La CEI 61937-3:2007 décrit la méthode utilisée pour acheminer des flux de bits MIC non linéaire codés selon les formats AC-3 et AC-3 amélioré. Cette seconde édition de la CEI 61937-3 annule et remplace la première édition parue en 2003. La présente édition contient les importantes modifications techniques suivantes par rapport à la précédente édition. La définition de la salve de données audio nécessaire pour délivrer des flux de bits au format AC-3 amélioré a été ajoutée. La définition de la latence d'un décodeur AC-3 amélioré a été ajoutée. L'utilisation de salves de données de type Pause lorsque des flux de bits au format AC-3 amélioré sont délivrés a été ajoutée.
