27、SSION _ ENCODING GUIDELINES FOR PORTABLE MULTIMEDIA CE PRODUCTS USING MP4 FILE FORMAT WITH AVC VIDEO CODEC AND AAC AUDIO CODEC FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nati

28、onal 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 Reports, Publi

29、cly 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 and non- govern

30、mental 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 agreements of IEC on

31、 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 and are accepted

32、 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 international

33、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 indicated in the latter

34、. 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 IEC or its dire

35、ctors, 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 expenses arisin

36、g 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) Attention is dr

37、awn 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 task of IEC technical committees is to prepare International Standards. In exceptional circumstances

38、, 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, or the subject is still under technical development or where, for any other reason, there is the f

39、uture 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 transformed into International Standards. This Technical Specification cancels and replaces the first editio

40、n published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added 23,976 fps to all classes; TS 62592 IEC:2012(E) 7 b) added new class (class network SD); c) added some metadata for CE

41、content; d) inserted some editorial improvements and clarifications. IEC/TS 62592, which is a Technical Specification, has been prepared by technical area 6: Storage media, data structures, equipment and systems, of IEC technical committee 100: Audio, video and multimedia systems and equipment. The

42、text of this Technical Specification is based on the following documents: Enquiry draft Report on voting 100/1926/DTS 100/1970/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 b

43、een drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the

44、 publication will be 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. 8 TS 62592 IEC:2012(E) 0 Introduction 0.1 MP4 file format ISO base media file format, ISO/IEC 144

45、96-12, has been developed by ISO/IEC JTC 1/SC 29/WG 11 and WG1 as a common base media file format of audio, video and image applications. It provides a file format to contain timed media information for a presentation in a flexible, extensible format. The extensions to support specific codecs and sy

46、stems are specified as the series of standard ISO/IEC 14496. The MP4 file format (MPEG-4 file format), ISO/IEC 14496-14, is an extension to support MPEG-4 systems in ISO base media file format. The extension to support Advanced Video Coding (AVC), ISO/IEC 14496-10 and ITU-T H.264 1 , is standardized

47、 as AVC file format, ISO/IEC 14496-15. In this Technical Specification, the family of ISO base media file format is referred to as MP4 file format, which is the name widely used in the industry. The MP4 file format is designed very flexibly so that the series of the standard can be applied to variou

48、s kinds of applications and can bring the maximum performances for the applications. MP4 file format is adopted by various Consumer Electronics (CE) devices, e.g. broadcasting receivers, disc recorders / players, AV content distribution, portable AV recorders / players, and so on. In the CE audio, v

49、ideo and multimedia applications, MP4 file format with Advanced Video Coding (AVC), (ISO/IEC 14496-10 and ITU-T H.264) and Advanced Audio Coding (AAC), (ISO/IEC 13818-3 and ISO/IEC 14496-3), is employed most popularly. AVC (ISO/IEC 14496-10 and ITU-T H.264) specifies profiles and levels to ensure interoperability of decoding procedure of a video elementary stream, which fits various levels of application.
