HDR10


HDR10 Media Profile, more commonly known as HDR10, is an open high-dynamic-range video standard announced on 27 August 2015, by the Consumer Electronics Association. It is the most widespread HDR format.
HDR10 is not backward compatible with SDR. It includes HDR static metadata but not dynamic metadata.
PQ10 refers to an HDR10 format which does not include any metadata.

Technical details

HDR10 is defined as:
  • EOTF: SMPTE ST 2084
  • Bit depth: 10 bit
  • Color primaries: ITU-R BT.2020
  • Static metadata: SMPTE ST 2086, MaxFALL, and MaxCLL
  • Color sub-sampling: 4:2:0
PQ10 refers to an HDR format that uses Perceptual quantization, 10-bit and Rec. 2100 color primaries without having any metadata.
HDR10 is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.
HDR10 is not backwards compatible with SDR displays.
On HDR10 displays that have lower color volume than the HDR10 content, the HDR10 metadata gives information to help adjust the content. However, the metadata is static and does not tell how the content should be adjusted. Thus, the decision is up to the display and the creative intents might not be preserved.
Competing formats to HDR10 are Dolby Vision and HDR10+, and also HLG.

Adoption

HDR10 is supported by a wide variety of companies, which include monitor and TV manufacturers such as Dell, LG, Samsung, Sharp, VU, Sony, and Vizio, as well as Sony Interactive Entertainment, Microsoft and Apple which support HDR10 on their PlayStation 4, Xbox One video game console and Apple TV platforms, respectively.
