10、ation. 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 mutu
11、al 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 accordan
12、ce 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 Standa

15、Information technology Coding of audio-visual objects 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 1449
16、6-1. 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 bitstre
17、am 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
18、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
19、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 compli
20、ance 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.
21、2.1 Conformance Requirements IPMP bitstreams shall comply with the specifications in ISO/IEC 14496-1.

22、sis 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 referenc

The judgment should be done from the total behavior of the terminal. 9.2.4 Tool conformance Not applicable. 9.2.5 Test IPMP Bitstream 9.2.5.1 #IPMPBS1 BitStream: MPEG-4 system stream with IOD, BIFS, OD stream, one H.263 visual stream, and one G.723.1 audio stream and IPMP info
