Abstract

Systèmes et procédés pour l'évaluation des niveaux d'intérêt d'audience relative aux médias de radiodiffusion et pour la fourniture d'information supplémentaire sur la base des niveaux d'intérêt. Les procédés consistent à recevoir un signal AV de programme de radiodiffusion et un contenu supplémentaire qui comporte une information liée au programme et une étiquette identifiant le programme. Le contenu supplémentaire est combiné avec le signal AV pour la formation d'un signal augmenté de données qui est ensuite modulé avec un signal porteur donnant un signal de transmission pour diffusion aux récepteurs. Chaque récepteur comprend un décodeur d'extraction de contenu supplémentaire et un système d'évaluation des niveaux d'intérêt et de fourniture d'information supplémentaire sur la base des niveaux d'intérêt.
