ITU-R HD standards

Following are the ITU standards that govern digital high-definition TV. Rec. 709 originally specified resolutions of 1,125 and 1,250 lines but added 1080 lines in 2000 to conform to digital TV (DTV). For standard definition (SD) component digital standards, see Rec. 601.

In 2013, HDMI 2.0 added support for Rec. 2020 resolutions (see HDMI).

In 2016, Rec. 2100 added PQ and HLG high dynamic range (HDR) encoding (see PQ and HDR).

The upgraded Cinema RAW Development software features the addition of 3D-LUT for converting from Cinema Gamut/DCI-P3+ to such highly versatile color space standards as ITU-R BT.709 (Rec.
With an IPS panel and 10-bit processing circuit, the BT-3DL2250 offers six colour settings--SMPTE, EBU, ITU-R BT.709, Adobe 2.2, Adobe 1.8 and D-Cinema--for superior colour range and a 3Dl look-up table (LUT) for calibration.
Given any set of ITU-R BT.709 RGB triplets whose chromaticity is within the intersection of the color gamuts of the BT.709 primaries and these color samples, a reasonably accurate SRD can be reconstructed for any AX using only the mean and first three principal components of the dataset for an assumed illuminant (such as CIE D65).
Instead, we only need reasonable approximations for common architectural materials when given their CIE xyY or ITU-R BT.709 color space values.
Given that most lighting simulation programs enable the user to choose material colors in the ITU-R BT.709 color space with red, green, and blue values ranging from 0.0 to 1.0, it makes sense to divide the [RGB.sub.709] color cube into ten equally-spaced steps in each dimension and perform the following:
What the charts do show however is more important: the ITU-R BT.709 color space used by lighting simulations for predicting photometric quantities is acceptably accurate for most architectural environments.
The firmware upgrade will enable users of the Canon DP-V3010 to display and confirm video content captured and recorded in not only the currently supported DCI-P3 (SMPTE PR 431-2), ITU-R BT.709 (Rec.
Sony added that its ChromaTRU technologies and 10-bit panel driver work effectively to emulate colours and gammas of CRT monitors and to support broadcast standards (SMPTE-C, EBU and ITU-R BT.709).
