Abstract

Le procédé de mise à niveau technique d'un récepteur de données diffusées par paquets, depuis un émetteur, consiste à décaler la position d'un champ d'adresse jusqu'à une nouvelle position (22) et, dans le récepteur, on charge, par une disquette, un bloc de données comportant, à la fois, des données de programmation de circuits programmables de réception des paquets spécifiant à ceux-ci la nouvelle position du champ d'adresse (22), et des données de programmation d'un processeur, pour certifier et mémoriser la bonne réception des données (23).
