Multimedia interactive services automation based on content indexing

On fixed or mobile television (TV), interactive services embedded in multimedia are key technologies as they forge links among the media, telecom, and services worlds. In a context where content evolves rapidly, the challenge is to be able to propose value-added services on live programs in real time. In this paper, we propose a solution that automates the generation of interactive TV applications, providing TV viewers with additional content in context with the original TV program. The proposed architecture is based on plug-in multimedia analyzers which generate a contextual description of the media and on an interactive scene generator to dynamically create related interactive scenes. Principles, architecture, implementation, and experiments are described; they are based on an application case related to interactive services added to a session of a French parliament TV program like "Les travaux de I'Assemblée Nationale" on the French television channel La Chai̊ne Parlementaire (LCP).
