Abstract

Las modalidades se refieren a una unidad de procesamiento de audio que incluye un búfer, un desformateador de la carga útil de la secuencia de bits, y un subsistema de descodificación. El búfer almacena al menos un bloque de una secuencia de bits de audio codificada. El bloque incluye un elemento de relleno que comienza con un identificador seguido por los datos de relleno. Los datos de relleno incluyen al menos una bandera que identifica si el procesamiento de replicación de banda espectral mejorada (eSBR) va a realizarse sobre el contenido de audio del bloque. Se proporciona, además, un método correspondiente para descodificar una secuencia de bits de audio codificada.
