La plate-forme RAMSES pour un triple écran interactif : application à la génération automatique de télévision interactive

Abstract : The concept developed in this thesis is to propose an architecture model allowing automatic multimedia analysis and inserting pertinent interactive contents accordingly to multimedia content. Until nowadays, studies are mainly trying to provide tools and frameworks to generate a full description of the multimedia. It can be compared as trying to describe the world since the system must have huge description capabilities. Actually, it is not possible to represent the world through a tree of concepts and relationships due to time and computer limitations. Therefore, according to the amount of multimedia analyzers developed all over the world, this thesis proposes a platform able to host, combine and share existing multimedia analyzers. Furthermore, we only consider user’s requirements to select only required elements from multimedia platform to analyze the multimedia. In order to easily adapt the platform to the service requirements, we propose a modular architecture based on plug-in multimedia analyzers to generate the contextual description of the media. Besides, we provide an interactive scene generator to dynamically create related interactive scenes. We choose the MPEG-7 standard to implement the multimedia’s description and MPEG-4 BIFS standard to implement interactive scenes into multimedia. We also present experimental results on different kind of interactive services using video real time information extraction. The main implemented example of interactive services concerns an interactive mobile TV application related to parliament session. This application aims to provide additional information to users by inserting automatically interactive contents (complementary information, subject of the current session…) into original TV program. In addition, we demonstrate the capacity of the platform to adapt to multiple domain applications through a set of simple interactive services (goodies, games...).
