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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Information technology — JPEG XR image coding system —
Part 2:
Image coding specification
AMENDMENT 1: Media type specification
Introduction
Replace paragraph 12 with the following:
The main body of this document specifies the syntax and semantics of JPEG XR coded images and the
associated decoding process that produces an output image from a coded image. Annex A specifies
a tag-based file storage format for storage and interchange of such coded images. Annex B specifies
profiles and levels, which determine conformance requirements for classes of encoders and decoders.
Aspects of colour imagery representations and colour management are discussed in Annex C. The
typical expected encoding process is described in Annex D. Annex E contains a media type specification
for images encoded according to the tag-based format specified in Annex A for use in various Internet
protocols. Annex F lists patent rights notifications. Annexes A, B, and E are an integral part of this
document and contain normative specifications.
