Abstract

Un método de transmisión de conformidad con un aspecto de la presente invención es un método de transmisión de un dispositivo de reproducción que transmite señales de video a un dispositivo de presentación visual, e incluye: cuando una versión de un protocolo de transmisión sea una primera versión, transmitir primeros metadatos al dispositivo de presentación visual sin transmitir segundos metadatos al dispositivo de presentación visual, mientras el protocolo de transmisión conecta el dispositivo de reproducción y el dispositivo de presentación visual, los primeros metadatos son información que se usa comúnmente para una pluralidad de imágenes incluidas en una unidad de reproducción continua de la señal de video y se refieren a un intervalo de luminancia de la señal de video, y los segundos metadatos son información que se usa comúnmente para una unidad subdividida en comparación con la unidad de reproducción continua de la señal de video, y se refieren al intervalo de luminancia de la señal de video; y cuando la versión del protocolo de transmisión sea una segunda versión, transmitir los primeros metadatos y los segundos metadatos al dispositivo de presentación visual.
