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 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, 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 the 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 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 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 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 Compression) tool.

Part 4:
Conformance testing
AMENDMENT 32: Frame-based Animated Mesh Compression
conformance
After 8.5.16, add the 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 Decomposition) 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 node 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 Requirements
BIFS streams shall comply with the specifications in 4.3.6 of ISO/IEC 14496-16:2004/Amd.2 and BitWrapper
in ISO/IEC 14496-11.Measurement procedure.
8.5.17.2.2 Tolerance
BIFS streams shall comply with the specifications in 4.3.6 of ISO/IEC 14496-1
