Document Type and Number:
Japanese Patent JP6583740
Kind Code:
B2
Abstract:
In a reproduction method that reproduces a video stream, the video stream has a first dynamic range where a maximum value of a luminance dynamic range is more than 100 nits, a display apparatus displays video in a second dynamic range narrower than the first dynamic range, and it is determined whether the video stream is quantized based on a hybrid OETF. When it is determined that the video stream is quantized based on the hybrid OETF, the video stream is reproduced without performing luminance conversion on the video stream, the luminance conversion converting from the first dynamic range to the second dynamic range. When it is determined that the video stream is not quantized based on the hybrid OETF, the luminance conversion is performed on the video stream and the video stream is reproduced.
