international programme exchange

ii Rec. ITU-R BT.2100-1
Foreword
The role of the Radiocommunication Sector is to ensure the rational, equitable, efficient and economical use of the
radio-frequency spectrum by all radiocommunication services, including satellite services, and carry out studies without
limit of frequency range on the basis of which Recommendations are adopted.
The regulatory and policy functions of the Radiocommunication Sector are performed by World and Regional
Radiocommunication Conferences and Radiocommunication Assemblies supported by Study Groups.
Policy on Intellectual Property Right (IPR)
ITU-R policy on IPR is described in the Common Patent Policy for ITU-T/ITU-R/ISO/IEC referenced in Annex 1 of
Resolution ITU-R 1. Forms to be used for the submission of patent statements and licensing declarations by patent
holders are available from http://www.itu.int/ITU-R/go/patents/en where the Guidelines for Implementation of the
Common Patent Policy for ITU-T/ITU-R/ISO/IEC and the ITU-R patent information database can also be found.

Image parameter values for high dynamic range television for use in
production and international programme exchange
(2016-2017)
Scope
High Dynamic Range Television (HDR-TV) provides viewers with an enhanced visual experience by
providing images that have been produced to look correct on brighter displays, that provide much brighter
highlights, and that provide improved detail in dark areas. This Recommendation specifies HDR-TV image
parameters for use in production and international programme exchange using the Perceptual Quantization
(PQ) and Hybrid Log-Gamma (HLG) methods.
Keywords
High dynamic range, HDR, television, HDR-TV, image system parameters, television production,
international programme exchange, wide colour gamut, perceptual quantization, PQ, hybrid
log-gamma, HLG
The ITU Radiocommunication Assembly,
considering
a) that digital television image formats for HDTV and UHDTV have been specified by the
ITU-R in Recommendations ITU-R BT.709 and ITU-R BT.2020;
b) that these television image formats have been limited in the image dynamic range they can
provide due to their reliance on legacy cathode ray tube (CRT) characteristics that limit image
brightness and detail in dark areas;
c) that modern displays are capable of reproducing images at a higher luminance, greater
contrast ratio and wider colour gamut than is conventionally employed in programme production;
d) that viewers expect future television viewing to provide improved characteristics compared
with the current HDTV and UHDTV in terms of a more realistic sensation, greater transparency to
the real world and more accurate visual information;
e) that high dynamic range television (HDR-TV) has been shown to increase viewer
enjoyment of television pictures;
f) that HDR-TV provides a “step-change” improvement in viewer experience by means of
substantially increased brightness and detail in highlights and diffuse reflecting objects, while
providing greater detail in dark areas;
g) that the combination of extended dynamic range and extended colour gamut give HDR-TV
a substantially larger colour volume;
h) that the HDR-TV image formats should have, where appropriate, a degree of compatibility
with existing workflows and infrastructure;

Revisions to parameter values within this document should be compared to those in the previously
published version of this Recommendation.
2 Rec. ITU-R BT.2100-1
i) that a reference viewing environment including display parameters should be defined for
HDR-TV image formats,
further considering
that due to rapid developments in HDR technology the ITU may wish to consider early updates and
improvements to this Recommendation,
recognizing
that Report ITU-R BT.2390 contains much information on two methods to achieve HDR-TV,
recommends
that for programme production and international exchange of HDR-TV, the perceptual quantization
(PQ) or Hybrid Log-Gamma (HLG) specifications described in this Recommendation should be
used.
NOTE – The PQ specification achieves a very wide range of brightness levels for a given bit depth
using a non-linear transfer function that is finely tuned to match the human visual system. The HLG
specification offers a degree of compatibility with legacy displays by more closely matching the
previously established television transfer curves. Report ITU-R BT.2390 provides additional
information on PQ and HLG, conversion between them, and compatibility with previous systems.

NOTE 1a – Container is used to define the horizontal and vertical constraints of the image format.
NOTE 1b – Productions should use the highest resolution image format that is practical. It is recognized that
in many cases high resolution productions will be down-sampled to lower resolution formats for
distribution. It is known that producing in a higher resolution format, and then electronically down-sampling
for distribution, yields superior quality than producing at the resolution used for distribution.
