Abstract

Un proceso de mezclado inverso se realiza de manera apropiada y fácilmente en un lado de la recepción en un caso de la transmisión de los datos de las imágenes en movimiento mezcladas. La información que indican las tasas mezcladas y la información que indican las imágenes objetivo mezcladas se insertan dentro de los datos de la imagen codificados, asociados con las imágenes de las imágenes mezcladas en un caso de la transmisión de los datos de las imágenes en movimiento mezcladas. Además, la información que indican las tasas mezcladas y la información que indican las imágenes objetivo mezcladas en correspondencia con los datos de la imagen asociados con las imágenes de las imágenes mezcladas también se transmiten en un caso de la transmisión de los datos de las imágenes en movimiento mezcladas por una interfaz digital. Un proceso de mezcla inverso se puede realizar apropiadamente y fácilmente en un lado de la recepción sobre la base de la información que indican las tasas mezcladas y la información que indican las imágenes objetivo mezcladas.
