Abstract
El presente documento se refiere a un método de codificación en capas de una representación de sonido comprimido de un sonido o campo de sonido. La representación de sonido comprimido comprende una representación de sonido comprimido básica que comprende una pluralidad de componentes, información lateral básica para la decodificación de la representación de sonido comprimido básica a una representación de sonido reconstruida básica del sonido o campo de sonido, e información lateral de mejoramiento que incluye parámetros para mejorar la representación de sonido reconstruida básica. El método comprende la subdivisión de la pluralidad de componentes en una pluralidad de grupos de componentes, y la asignación de cada uno de la pluralidad de grupos a un respectivo de una pluralidad de capas jerárquicas, el número de grupos correspondientes al número de capas, y la pluralidad de capas incluye una capa base y una o más capas de mejoramiento jerárquicas, la adición de información lateral básica a la capa base, y la determinación de una pluralidad de porciones de información lateral de mejoramiento a partir de la información lateral de mejoramiento, y la asignación de cada una de la pluralidad de porciones de información lateral de mejoramiento a uno respectivo de la pluralidad de capas, donde cada porción de información lateral de mejoramiento incluye parámetros para mejorar una representación de sonido reconstruida que se obtiene de datos incluidos en la respectiva capa y cualquier capa más baja que la respectiva capa. El documento adicionalmente se refiere a un método de decodificación de una representación de sonido comprimido de un sonido o campo de sonido, donde la representación de sonido comprimido es codificada en una pluralidad de capas jerárquicas que incluyen una capa base y una o más capas de mejoramiento jerárquicas, al igual que a un codificador y un decodificador para la codificación en capas de una representación de sonido comprimido.
