(EN) METHODS AND APPARATUS FOR DETECTING ON-SCREEN MEDIA SOURCES
(FR) PROCÉDÉ ET DISPOSITIF DE DÉTECTION DE SOURCES DE MÉDIA SUR ÉCRAN
Abrégé
(EN)
Methods and apparatus for detecting on-screen media sources are disclosed. An example method includes monitoring a region of interest of a video signal for a first image, comparing the first image to a stored image, and confirming the media device change when the stored image differs from the first image and is associated with a secondary criterion.
(FR)
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.
