Abstract
Though there has been extensive work on multimedia databases in the last few years, there is no prevailing notion of a multimedia
view, nor there are techniques to create, manage, and maintain such views. In this paper, we present a formal definition of
a multimedia view definition (MVD). Materializing an MVD corresponds to assembling and delivering an interactive multimedia
presentation in accordance with the specification. We develop a probabilistic model of interactive multimedia presentations
where the probabilities reflect the likelihood of certain user interactions. Based on this probabilistic model, we develop
a prefetching algorithm that anticipate how users will interact with the presentation. These prefetch algorithms allow efficient
delivery of these multimedia presentations in accordance with the underlying specification. We have built a prototype system
that incorporates these algorithms. We report on the results of experiments conducted on top of this implementation.
