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 12 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.

Add the following subclauses after subclause 8.5.7:
8.5.8 PointTexture Bitstream Specification
PointTexture node in ISO/IEC 14496-16 has the depth information and the color information. PointTexture
represents an object with an array of pixels viewed from a single camera location. Each PointTexture pixel is
represented by its color, depth (the distance from the pixel to the camera), and a few other properties
assisting PointTexture rendering. There can be multiple pixels along each line of sight, and thus a
PointTexture usually consists of multiple layers. A PointTexture typically contains a large amount of data: a
realistic image requires a higher sampling density and a huge amount of data. Therefore, the compression of
PointTexture images should be done efficiently.
The PointTexture compression is a tool to compress the PointTexture node efficiently.
8.5.8.1 Conformance Points
8.5.8.1.1 Covered functionalities
The conformance points for PointTexture compression cover lossless compression and lossy compression.
These functionalities relate to the compressed representation of PointTexture node carried by BitWrapper
node as described in ISO/IEC 14496-11.
As for carriage of compressed representation of PointTexture node using BitWrapper node, it can be carried
either in a separate stream or within the scene stream (BIFS stream). Therefore, PointTexture compression
shall also be tested together with this node.
The following subclauses specify the normative tests for verifying the conformance of PointTexture
compressed bitstreams and PointTexture decoder. Those normative tests make use of test data (bitstream
test suites).

ISO/IEC 14496-4:2004/Amd.12:2007(E)
8.5.8.2 Bitstream conformance
8.5.8.2.1 Conformance Requirements
BIFS streams shall comply with the specifications for PointTexture compression in ISO/IEC 14496-16 and
BitWrapper in ISO/IEC 14496-11.
8.5.8.2.2 Measurement procedure
Syntax of the BIFS stream shall meet the requirements of PointTexture compression in ISO/IEC 14496-16 and
BitWrapper in ISO/IEC 14496-11.
8.5.8.2.3 Tolerance
There is no tolerance for bitstream syntax checking. The diagnosis is pass or fail.
8.5.8.3 Terminal conformance
8.5.8.3.1 Conformance Requirements
A compliant decoder shall implement a decoding process that is equivalent to the one specified in
ISO/IEC 14496-16 and meets all the general requirements, defined in the document, which apply for the
functionalities considered. The decoder shall decode bitstreams with any options or parameters with values
permitted for the functionalities. In the case of using BIFS for scene representation, the decoding process that
is specified in ISO/IEC 14496-1:2004 shall also be implemented.
8.5.8.3.2 Test Bitstreams
Purpose 1 (URL): Exercise the lossless and lossy compression functionality of MPEG-4 PointTexture
compression carried in a separate stream from the scene stream.
Purpose 2 (Buffer): Exercise the lossless and lossy compression functionality of MPEG-4 PointTexture
compression carried in the scene stream.

8.5.8.3.4 Tolerance
The diagnosis is to check whether the field data (depth, color, width, height, depthNbBits) of PointTexture
node that is decoded from “.mp4” files correspond with the node included in the provided reference “.txt” files.
8.5.9 BBA stream updates for Morph-based animation
The BBA stream syntax was updated in ISO/IEC 14496-16 in order to represent in a BBA animation frame,
the values of the weights associated to each target shape in a MorphShape node. The morph is the third
surface deformer that can be represented in a BBA data (with bones and muscles). A BBA animation frame
can contain data for several MorphShape nodes.
