Abstract

La présente invention concerne un système de distribution de données et de vidéo qui peut tenir compte du changement dynamique de la structure de son audience. A la réception d'informations provenant de cette audience, on peut modifier automatiquement le contenu de la diffusion. On peut, par exemple, annoter des informations diffusées et on peut utiliser des informations relatives à la programmation sélectionnée par les téléspectateurs ou à des données annexes pour évaluer la structure de l'audience en cours. Ces informations peuvent être fournies sous forme d'informations en retour au système de diffusion de façon à modifier la nature des informations diffusées.
