Information technology — MPEG extensible middleware (MXM) — Part 2: MXM API
ISO/IEC 23006-2:2011 specifies a set of Application Programming Interfaces (APIs) so that MXM Applications executing on an MXM Device can access the standard multimedia technologies contained in its Middleware as MXM Engines, as specified by ISO/IEC 23006-1. The APIs belong to the following two classes: the MXM Engine APIs, i.e. the collection of the individual MXM Engine APIs providing access to a single MPEG technology (e.g. video coding) or to a group of MPEG technologies where this is convenient; the MXM Orchestrator API, i.e. the API of the special MXM Engine that is capable of creating chains of MXM engines to execute a high-level application call such as Play, as opposed to the typically low-level MXM Engine API calls.

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 23006-2 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 23006 consists of the following parts, under the general title Information technology — MPEG
extensible middleware (MXM):
⎯ Part 1: MXM architecture and technologies
⎯ Part 2: MXM API
⎯ Part 3: MXM reference software
⎯ Part 4: MXM protocols

Introduction
ISO/IEC 23006 is a suite of standards that has been developed for the purpose of enabling the easy design
and implementation of media-handling value chains whose devices interoperate because they are all based
on the same set of technologies accessible from the MXM middleware.
This will enable the development of a global market of
⎯ MXM applications that can run on MXM devices thanks to the existence of a standard MXM application
API,
⎯ MXM devices executing MXM applications thanks to the existence of a standard MXM architecture,
⎯ MXM engines thanks to the existence of standard MXM architecture and standard APIs, and
⎯ innovative business models because of the ease to design and implement media-handling value chains
whose devices interoperate because they are all based on the same set of technologies.

The MXM APIs are specified in the Java and C++ languages, as follows:
a) A high-level description of the interfaces defining the MXM APIs
b) An html format specification of the MXM APIs with a normative value provided as an attachment to this
document
6 Common MXM interfaces and classes
The core part of MXM consists of a number of interfaces and classes which are common to all MXM Engines.
These are:
⎯ MXM: class enabling MXM Applications to obtain instances of MXM Engines. MXM acts as a factory
instantiating those MXM engines listed in the MXM Configuration file when they are required by MXM
Applications.
⎯ MXMEngine: the interface at a highest level of an MXMEngine. Every MXMEngines extend this interface,
defining a method enabling other entities to query the specific name of an MXMEngine.
⎯ MXMObject: the basic interface for most of the MXM classes. An MXMObject is a wrapper of specific
objects that can therefore be exchanged by MXM Engines. It defines the version of MXM and it provides
a number of fundamental methods to know what type of object is indeed an MXMObject wrapping, what is
the class name of the wrapped object, getters and setters method for getting/setting an object from/into
an MXMObject, etc.
⎯ MXMAdapter: a basic class implementing the MXMObject interface which is a wrapper of specific objects
that can therefore be exchanged by MXM Engines. By means of an MXMAdapter it is possible to convert
any object into an MXMObject.
⎯ MXMEngineName: an enumeration listing all possible names (types) of MXMEngines, so that any entity
can unambiguously determine the name of an MXMEngine.
⎯ MXMException: the highest level of exception thrown by MXM. All other exceptions in MXM extends this
abstract class.
⎯ MXMEngineResponse: an enumeration used as a general-purpose return value for a number of methods.
