Abstract

Se proporciona un metodo para transmitir la informacion de control en un sistema de audio radiodifusion digital. El metodo comprende las etapas de transmitir una pluralidad de bitios de control en cada una de la pluralidad de armazones de control, en donde una primera secuencia de los bitios de control representa un modo de transmision, y una segunda secuencia de los bitios de control representa una palabra de sincronizacion de datos de control. La pluralidad de los bitios de control puede ademas incluir una tercera secuencia de bitios representativos de una palabra de sincronizacion de intercalador. Un metodo realizado en un receptor de radio para determinar el modo de transmision y sincronizacion para una senal de audio radiodifusion digital se proporciona tambien. El metodo comprende las etapas de recibir una pluralidad de armazones intercaladores que contiene informacion digital, en donde cada uno de los armazones del intercalador incluye una pluralidad de armazones de control. Los armazones de control incluyen una pluralidad de bitios de control, en donde una primera secuencia de los bitios de control representa un modo de transmision, una segunda secuencia de los bitios de control representa una palabra de sincronizacion de datos de control. La pluralidad de los bitios de control puede ademas incluir una tercera secuencia de bitios.
