Abstract

Le dispositif comprend plusieurs modules de paquétisation (C1, C2, ..., Cn) alimentant des mémoirés de paquets (PM1, PM2, ..., PMm) à partir de flux numériques d'entrée (IS1, IS2, ..., ISn), et des moyens de multiplexage (14). Chaque paquet présent dans une mémoire de paquets est associé à des paramètres d'élection écrits par son module de paquétisation dans une mémoire de paramètres associée (ZM1, ZM2, ..., ZMm). Les moyens de multiplexage comprennent des moyens de traitement reliés aux mémoires de paramètres par un bus de paramètres (12) pour sélectionner les mémoires de paquets d'où extraire les paquets du multiplex en analysant les paramètres d'élection respectivement associés aux premiers paquets en attente dans chacune des mémoires de paquets, et des moyens de transfert reliés aux mémoires de paquets par un bus de paquets (10) et commandés par les moyens de traitement pour extraire successivement les paquets du multiplex depuis les mémoires de paquets sélectionnées.
