9、rved Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through t

10、echnical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take

11、 part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare I

12、nternational Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that s

13、ome of the elements of this part of ISO/IEC 14496 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 14496-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding

14、of audio, picture, multimedia and hypermedia information. This second edition cancels and replaces the first edition (ISO/IEC 14496-5:2000), which has been technically revised. ISO/IEC 14496 consists of the following parts, under the general title Information technology Coding of audio-visual object

16、5:2001(E) ISO/IEC 2001 All rights reserved vIntroduction This part of ISO/IEC 14496 contains simulation software for tools defined in parts 1, 2, 3 and 6 of ISO/IEC 14496. This software has been derived from verification models used in the process of developing the standard. Due to the delay between

17、 acceptance of a tool and its availability in source code form, the source for some tools described in other parts of ISO/IEC 14496 may not be present. Where bitstream encoding software is provided, attention is called to the fact that these encoders are provided for the purpose of creating bitstrea

18、ms with normative syntax. The performance of these encoders should not be taken as indicative of that which can be obtained from implementations where quality and computational optimization are given priority. The techniques used for encoding are not specified by this specification. INTERNATIONAL ST

19、ANDARD ISO/IEC 14496-5:2001(E) ISO/IEC 2001 All rights reserved 1Information technology Coding of audio-visual objects Part 5: Reference software 1 Scope Reference software is normative in the sense that any conforming implementation of the software, taking the same conformant bitstreams, using the

20、same output file format, will output the same file. Complying ISO/IEC 14496 implementations are not expected to follow the algorithms or the programming techniques used by the reference software. Although the decoding software is considered normative, it cannot add anything to the textual technical

21、description included in parts 1, 2, 3 and 6 of ISO/IEC 14496. The software contained in this part of ISO/IEC 14496 is divided into three categories: a) Elementary stream decoding software is catalogued in clauses 3, 4 and 5. This software accepts elementary streams encoded according to the normative

22、 specification in parts 1, 2, 3 and 6 of ISO/IEC 14496 and decodes the streams into the media types associated with each elementary stream. While this software appears in the normative part of this specification, attention is drawn to the fact that the implementation techniques used in this software

23、 are not considered normative several different implementations could produce the same result but the software is considered normative in that it correctly implements the decoding processes described in parts 1, 2, 3 and 6 of ISO/IEC 14496. b) Elementary stream encoding software is catalogued in Ann

24、ex A (informative). This software creates elementary streams from associated media types. The encoders are provided as a means to obtain elementary streams with the normative syntax described in parts 1, 2 and 3 of ISO/IEC 14496. The techniques used for encoding are not specified by this specificati

25、on, and the quality and complexity of these encoders has not been optimized. c) Utility software is catalogued in Annex B (informative). This software was found useful by the developers of the standard, but may not conform to the normative specifications given in parts 1, 2, 3 and 6 of ISO/IEC 14496
