Abstract

Se proporciono un método para transmitir informacion de control en una disposicion de emision de audio digital. El método comprende las etapas detransmitir una pluralidad de bits de control en cada uno de una pluralidad de cuadros de control, en el q ue una primera secuencia de los bits de controlrepresenta un modo de transmision, y una segunda secuencia de los bits de control una palabra de sincronizacion de datos de control. La pluralidad de bits depalabra puede además incluir una tercera secue ncia de bits representativos de una palabra de sincronizacion intercaladora. También se proporciona un método quese efectua en un receptor de radio para determinar el modo de transmision y la sincronizacion para una senal de emision de audio digital. El método comprendelas etapas de recibir una pluralidad de cuadros intercaladores que contienen informacion digital, en el que cada uno de los cuadros intercaladores incluyen unapluralidad de cuadros de control. Los cuadros de control incluyen una p luralidad de bits de control, en los que una primera secuencia de los bits de controlrepresentan un modo de transmision, una segunda secuencia de los bits de control, una palabra de sincronizacion de datos de control. La pluralidad de bits decontrol puede incluir además una tercera secuencia de bits representativos de una palabra de sincronizacion intercaladora. La primera secuencia de bits decontrol es procesada para determinar un modo de transmision; la segunda secuencia de bits de control es procesada para determinar la sincronizacion de datos decontrol; y la tercera secuencia de bits de control es procesada para determinar límites del intercalador. También se revelan transmisores y receptores de radiofrecuencia que utilizan los métodos arriba senalados.
