Abstract

En un método de reproducción que reproduce un flujo de video, el flujo de video tiene un primer intervalo dinámico en donde un valor máximo de un intervalo dinámico de luminancia es superior a 100 nits, un aparato de presentación visual presenta visualmente video en un segundo intervalo dinámico más estrecho que el primer intervalo dinámico, y se determina si el flujo de video se cuantifica con base en una OETF híbrida. Cuando se determina que el flujo de video se cuantifica con base en la OETF híbrida, se reproduce el flujo de video sin llevar a cabo conversión de luminancia en el flujo de video, la conversión de luminancia convirtiéndose del primer intervalo dinámico al segundo intervalo dinámico. Cuando se determina que la flujo de video no se cuantifica con base en la OETF híbrida, se lleva a cabo conversión de luminancia en el flujo de video y se reproduce el flujo de video.
