Abstract

Sont décrits les procédés et les dispositifs permettant la détection des sources de média sur écran. Un procédé cité en exemple concerne la surveillance d'une région d'intérêt du signal vidéo d'une première image, la comparaison de cette première image avec une image stockée et la confirmation, lorsque l'image stockée diffère de la première image et est associée à un second critère, du changement de source de média.
