Design and Management of Metadata-based Multimedia Systems using Active Networks

Project Details


In general, the purpose of this project is to perform fundamental research that will result in a new platform for the development of metadata-based multimedia applications by using active networks. A format for the use of metadata in this context will be developed. Moreover, it will be investigated to which extend object-oriented methodologies can be applied for the development of multimedia appli¬cations that rely on active networks. Therefore, interfaces will be defined, being descriptions of the functionality of the considered multimedia objects traversing the network. The temporal synchroniza¬tion between the actual multimedia data and the corresponding metadata will be investigated as well. For this purpose a data structure allowing for the efficient processing and management of the metadata will be developed. Concerning the research topics dealing with active networking, it is aimed to prove the inherent advantages of using active networks for multimedia applications. We will also investigate efficient encoding techniques for multimedia data, and more specifically video content, and examine how the coding can maximally support the underlying network.
As was stated above, the global approach (i.e., the combined optimization of the (meta)data (de)coding and the management of the used network) is a key concept within this project. This is the main reason why this project will be performed within the research groups of the promoters Jan Cornelis, Steven Dewitte en Peter Schelkens (Vrije Universiteit Brussel, Department of Electronics and Information Processing, expertise: multimedia compression), Rik Van de Walle (Ghent University, Department of Electronics and Information Systems; expertise: multimedia systems and applications), and Piet Demeester, Bart Dhoedt and Mario Pickavet (Ghent University, Department of Information Technology; expertise: broadband networks). In order to be able to achieve the aforementioned goals several research aspects will be addressed.
