Nat

35、ional 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 fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interes

36、t. 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 joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with th

37、e rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard require

38、s 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 document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 2 to ISO/IEC 230

40、n technology MPEG audio technologies Part 1: MPEG Surround AMENDMENT 2: Reference software After Clause 8, add a new clause, Reference software, as given below: 9 Reference software 9.1 Reference software structure 9.1.1 Introduction This clause contains simulation software for MPEG Surround as defi

41、ned in clauses 1 to 7 and Annexes A to J of ISO/IEC 23003-1. This software has been derived from verification models used in the process of developing the standard. Reference software is normative in the sense that it correctly implements the MPEG Surround decoding processes described in ISO/IEC 230

42、03-1. Complying ISO/IEC 23003-1 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 description of MPEG Surround included in ISO

43、/IEC 23003-1. The software contained in this clause 9 and in Annex K is divided into three categories: a) Bitstream decoding software is catalogued in subclause 9.2. This software accepts bitstreams encoded according to the normative specification in ISO/IEC 23003-1 and decodes the streams into the

44、audio signals associated with each bitstream. 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 are not considered normative several different implementations could produce the same result

45、but the software is considered normative in that it correctly implements the MPEG Surround decoding processes described in ISO/IEC 23003-1. b) Bitstream encoding software is catalogued in Annex K.1 (informative). This software creates bitstreams from associated audio signals. The encoders are provid

46、ed as a means to obtain bitstreams with the normative syntax described in ISO/IEC 23003-1. 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 K.2 (informative).

47、This software was found useful by the developers of the standard, but may not conform to the normative specifications given in ISO/IEC 23003-1. File locations given in this document are expressed relative to this documents location in the source tree. Amendment 2:2009 toCAN/CSA-ISO/IEC 23003-1-08ISO
