Abstract

Se describe un sistema y método de difusión digital para procesar datos. En la presente, un método para procesar datos en un sistema de transmisión incluye crear un grupo de datos que incluye una pluralidad de paquetes de datos de servicios móviles, reajustar una posición relativa de por lo menos un paquete de datos de servicios principales de una sección de datos de servicios principales, la sección de datos de servicios principales incluyendo una pluralidad de paquetes de datos de servicios principales y multiplexar los datos de servicios móviles del grupo de datos y lo datos de servicios principales de la sección de datos de servicios principales en unidades de ráfagas de impulsos. En la presente, una posición de un paquete de datos de audio entre los paquetes de datos de servicios principales de la sección de datos de servicios principales puede reajustarse. También, una posición de un paquete de datos de audio incluidos en la sección de datos de servicios principales puede reajustarse con base en una posición de multiplexión de la sección de datos de servicios principales.
