Full title and description

IEC TR 63274:2021 — "Power consumption of high dynamic range television sets". This technical report introduces high dynamic range (HDR) video technology, reviews existing television-set power-consumption measurement methods, analyses market and measurement challenges for HDR TVs, and outlines a path forward for development of HDR TV power-measurement standards.

Abstract

IEC TR 63274:2021 provides a concise overview of HDR video formats and display behaviours that affect energy use; summarises current test methods used to measure TV power consumption; discusses how HDR content and peak-luminance handling complicate repeatable power measurements; examines market factors and measurement variability; and recommends directions for future standards work to achieve consistent, comparable HDR TV energy measurements.

Scope

The technical report's scope is to introduce HDR video concepts relevant to energy measurement, to describe and critique existing television power-measurement methods when applied to HDR content, to analyse the HDR TV market and device behaviours that drive power consumption, and to propose considerations and next steps for developing standardized, repeatable test methods for HDR television power measurement. It is intended as informative background and guidance rather than a prescriptive test standard.

Key topics and requirements

• Overview of HDR video technologies (formats, metadata, peak-luminance behaviours) and their impact on power draw.
• Summary of existing TV power-consumption measurement methods and metrics (typical-power, on-mode, standby, etc.).
• Analysis of measurement challenges introduced by HDR content: scene brightness variability, dynamic tone mapping, metadata-driven behaviour.
• Market analysis and examples illustrating variability between sets and measurement results.
• Recommendations and a roadmap for future standards development to achieve repeatable HDR TV power measurements (including candidate reference signals, measurement conditions, and reporting guidance).
• References to related normative documents and tests to be considered when developing HDR power-measurement methods.

Typical use and users

Intended users include standards committees and working groups (notably IEC TC 100/TA 19), TV and display manufacturers, test and certification laboratories, energy-labelling and regulatory authorities, product compliance engineers, and researchers studying display energy efficiency. The report is used as background material to inform development of normative test methods and to help manufacturers and labs anticipate measurement challenges introduced by HDR content.

Related standards

IEC TR 63274:2021 references and relates to existing standards and professional recommendations used in display and HDR ecosystems, for example IEC 62087 (methods for measuring audio, video and related equipment power consumption), ITU-R recommendations addressing colorimetry and HDR (ITU‑R BT.2100, BT.709, BT.1886, BT.2111), SMPTE documents on HDR metadata (SMPTE ST 2086, SMPTE ST 2036-1), and ARIB STD‑B67 (Hybrid Log-Gamma). These documents are identified in the report as relevant normative/background references when considering HDR power-measurement procedures.

FAQ

Q: What is this standard?

A: IEC TR 63274:2021 is a technical report from the International Electrotechnical Commission titled "Power consumption of high dynamic range television sets" that provides guidance, analysis and recommendations related to measuring HDR TV energy use.

Q: What does it cover?

A: It covers HDR video technology basics relevant to power, current TV power-measurement practices, marketplace and device behaviours that affect energy use, the measurement challenges posed by HDR content and workflows, and proposed directions for future standards to produce repeatable HDR TV power measurements.

Q: Who typically uses it?

A: Standards developers, display and TV manufacturers, test laboratories, compliance/energy-label authorities, and researchers use the report as background information to inform development and interpretation of HDR TV energy-measurement procedures.

Q: Is it current or superseded?

A: As published on 5 March 2021, IEC TR 63274:2021 is the current technical report edition (ed. 1.0). It is an informative technical report rather than a prescriptive, normative measurement standard; users should check for any subsequent normative standards or amendments that implement measurement procedures arising from this TR.

Q: Is it part of a series?

A: It is a Technical Report (TR) generated under IEC TC 100 (multimedia systems and equipment), specifically TA 19 (environmental and energy aspects for multimedia systems and equipment). The document complements other IEC and international recommendations on TV measurement and HDR, and is intended to inform later normative standards rather than function as a mandatory test method itself.

Q: What are the key keywords?

A: HDR, high dynamic range, power consumption, television, energy measurement, test methods, measurement challenges, IEC TR.
