Abstract

La présente invention concerne un procédé visant l'utilisation d'un signal de titres contenu dans des données par comparaison du signal de titre au signal de lecteur stocké dans un lecteur. Ce procédé comporte plusieurs opérations: disposer de données (102) pourvue d'un signal de titre; détection (104, 206), au niveau du lecteur, du signal de titre dans les données; comparaison (110, 214) du signal de titre au signal de lecteur stocké au niveau du lecteur; et accomplissement (114) d'une action en fonction de la comparaison. L'action sera, si le signal de titre concorde (112) avec le signal de lecteur, d'informer l'utilisateur du lecteur qu'il y a concordance et qu'il a gagné un prix. Selon une autre réalisation, le signal de titre est un sous-signal de filigrane codé dans les données numériques, auquel cas, le procédé comporte des opérations supplémentaires: extraction du signal de filigrane des données numériques; et décodage du sous-signal.
