Dynamic metadata high dynamic range impacts on TV power consumption
IEC TR 63449:2023 presents a study of the impact of high dynamic range (HDR) technologies with "dynamic metadata" on TV luminance and power consumption. It compares the power consumption of content with dynamic metadata to the same content without dynamic metadata. Non-dynamic "static metadata" HDR technologies such as HDR10 and non-metadata HDR such as HLG, were previously studied in IEC TR 63274:2021.
This document also reviews the current HDR TV market and analyses existing HDR TV power measurement methods and considerations for any changes to those power measurement standards.
While this document studies the results of content that include Dolby Vision® and HDR10+ dynamic metadata, any comparison of these two technologies is outside of the scope of this document.

INTRODUCTION
HDR technologies affect the entire video ecosystem from production and processing, through
to distribution and presentation. HDR-capable television sets typically have higher peak
luminance and better low-luminance capabilities than non-HDR TVs and can take advantage of
HDR video signals which typically represent scenes with much higher luminance and more
detailed low-luminance levels than was possible in traditional analogue and digital non-HDR
video systems.
As the luminance range of an HDR signal might not match the luminance range capabilities of
the display device, the signal must be adjusted before being displayed. This luminance
adjustment is called tone-mapping and is implemented as a processing step in the TV. The tone
mapping process can be improved with metadata, which describes the properties of the content
to be displayed.
Dynamic metadata based HDR tone-mapping approaches and behaviours are seeing an ever-
increasing application in consumer televisions; however, representative standardized test
content for measurement of the power consumption impact of those technologies on televisions
is not available. To prepare objective test materials (video clips), a study of power and
luminance behaviour was conducted, the results of which are described in Clauses 5 and 6.
This document assesses the impact of dynamic HDR on TV luminance and power consumption
using two technologies currently in deployment.
A small sample of TVs that supported the two technologies were studied using "representative"
content prepared by PT100-24 members. Test results show that dynamic metadata HDR
content, delivered to a dynamic metadata capable TV, can provide pictures with even greater
dynamic range (higher peak luminance and more detailed luminance levels with wider colour
gamut) than static HDR at the same or lower TV power consumption versus static HDR or SDR
content delivered to that same TV.
DYNAMIC METADATA HIGH DYNAMIC RANGE
IMPACTS ON TV POWER CONSUMPTION
1 Scope
This document presents a study of the impact of high dynamic range (HDR) technologies with
"dynamic metadata" on TV luminance and power consumption. It compares the power
consumption of content with dynamic metadata to the same content without dynamic metadata.
Non-dynamic "static metadata" HDR technologies such as HDR10 and non-metadata HDR such
as HLG, were previously studied in IEC TR 63274:2021.
This document also reviews the current HDR TV market and analyses existing HDR TV power
measurement methods and considerations for any changes to those power measurement
standards. ®
While this document studies the results of content that include Dolby Vision and HDR10+
dynamic metadata, any comparison of these two technologies is outside of the scope of this
document.

4 Dynamic metadata high dynamic range video
4.1 Introduction to dynamic metadata HDR video
4.1.1 Overview
Older video creation, broadcast and television receiver technologies, collectively called
"Standard Dynamic Range" (SDR) for the purposes of this technical report, do not provide
images that accurately represent the light distribution and detail of real-world scenes .
Significant technological progress in video content creation, distribution and displays now
permit consumers to receive and display almost life-like programming by adding several key
aspects missing from older SDR technologies. Specifically:
– higher pixel counts (up from 1 920 × 1 080 image pixels Full HD to UHD with 3 840 × 2 160
or more image pixels);
– higher image frame rates (up from a maximum of 60 Hz to 120 Hz or more);
– greater dynamic range (image peak brightness up to 10 000 cd/m );
– wider colour gamut embracing more of the CIE 1931 (x, y) chromaticity space vs the
common limit to ITU-R BT.709 colour primaries with SDR images.
Roughly a decade ago, HDR technologies entered the market. Since then, many consumers
have been enjoying video content offering much of the key aspects described above in a form
this report refers to as "static metadata HDR". Static metadata in this report's context means
that for a given "static metadata" HDR video programme, the content author provides ancillary
data along with the programme. This data describes several characteristics of the video which

‘Real-world’ refers to physically accurate representations of light distribution as well as spatial and temporal detail
that are captured e.g., by a camera but also includes artistically created or adjusted content.
for example represent the peak luminance, minimum luminance, and colour gamut of the entire
programme. The receiver can only make a single set of tone-mapping adjustments based on
this information, which then remains constant or 'static' throughout the display of the full
programme. A previously published technical report, IEC TR 63274:2021, discussed static
metadata HDR technologies and their impact on television energy use.
In addition to static metadata, another metadata approach is available in the market which this
report refers to as "dynamic metadata HDR". Dynamic metadata in this report's context refers
to metadata provided by the content author on a frame-by-frame or scene-by-scene basis which
allows video production and television receivers to make adjustments frame-by-frame when
processing and displaying such programmes. This has several benefits to the content author's
creative needs and provides useful information allowing a receiver to display the content
author's intended rendering of that programme more accurately.
Subclauses 4.1.2 and 4.1.3 detail the main properties of the two "dynamic metadata HDR" ®
formats Dolby Vision and HDR10+ considered by this Technical Report.
NOTE There are other dynamic HDR technologies such as SL-HDR2 (ETSI TS 103 433-2), SL-HDR3
(ETSI TS 103 433-3) and HDR Vivid which were not evaluated as content and televisions employing those
technologies were not globally available. ®
4.1.2 Dolby Vision ®
Dolby Vision is a commercial imaging format created by Dolby Laboratories, Inc. This format
enables a modular ecosystem that provides an extensive set of implementations and methods
to facilitate imaging features such as HDR. These features are implemented in a wide range of
soft and hardware products used with image capture, processing, and display, both in the
consumer and professional market segments. This includes many of today's TVs. ®
On a foundational level, the Dolby Vision image signal uses the PQ EOTF (SMPTE ST 2084)
with a quantization granularity of up to 12 bits, but the HLG EOTF is also supported through
compatibility profiles. To support accurate and perceptually meaningful transformations such ®
as mapping the current content scene to a TV's capabilities, individual Dolby Vision enabled
devices can rely on comprehensive image-related metadata. This metadata offers several
distinct parameters supporting how the image signal is encoded, decoded, mapped, rendered,
and ultimate appears within input, processing, and output scenarios. ®
One metadata type of Dolby Vision is frame accurate dynamic metadata, derived from
statistical analysis of the content imagery. This facilitates the preservation of the creative intent,
independent of the target display capabilities (see SMPTE ST 2094-10 for more details). In
addition to computational analysis, manual creative input can be assigned to the dynamic ®
metadata through Dolby Vision Trim Passes, which give content creators the opportunity to
adjust the colour volume mapping to their exact requirements and preference. ®
To guarantee the accurate interpretation of the aforementioned metadata, Dolby Vision offers ®
a dedicated colour volume-mapping engine that is implemented in Dolby Vision enabled
devices. This mapping engine can in many cases also facilitate real-time adjustments to guide
the HDR tone mapping, e.g., taking into account the display reflectivity and surrounding
illumination in the viewing environment.
4.1.3 HDR10+
HDR10+ is a royalty-free HDR format with a certification, logo and licensing program by
HDR10+ Technologies, LLC, a joint venture between Panasonic Corporation and Samsung
Electronics.
– 14 – IEC TR 63449:2023 © IEC 2023
It uses dynamic metadata as opposed to static (i.e. single value set established for a specific
item of content) metadata used by standard HDR10. The use of dynamic metadata means that
HDR10+ can change each frame's parameters, therefore frames are treated separately by their
own set of brightness, colour and contrast values. Additionally, HDR10+ can signal a maximum
luminance of 10 000 cd/m . It is an open format meaning it can be modified and deployed by
organisations other than HDR10+ LLC stakeholders. The certification and logo licencing
programme is royalty-free with some associated annual administrative fees as described on the
LLC website.
HDR10+ technology includes:
• EOTF (Electro-Optical Function): SMPTE ST 2084 (PQ)
• Chroma subsampling: 4:2:0 (compression format)
• Resolution: agnostic (2K/4K/8K, etc.)
• Bit representation: 10-bit or more (up to 16-bit)
• Colour space: ITU-R BT.2020
• Pixel representation: up to 10 000 cd/m
• Metadata (Required): Mastering Display Colour Volume Metadata (SMPTE ST
2086)
• Metadata (optional): MaxCLL, MaxFALL
• HDR10+ is applicable for HEVC, AV1, VVC and VP9 compatibility via WebM as well as any
codec that supports ITU-T T.35 metadata.
NOTE 1 VVC (Versatile Video Coding), also known as H.266, ISO/IEC 23090-3, and MPEG-I Part 3, is a licence-
based video compression standard developed by ISO/IEC JTC 1/SC 29 (MPEG).
NOTE 2 VP9 is an open and royalty-free video coding format developed by Google and stated as the WebM Project's

4.3 Consumer availability of dynamic metadata HDR video technologies in TVs
While difficult to get an accurate tally of exactly how many dynamic metadata capable HDR TVs
are in consumer's homes worldwide, the CTA's 23rd Annual U.S. Ownership and Market
Potential Study (July 2021) provides an indication of consumer adoption of HDR TVs in the U.S.
It should be noted that CTA's report does not cover the full 2021 calendar year and therefore
the numbers provided here are estimates. In addition, CTA's study does not differentiate
between static metadata HDR TVs and dynamic metadata HDR capable TVs. For reference,
the relevant numbers from CTA's U.S. study are shown below:
• Total U.S. population = 328 million [U.S. Census Bureau December 2020]
• Total U.S. occupied housing units = 120 million [U.S. Census Bureau December 2020]
• Total U.S. TV households = 109 million [per CTA over 91 % of homes own a TV]
• Ownership of 4K UHD TVs (2021 est.) = 57 million units [per CTA over 50 % of TV
households]
• Ownership of HDR TVs (2021 estimate) = 34 million units [per CTA over 30 % of TV
households]
The North American Broadcasters Association (NABA) published its study and HDR
Recommendation Overview (August 2021) which noted virtually all Smart TVs support both
HDR10 and HLG. The study also reported that current HDR content production consists of
HDR10 which is widely used for feature films and scripted TV content, while HLG is widely used
for sports and other live production.
The NABA study also noted that U.S. broadcasters, cable operators and streaming providers ®
use HDR10 and "optional" dynamic metadata (Dolby Vision and HDR10+) content. However,
the study did not compare the different HDR technologies in terms of percentage of programmes
broadcast, but did note that video streaming, where HDR content is more prevalent, is
increasing in U.S. viewing habits, and among streaming capable homes, accounts for as much
as 25 % of total TV usage.
The NABA report concludes with a recommendation: "That systems based on an underlying
PQ-based HDR transfer function (SMPTE ST 2084) with optional static (SMPTE ST 2086)
and/or dynamic metadata (SMPTE ST 2094) be used for ATSC 3.0 program emission in North
America."

In Germany, the Deutsche TV-Plattform, an association of private and public organisations
involved in digital media, provides a database of UHD devices supporting HDR10, HLG, Dolby
Vision® and HDR10+. German data for 2021/Q1 – Q3 UHD TV sales (ZVEI, Deutsche TV
Platform, GfK) showed 98 % of UHD TVs support at least one HDR format and 77 % of UHD
TVs support at least one dynamic HDR format (either Dolby Vision® or HDR10+).
5 Dynamic metadata HDR TV power consumption research
5.1 Overview
As both the content and the consumer TV landscape is shifting towards dynamic HDR use,
investigations in this document are focused on:
1) understanding how TV power and luminance responds to dynamic metadata content
available today as this content is largely limited to movies and series available through
9 10
streaming services like Amazon Prime / Amazon Instant Video , NETFLIX and on Blu-
ray™ discs;
2) characterizing the impact of test media developed by 2050 Partners and colour graded by
their professional feature film digital mastering subcontractor, Company 3 , to represent
dynamic metadata video after the expected transition of broadcast content to include
dynamic metadata.
Because many uncertainties remain in how dynamic metadata will progress in terms of
technology, compatibility, content provider, distribution network practices, and market adoption,
this report and its data represent a snapshot in time the project team used to increase its
understanding of the ecosystem. Since the dynamic metadata HDR ecosystem is still evolving,
the report's data might not be useful in answering questions policymakers might have related
to this topic.
Subclause 5.2 describes the dynamic metadata test media developed by the project team to
represent future broadcast content with dynamic metadata for the purpose of laboratory tests
using current dynamic metadata capable televisions. Subclause 5.3 explains the methods,
findings, and conclusions of that research, which focused on understanding the power and
luminance impacts of both dynamic metadata test media and real-world content.
5.2 Dynamic metadata test media
As the basis for dynamic metadata test content, the project team chose to use the same raw
video content captured by CLASP for the purpose of developing HDR test materials and on
which the IEC HDR10 test media, proposed for IEC 62087-2:2023 was based. This content was
created by a team of experts on professional equipment. Company 3 judged this content as
high quality and suitable for this project's intended purpose.

The following instructions were provided to Company 3 to create the dynamic metadata test
media:
• Use the provisionally approved IEC 62087-2:2023 static metadata HDR10 test media as
shown in Table 1 below.
• Apply the same edits, tone mapping and workflow Company 3 typically does for Dolby
Vision® and HDR10+ clients to the above IEC 62087-2:2023 HDR10 static metadata test
media to yield new Dolby Vision® and HDR10+ dynamic test media that meet the
requirements in Table 1 below. Annex A provides information on the test material workflows.
• Add a 10-second countdown timer over ITU-R BT.2111 colour bars to identify start of test
sequence.
