28、 La CEI (Commission Electrotechnique Internationale) est une organisation mondiale de normalisation composede lensemble des comits lectrotechniques nationaux (Comits nationaux de la CEI). La CEI a pour objet defavoriser la coopration internationale pour toutes les questions de normalisation dans les

29、 domaines dellectricit et de llectronique. A cet effet, la CEI, entre autres activits, publie des Normes internationales.Leur laboration est confie des comits dtudes, aux travaux desquels tout Comit national intress par lesujet trait peut participer. Les organisations internationales, gouvernemental

30、es et non gouvernementales, enliaison avec la CEI, participent galement aux travaux. La CEI collabore troitement avec lOrganisationInternationale de Normalisation (ISO), selon des conditions fixes par accord entre les deux organisations.2) Les dcisions ou accords officiels de la CEI concernant les q

31、uestions techniques reprsentent, dans la mesuredu possible un accord international sur les sujets tudis, tant donn que les Comits nationaux intressssont reprsents dans chaque comit dtudes.3) Les documents produits se prsentent sous la forme de recommandations internationales. Ils sont publiscomme no

32、rmes, rapports techniques ou guides et agrs comme tels par les Comits nationaux.4) Dans le but dencourager lunification internationale, les Comits nationaux de la CEI sengagent appliquer defaon transparente, dans toute la mesure possible, les Normes internationales de la CEI dans leurs normesnationa

33、les et rgionales. Toute divergence entre la norme de la CEI et la norme nationale ou rgionalecorrespondante doit tre indique en termes clairs dans cette dernire.5) La CEI na fix aucune procdure concernant le marquage comme indication dapprobation et sa responsabilitnest pas engage quand un matriel e

38、isingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International

39、Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC

40、 collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opi

41、nion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the

42、National Committees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the correspondin

43、g national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attention is drawn to the possibility that some of t

44、he elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61834-7 has been prepared by subcommittee 100B, Audio, videoand multimedia information storage systems, of IEC

45、 technical committee 100: Audio, video andmultimedia systems and equipment.The text of this standard is based on the following documents:FDIS Report on voting100B/284/FDIS 100B/290/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in th
