Abstract

Se revelan un sistema de transmision digital y un método de procesamiento de datos. En un aspecto de la presente, provee un método de procesamiento de datos que incluye recibir una senal de transmision en la cual se multiplexan datos de servicio principal y datos de servicio movil, demodular la senal de transmision recibida, enviar la informacion de tiempo de demodulacion de una posicion específica de un cuadro de senal de transmision, y adquirir la informacion de tiempo de referencia contenida en el cuadro de datos de servicio movil, ajustar la informacion de tiempo de referencia con un reloj de tiempo del sistema a un momento especifico en base a la informacion de tiempo de demodulacion; y decodificar los datos de servicio movil de acuerdo al reloj de tiempo del sistema.
