    Abstract: In a reproduction method, a first video stream has a first dynamic range where a maximum value of a luminance dynamic range is more than 100 nits, and a display apparatus displays video in a second dynamic range narrower than the first dynamic range. The method includes: determining whether the first video stream is quantized based on a hybrid OETF; (i) when it is determined that the first video stream is quantized based on the hybrid OETF, reproducing the first video stream; and (ii) when it is determined that the first video stream is not quantized based on the hybrid OETF, converting a luminance dynamic range of the first video stream from the first dynamic range to the second dynamic range to obtain a second video stream, and reproducing the second video stream.

    Abstract: In a converting method for converting luminance of an input video in order to display the video on a display device, the luminance of the video is a first luminance value in a first luminance range where a maximum luminance value is defined as a first maximum luminance value that exceeds 100 nit. The method includes acquiring a first luminance signal indicating a first luminance value of the video, selecting a luminance converting process to be executed from among a plurality of luminance converting processes based on a reference luminance value corresponding to reference reflectance included in first meta data of the acquired first luminance signal, converting the first luminance value indicated by the acquired first luminance signal into a second luminance value in a second luminance range where a maximum luminance value is defined as a second maximum luminance value that is smaller than the first maximum luminance value and larger than 100 nit based on the selected luminance converting process.
