National bodies that are members of ISO or IEC
12、 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 interest. Other international organizations, gover
13、nmental 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 the rules given in the ISO/IEC Directives, Pa
14、rt 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 requires approval by at least 75 % of the national
15、 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 32 to ISO/IEC 14496-4:2004 was prepared by Joint Technical
16、Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. ISO/IEC 14496-16 introduced several animation models as methods of deforming a mesh. This Amendment deals with conformance of the FAMC (Frame-based Animated Mesh Comp
17、ression) tool. Amendment 32:2010 to CAN/CSA-ISO/IEC 14496-4-06ISO/IEC 14496-4:2004/Amd.32:2009(E) ISO/IEC 2009 All rights reserved 1Information technology Coding of audio-visual objects Part 4: Conformance testing AMENDMENT 32: Frame-based Animated Mesh Compression conformance After 8.5.16, add the
18、following new subclause: 8.5.17 Frame-based Animated Mesh Compression (FAMC) 8.5.17.1 Conformance Points 8.5.17.1.1 Covered functionalities The conformance points for FAMC cover The compression of different attributes per vertex, Different compression configurations (DCT, Lift, Layer-based Decomposi
19、tion) and possible combinations between, CABAC-based arithmetic encoding, Temporal, spatial and SNR scalability. The following subclauses specify the normative tests for verifying conformance of FAMC. Those normative tests make use of test data (bitstream test suites). FAMC is using the BitWrapper n
20、ode in a separate bitstream referred by a url. The following subclauses specify the normative tests for verifying conformance of FAMC compressed bitstreams and FAMC decoder. Those normative tests make use of test data (bitstream test suites). 8.5.17.2 Bitstream conformance 8.5.17.2.1 Conformance Req
