Full title and description

Information technology — MPEG systems technologies — Part 10: Carriage of timed metadata metrics of media in ISO base media file format. Defines a standardized storage and carriage format for timed metadata (quality, power/energy and related metrics, coordinates/ROI, etc.) associated with media tracks in files based on the ISO base media file format (ISO/IEC 14496-12), enabling uses such as dynamic adaptive streaming and power-aware media consumption.

Abstract

This standard specifies how to store and carry time-aligned metadata as dedicated metadata tracks in ISO base media files and how to associate those metadata tracks with media tracks. It defines sample entry types and configuration boxes for quality and energy (green) metrics, a set of metric codes and value encodings, conventions for coordinates and regions of interest, and interoperability rules for embedding these timed metrics so downstream players, encoders/transcoders and analysis tools can consume them consistently.

Scope

Specifies a storage and carriage format for timed metadata carried in files conforming to the ISO base media file format (ISO/IEC 14496-12). The timed metadata covered includes, but is not limited to, measurable quality metrics (e.g., PSNR, SSIM variants), energy/power-related metrics and indicators, and coordinate/ROI data. The standard defines how metadata tracks are declared, formatted, and linked to media tracks and provides rules to ensure interoperability between content producers, packagers and players. It supports applications such as dynamic adaptive streaming, content-guided transcoding, ROI-based processing and power-aware playback strategies.

Key topics and requirements

• Timed metadata storage model: metadata carried as dedicated tracks within the ISO base media file and associated to media tracks via track references.
• Sample entry and configuration structures: defines sample entry types (example: a quality-metrics sample entry) and configuration boxes to declare metric codes, field sizes and packing rules.
• Defined metric types and encodings: standard metric codes for objective quality measurements (PSNR, SSIM/MS-SSIM, VQM, PEVQ, MOS proxies, frame significance, etc.) and guidance on numeric encodings and sample padding.
• Green/energy metadata support: fields for power/energy related indicators (decoder power, display power reduction hints) to enable energy-aware workflows and players.
• Coordinates and ROI carriage: support for 2D coordinate data and encoded regions of interest for use in ROI-aware encoding and delivery.
• Interoperability rules: mandatory use of registered codes and conventions (codec parameterization conventions, sample alignment and naming) to ensure consistent interpretation across toolchains.
• Extensibility and amendments: mechanisms for adding metric codes or profile extensions; amendments exist to add support for content-guided transcoding, immersive spatial relationships and display attenuation maps.

Typical use and users

Adopted by media system architects, streaming and CDN engineers, packager and player developers, codec vendors, post-production and quality-assurance teams, and researchers working on objective video quality, power-efficient playback and adaptive streaming. Typical uses include embedding QoE/QoS metrics in packaged files, driving bitrate/adaptation decisions with timed metrics, enabling ROI-based workflows and supplying energy-related metadata to power-aware clients.

Related standards

Directly relates to ISO/IEC 14496-12 (ISO base media file format). It is part of the ISO/IEC 23001 series (MPEG systems technologies) and interoperates with other MPEG delivery and file format parts. Implementation frequently references codec parameterization conventions (e.g., RFC 6381 style parameters) and other MPEG system specifications and amendments that extend timed-metadata use cases (for content-guided transcoding, immersive media relationships and display attenuation maps).

FAQ

Q: What is this standard?

A: ISO/IEC 23001-10:2020 is the MPEG systems part that defines a standardized format for carrying timed metadata metrics (quality, energy, coordinates/ROI, etc.) inside ISO base media files so that metadata can be associated with media tracks and consumed by players and processing tools.

Q: What does it cover?

A: It covers the file-level structures, sample entry types and configuration boxes for metric tracks, a set of metric codes and encodings, conventions for linking metadata tracks to media tracks, and interoperability rules for consistent use of timed metrics in packaged media.

Q: Who typically uses it?

A: Content providers, packagers, streaming platform engineers, player and codec implementers, QA teams and researchers who need to include or consume time-aligned quality, energy or ROI metadata alongside audio/video streams.

Q: Is it current or superseded?

A: The document is the second edition published in April 2020 and is published/active. It has received amendments to extend functionality (for example, amendments adding support for content‑guided transcoding, immersive spatial relationships, and display attenuation maps). Users should check for any later amendments or revisions when implementing.

Q: Is it part of a series?

A: Yes. It is Part 10 of the ISO/IEC 23001 series (MPEG systems technologies) and is designed to work with ISO/IEC 14496-12 (ISO base media file format) and other related MPEG/ISO system specifications.
