Abstract

Una unidad decodificadora (21) decodifica los paquetes transmitidos desde un transmisor (10). Una unidad de determinación del tiempo de decodificación (22) determina las cadencias de decodificación de los paquetes con el uso de la unidad decodificadora (21) sobre la base de la información de ajuste de acuerdo con el ajuste de los tiempos para hacer que el Tiempo Universal Coordinado esté cerca del Tiempo Universal, donde los tiempos se incluyen en los paquetes. Los paquetes incluyen procesar la información del intervalo que indica un intervalo de procesamiento de las unidades de acceso que son conjuntos que incluyen paquetes propios, y la unidad de determinación del tiempo de decodificación (22) determina decodificar en forma consecutiva los paquetes configurando las respectivas unidades de acceso en intervalos de acuerdo con el intervalo indicado por la información del intervalo de procesamiento cuando la información del ajuste indica que los tiempos están ajustados.
