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 4 to ISO/IEC 14496-1:2001 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.

0xFF no object type specified
a
This type is used for all 14496-1 streams unless specifically indicated to the contrary. Scene
Description scenes, which are identified with StreamType=0x03 (see Table 7), using this object type
value shall use the BIFSConfig specified in subclause 9.3.5.2.2 of this specification.
b
This object type shall be used, with StreamType=0x03 (see Table 7), for Scene Description streams
that use the BIFSv2Config specified in subclause 9.3.5.3.2 of this specification. Its use with other
StreamTypes is reserved.
c
This object type shall be used, with StreamType=0x03 (see Table 7), for Scene Description streams
that use the BIFSConfigEx specified in subclause 8.7.6.1.2 of this specification. Its use with other
StreamTypes is reserved.
d
This object type shall be used, with StreamType=0x03 (see Table 7), for Scene Description streams
that use the AFXConfig specified in subclause 8.7.6.1.2 of this specification. Its use with other
StreamTypes is reserved.
e
Includes associated Amendment(s) and Corrigendum(a). The actual object types are defined in
ISO/IEC 14496-2 and are conveyed in the DecoderSpecificInfo as specified in ISO/IEC 14496-2, Annex K.
f
Includes associated Amendment(s) and Corrigendum(a). The actual object types are defined in
ISO/IEC 14496-3 and are conveyed in the DecoderSpecificInfo as specified in ISO/IEC 14496-3
subpart 1 subclause 6.2.1.
g
Streams with this value with a StreamType indicating a systems stream (values 1,2,3, 6, 7, 8, 9)
shall be treated as if the ObjectTypeIndication had been set to 0x01.

ISO/IEC 14496-1:2001/Amd.4:2003(E)
Append to 8.6.7.2:
For values of DecoderConfigDescriptor.objectTypeIndication that refers to extended BIFS
configuration (0x04), the decoder specific information is:
class BIFSConfigEx extends DecoderSpecificInfo : bit (8) tag = DecSpecificInfoTag
{
ExtendedBIFSConfig extBIFSConfig;
}

abstract aligned(8) expandable (.) class ExtendedBIFSConfig : bit (8) tag = 0x01.0xFF {
 //empty. To be filled by classes extending this class.
}

The class BIFSConfigEx contains an ExtendedBIFSConfig. ExtendedBIFSConfig is the base class for new
classes meant to hold decoder specific information. With this approach, new BIFS streams will have
streamType 3 and objectTypeIndication 3, but will use decoder configuration depending on the tag of the
ExtendedBIFSConfig.
For values of DecoderConfigDescriptor.objectTypeIndication that refers to AFX streams (0x05),
the decoder specific information is:
class AFXConfig extends DecoderSpecificInfo : bit(8) tag=DecSpecificInfoTag {
AFXExtDescriptor afxext;
}
abstract class AFXExtDescriptor extends BaseDescriptor : bit(8) tag = 0.100
{
}

AFXExtDescriptor is an abstract class used as a placeholder for an optional DecoderSpecificInfo defined in
this specification:
Table AMD4-1 — DecoderSpecificInfo for AFX streams
AFX stream DecoderSpecificInfo
MeshGrid See subclause 5.2.2.2 of ISO/IEC 14496-16.
WaveletSubdivisionSurface See subclause 5.1.1.1 of ISO/IEC 14496-16.
Other AFX streams None

and the tag refers to a specific node compression scheme as defined in Table AMD4-2.
Table AMD4-2 — AFX object code
AFX object code object
0x00 3D Mesh Compression
0x01 WaveletSubdivisionSurface
0x02 MeshGrid
0x03 CoordinateInterpolator

class ExtendedSLConfigDescriptor extends SLConfigDescriptor : bit(8)
tag=ExtSLConfigDescrTag {
SLExtensionDescriptor slextDescr[1.255];
}

Append to 10.2.3.2:
slextDescr – is an array of ExtensionDescriptors defined for ExtendedSLConfigDescriptor as specified in
10.2.3.3.

Insert new subclause 10.2.3.3 SLExtensionDescriptor syntax:
abstract class SLExtensionDescriptor : bit(8) tag=0 {

class DependencyPointer extends SLExtensionDescriptor: bit(8) tag= DependencyPointerTag {
bit(6) reserved;
bit(1) mode;
bit(1) hasESID;

if (hasESID)
{
 bit(16) ESID;
}
}
class MarkerDescriptor extends SLExtensionDescriptor: bit(8) tag=DependencyMarkerTag {
int(8) markerLength;
}

Insert new subclause 10.2.3.4 SLExtensionDescriptor semantics:
SLExtensionDescriptor is an abstract class specified so as to be the base class of sl extensions.
