Abstract

La presente invención transmite datos de imagen de velocidad normal de fotograma y alta velocidad de fotograma de manera satisfactoria. En los datos de imagen a alta velocidad de fotograma, se aplica un proceso de mezclado a una primera relación en unidades de dos fotos contiguas en tiempo y se obtienen datos de imagen de velocidad básica de fotograma, y también un proceso de mezclado a una segunda relación se aplica en unidades de dos fotos contiguas en tiempo y se obtienen datos de imagen extendidos que tienen una alta velocidad de fotograma. Un proceso de codificación se aplica en datos de imagen de velocidad de referencia de fotograma y se obtiene un flujo básico, y también se aplica un proceso de codificación en los datos de imagen de fotograma extendido que tienen la alta velocidad de fotograma y se obtiene un flujo extendido. Se transmite un contenedor de un formato prescrito que incluye el flujo básico y el flujo extendido.
