Abstract

Dispositif d'analyse et de certification de fichiers multimédia pour la mesure d'audience basée sur le watermarking ou fingerprinting. Il est caractérisé en ce qu'il comporte un moyen de rognage des fichiers (1) selon une résolution (R), un moyen de subdivision (2) des fichiers, une distribution (10) des morceaux obtenus sur différents moyens de détection de mesure d'audience (3) fonctionnant en parallèle (P) par exemple dans un cloud permettant la création d'une courbe de répartition de probabilités de détection de référence selon la durée d'observation (27) pour une combinaison de technologie et type de détecteur donnés (information non existante en l'état technique antérieur), une analyse par échantillonnage des morceaux de fichiers à certifier, et enfin un moyen de comparaison (5) des résultats des fichiers analysés avec ceux de la courbe de référence (27). Il est destiné à fiabiliser et accélérer l'analyse de grandes quantités de fichiers chez les éditeurs de contenus.
