Claim 2:
3. An encoding method, performed by an encoding device, comprising:
encoding video data 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;
storing video usability information (VUI) including a first value indicating a first OETF; and
storing 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 a 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).
