17、erved vForeword 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
18、 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 ta
19、ke 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
20、 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
21、 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, Codin
22、g of audio, picture, multimedia and hypermedia information, in collaboration with ITU-T, but is not published as common text at this time.

24、is document specifies the use of the wavelet-based JPEG2000 codec for the coding and display of timed sequences ofimages. It has been defined by ISO/IEC JTC 1 SC 29/WG 1 as part three of the JPEG2000 International Standard. Inthis specification, a file format is defined, and guidelines for the use o
25、f the JPEG2000 codec for timed sequences aresupplied. The Motion JPEG2000 file format MJ2 is designed to contain one or more motion sequences of JPEG2000images, with their timing, and also optional audio annotations, all composed into an overall presentation.Motion JPEG2000 is expected to be used in
26、 a variety of applications, particularly where the codec is already availablefor other reasons, or where the high-quality frame-based approach, with no inter-frame coding, is appropriate. Theseapplication areas include:G78 digital still cameras,G78 error-prone environments such as wireless and the i
27、nternet,G78 PC-based video capturing,G78 high quality digital video recording for professional broadcasting and motion picture production from film-basedto digital systems,G78 and high-resolution medical and satellite imaging.Motion JPEG2000 is a flexible format, permitting a wide variety of usages,
28、 such as editing, display, interchange, andstreaming.The file structure is object-oriented; a file can be decomposed into constituent objects very simply, and the structure ofthe objects inferred directly from their type.Media-data is not framed by the file format; the file format declarations that
29、give the size, type and position of mediadata units are not physically contiguous with the media data. This makes it possible to subset the media-data, and to useit in its natural state, without requiring it to be copied to make space for framing. The meta-data is used to describe themedia data by r
30、eference, 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 ofcontent. When combined with the non-framing approach, it also makes it possible to include media data in files notformatted to this specification (e.
31、g. raw files containing only media data and no declarative information, or file formatsalready 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 formatserves all usages; translation is not requir
32、ed. However, when used in a particular way (e.g. for local presentation), thefile may need structuring in certain ways for optimal behavior (e.g. time-ordering of the data). No normative structuringrules are defined by this specification, unless a restricted profile is used.Motion JPEG2000 is based
33、on the MPEG-4 MP4 file format, and JPEG2000 is represented as a peer coding system toMPEG4 visual, in this specification.1 ScopeThis document specifies the use of the wavelet-based JPEG2000 codec for the coding and display of timed sequences of images(motion sequences), possibly combined with audio,
34、 and composed into an overall presentation. In this specification, a fileformat is defined, and guidelines for the use of the JPEG2000 codec for motion sequences are supplied.2 Normative referencesThe following Recommendations and International Standards contain provisions which, through reference i

However, it stands as a member of a family ofspecifications with common formatting.The other family members include:G78 The JPEG2000 single image format, JP2.G78 The MPEG-4 file format, MP4.G78 The QuickTime file format, on which MP4 and this specification
45、 are based.These specifications share a common definition for the structure of a file (a sequence of objects, called boxes here and atoms inMP4 and QuickTime), and a common definition of the general structure of an object (the size and type).All these specifications require that readers ignore objec
