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.
ISO/IEC 23004-8 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
ISO/IEC 23004 consists of the following parts, under the general title Information technology — Multimedia
Middleware:
⎯ Part 1: Architecture
⎯ Part 2: Multimedia application programming interface API
⎯ Part 3: Component model
⎯ Part 4: Resource and quality management
⎯ Part 5: Component download
⎯ Part 6: Fault management
⎯ Part 7: System integrity management
⎯ Part 8: Reference software

Introduction
ISO/IEC JTC 1/ SC 29 has produced many important International Standards (for example MPEG-1, MPEG-2,
MPEG-4, MPEG-7, and MPEG-21). One of the next steps in this process is the standardization of an
Application Programming Interface (API) for Multimedia Middleware (M3W) allowing application software to
execute multimedia functions with a minimum knowledge of the inner workings of the multimedia middleware
as well as to support a structured way of updating, upgrading and/or extending the multimedia middleware.

Reference software
1 Scope
This part of ISO/IEC 23004 explains the organization of the reference software for ISO/IEC 23004– 1 to 7
(Multimedia Middleware). The electronic attachment to this part of ISO/IEC 23004 provides the source code of
the actual software.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Overview of reference software
This is an informative clause. The reference software is organized into directories according to the different
parts of ISO/IEC 23004. These directories are:
⎯ 1_Architecture: This directory is rather empty. The architecture is reflected by the implementation of the
other parts.
⎯ 2_Multimedia-API: This directory contains the reference implementation of Audio and Video,
Governance and IPMP logical components. The Audio and Video logical components are based on
UHAPI4Linux implementation.
⎯ 3_ComponentModel: This directory contains the implementation of the core framework, services for
remote method invocation (REMI) and services that allow instantiation of services based on a logical
component id (Service Manager). The core framework also contains tools that aid in the development of
M3W Components (IDL compiler).
⎯ 4_ResourceManagement-Framework: This directory contains the implementation of the resource
management framework. This framework can be used to optimize the Quality of Service perceived by the
user in a situation where resources are constrained and often not enough to run all applications and
services at the highest quality level.
© ISO/IEC 2009 – All rights reserved 1
⎯ 5_ComponentDownload-Framework: This directory contains the implementation of the download
framework. A framework that enables a large number of scenarios of controlled download / upload of
components
⎯ 6_FaultManagement-Framework: This directory contains the implementation of the fault management
framework enabling transparent addition of fault tolerance techniques to your software. The
implementation consists of policies for intercepting the creation of services and tools for generating
wrappers (middleman) that contain the fault tolerance techniques.
⎯ 7_IntegrityManagement-Framework: This directory contains the implementation of the integrity
management framework targeted at maintaining and restoring in consistent software configuration on a
device in the period that a device is owned and used by a consumer.

4 Multimedia API
4.1 Introduction
This is an informative clause. This clause gives a brief explanation on the parts that together form the
reference implementation for the Multimedia API of M3W.
4.2 Audio Video
4.2.1 General
The directory contains the current release of the reference implementation for clauses 7(general interfaces), 8
(audio interfaces) and 9 (video interfaces) of ISO/IEC-23004-2 (clause numbers are according to the FDIS
version).
The implementation is based on the UHAPI4Linux implementation that can be found on Sourceforge
(www.sourceforge.net).
4.2.2 Building
For building instructions please look at:
⎯ 2_Multimedia-API\AudioVideo-API(UHAPI)\HOWTO

4.2.3 Functionality
The reference implementation enables you to build a simple television application with features like changing
channels, adjust volume, adjust contrast, adjust contrast, adjust saturation, image overlay, etc.

logical components
4.3 Governance
4.3.1 Introduction
The function of Security Manager is to provide secure interaction between M3W Service and external entities.
This may include the interaction to acquire Service through download mechanism and invoke Service from
remote peer. Security Manager also provides interface for governance/permission checking for accessing
M3W Service and/or platform’s resources.
4.3.2 Implementation
Currently the implementation consists of one executable component with a SecurityManager service that
implements the ISecurityManager interface suite (logical component) and an example client application that
uses this service.
Service and application are build in the following way:
• autoreconf –is
• ./configure –prefix=$HOME/l
