12、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
13、. 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
14、, ISO/IEC JTC 1. 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. International Standard ISO/IEC 9281-2 was prepared b
15、y Joint Technical Committee ISO/IEC JTC 1, Information technology. ISO/IEC 9281 consists of the following parts, under the general title Information technology Picture coding methods: Part 1: Identification; Part 2: Procedure for registration. Annex A and Annex B form an integral part of this part o
16、f ISO/IEC9281.iv blankISO/IEC9281-2:1990(E) BSI 02-2000 1 1 Scope This part of ISO/IEC 9281 specifies the procedures to be followed by a Registration Authority in preparing, maintaining and publishing a register of identifiers allocated to picture coding methods. The identifiers to which this part o
17、f ISO/IEC 9281 refers are those described in ISO/IEC 9281-1. In identifier registered in accordance with this part of ISO/IEC 9281 serves as an identification of the picture coding method associated with it in the register. Apart from such identification, registration does not affect the status of t
18、he method concerned. Thus, the registration procedure must be clearly distinguished from the standardization processes. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 9281. At the time of publicati
19、on, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO/IEC 9281 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of cur
20、rently valid International Standards. ISO/IEC 9281-1:1990, Information technology Picture coding methods Part 1: Identification. 3 Registration Authority 3.1 The Registration Authority shall be an organization nominated by the ISO/IEC sub-committee concerned with picture coding and appointed by the
21、ISO/IEC Councils to act as the Registration Authority for the purpose of ISO/IEC9281. 3.2 The Registration Authority shall maintain a register of the allocated identifiers. The contents of this register shall be available upon request to national bodies that are members of ISO or IEC, to liaison org
22、anizations of ISO or IEC and to any interested party. 3.3 The Registration Authority shall maintain an updated list of the owners of picture coding methods recorded in the International Register. New registrations and any other pertinent communication concerning the register shall be sent to all per
23、sons on this list. The Registration Authority may request from time to time that owners confirm their continuing interest in receiving new registrations and drop from the list those having not confirmed such interest. 3.4 The registration documents do not specify the rules in accordance with which a
24、 picture coding method identified by an identifier must be used. The documents, for example standards, specifying such rules shall be mentioned in the registration documents. 4 Registration procedure With regard to the initial assignment of identifiers and of subsequent additions to the register, th
25、e responsibilities of the Registration Authority shall be a) to receive from Sponsoring Authorities (seeclause 9) applications for allocation of an identifier to be assigned to a picture coding method; b) to ascertain that the applications received are formally in accordance with this part of ISO/IE
26、C9281 and technically in accordance with ISO/IEC 9281-1; each application shall include a publicly available, complete description of the picture coding method to be identified; c) where required, to indicate to the Sponsoring Authority the changes needed to meet the requirements of b) above; d) to
27、circulate the proposals to the members of the picture coding sub-committee for a three-month information and comment period; e) to consider comments received and, when feasible, to incorporate them in the final document; f) to assign the identifier; g) to promulgate to all the national bodies and li
28、aison organizations of ISO and IEC the meaning that has been assigned to each identifier. 5 Withdrawal procedure 5.1 Withdrawal is a formal declaration by which the Sponsoring Authority informs the Registration Authority that it withdraws its support of the registered picture coding method. 5.2 Such
29、 a declaration may, but need not, be accompanied by a statement of the reasons for the withdrawal. 5.3 The Registration Authority shall inform the interested parties of the reception of such declarations. 5.4 Withdrawal has no effect on the registered method which shall remain in the register and co
30、ntinue to be identified by the allocated identifier.ISO/IEC9281-2:1990(E) 2 BSI 02-2000 6 Correction procedure 6.1 Material errors, for example typographical errors, drawing errors, shall be corrected by the Registration Authority as soon as detected. 6.2 New corrected and dated pages of the registe
31、r shall be issued. 7 Revision procedure 7.1 In general, no changes to registrations are permitted, as this would be contrary to the principles on which the registration scheme is based. 7.2 The Registration Authority may exceptionally grant a waiver to international, governmental organizations issui
32、ng internationally recognized and worldwide implemented standards. However, the possibility that a registration may be modified in future without allocation of a new PI byte shall be mentioned in the first application papers and in the register. 8 Appeal procedure Appeal against decisions of the Reg
