Abstract
Cette invention concerne un dispositif et une technique permettant de décoder à partir d'un support de stockage des signaux codés représentant au moins une information image. Un dispositif de stockage (136) est configuré pour recevoir un support de stockage. Un décodeur (144) est conçu pour recevoir, à partir du support de stockage, des signaux codés cryptés comprimés et de les transmettre à un décrypteur (320/324). Ce décrypteur est conçu pour décrypter les signaux codés cryptés compressés et pour les transmettre à un décompresseur (320/324). Ce décompresseur est conçu pour recevoir du décrypteur les signaux codés compressés et pour les décompresser en vue de l'affichage de l'image.
