HDR10

The most common open HDR standard.

HDR10 Media Profile is an open HDR standard. It is the most widespread of the HDR formats. HDR10 was announced on 27 August 2015 by the Consumer Technology Association.

PQ10 refers to a format that is the same as HDR10 without the metadata.

Technical details

HDR10 is defined as:

  • EOTF: SMPTE ST 2084 (PQ)
  • Bit depth: 10 bit
  • Color primaries: Rec.2020 (identical to Rec.2100 primaries)
  • Static metadata: SMPTE ST 2086 (Mastering Display Color Volume), MaxFALL, MaxCLL
  • Color sub-sampling: 4:2:0 (for compressed video sources)
  • PQ10 refers to an HDR format that uses PQ, 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 backward compatible with SDR displays.

On HDR10 displays that have lower color volume than the HDR10 content (for example lower peak brightness capability), the HDR10 metadata gives information to help adjust the content. However the metadata are static (remain the same for the entire video) and do 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+ (that do provide dynamic metadata allowing to preserve the creative intents on each display and on a scene by scene or frame by frame basis) and also HLG (that do provide some degree of backward compatibility with SDR).

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.
