Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form
the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the
development of International Standards through technical committees established by the respective organization to deal
with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest.
Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International Standards
adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 15444-6 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee
SC 29, Coding of audio, picture, multimedia and hypermedia information, in collaboration with ITU-T. The identical
text is published as Rec. ITU-T T.805 (01/2012).
This second edition is a consolidation of the first edition (ISO/IEC 15444-6:2003) and
ISO/IEC 15444-6:2003/Amd.1:2007.
ISO/IEC 15444 consists of the following parts, under the general title Information technology — JPEG 2000 image
coding system:
– Part 1: Core coding system
– Part 2: Extensions
– Part 3: Motion JPEG 2000
– Part 4: Conformance testing
– Part 5: Reference software
– Part 6: Compound image file format
– Part 8: Secure JPEG 2000
– Part 9: Interactivity tools, APIs and protocols
– Part 10: Extensions for three-dimensional data
– Part 11: Wireless

INTERNATIONAL STANDARD
RECOMMENDATION ITU-T
Information technology – JPEG 2000 image coding system:
Compound image file format
1 Scope
This Recommendation | International Standard defines a normative but optional file format for storing compound
images using the JPEG 2000 file format family architecture. This format is an extension of the JP2 file format defined
in Rec. ITU-T T.800 | ISO/IEC 15444-1 Annex I and uses boxes defined for both the JP2 file format and the JPX file
format defined in Rec. ITU-T T.801 | ISO/IEC 15444-2 Annex M. This Recommendation | International Standard is
useful for applications storing multiple pages, images with mixed content, and/or images that need more structure than
provided in JP2.
Applications that implement this file format shall implement it as described in this Recommendation | International
Standard. This Recommendation | International Standard:
– specifies a binary container for multiple bi-level and continuous-tone images used to represent a
compound image;
– specifies a mechanism by which multiple images can be combined into a single compound image, based
on the mixed raster content (MRC) model;
– specifies a mechanism for grouping multiple images in a hierarchy of layout objects, pages and page
collections;
– specifies a mechanism for storing JPEG 2000 and other compressed image data formats;
– specifies a mechanism by which metadata can be included in files specified by this Recommendation |
International Standard.
2 Normative references
The following Recommendations and International Standards contain provisions which, through reference in this text,
constitute provisions of this Recommendation | International Standard. At the time of publication, the editions indicated
were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this
Recommendation | International Standard are encouraged to investigate the possibility of applying the most recent
edition of the Recommendations and Standards listed below. Members of IEC and ISO maintain registers of currently
valid International Standards. The Telecommunication Standardization Bureau of the ITU maintains a list of currently
valid ITU-T Recommendations.
