A method and apparatus for maximizing channel utilization by minimizing the number of null packets in an output stream such as an MPEG standard Transport Stream is provided by updating the output rate of a multiplexer such that its input buffers are constantly being serviced. The output rate is updated at the boundary of each serviced packet. In an alternative embodiment, the output rate is updated at the boundary of every L packets.
L'invention concerne un procédé et un appareil destinés à porter au maximum l'utilisation des canaux par la réduction du nombre de paquets nuls dans un flux de sortie tel que le flux de transport Transport Stream du standard MPEG, et ce grâce à la mise à jour du débit de sortie d'un multiplexeur, ladite mise à jour assurant le service constant des tampons d'entrée du multiplexeur. Le débit de sortie est mis à jour à la limite de chaque paquet desservi. Dans un autre mode de réalisation, le débit de sortie est mis à jour à la limite de tous les L paquets.
