Claim of US Patent No. 10,560,999

1. A data generation device comprising:a generating circuit configured to generate video data according to a High Efficiency Video Coding (HEVC) standard; and
a storage to store:
video usability information (VUI) including a value selected from candidate values, the candidate values indicating respective opt-electrical transfer functions (OETFs); and
supplemental enhancement information (SEI) including a high dynamic range (HDR) parameter, wherein
the OETFs include at least one OETF supporting a standard dynamic range (SDR) for the video data, and
the HDR parameter is provided to widen a SDR to generate a HDR for the video data.
