Rec. 2020 defines a bit depth of either 10 bits per sample or 12 bits per sample. [2] 10 bits per sample Rec. 2020 uses video levels where the black level is defined as code 64 and the nominal peak is defined as code 940. Codes 0–3 and 1,020–1,023 are used for the timing reference.
Rec. 2100 is a technical recommendation by ITU-R for production and distribution of HDR content using 1080p or UHD resolution, 10-bit or 12-bit color, HLG or PQ transfer functions, full or limited range, the Rec. 2020 wide color gamut and YC B C R or IC T C P as color space.
Coding-independent code points (CICP) is a way to signal the properties of a video or audio stream. [1] [2] It can describe the color profile of videos (and still images) in a simpler way than the use of ICC profiles. [3] It is defined in both ITU-T H.273 and ISO/IEC 23091-2. [1]
It has a peak luminance of at least 1,000 cd/m2 [9] (higher than the 100 cd/m2 limit of SDR and color spaces such as Rec. 709 and Rec. 2020). [10] [11] [12] It uses a non-gamma transfer function (PQ or HLG) and system colorimetry (chromaticity of color primaries and white point) identical to Rec. 2020 system colorimetry. [9]
Rec. 601, Rec. 709 and Rec. 2020: The ITU-R recommendations BT.601, BT.709 and BT.2020 describe the reference OETF of respectively SD-TV, [3] HD-TV [2] and UHD-TV. [4] They are identical OETF based on a gamma curve and used for SDR-TV .
DCI-P3 covers 86.9% of Pointer's gamut, [5] while in comparison, Rec. 709/sRGB only covers 69.4%. While DCI-P3 was developed by the Digital Cinema Initiatives (DCI) organization, many of the relevant technical standards are published by the Society of Motion Picture and Television Engineers (SMPTE) such as SMPTE EG 432-1 and SMPTE RP 431-2 .

a photographic exposure of an 18% grey card would map to (,,) RGB code value. ACES2065-1 code values often exceed for ordinary scenes, and a very high range of speculars and highlights can be maintained in the encoding. The internal processing and storage of ACES2065-1 code values must be in floating-point arithmetics with at least 16 bits per ...
Imagination Technologies said that 10-bit per sample video would allow for larger color spaces and is required for the Rec. 2020 color space that will be used by UHDTV. They also said the Rec. 2020 color space would drive the widespread adoption of 10-bit-per-sample video. [161] [165]
