IEC 62087-2:2023

Overview

IEC 62087-2:2023 (Audio, video, and related equipment - Determination of power consumption - Part 2: Signals and media) defines the audio‑visual test signals and media used to measure power consumption of televisions, computer monitors and related equipment. This second edition (2023) is a technical revision of the 2015 edition and standardizes signal types, signal generation equipment, interfaces and accuracy requirements. All test signals are provided as downloadable media files from an IEC online repository, replacing previous DVD/Blu‑ray distribution.

Key topics and technical requirements

• Scope of signals: Static video, dynamic broadcast‑content, internet‑content video signals, and associated audio signals for power consumption testing.
• HDR and UHD support: New HDR and UHD video test signals added in this edition to reflect modern display technologies.
• Peak luminance ratio: Signals and procedures to determine peak luminance ratio - a metric sometimes used in TV power measurements.
• Dynamic box & outline signals: Dynamic test patterns now replace static box/outline signals to better represent real content behavior.
• Media provision: Test signals are provided as downloadable files from the IEC 62087‑2 online repository (https://www.iec.ch/tc100/supportingdocuments).
• Signal generation & interfaces: Specification of acceptable signal sources and interfaces including USB, HDMI®, DisplayPort, component/S‑Video/composite analogue, terrestrial/cable/satellite and network interfaces.
• Equipment and accuracy: Requirements for signal‑generation equipment, interfaces and accuracy of video/audio signal levels to ensure repeatable, comparable power measurements.
• Normative and informative annexes: Annex A lists downloadable test media; Annex B/C describe the video signals and peak luminance patterns.

Practical applications and users

IEC 62087-2:2023 is intended for:

• Manufacturer test and design teams performing power consumption characterization and validating display power modes.
• Independent test laboratories and certification bodies conducting regulatory compliance, energy labeling and eco‑design testing.
• Regulators and standards authorities establishing measurement protocols for televisions and monitors.
• R&D and QA groups evaluating the impact of content type (SDR, HDR, UHD, streaming) on power draw and luminance behavior.
  Using standardized signals ensures reproducible, comparable power measurements across products, test houses and markets.
