Overview

ISO/IEC 14496-5:2001/Amd 4:2004 is Amendment 4 to Part 5 (Reference software) of the MPEG‑4 family. It adds the IPMPX (IPMP eXtensions) reference software extensions that implement the MPEG‑4 IPMP (Intellectual Property Management and Protection) Extension specifications referenced in ISO/IEC 14496‑1 and ISO/IEC 14496‑13. The amendment supplies source directories, tools, test files and an informative guide to the reference implementation based on the IM1 player framework.

Key topics and technical highlights

  • Reference software components: New directories under IM1 such as IM1/IPMP-H (IPMP Hooks) and IM1/IPMP-X (IPMPX extensions) with subcomponents:
    • IPMP tools: IPMP_DESTool, IPMP_DummyTool, IPMP_MasterTool, IPMP_RELTool, IPMPXFull
    • Libraries: BinaryMessagesLib, Lib
    • Test files and example license/query XML files, DES DLL and keys for DES-based test scenarios
  • Architecture & runtime model: Documented components include IM1 Terminal, Message Router (MR), IPMP Tool Manager (TM) and IPMP Tools. The amendment describes the control flows such as tool instantiation, message routing, IPMP stream setup and ES handling.
  • Interface examples (informative, non‑normative): Function signatures shown in the reference software (examples):
    • Terminal APIs: GoNoGo(), SetFilter(), ReleaseFilter()
    • Message Router APIs: ProcessIPMPDescriptor(), ReceiveMessage(), SetUpIPMPStream()
    • Tool Manager APIs: ConnectTool(), DisconnectTool(), ReceiveToolES(), Init_AvailableIPMPTools()
    • IPMP Tool APIs: ReceiveMessage(), ProcessMessage(), ProcessData()
  • Distribution & build guidance: Source retrieval via the MPEG CVS path "MPEG‑4/System2" (case sensitive), WinCVS checkout instructions and compile/readme guidance under IM1/Docs/_ReadmeFirst.doc.

Practical applications and users

  • Who uses it: Implementers of MPEG‑4 players, digital rights management (DRM) engineers, IPMP tool developers, system integrators and researchers working on protected audio‑visual content.
  • Why it’s useful:
    • Provides a tested, reference implementation of IPMPX messaging and tool lifecycle for prototyping and interoperability testing.
    • Supplies example tools, test streams and license scenarios to validate IPMP workflows (tool ES, DES examples, XML license files).
    • Clarifies non‑normative interface patterns for integrating IPMP tools with media players.

Related standards

  • ISO/IEC 14496‑1 (Systems / Base MPEG‑4)
  • ISO/IEC 14496‑13 (IPMP Extensions)
  • Part 5 (Reference software) core standard: ISO/IEC 14496‑5

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 14496-5:2001 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia

Guidance of IPMP software
C.1 Introduction
C.1.1 How to get the codes
This annex identifies, describes and explains the provided reference software that implements the MPEG-4
IPMP Extension specifications found in ISO/IEC 14496-1 and ISO/IEC 14496-13.
The reference software, which is based on IM1, includes all the normative parts of the MPEG-4 IPMP
Extension standard, and some informative part as well. The reference software can be retrieved from MPEG
CVS server under path "MPEG-4/System2".
C.1.2 How to compile
To retrieve the reference software from MPEG CVS server, open WinCVS, click on the parent directory of
MPEG-4/ directory. Then, go to menu Remote/Checkout Module and in the Checkout settings dialog, under
"Module name and path on the server", enter MPEG-4/System2 (warning: this is case sensitive!).
Please go to MPEG-4/Systems2/IM1/Docs/ and read _ReadmeFirst.doc which is necessary for you compile
IM1. Follow all the steps, one after another. This will help you configure your machine correctly, download
whatever missing software required by players in order to compile BifsEnc, Mp4Enc, Im1Player, IM1-2D,
Osmose, Player3D with MPEG-J support.
As for IPMP-X portion, a simple user notes document can be found in IPMP-X directory under IM1 directory
to provide the initial guidance.
C.1.3 Source codes directory
Please follow the user notes document under IPMP-X directory when you operate on the source codes.
IM1/IPMP-H contains most of IPMP Hooks related files, including the following three sub-directories.
• /IPMPNull
• /IPMP
• /Lib
