DATA GENERATION METHOD, DATA REPRODUCTION METHOD, DATA GENERATION DEVICE AND DATA REPRODUCTION DEVICE

摘要

A data generation method for generating video data having a second luminance dynamic range wider than a first luminance dynamic range and having compatibility for reproduction by a first device that does not support video reproduction in the second luminance dynamic range but supports video reproduction in the first luminance dynamic range, comprises: a step (S101) for generating a video signal to be included in the video data using a second OETF; and a step (S102) for storing, in VUI within the video data, first transfer function information for specifying a first OETF that is referred to by a first device when the first device decodes the video data, and storing, in SEI within the video data, second transfer function information for specifying the second OETF that is referred to by a second device, which supports video reproduction in the second luminance dynamic range, when the second device decodes the video data.
