Overview
ISO/IEC 19566-5:2023/Amd 1:2025 is an amendment to the international standard for information technologies focusing on JPEG systems. This amendment specifically enhances Part 5, which covers the JPEG Universal Metadata Box Format (JUMBF). The update introduces key features such as JUMBF box compression and the use of standalone JUMBF files. These additions aim to improve metadata management for JPEG files by allowing efficient compression of metadata boxes and providing flexibility for metadata storage outside of image files.
The amendment is published by ISO and IEC, reflecting their ongoing collaboration in developing standards for multimedia coding and metadata interoperability.
Key Topics
JUMBF Box Compression: The amendment defines how JUMBF payload boxes can be compressed to optimize metadata size. It introduces the Brob Box (‘brob’), which uses Brotli compression according to IETF RFC 7932. This compression reduces the overhead of metadata in JPEG files, making usage more storage and bandwidth efficient.
Standalone JUMBF Files: Beyond embedding metadata within JPEG images, this standard allows JUMBF boxes to exist as independent standalone files with the
.jumbfextension. These files use the media typeapplication/jumbf, enabling the separation of metadata from image content when embedding is impractical or undesirable.Embedding in JPEG Formats: The amendment explains how to embed JUMBF metadata in various JPEG formats, including JPEG 1 images (via JPEG XT Box Format), JPEG 2000, and JPEG XL. This ensures broad compatibility across different JPEG file types.
Implementation Guidelines: Detailed instructions for implementing the JUMBF box format are provided in Annex A, including the structure and referencing of content types like XML, JSON, and CBOR. Annexes address embedding strategies and referencing mechanisms, ensuring systematic integration into JPEG workflows.
Applications
ISO/IEC 19566-5:2023/Amd 1:2025 is highly relevant for applications that require sophisticated metadata handling within JPEG ecosystems:
Digital Asset Management: Enables richer metadata embedding and efficient compression, facilitating better organization, retrieval, and preservation of visual content.
Media Archiving and Preservation: Standalone JUMBF files provide a way to manage metadata separately from image data, which can be critical when original images should remain unmodified.
Content Delivery Networks and Streaming: Reduced metadata size via compression optimizes bandwidth and storage in transmission scenarios.
Software Development: Developers integrating metadata in JPEG-based applications can leverage these standards for compatibility with various JPEG formats and ensure efficient metadata compression.
Photography and Imaging Workflows: Embedding descriptive, rights management, or technical metadata directly into images enhances workflow automation and content integrity verification.
Related Standards
ISO/IEC 18181-2:2024 – JPEG XL Image Coding System Part 2: Provides a related file format specification that shares compression technologies with the Brob Box defined in this amendment.
IETF RFC 7932 – Brotli Compressed Data Format: Defines the Brotli compression algorithm used for compressing JUMBF payloads.
ISO/IEC 19566 Series: The broader JPEG systems standards addressing various aspects of JPEG file structures and metadata formats.
This amendment represents an important advance in the standardization of JPEG metadata handling, focusing on compression efficiency and flexible file structures. It supports evolving multimedia ecosystems by enabling better metadata integration, essential for modern image processing, archiving, and distribution technologies.
