Title (EN) APPARATUS AND METHOD OF ENCODING AND DECODING AUDIO SIGNAL
(FR) APPAREIL ET PROCEDE DE CODAGE ET DE DECODAGE D'UN SIGNAL AUDIO
Abstract:
(EN) A method and apparatus of encoding and decoding an audio file are disclosed. A pair of channels of an audio data frame included in an audio file independently or synchronously is switched based on whether a correlation between the channels exists. The channels are switched hierarchically at one or more block switching levels. Then, first block switching information is generated. The first block switching information indicates whether the channels are switched independently or synchronously and how the channels are switched at the block switching levels, respectively.
(FR) La présente invention concerne un procédé et un appareil de codage et de décodage d'un fichier audio. Une paire de voies d'une trame de données audio inclue dans un fichier audio de manière synchrone ou indépendante est commutée lorsqu'il existe une corrélation entre les voies. Les voies sont commutées de manière hiérarchique à un ou plusieurs niveaux de commutation des blocs. Des informations de commutation de premier bloc sont ensuite générées. Les informations de commutation de premier bloc indiquent si les voies sont commutées indépendamment ou de manière synchrone et la manière dont les voies sont respectivement commutées aux niveaux de commutation des blocs.
