22、 a worldwide 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
23、other activities, 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 t
24、he subject 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 condit
25、ions determined 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 Natio
26、nal Committees. 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
27、 in which 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
28、Publication 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 en
29、sure that 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
30、 any nature 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 r
31、eferenced 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. Th
32、e main task 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
33、efforts, 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 t
34、ransformed into International Standards. IEC 62224, which is a technical specification, has been prepared by IEC technical committee 100: Audio, video and multimedia systems and equipment.

40、nformation services are making progress and a new type of information distribution and network sharing service has gradually emerged into the market. It is capable of utilizing terabyte-sized home servers also in private homes. Under these circumstances, in distribution of content over shared networ
41、ks, it is crucial to establish digital rights management (DRM) technologies to protect the content from illegal copying and usage. A truly successful DRM system must be built on open worldwide specifications and provide maximum interoperability and user acceptance. An open interoperable specificatio
42、n that follows this technical specification is able to construct highly expandable PKI-based DRM, targeting usage between systems, considering the expansion of recent content distribution services and clients (console type AV equipment, PC, mobile phone terminal, automotive telematics terminal, and
43、so on). This technical specification gives protocol specifications for the exchange of license information among the DRM module, the description of specifications for license information and the encrypted content formats. During the development of this model, the main consideration was the use of co
44、ntents in consumer electronics equipment connected with a home server. Also considered were distribution, storage exchange and use of content between the distribution server and the destination client system, allowing for conditions approved by the rights holder, and without loss of convenience for
45、the users. The standardization and its popularization based on this model will enable interconnection between DRM modules allowing strong content protection in various content distribution services over networks such as the Internet and mobile phone networks.
