Title (EN) METHOD OF ENCODING AND DECODING AN AUDIO SIGNAL
(FR) PROCEDE DE CODAGE ET DE DECODAGE D'UN SIGNAL AUDIO
Abstract: front page image
(EN)An apparatus for encoding and decoding an audio signal and method thereof are disclosed, by which compatibility with a player of a general mono or stereo audio signal can be provided in coding an audio signal and by which spatial information for a multi-channel audio signal can be stored or transmitted without a presence of an auxiliary data area. The present invention includes extracting side information embedded in non-recognizable component of audio signal components and decoding the audio signal using the extracted side information.
(FR)La présente invention se rapporte à un appareil permettant de coder et de décoder un signal audio ainsi qu'à un procédé associé, selon lequel il est possible d'obtenir une compatibilité avec un lecteur conçu pour lire un signal audio mono ou stéréo général lors du codage d'un signal audio et selon lequel des informations spatiales associées à un signal audio multicanaux peuvent être stockées ou transmises sans l'existence d'une zone de données auxiliaire. La présente invention consiste à extraire des informations auxiliaires incluses dans une composante non identifiable des composants du signal audio et à décoder le signal audio au moyen des informations auxiliaires extraites.
