Overview
IEC 62524:2009 - Multimedia systems and equipment - Multimedia e-publishing and e-books - Reader’s format for e-publishing - specifies a reader’s format for multimedia e-publishing used in e-book data interchange between publishers and readers. The standard defines the reader’s format as the final, device-targeted representation of a multimedia e-book (text, graphics, sound and/or video) produced by a publisher from a device-independent generic format. Key attributes emphasized include being non-revisable, equipment-adaptive, and application-adaptive. IEC 62524:2009 is Edition 1.0 (2009-02) and contains a normative annex describing a C‑XMDF reader’s format.
Key topics and technical requirements
- Role in the content workflow: Establishes where reader’s format fits in the content creation/distribution chain - Author → Data preparer → Publisher → Reader - and clarifies publisher responsibilities for converting generic formats to reader formats.
- Reader’s format requirements:
- Non-revisable: Final form intended for viewing rather than editing, simplifying processing for reading devices.
- Equipment-adaptive / Application-adaptive: Formats must be tailored to device constraints (CPU, memory, display size) and application needs; lighter binary structures and pre-calculated layout may be used for low-resource devices.
- Legibility: Encourages attention to page layout and typography to ensure comfortable reading; supports fixed-page and flow layouts depending on device targets.
- Scope limits: The standard does not address final print-only elements, low-level rendering tied to specific physical devices, metadata management for document workflows, or DRM/security mechanisms.
- Normative content: Annex A provides a concrete reader’s format (C‑XMDF) and includes file types, data structures, tags, and conformance levels (see tables and figures in the standard).
Applications and who uses it
- E-book publishers converting generic e-book assets into device-ready packages for distribution.
- Content preparers and editors who implement publishing pipelines that produce final reader files.
- Reading-device manufacturers and firmware developers ensuring device compatibility with standardized reader formats.
- Platform and app developers building e-reader software able to render standardized reader’s formats efficiently.
- Libraries, aggregators, and standards bodies adopting interoperable formats for distribution and long-term access.
