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 3.
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 part of ISO/IEC 15444 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 15444-3 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, but is not published as
common text at this time.

ISO/IEC 15444-3:2002(E)
Introduction
This document specifies the use of the wavelet-based JPEG2000 codec for the coding and display of timed sequences of
images. It has been defined by ISO/IEC JTC 1 SC 29/WG 1 as part three of the JPEG2000 International Standard. In
this specification, a file format is defined, and guidelines for the use of the JPEG2000 codec for timed sequences are

supplied. The Motion JPEG2000 file format MJ2 is designed to contain one or more motion sequences of JPEG2000
images, with their timing, and also optional audio annotations, all composed into an overall presentation.

Motion JPEG2000 is expected to be used in a variety of applications, particularly where the codec is already available
for other reasons, or where the high-quality frame-based approach, with no inter-frame coding, is appropriate. These
application areas include:
� digital still cameras,
� error-prone environments such as wireless and the internet,
� PC-based video capturing,
� high quality digital video recording for professional broadcasting and motion picture production from film-based
to digital systems,
� and high-resolution medical and satellite imaging.
Motion JPEG2000 is a flexible format, permitting a wide variety of usages, such as editing, display, interchange, and
streaming.
The file structure is object-oriented; a file can be decomposed into constituent objects very simply, and the structure of
the objects inferred directly from their type.
Media-data is not ‘framed’ by the file format; the file format declarations that give the size, type and position of media
data units are not physically contiguous with the media data. This makes it possible to subset the media-data, and to use
it in its natural state, without requiring it to be copied to make space for framing. The meta-data is used to describe the
media data by reference, not by inclusion.
The file format does not require that a single presentation be in a single file. This enables both sub-setting and re-use of
content. When combined with the non-framing approach, it also makes it possible to include media data in files not
formatted to this specification (e.g. ‘raw’ files containing only media data and no declarative information, or file formats
already in use in the media or computer industries).
The file format is based on a common set of designs and a rich set of possible structures and usages. The same format
serves all usages; translation is not required. However, when used in a particular way (e.g. for local presentation), the
file may need structuring in certain ways for optimal behavior (e.g. time-ordering of the data). No normative structuring
rules are defined by this specification, unless a restricted profile is used.
Motion JPEG2000 is based on the MPEG-4 MP4 file format, and JPEG2000 is represented as a peer coding system to
MPEG4 visual, in this specification.

4 Compatibility and Technology derivation
4.1 Family Members
This is a standalone specification; it defines the file format for MJ2. However, it stands as a member of a family of
specifications with common formatting.
The other family members include:
� The JPEG2000 single image format, JP2.
� The MPEG-4 file format, MP4.
� The QuickTime file format, on which MP4 and this specification are based.
These specifications share a common definition for the structure of a file (a sequence of objects, called boxes here and atoms in
MP4 and QuickTime), and a common definition of the general structure of an object (the size and type).
All these specifications require that readers ignore objects that are unrecognizable to them.
This specification takes precedence over those from which it inherits, in any case where there are differences or conflicts;
however no such conflicts are known to exist.
4.2 MP4 Inheritance and Compatibility
Motion JPEG2000 is represented as a peer coding system to MPEG4 visual, in this specification. Data structures and concepts
that are held in common with these other specifications are defined to be compatible with them. Most boxes (atoms in MP4)
are defined identically; this includes:
Movie, Media Data, Track, Track Reference, Media, Media Header, Handler Reference, Media Information,
Hint Media Header, Data Information, Data Reference, Sample Table, Time to Sample, Sample Size, Sample to
Chunk, Chunk Offset, Free Space, Edit, Edit List, User Data, and Extension (UUID) boxes.
A number of boxes are used in a compatible fashion, but there are a number of fields in MP4 which, in that specification, have
required initial values but are ignored on reading, which are used here. This includes:
Movie Header, Track Header, Video Media Header, Sound Media Header,
The format of the Sample Description Box itself is the same, but a new VideoSampleDescription Box for motion JPEG2000 is
introduced within it; and likewise, a new Audio Sample Description format for raw audio is introduced.
4.3 JP2 Inheritance and Compatibility
The still image format, JP2, defines a number of boxes. The following boxes from that specification shall be present. If the
JP2 specification requires a particular position (e.g. first in the file), that positioning shall be followed here:
1) The JP2 'family' signature box ‘jP ’.
2) The file type compatibility box ‘ftyp’.
In the file type compatibility box, the brand shall be 'mjp2' for files conforming to this specification, and 'mjp2' shall be a
member of the compatibility list.
It is permissible under this specification to make a file that adheres to both this specification and the JP2 specification. In that
case:
1) The compatibility list shall include all the compatible brands
2) The objects (boxes or atoms) required by the JP2 specification shall also be present.
3) The objects (boxes or atoms) optional in the JP2 specification may also be present.
A still image reader, reading a file which contains both a presentation (conformant to this specification) and a still image, would
'see' only the still image. Likewise a motion reader would 'see' only the presentation. A more powerful reader may display
both, or offer the user a choice.
The JP2 specification includes an optional IPR (Intellectual Property Rights) box which is therefore also optional in this
specification. Among other issues this addresses unique identification and protection of content.

ISO/IEC 15444-3:2002(E)
4.4 Conformance
Implementations of Motion JPEG2000 decoders shall support JPEG2000 image sequences, as well as raw and twos-
complement audio if audio output is available. They may also support compressed audio, using MP4 formats, or other track
types from MPEG-4. The support of such MPEG-4 tracks is not required; however, readers shall not fail if they are present. If
MPEG-4 composition (BIFS) is used, then the simple composition used in this specification should also be set up in such a way
that a reader not implementing BIFS will display a suitable result.
Files conformant with this specification shall contain at least one Motion JPEG2000 video track. They may contain more video
tracks, uncompressed audio, or compressed MP4 audio.
4.5 Profiles and Levels
There are two tools for profiling Motion JPEG2000 files.
The first consists of the optional specification of tools and levels of the JPEG2000 coding system (codestream features). These
are indicated in the optional sample description extension JP2 Profile Box (see below 5.3.16).
The second tool allows a file overall to be identified as belonging to a definition which forms a proper subset of the general
specification. Such definitions might restrict such features as:
� the use of data references, and multiple files
� the layout order of the boxes, and the data within the boxes (e.g. that data is in time order and interleaved)
� the use of profiles of the JPEG2000 codestream
� the existence of other tracks, and their format (e.g. audio, MPEG-7, etc.).
The conformance to these restricted profiles is indicated in the file type box by the addition of the compatible profiles as brands
within the compatibility list. "Annex A File and Codestream profiles" defines the available profiles in this specification.
5 File organization
5.1 Presentation structure
5.1.1 File Structure
A presentation may be contained in several files. One file contains the meta-data for the whole presentation, and is formatted to
this specification. This file may also contain all the media data, whereupon the presentation is self-contained. The other files, if
used, are not required to be formatted to this specification; they are used to contain media data, and may also contain unused
media data, or other information. This specification concerns the structure of the presentation file only. The format of the
media-data files is constrained by this specification only in that the media-data in the media files must be capable of description
by the meta-data defined here.
These other files may be MJ2 files, JPEG2000 image files, MPEG-4 files containing JPEG2000 images, or other formats
containing JPEG2000 images. Only the media data itself, such as the JPEG2000 images, is stored in these other files; all
timing and framing (position and size) information is in the MJ2 file, so the ancillary files are essentially free-format.
If an MJ2 file contains hint tracks, the media tracks that reference the media data from which the hints were built shall remain
in the file, even if the data within them is not directly referenced by the hint tracks.
5.1.2 Object Structure
The file is structured as a sequence of objects; some of these objects may contain other objects. The sequence of objects in the
file shall contain exactly one presentation meta-data wrapper (the Movie Box). It is usually close to the beginning or end of the
file, to permit its easy location. The other objects found at this level may be free space, or media data boxes.
The fields in the objects are stored with the most significant byte first, commonly known as network byte order or big-endian
format.
5.1.3 Meta Data and Media Data
The meta-data is contained within the meta-data wrapper (the Movie Box); the media data is contained either in the same file,
within Media Data Box(es), or in other files. The media data is composed of images or audio data; the media data objects, or
media data files, may contain other un-referenced information.
5.1.4 Track Identifiers
The track identifiers used in an MJ2 file are unique within that file; no two tracks shall use the same identifier.

---------------------- Page: 9 ----------------------
ISO/IEC 15444-3:2002(E)
The next track identifier value in the movie header generally contains a value one greater than the largest track identifier value
found in the file. This enables easy generation of a track identifier under most circumstances. However, if this value is equal to
ones (32-bit unsigned maxint), then a search for a free track identifier is needed for all additions.
5.1.5 Visual Composition
Composition of multiple image sequences in a 2D environment can be achieved by using multiple video tracks which overlap in
time. Their composition is defined by the following structures:
� The matrix in the track header specifies their positioning and scaling.
� The layer field in the track header specifies the front-to-back ordering of the tracks.
� The graphics mo
