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.
