Foreword

ISO (the lnternational Organization for Standardization) and IEC (the lnternational Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of lnternational Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work.

lnternational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3

In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft lnternational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an lnternational 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 Amendment may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 2 to lnternational Standard ISO/IEC 13818-6:1998 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
