Abstract

Procedimiento de codificación de audio y de la inclusión del citado audio codificado en un flujo de transporte digital, que comprende: recibir, en una entrada de codificador, de una pluralidad de señales de audio situadas en el mismo momento del tiempo; muestrear de la pluralidad de señales de audio situadas en el mismo momento del tiempo para formar una pluralidad de tramas alineadas de datos de audio de un tamaño predeterminado, en el cual tramas alineadas de datos de audio corresponden a un mismo periodo de tiempo; comprimir la pluralidad de tramas alineadas de datos de audio para crear tramas comprimidas; asignar marcas de tiempo idénticas por unidad de tiempo en las tramas comprimidas; e incorporar las tramas comprimidas en una pluralidad de flujos elementales del flujo de transporte digital.
