Overview
IEC 62087-5:2015 - "Audio, video, and related equipment – Determination of power consumption – Part 5: Set‑top‑boxes (STB)" specifies standardized methods of measurement for the power consumption of set‑top boxes (STBs). This first edition isolates STB-specific measurement procedures from the multipart IEC 62087 series and cancels/replaces Clause 8 of IEC 62087:2011. The standard applies to mains‑connected STBs and defines operating modes, measuring conditions and procedures that represent normal use.
Key Topics and Technical Requirements
- Operating modes and functions: Defines the relevant STB modes (e.g., On mode, Partial On modes) and additional/special functions that affect power draw.
- Auto power down: Specifies how to treat auto power down features that transition an STB into a lower‑power Partial On mode after a preset time.
- Measuring conditions: Details required conditions for power measurement including stabilization, environmental conditions, and test setup to ensure repeatable results.
- Input signals and terminals: Covers RF test signals, broadband/IP inputs and common STB input terminals (terrestrial, cable, satellite, digital inputs) to reflect real‑world loading during tests.
- Measurement procedure: Specifies how to perform power measurements (measurement points, stabilization time, and setup configurations) for consistent and comparable results.
- Annex A (informative): Provides background on STB technology, buffering/time‑shift functions, and multi‑tuner scenarios that influence energy use.
- Scope limitations: Applicable only to equipment that can be connected to the mains; measurement conditions represent normal use and may differ from safety test setups.
Keywords naturally embedded: IEC 62087-5:2015, set‑top boxes, STB, power consumption, measurement methods, auto power down, measuring conditions, On mode, Partial On mode.
Practical Applications & Who Uses This Standard
- STB manufacturers and designers: for designing energy‑efficient products and validating power performance during development.
- Test houses and conformity labs: for reproducible, internationally accepted power consumption measurements used in reports and certification.
- Regulators and energy programs: to establish benchmark test methods for energy labeling or minimum energy performance requirements.
- Service providers and system integrators: to assess operational energy costs across deployments (multi‑room, IP‑TV or hybrid networks).
- Product managers and sustainability teams: to quantify and reduce device energy consumption in real‑use scenarios.
