Abstract

[Problema] Proporcionar: un dispositivo de decodificación que decodifica y reproduce, en un tiempo adecuado, información transmitida secuencialmente; un dispositivo de recepción; un dispositivo de transmisión; un sistema de transmisión/recepción; un método de decodificación; y un medio de almacenamiento que tiene un 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 tiempo de decodificación (22) determina el tiempo que la unidad de decodificación (21) decodifica los paquetes, con base en la información de ajuste que está incluida en el paquete y corresponde al ajuste de tiempo para hacer que el Horario Universal Coordinado se acerque al Horario Universal. Un paquete incluye información de intervalo de procesamiento que indica el intervalo de procesamiento para una unidad de acceso, que es un conjunto que incluye el paquete. La unidad de determinación del tiempo de decodificación (22) determina que los paquetes que constituyen cada unidad de acceso se decodificarán secuencialmente en un intervalo correspondiente al intervalo indicado por la información del intervalo de procesamiento, si la información de ajuste indica que se producirá un ajuste de tiempo.
