Abstract

La presente tecnología se refiere a un aparato de recepción y un método de procesamiento de datos que permiten la sincronización del reloj de una manera más conveniente. El aparato de recepción recibe una señal de radiodifusión digital de un método de transmisión de IP que incluye información del tiempo y un flujo de contenidos. La información de tiempo incluye un campo de segundos y un campo de nanosegundos. El aparato de recepción a continuación, genera un reloj de procesamiento sincronizado con la información de tiempo sobre la base de la información de tiempo incluida en la señal de radiodifusión digital, y procesa el flujo incluido en la señal de difusión digital sobre la base del reloj de procesamiento. La presente tecnología se puede aplicar a, por ejemplo, receptores de televisión conforme al método de transmisión de IP.
