Abstract

Un método para difusión digital de audio comprende los pasos de recibir una pluralidad de bits de datos que deben ser transmitidos, dar a la pluralidad de bits de datos el formato de una pluralidad de unidades de datos de protocolo, insertar bits de cabecera en ubicaciones espaciadas dentro de las unidades de datos de protocolo, y usar las unidades de datos de protocolo a fin de modular una pluralidad de portadoras para producir una senal de salida. Los bits de cabecera individuales pueden ser colocados en posición en ubicaciones espaciadas uniformemente en las unidades de datos de protocolo. Un primer bits de los bits de cabecera puede ser desplazado desde un extremo de la unidad de datos de protocolo. Se proveerá también un método para recibir la senal digital de difusión de audio y transmisores y receptores que operará de acuerdo con los métodos.
