Abstract

L'invention concerne un dispositif de visualisation de séquences vidéo comprenant une unité d'affichage vidéo (110), qui affiche une séquence d'images à une vitesse déterminée en fonction d'un signal de commande, et un analyseur de séquence (100), qui analyse la séquence et génère le signal de commande en fonction du résultat de l'analyse. L'invention concerne également un procédé de marquage par filigranes, qui consiste à modifier d'une manière prédéterminée la longueur d'une séquence que l'on a l'intention de marquer par filigranes.
