Abstract
Una sincronización de reloj y una sincronización de presentación se logran adecuadamente en el caso donde la transmisión se lleva a cabo mediante la transportación, sobre una señal de radiodifusión, un paquete de medios de transmisión obtenido mediante la fragmentación de medios de transmisión tales como vídeo y audio. Un reloj de 27 MHz sincronizada con la información en tiempo adquirida desde un servidor de información de tiempo Se genera. El tiempo de información incluyendo la información de la frecuencia del reloj de 27 MHz y sincronizada con la información de tiempo adquirida desde el servidor de información de tiempo se genera. Un medio de transmisión se codifica. El medio de transmisión codificado está fragmentado en una unidad predeterminada, y un paquete de medios de transmisión incluyendo cada fragmento se genera. Un flujo que incluye, sobre una base de división de tiempo, el paquete de medios de transmisión, un paquete que incluye la información de tiempo, y un paquete que tiene una señal de control se transporta sobre una onda de radiodifusión y se transmite.
