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 1 to ISO/IEC 13818-4:2004 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 1: MPEG-2 IPMP conformance testing
Add the following clauses at the end of Audio section:
2.6 Conformance for MPEG-2 IPMP
2.6.1 Introduction
In this document, the additional text to ISO/IEC 13818-4:2004 is specified for the conformance test of ISO/IEC
13818-1:2000/Amd.2 & 13818-11 MPEG-2 IPMP. In this clause, except where stated otherwise, the following
terms are used for practical purposes:
The term ‘content stream' or ‘system stream’ means ISO/IEC 13818-1:2000 system bitstream possibly with
multiplexed ISO/IEC 13818-2:2000 visual streams and ISO/IEC 13818-3:1998 audio streams.
The term ‘IPMP bitstream’ means an MPEG-2 system stream with information of IPMP protection, including
IPMP Descriptor, IPMP Stream, IPMP Tool List.
The term ‘IPMP Information’ means “IPMP Control Information” in PSI, “IPMP Descriptor” in PMT, and IPMP
Stream that come from 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-2 terminal with IPMP Extension capability as specified in 13818-
1:2000/Amd.2 & 13818-11 MPEG-2 IPMP.
If any statement stated in this sub-clause accidentally contradicts a statement or requirement defined in
13818-1:2000/Amd.2 & 13818-11 MPEG-2 IPMP, the text of 13818-1:2000/Amd.2 & 13818-11 MPEG-2 IPMP
prevails.
The following subclauses 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 13818-5:2002/Amd.4 with source code available in electronic format.

2.6.2 Specification of test IPMP bitstreams
2.6.2.1 Conformance Requirements
IPMP information contained in PSI of MPEG-2 system stream shall comply with the specifications in 5 and 6
of ISO/IEC 13818-1:2000/Amd.2 & ISO/IEC 13818-11 (MPEG-2 IPMP).
2.6.2.2 Tolerance
There is no tolerance for IPMP Bitstream syntax checking. The diagnosis is pass or fail.
2.6.2.3 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.
2.6.2.4 Tool conformance
Not applicable.
2.6.2.5 Test IPMP Bitstream
2.6.2.5.1 #IPMPBS1
BitStream: MPEG-2 TS stream with PAT, PMT, one MPEG-2 visual stream, and one MPEG-1 Layer 2 audio
stream and IPMP information.
Specification: The IPMP information includes:
� Tool List in PSI: containing one IPMP Tool ID.
� IPMP Descriptor in PMT. Specifying one IPMP Tool therein is to be loaded before MPEG-2
video decoder (control point is set before decode buffer).
Purpose:
� Verify that the IPMP terminal handles IPMP Tool List, makes sure the required tool is present.
� Verify that the IPMP terminal handles IPMP Descriptor, and launches the IPMP Tool according
to information given in the IPMP Descriptor.
2.6.2.5.2 #IPMPBS2
BitStream: MPEG-2 TS stream with PAT, PMT, one MPEG-2 visual stream, and one MPEG-1 Layer 2 audio
stream and IPMP information.
Specification: The IPMP information includes:
� Tool List: containing two IPMP Tool IDs.
� Two IPMP Descriptors in PMT: the IPMP Tools specified therein are to be loaded before
MPEG-2 video render and before MPEG-1 Layer 2 audio decoder, respectively. (The control
point is set accordingly).
Purpose:
� Verify that the IPMP terminal handles IPMP Tool List, makes sure the required tools are present.
� Verify that the IPMP terminal handles IPMP Descriptors, and launches the specified IPMP Tools
according to information given in the IPMP Descriptors.
