Abstract

[Problema] Proporcionar: un dispositivo de decodificación que decodifica y reproduce, en un orden adecuado, información transmitida secuencialmente; un dispositivo de recepción; un sistema de transmisión/recepción; un método de decodificación; y un medio de almacenamiento que tiene el programa de decodificación almacenado en el mismo. [Solución] Una unidad de decodificación (21) que decodifica los paquetes enviados desde un dispositivo de transmisión (10). Una unidad de determinación de orden de decodificación (22) determina el orden de los paquetes que se codifican por la unidad de decodificación (21) decodifica los paquetes, con base en la información de ajuste que está incluida en el paquete y corresponde a un ajuste de tiempo para hacer que el Tiempo Universal Coordinado se acerque al Tiempo Universal. Los paquetes incluyen información del orden que indica el orden en el mismo flujo de datos IP. La unidad de determinación de orden de decodificación (22) determina, con base en la información del orden, el orden de los paquetes que se decodifican por medio de la unidad de decodificación (21), si la información de ajuste indica que se produce un ajuste de tiempo.
