo such a revolution in the audiovisual domain, a number of issues mainly related to the temporal nature of audiovisual documents have to be resolved. In this article, we expose our view of the current state of Audiovisual Information Systems, and suggest that they should be considered as video information management systems rather than video retrieval systems, in order to foster new uses of video information. We define the notion of hypervideo that can be used as an analysis framework for this issue. We then describe our implementation of hypervideos in the Advene framework, which is aimed at DVD material annotation and analysis. We eventually discuss how the notion of hypervideo puts video information retrieval in a somewhat different light.
