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 Pocket Cinema Camera works with industry standard 17 and 33 point 3D LUT files, or customers can work with the built in LUTs such as Extended Video, Film to Video, Film to Rec.2020 and more.
The phone also features a Creator Mode that is said to cover 100 percent of the DCI-P3 colour gamut, along with the BT.2020 (REC.2020) colour space.
Required functional scope: The mixers offered shall have at least the performance and the functional scope of the devices currently used by arte geie (see article 1); Designed for hd-sdi 1080i / 25 and 50p with sdi interfaces as well as upgradeability to uhd-1 phase 2 via ip interfaces (smpte st2110 or higher) on the basis of the existing equipment; Hdr and wcg support (rec.2020); The imagemixers meet the following technical characteristics: - controllability through automation systems; - integration of the necessary protocols (rs, Ip, Vdcp, Etc.) for the control of third-party devices (audio, Video, Graphics); - possibility of controlling the system watchout (dataton) via rs or ip interface; - compatibility with the lawo vsm platform used by arte (tally and labeltransfer).
HDR TVs will also require WCG standards to achieve optimal visual quality, and at this point the most likely candidate for this is the BT.2020 (often referred to Rec.2020) introduced in 2012.
The Rec.2020 gamut is the required colour space for Dolby Vision, while HDR10 can do with DCI-P3.
