Abstract:
In a reproduction method, a video stream has a first dynamic range where a maximum value of a luminance dynamic range is more than a predetermined luminance value, and a display apparatus displays video in a second dynamic range narrower than the first dynamic range. The reproduction method displays video based on a first reproduction signal or a second reproduction signal. The first reproduction signal is obtained by: reproducing a first video stream quantized based on a hybrid OETF without performing luminance conversion; or reproducing the first video stream subjected to the luminance conversion. The second reproduction signal is obtained by performing the luminance conversion on a second video stream not quantized based on the hybrid OETF, and reproducing the second video stream subjected to the luminance conversion.
