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 14496-4:2004 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.

Part 4:
Conformance testing
AMENDMENT 4: IPMPX conformance extensions
Add the following clauses at the end of SNHC section:
9 Conformance for MPEG-4 IPMP Extension
9.1 Introduction
This clause is specified for the conformance test of ISO/IEC 14496-1. In this clause, except where stated
otherwise, the following terms are used for practical purposes:
The term “System bitstream” means the multiplexed MPEG-4 system stream which has at least IOD and OD
stream as specified in ISO/IEC 14496-1.
The term ‘IPMP bitstream’ means an MPEG-4 system bitstream with information of IPMP Extension protection,
including IPMP Descriptor, IPMP Stream, IPMP Tool List.
The term ‘IPMP Information’ means IPMP Descriptor, IPMP Tool List, and IPMP Stream that come from the
IPMP bitstream.
The term ‘IPMP Data’ means these IPMP data extended from IPMP_Data_BaseClass or other specific IPMP
data to assist IPMP protection, these IPMP Data can be carried in either IPMP Descriptor, IPMP Stream, or
IPMP Messages.
The term “IPMP Message” means the IPMP messages passed between terminal and IPMP tools via a non-
normative messaging interface.
The term 'IPMP terminal' means a MPEG-4 terminal with IPMP Extension capability as specified in
ISO/IEC 14496-1.
If any statement stated in this sub-clause accidentally contradicts a statement or requirement defined in , the
text of ISO/IEC 14496-1 prevails.
The following sub-clauses specify the normative tests for verifying compliance of IPMP bitstream, IPMP Data
and IPMP Message. Those normative tests make use of test suites and the reference software decoders
specified in ISO/IEC 14496-5:2001/AMD4 (MPEG-4 IPMPX reference software) with source code available in
electronic format.
9.2 Specification of test IPMP bitstreams
9.2.1 Conformance Requirements
IPMP bitstreams shall comply with the specifications in ISO/IEC 14496-1.

ISO/IEC 14496-4:2004/Amd.4:2005(E)
9.2.2 Tolerance
There is no tolerance for IPMP bitstream syntax checking. The diagnosis is pass or fail.
9.2.3 Terminal conformance
Each compliant IPMP terminal shall be able to parse and process all compliant IPMP bitstreams. As the
implementation of IPMP terminals differs from each other depending on the implementers, the bit-wise
comparison of the terminal output with a reference output may not work. The judgment should be done from
the total behavior of the terminal.
9.2.4 Tool conformance
Not applicable.
