Abstract
L'invention concerne l'amélioration de l'efficacité de traitement d'un processus utilisé pour coder des trames d'un flux binaire AC-3 amélioré en traitant chaque bloc audio une seule fois par trame. Les blocs audio de données codées sont décodées par ordre des blocs plutôt que par ordre des canaux. Des exemples de processus de décodage donnant lieu à des caractéristiques de codage de flux binaires améliorées telles qu'un traitement de transformation hybride adaptative et qu'une extension spectrale sont décrits.
