IEC 62448:2017

Multimedia systems and equipment - Multimedia e-publishing and e-books - Generic format for e-publishing

IEC 62448:2017 specifies a generic format for multimedia e-publishing employed for e-book data interchange among data preparers and publishers, satisfying a number of publishers’ requirements: revisable, extensible and heterogeneous logical structure. This fourth edition cancels and replaces the third edition, published in 2013 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) clarifying descriptions;
b) deleting redundant statements;
c) resolving mistakes and confusing terminologies.

Overview

IEC 62448:2017 (Edition 4.0) specifies a generic format for multimedia e‑publishing and e‑books intended for reliable e‑book data interchange between data preparers and publishers. The standard defines a revisable, extensible and heterogeneous logical structure for multimedia e‑publishing that supports complex page and block layouts, multimedia objects and interactive features. This fourth edition is a technical revision that clarifies descriptions, removes redundant statements and resolves terminology issues from the previous edition.

Key topics

• Generic format position and requirements - role of the format in the content creation/distribution model and mandatory properties (revisable, extensible, heterogeneous logical structure).
• Logical structure and semantics - how content is organized logically (pages, blocks, chapters) and the meaning of structural elements.
• Notation and terms - standardized terms and notation for consistent implementation and interchange.
• Element and attribute catalog - a comprehensive list of elements and attributes for e‑publishing objects (examples in the standard include TextBlock, ImageBlock, ButtonBlock, Sound, Font, PageStyle, TextStyle, BookInformation, TOC and navigation elements).
• Layout and block model - page/block layout, coordinate systems and block-level constructs to support rich page design and heterogeneous content.
• Multimedia streams and interactivity - support for image and sound streams, interactive buttons and window/pop‑up constructs.
• Annexes - normative annex describing formats such as BBeB Xylog and detailed element definitions.

Applications

IEC 62448 is practical for:

• Publishers and content preparers needing a standardized exchange format for complex multimedia e‑books.
• Authoring and conversion tool vendors implementing import/export, validation or transformation pipelines for e‑publishing assets.
• Rendering engines and e‑reader developers that must interpret structured page and block layouts, multimedia streams and interactive elements.
• Digital archives and libraries requiring a stable, revisable format for long‑term preservation and metadata exchange.

Typical uses include e‑book interchange between production systems, creating consistent multimedia layouts, enabling interactive content (buttons, pop‑ups, audio), and improving interoperability across e‑publishing toolchains.

Who should use this standard

• Publishers, content production teams and e‑book distributors
• Software developers of authoring tools, converters and e‑readers
• Systems integrators and digital preservation specialists

Related standards

For broader interoperability consider pairing IEC 62448 with other e‑publishing specifications and industry formats (for example EPUB and relevant IEC multimedia standards). Consult the IEC catalogue for updates, corrigenda and related technical documents.

Keywords: IEC 62448, e‑publishing standard, multimedia e‑publishing, e‑books format, e‑book interchange, e‑publishing tools, page layout, multimedia streams.
