Abstract

Un procédé de décodage d’une séquence d’éléments binaires comprend les étapes suivantes : - application, en entrée d’un réseau de neurones artificiels (29), de valeurs préalablement décodées (V) ; - en conséquence de ladite application, production d’un indice de contexte (C) en sortie du réseau de neurones artificiels (29) ; - obtention d’une nouvelle valeur décodée (V) par application d’une partie de la séquence d’éléments binaires (Fnn) à un décodeur entropique (30) paramétré dans le contexte identifié par l’indice de contexte (C) produit. Un dispositif électronique de décodage (20) et un programme d’ordinateur associés sont également proposés. Figure pour l’abrégé : figure 6
