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 11 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.
This Amendment adds the conformance testing for the combination of the SBR tool with the parametric stereo
tool as defined in Annex 8.A of ISO/IEC 14496-3:2006.

Part 4:
Conformance testing
AMENDMENT 11: Parametric stereo conformance
In subclause 6.5.1 File name conventions, insert the following row into Table 29 after the row for SBR (+AAC
LC):
Table 29 – File name conventions
PS (+SBR+AAC LC) al_sbr_ps_ al_sbr_ps_[_]
And add:
〈version〉 is either “bl” or ”ur” for the baseline or the unrestricted version of the parametric stereo decoding
algorithm respectively.
After subclause 6.6.17 SBR, add the following subclauses:
6.6.18 PS (Parametric Stereo)
6.6.18.1 Compressed data
6.6.18.1.1 Characteristics
The parametric stereo tool can be used in combination with (the combination of) the AAC LC AOT and the
SBR AOT, or with the SSC AOT.
If the parametric stereo tool is used in combination with the AAC LC AOT and the SBR AOT, the PS data shall
be stored as outlined in ISO/IEC 14496-3, Annex 8.A, Combination of the SBR tool with the parametric stereo
tool.
6.6.18.1.2 Test procedure
Each compressed data shall meet the syntactic and semantic requirements specified in ISO/IEC 14496-3. The
decoded data shall also meet the requirements defined in ISO/IEC 14496-3. If a syntactic element is not listed
below, no restrictions apply to that element. The reserved_ps element shall be encoded with the value zero.
6.6.18.1.2.1 Compressed MPEG-4 data payload
6.6.18.1.2.1.1 ps_data()
iid_mode: Shall be encoded with a value in the range of [0 5]. The values 6, 7 are reserved.
icc_mode: Shall be encoded with a value in the range of [0 5]. The values 6, 7 are reserved.
