HDR Research
Overview We are looking at what it would take to encode HDR-10 and Dolby Vision videos using an AVC/HEVC encoder. HDR-10 : 10-bit HDR, BT.2020, PQ transfer function, static metadata Dolby Vision : 12-bit HDR (10bit YUV + deltas defined in metadata = 12 bit), BT.2020, PQ transfer function, Dolby Vision dynamic metadata What is HDR-10? From this paper, we have gleaned the following: Essentially, HDR-10 is defined as the combination of the following container and coding characteristics: Color container/primaries: BT.2020 PQ Transfer function (OETF/EOTF): SMPTE ST 2084 Representation: Non Constant Luminance (NCL) YCbCr Sampling: 4:2:0 Bit Depth: 10 bits Metadata: SMPTE ST 2086, MaxFALL, MaxCLL, AVC/HEVC Supplemental enhancement information (SEI) Messages. Encoding using: HEVC Main 10 profile or AVC High 10. The AVC/HEVC specifications support all of these features as well as metadata (SEI) that can specify the mastering and brightness limitat...
