Abstract

L'invention porte sur une méthode d'attribution de bits de remplissage comportant les étapes suivantes: division de la séquence initiale de bits d'information pour identifier le nombre de blocs de codage nécessaires à la division sur la base des longueurs des blocs de codage supporté par le codage des canaux; sélection d'au moins deux blocs de codage présentant chacun une longueur correspondant à une valeur discrète voisine de celle des blocs de codage supporté par le codage des canaux, en fonction du nombre identifié de blocs de codage et de la longueur des blocs de codage supportés; réduction du nombre de bits de remplissage à attribuer aux blocs de codage sélectionnés; attribution des bits de remplissage à tous les blocs de codage, dont les longueurs sont en moyenne minimales, parmi les blocs de codage; et attribution de tous les bits de remplissage à chacun des blocs de codage pour égaliser sensiblement le rapport de codage de chaque paquet de codage en fonction dudit rapport.
