29、s 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 electrical and electronic fields. To this end and in additio

30、n 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-governmental organizations liaising

31、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 IEC on technical matters exp

32、ress, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of sta

33、ndards, technical specifications, 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 International Standards transparently to the maximum extent possible in their

34、 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 b

35、e 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 all such patent rights. International Standard IEC 62289 has

36、been prepared by IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this standard is based on the following documents: CDV Report on voting 100/416A/CDV 100/481/RVC Full information on the voting for the approval of this standard can be found in the report on

37、 voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. The committee has decided that the contents of this publication will remain unchanged until 2007. At this date, the publication will be reconfirmed; withdrawn; replaced by a rev

38、ised edition, or amended. 6 62289 IEC:2002(E) VIDEO RECORDING HELICAL-SCAN DIGITAL VIDEO CASSETTE RECORDING FORMAT USING 12,65 MM MAGNETIC TAPE AND INCORPORATING MPEG-2 COMPRESSION FORMAT D-10 1 Scope This standard specifies the formatting for the recording of data blocks containing MPEG-2 compresse

39、d video, multiple channels of AES3 audio and associated data which form helical records on 12,65 mm tape in cassettes. This standard also defines the helical track record parameters, the content and format of the longitudinal records and the cassette physical specifications. The compressed video use

40、s the MPEG-2 compression which is defined by ISO/IEC 13818-2 with constraints as defined by Annex F. The compressed video channel supports frame frequencies of 30/1,001 Hz (hereafter referred to as 525/60 system) and 25 Hz (hereafter referred to as 625/50 system). 2 Normative references The followin
