Abstract

Se divulga un sistema de difusión digital que incluye un sistema de recepción de difusión y un método de procesamiento de datos. En el sistema de recepción de difusión que recibe señales difundidas, el sistema de recepción de difusión incluye una unidad de decodificación de parámetros de transmisión, un detector de secuencia conocida, y un controlador de ráfaga. La unidad de decodificación de parámetros de transmisión detecta información en una ráfaga de una señal recibida a partir de datos difundidos que tienen datos de servicios principales y datos de servicios móviles multiplexados ahí dentro de un campo de la señal recibida y produce la información detectada en la ráfaga. El detector de secuencia conocida recibe información de ráfaga a partir de la unidad de decodificación de parámetros de transmisión y utiliza la información de ráfaga recibida y la información de posición de datos conocida incluida en los datos recibidos para producir información de control de ráfaga. El controlador de ráfaga utiliza la información de control de ráfaga para controlar la alimentación en energía del sistema de recepción de difusión.
