11、ational 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 technical committees established by the respective organization to deal with particular fie

12、lds 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 part in the work. In the field of information technology, ISO and IEC have established a

13、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 International Standards. Draft International Standards adopted by the joint technical commi

14、ttee 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 some of the elements of this part of ISO/IEC 14496 may be the subject of patent rights. ISO

15、 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 of audio, picture, multimedia and hypermedia information. This second edition cancels and

16、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 objects: Part 1: Systems Part 2: Visual Part 3: Audio Part 4: Conformance testing Part 5: Refere

18、reproduction or networking permitted without license from IHS-,-,-ISO/IEC 14496-5:2001(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

19、 models used in the process of developing the standard. Due to the delay between 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 t

20、o the fact that these encoders are provided for the purpose of creating bitstreams 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 techni

21、ques used for encoding are not specified by this specification.

23、ative in the sense that any conforming implementation of the software, taking the same conformant bitstreams, using the 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 refe

24、rence software. Although the decoding software is considered normative, it cannot add anything to the textual technical 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 s

25、oftware is catalogued in clauses 3, 4 and 5. This software accepts elementary streams encoded according to the normative 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 norma

26、tive part of this specification, attention is drawn to the fact that the implementation techniques used in this software 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

27、processes described in parts 1, 2, 3 and 6 of ISO/IEC 14496. b) Elementary stream encoding software is catalogued in Annex 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 synta

28、x described in parts 1, 2 and 3 of ISO/IEC 14496. The techniques used for encoding are not specified by this specification, 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 devel

29、opers of the standard, but may not conform to the normative specifications given in parts 1, 2, 3 and 6 of ISO/IEC 14496. File locations given in this part of ISO/IEC 14496 are expressed relative to its location in the source tree. 2 Copyright disclaimer for software modules Each source code module
