Abrégé
(EN)
The invention discloses an equipment for detecting commercial automately comprising: video frame buffer, for storing first group of video frames and second group of video frames the television. received, which is apparent different with the first group of video frames in scene change rate; scene change detecting and calculating means, for reading the first group and second group of video frames stored in the video frame buffer, and set the last frame before the transition of first group to second group of video frame as key frame and calculating correlation of the video frame currently received and the key frame; informing signal generating means for generating informing signal when the correlation of the video frame currently received and the key frame is larger than or equal to predetermined threshold; controlling means, controlling the detecting and calculating means to perform reading and calculating action. And the invention also discloses a method for detecting commercial automately.
(FR)
L'invention porte sur un équipement de détection automatique de messages commerciaux comprenant: un tampon d'images vidéo recevant de la télévision un premier groupe d'images vidéo, et un deuxième groupe d'images vidéo différant du premier quant au rythme de changement des scènes; un moyen de détection et de calcul des changement de scènes enregistrés dans le tampon, sélectionnant la dernière image précédant la transition d'un premier groupe à un deuxième comme image clef, et calculant la corrélation entre l'image actuellement reçue et l'image clef; un moyen de production de signaux d'informations lorsque la susdite corrélation est supérieure ou égale à un seuil prédéterminé; et un moyen de commande du moyen de détection et de calcul en vue de la lecture et des calculs. L'invention porte également sur un procédé de détection automatique de messages commerciaux.
