28、ERNATIONAL ELECTROTECHNICAL COMMISSION _ MULTIMEDIA SYSTEMS AND EQUIPMENT MULTIMEDIA E-PUBLISHING AND E-BOOKS READERS FORMAT FOR E-PUBLISHING FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical commi
29、ttees (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 activities, IEC publishes International Standards, Technical Specifications, Technical
30、 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 subject dealt with may participate in this preparatory work. International, governmental
31、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 determined by agreement between the two organizations. 2) The formal decisions or agree
32、ments 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 Committees. 3) IEC Publications have the form of recommendations for international use a
33、nd 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 which they are used or for any misinterpretation by any end user. 4) In order to promote
34、 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 Publication and the corresponding national or regional publication shall be clearly indicate
35、d 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 that they have the latest edition of this publication. 7) No liability shall attach to
36、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 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
37、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 referenced publications is indispensable for the correct application of this publication. 9)
38、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. International Standard IEC 62524 has been prepared by technical area 10: Multimedia e- publish
39、ing and e-books, of IEC technical committee 100: Audio, video and multimedia systems and equipment. This bilingual version, published in 2009-04, corresponds to the English version. The text of this standard is based on the following documents: CDV Report on voting 100/1376/CDV 100/1487/RVC Full inf
40、ormation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. 62524 IEC:2009 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee
41、 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 reconfirmed, withdrawn, replaced by a revised
42、edition, or amended. 6 62524 IEC:2009 INTRODUCTION Markets for multimedia e-book and e-publishing require standardization of formats for e-book data interchange among related parties: authors, data preparers, publishers and readers. The formats are classified into submission format, generic format a
43、nd readers format. The submission format has to support an interaction between authors and data preparers. The generic format has to provide an interchange format for data preparers and publishers and therefore should be reading-device-independent. The readers format depends on e- publishing equipme
44、nt. 62524 IEC:2009 7 MULTIMEDIA SYSTEMS AND EQUIPMENT MULTIMEDIA E-PUBLISHING AND E-BOOKS READERS FORMAT FOR E-PUBLISHING 1 Scope This International Standard specifies a readers format for multimedia e-publishing employed for e-book data interchange among publishers and readers, satisfying a number
45、of readers requirements such as being non-revisable, equipment-adaptive and application-adaptive. NOTE This International Standard does not address the following issues: elements necessary for final print reproduction only; rendering issues related to physical devices; metadata issues for document m
46、anagement; security issues such as DRM for document. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includin
47、g any amendments) applies.
