Abstract

L'invention concerne des procédés et un appareil permettant de détecter un événement de changement de chaîne de télévision. Un desdits procédés consiste à essayer de détecter un numéro de chaîne dans une première zone d'intérêt sur un instantané d'écran de télévision. Si le numéro de chaîne est détecté, le procédé consiste ensuite à essayer de détecter une bannière dans cet instantané. Si une bannière est détectée, le procédé consiste alors à enregistrer l'événement de changement de chaîne.
