15、wide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other ac
16、tivities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subje
17、ct dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions det
18、ermined by agreement between the two organizations. 2) The formal decisions or agreements of 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 all interested IEC National Comm
19、ittees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in whic
20、h they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publicat
21、ion and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure tha
22、t they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nat
23、ure whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the reference
24、d publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main t
25、ask of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts,
26、 or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transform
27、ed into International Standards. IEC 62436, which is a technical specification, has been prepared by technical area 4: Digital system interfaces and protocols, of IEC technical committee 100: Audio, video and multimedia systems and equipment. 4 TS 62436 IEC:2008(E) The text of this technical specifi
28、cation is based on the following documents: Enquiry draft Report on voting 100/1231/DTS 100/1334/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with
29、 the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be
30、transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. TS 62436 IEC:2008(E) 5 INTRODUCTION Various IEC standards have included methods for transmission of copy control infor
31、mation at the time when they were developed. For instance, IEC 61119-6 defines copyright status bit for DAT recorder, and IEC 60958-3 defines the L bit that is specified in IEC 61119-6. The current consumer products become more complex and use the many IEC standards in one product. For instance, a D
32、VD player produces its high quality audio signal securely through IEC 61883-6, it also performs CD quality audio signal through IEC 60958 or IEC 61937, and the DVD player can produce audio signals through the other interface using IEC 60958 conformant data format, defined in IEC 61883-6. Another exa
33、mple is a digital video recorder with hard disk drive or DVD that produces audio signal to the other audio recorder using IEC 60958 or IEC 61883-6. These consumer products use many interface standards and should give copy control information and other information appropriately. This guideline descri
34、bes the relation between digital interface standards, the relation of copy control information and related information, the method for information implementation. 6 TS 62436 IEC:2008(E) GUIDELINE FOR IMPLEMENTATION OF COPY CONTROLLED MULTIMEDIA INTERFACE 1 Scope This Technical Specification gives a

NOTE 2 SCMS is contained in the IEC 60958 conformant data format. 4.2 Relation between IEC standards Figure 1 shows the relat
45、ion between digital audio interface standards IEC 60958, IEC 61937 and IEC 61883-6. IEC 60958-1 is the fundamental standard of these related standards, and it defines the basic structure. The application standards derived form IEC 60958-1 for the linear PCM audio data transmission are IEC 60958-3 fo
46、r consumer use and IEC 60958-4 for professional use. IEC 61937 is derived from IEC 60958, it specifies the data packet structure based on IEC 60958-1, it is mainly for the transmission of compressed audio data. IEC 61937-1 and IEC 61937-2 specify the general structure. In part 1 and part 2 of IEC 61
47、937, transmission method for the specific compressed audio format are specified from part 3 to part 9. Also IEC 62105 specifies the receiver data transmission using IEC 61937-1 structure. IEC 61883-6 specifies IEC 60958 conformant data format, this format defines IEC 60958-1 structure in IEC 61883-6
48、. IEC 60958 conformant data format can transmit IEC 60958-1 and all of its derivative standards. IEC 60958 conformant data format can be used in any other interface specification applying the definition of the structure of IEC 60958-1. 8 TS 62436 IEC:2008(E) Figure 1 The relationship between IEC sta
