CA 2394915

A re-multiplexer module for use in a packet processing system used in cable television headend devices generates two or more output streams from two or more MPEG input transport streams. The re-multiplexer module includes an input processing portion that receives a plurality of input data streams containing packet data, a plurality of packet buffers to store the packet data, an output processor that selectively multiplexes the data packets in the packet buffers, and a host processor that controls the operation of the input processing portion and the output processing portion.

L'invention concerne un module remultiplexeur, utile dans un système de traitement de paquets employé dans des dispositifs tête de bus de télévision câblée, et qui produit au moins deux flux de sortie, à partir d'au moins deux flux de transport d'entrée MPEG. Ce module comprend une portion de traitement d'entrée, laquelle reçoit plusieurs flux de données d'entrée contenant des données de paquets, plusieurs mémoires tampons de paquets, servant à stocker les données de paquets, un processeur de sortie, lequel multiplexe de manière sélective les paquets de données présents dans les mémoires tampons de paquets, ainsi qu'un processeur hôte, lequel commande le fonctionnement de la portion de traitement d'entrée et celui de la portion de traitement de sortie.
