9、on 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 respecti
10、ve 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
11、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 2. The main task of the joint technical committee is to prepare International Standards. Draft International Sta
12、ndards 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.

This replaces al
16、l text that previously followed Table A.45 up to but not including Table A.47. A.10.1 Codestream restrictions for digital cinema applications including archiving In addition to the profiles defined in Table A.10, five profiles are defined for digital cinema and archiving applications as detailed in
17、Table A.46. The first two, in form of Profile-3 and Profile-4, are primarily intended for distribution. In addition, the three profiles listed under profile indication numbers 5 to 7 are intended for archiving and production purposes. The two extended scalable profiles (Profile-5 and Profile-6) are
18、intended to be used for easily accessible archives. The long-term storage profile (Profile-7) is intended for original camera capture or post-production workflows.
