Abstract

L'invention concerne un procédé et un système (30, 30', 100, 100', 100'', 100''') de remultiplexage de données supportant un programme vidéo (TS1-TS5, TS10-TS20), utilisant un système (122, 124, 129-4) à base de descripteurs pour programmer la sortie opportune de paquets de transport, utilisant un descripteur et une technique de mise en antémémoire (116, 122, 124, 114) de paquets de transport pour découpler la réception et la transmission synchronisées de paquets de transport de tout traitement asynchrone (160, 120, 130, S2, 402, S4, 404), utilisant des descripteurs pour crypter et décrypter des mots de commande (129-9), optimiser la largeur de bande des flux de transport en remplaçant les paquets de transport nuls par des données de paquet de transport, et utilisant une technique (180) permettant de verrouiller des générateurs (113) d'horloge de référence internes multiples.
