Abstract

We introduce a constraint-driven methodology for the automated assembly, organization and playout of presentations from multimedia databases.We use inclusion and exclusion constraints for extracting a semantically coherent set of multimedia segments. Presentationorganization constraints are utilized for organizing the multimedia segments into apresentation, which in turn helps decide the playout order of the extractedmultimedia segments. The playout order of the segments is represented in a presentationgraph. If the specified set of organization constraints are not sufficient toconstruct a unique presentation graph, we propose two techniques so that a unique graph isconstructible. We also propose two playout algorithms, one for the generation, start andtermination of playout agents, the other for dynamic control of playout management on organized presentations.The characteristics of these algorithms are expressed in terms of presentation playout parameters.
