Abstract
Un flux de données comprend une pluralité d’identifiants et une séquence d’éléments binaires (Fnn). Un procédé de décodage de ce flux de données en une suite de données (V) de types respectifs prédéterminés comprend les étapes suivantes pour obtenir chaque donnée (V) de ladite suite : - détermination d’un contexte (C) sur la base d’un identifiant associé, parmi la pluralité d’identifiants, au type de la donnée concernée ; - décodage d’une partie de la séquence d’éléments binaires (Fnn) au moyen d’un décodeur entropique (23) recevant en entrée la séquence d’éléments binaires (Fnn) et paramétré dans le contexte déterminé (C). Un dispositif électronique de décodage (20) et un programme d’ordinateur associés sont également proposés. Figure pour l’abrégé : figure 5
