Abstract

Las modalidades de la presente invención proporcionan un método y un aparato de procesamiento de señal. El método incluye: determinar una cantidad total de bits para ser asignados correspondientes a una trama actual; implementar una asignación de bits primaria en sub-bandas para ser procesadas; realizar una operación primaria de determinación de cantidad de unidades de información para cada sub-banda que ha sido sometida a la asignación de bits primaria, con el fin de obtener una cantidad de unidades de información correspondientes a cada sub-banda de las sub-bandas para ser procesadas y una cantidad total de los bits sobrantes; seleccionar sub-bandas para la asignación de bits secundaria de las sub-bandas para ser procesadas de acuerdo con al menos una característica de sub-banda de cada sub-banda de las sub-bandas para ser procesadas o la cantidad total de los bits sobrantes; implementar una asignación de bits secundaria en las sub-bandas para la asignación de bits secundaria; y realizar, de acuerdo con las cantidades de bits asignados de forma primaria y las cantidades de bits asignados de forma secundaria de las sub-bandas para la asignación de bits secundaria, una operación secundaria de determinación de cantidad de unidades de información para cada sub-banda de las sub-bandas para la asignación de bits secundaria, con el fin de volver a obtener una cantidad de unidades de información que corresponden a cada sub-banda de las sub-bandas para la asignación de bits secundaria. En las modalidades de la presente invención, una pérdida de bits se puede evitar, y la calidad de codificación y decodificación puede ser mejorada.
