22、ectrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co- operation on all questions concerning standardization in the eiectricai and electronic field
23、s. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International. governmental and non-governm
24、ental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the
25、 IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from ail interested National Committees. 3) The documents produced have the form of recommendations for international use and are
26、 published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, iEC National Committees undertake to apply IEC Intemational Standards transparently to the maximum extent possible in the
27、ir national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to
28、 be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or ali such patent rights. This Intemational Standard has been
29、 prepared by Working Group 1 of of EC Technical Committee 100: Audio, video and multimedia systems and equipment, under the responsibility of Technical Committee 1: Terminology. The text of this standard is based on the following documents: Full information on the voting for the approval of this sta
