2、444-2:2004 (first edition, 2004-05-15) has been adopted withoutmodification (IDT) as CSA Standard CAN/CSA-ISO/IEC 15444-2:05, which has been approved as a NationalStandard of Canada by the Standards Council of Canada.ISBN 1-55397-965-6 October 2005The Canadian Standards Association (CSA),under whose
3、 auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.
4、CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal government
5、s in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supportin
6、g the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development
7、activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In add
8、ition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent se
9、rvice organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.For further information on CSA services, write toCanadia
10、n Standards Association5060 Spectrum Way, Suite 100Mississauga, Ontario, L4W 5N6CanadaThe Standards Council of Canada is the coordinating body of the National Standards system, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary
11、standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domestic and
12、international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose colle
13、ctive interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the n
14、ational interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of
15、the accredited standards development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization prepa
16、ring the standard.The responsibility for approving National Standards of Canada rests with theStandards Council of Canada270 Albert Street, Suite 200Ottawa, Ontario, K1P 6N7CanadaCette Norme nationale du Canada est offerte en anglais et en franais.Although the intended primary application of this St

25、 Add the following two paragraphs after the first paragraph: All features specified are in addition to the features defined by the JP2 file format and JPEG 2000 codestream profile 0; it is assumed that any reader capable of reading a JPX file is also capable of understanding every feature defined in
26、 the JP2 file format and decoding a JPEG 2000 profile 0 codestream. This box shall contain an accurate specification, to the extent as known by the writer, of all features in the file and an accurate specification of the set or sets of features required to display the image as intended by the writer
27、. NOTE If a JPX file contains no features other than those defined by the JP2 file format and JPEG 2000 codestream profile 0, or if the reader does not know of any features contained in the file beyond those base features, the Reader Requirements box will list zero standard features and zero vendor
28、features. Many features from previous revisions of this Recommendation | International Standard have been deprecated. Writers shall not include these features when creating or updating files. Readers shall ignore the contribution of those features when determining whether they can or cannot read the

Picture data is stored in component interleaved format, encoded at the bit depth as specified by the BPC field. This value is only permitted fo
43、r codestreams where all components are encoded at the same bit depth. When the bit depth of each component is not a multiple of 8, component values shall be packed into bytes so that no bits are unused between components. However, the value of the first component of each sample shall begin on a byte
44、 boundary and padding bits having value zero shall be inserted after the last component of the sample as necessary to fill out the remaining bits to the next byte boundary. When multiple component values are packed into a byte, the first component shall appear in the most significant bits of the byt
45、e. When a component is larger than a byte, its most significant bits shall appear in earlier bytes. 8) Clause A.3.1, Table A.21 Add the following clarification: IEEE numbers as used in the ISO/IEC 15444-2 codestream have to be written in big-endian order, using the following bit-assignments for enco
