Techniques for determining an output rate for a bit stream, the output rate being determined by applying information read from the bit stream to available bandwidths. The techniques are employed to construct a statistical multiplexer (80) that multiplexes varying bit-rate bit streams. Minimum and maximum output rates for each bit stream are determined such that neither a queue for the bit stream in the multiplexer nor the bit stream's decoder will underflow or overflow. The multiplexer first allocates each bit stream its minimum bandwidth and then allocates any remaining bandwidth to the bit streams in proportion to the difference between the minimum and maximum output rates for the bit streams, with no bit stream receiving more than its maximum output rate. If there is not enough bandwidth to give every bit stream its minimum rate, glue frames may be inserted, or low priority channels dropped.

L'invention concerne des procédés permettant de déterminer un débit de sortie d'un train binaire, le débit de sortie étant déterminé par l'application d'informations lues à partir du train binaire aux largeurs de bande disponibles. Ces procédés sont utilisés pour construire un multiplexeur statistique (80) qui multiplexe des trains binaires à débit binaire variable. On détermine des seuils maximaux et minimaux de débits de sortie pour chaque train binaire de telle sorte que ni une file d'attente du train binaire dans le multiplexeur ni le décodeur du train binaire ne soient sous-passés ou dépassés. Le multiplexeur alloue d'abord sa largeur de bande minimale à chaque train binaire pour ensuite allouer la largeur de bande restante aux trains binaires par rapport à la différence entre les débits de sortie minimaux et maximaux des trains binaires, aucun train binaire ne recevant un seuil maximal de débit de sortie plus élevé que le sien. Si la largeur de bande est insuffisante pour assurer à chaque train binaire son débit minimal, il est possible d'insérer des trames de collage ou de supprimer des canaux à basse priorité.
