Abstract

Se describe un sistema digital de difusión y un método de procesamiento de datos. El método de procesamiento de datos consiste en el agrupamiento de una pluralidad de paquetes de datos mejorados teniendo cada uno información contenida en estos, creando con ello un grupo de datos, creando e indicando una señal de identificación en una posición predeterminada de al menos un paquete de datos mejorado dentro del grupo de datos, la señal de identificación designa la inserción de una señal de sincronización de campo dentro de una trama de datos, el multiplexado del paquete de datos mejorado del grupo de datos y un paquete de datos principal, creando con ello una trama de datos, e insertando una señal de sincronización de campo dentro de la trama de datos con base en el paquete de datos mejorado que tiene la señal de identificación indicada en esta.
