Abstract
Coming across with the emerging Knowledge Society, the enriched video is nowadays a hot research topic, from both academic and industrial perspectives. The principle consists in associating to the video stream some metadata of various types (textual, audio, video, executable codes, ...). This new content is to be further exploited in a large variety of applications, like interactive DTV, games, e-learning, and data mining, for instance. This paper brings into evidence the potentiality of the watermarking techniques for such an application. By inserting the enrichment data into the very video to be enriched, three main advantages are ensured. First, no additional complexity is required from the terminal and the representation format point of view. Secondly, no backward compatibility issue is encountered, thus allowing a unique system to accommodate services from several generations. Finally, the network adaptation constraints are alleviated. The discussion is structured on both theoretical aspects (the accurate evaluation of the watermarking capacity in several reallife scenarios) as well as on applications developed under the framework of the R&D contracts conducted at the ARTEMIS Department.
