Abstract

Un decodificador de audio decodifica una corriente de bits de datos de audio codificado, en donde la corriente de bits de datos de audio codificado representa una secuencia de valores de muestras de audio y comprende una pluralidad de tramas, en donde cada trama incluye valores de muestras de audio codificado asociados. El decodificador de audio comprende un determinador configurado para determinar si una trama de los datos de audio codificado es una trama especial que comprende valores de muestras de audio codificado asociados con la trama especial, e información adicional, en donde la información adicional comprende valores de muestras de audio codificado de una cantidad de tramas que preceden la trama especial, en donde los valores de muestras de audio codificado de las tramas precedentes se codifican usando la misma configuración de códec que la trama especial, en donde la cantidad de tramas precedentes es suficiente para inicializar el decodificador para encontrarse en una posición para decodificar los valores de muestras de audio asociados con la trama especial si la trama especial es la primera trama, con el arranque del decodificador. El decodificador comprende un inicializador configurado para inicializar el decodificador, en donde la inicialización del decodificador comprende decodificar los valores de muestras de audio codificado incluidos en la información adicional antes de decodificar los valores de muestras de audio codificado asociados con la trama especial.
