Claim 0:
1. A decoding method, performed by a decoding device, comprising:
receiving video data generated according to a video coding standard and a second opto-electrical transfer function (OETF), an intensity of light within a second range being input into the second OETF, the video coding standard including at least an Advanced Video Coding standard and a High Efficiency Video Coding standard;
decoding the video data;
receiving video usability information (VUI) including a first value indicating a first OETF; and
receiving supplemental enhancement information (SEI) including a second value indicating the second OETF, wherein
the VUI and the SEI are supported by the video coding standard,
the first OETF supports a first range of an input intensity of light and the second range is wider than the first range,
the first value is to be referred to by the decoding device that does not support the second OETF,
the first range and the second range correspond to a first luminance range and a second luminance range, respectively,
the second luminance range is wider than the first luminance range,
the first range is a standard dynamic range (SDR), and
the second range is a high dynamic range (HDR).
