Abstract

Des échantillons de sous-bandes de données auxiliaires représentant un signal de données auxiliaires (315) sont transportés dans un signal audio numérique comprimé codé en sous-bande sans décompression des données. Un flux préexistant de données mises en paquets (305) est transmis à une entrée d'un codeur (310). Des échantillons audio de sous-bande (406) sont extraits depuis le flux de données mises en paquets et normalisés (408). Les données à transporter modulent les sous-bandes porteuses de données (SPD0, SPD1, ---SPDN-1) comprenant un signal d'étalement de spectre à pseudo-bruit (PN), dont chaque sous-bande possède une largeur de bande correspondant à celles du signal audio numérique. La séquence porteuse de données modulées est combinée aux échantillons de sous-bande audio (SS1, SS2---SSN-1), afin de créer un signal combiné (452), multiplexé ensuite (460) en un flux préexistant de paquets de données (407). Dans le décodeur (368), le signal combiné est démodulé afin de récupérer le signal de données auxiliaires (672). Ce signal récupéré est porté de façon sensiblement inaudible dans le signal audio et est soumis à une mise en forme spectrale en fonction du signal audio, de manière à amplifier le masquage d'erreurs.
