User adaptable multimedia presentation for the World Wide Web

摘要

We propose a generic solution for user adaptation of synchronized multimedial presentations. We consider adaptation as a transformation problem: the user specifies a predicate that applied to a generic multimedia presentation yields a customized view of the presentation. We specify a means of expressing content descriptions and alternate content in generic multimedia presentations. User adaptation is based on content predicates that a player uses to select alternate content or elements that match content descriptions. Several examples show flexibility and expressing power of the proposed approach.
