CA 2393029

An apparatus and method for decoding of encoded signals representing at least image information from a storage medium is claimed. A storage device (136) is configured to receive the storage medium. A decoder (144) is configured to receive the compressed encrypted encoded signals from the storage medium, and send the signals to a decryptor (320/324). The decryptor (320/324) is configured to decrypt the compressed encrypted encoded signals, and send the signals to a decompressor (320/324). The decompressor (320/324) is configured to receive the compressed encoded signals from the decryptor and to decompress the compressed encoded signals to enable display of the image.

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.
