What if …
• … one does not need to have in-depth knowledge of specific MPEG technologies / standards?
• … one is able to start with application/business development as soon as some (reference) software becomes available?
• … one is able to exchange applications’ underlying (reference) software with optimized one at no cost?

Outline
• Vision
• Overview
• Architecture
• Application Programming Interface (API)
• Example Instantiations
– Fully Interoperable Streaming

The MXM Vision
• MPEG-21 Multimedia Framework
• From Framework to Platform respecting– Creator and rights holders rights to exploit their works– End user wish to fully enjoy the benefits of digital
media – Various value-chain player interest to provide
products and services
➪ DMP has specified Interoperable DRM Platform (IDP)2009/11/23-24 Christian Timmerer, Klagenfurt University, Austria 5

The MXM Vision (cont’d)
• From Platform to Middleware enabling– APIs + protocols in a platform-independent way + …
(see the following slides)➪ MPEG Extensible Middleware (MXM)
What’s next?• From Middleware to Terminal enabling
– ITU-T: definition of IPTV infrastructure and components
– MPEG: development of enabling technologies for, e.g., IPTV

Overview
• A set of APIs to access possibly all MPEG technologies
• Simple methods to call complex functionalities inside MXM engines
• “Thin” applications because the complexity is in the MXM engines
• Replacement of MXM engines with better performing ones at no cost
• Creation of a global market of MXM Engines, MXM Applications and MXM Devices

Overview (cont’d)
The MXM standard – ISO/IEC 23006 – is subdivided in four parts:• Part 1 - MXM Architecture and Technologies specifies the MXM
architecture and references the technologies that are part of an MXM implementation;
• Part 2 - MXM Application Programming Interfaces (APIs): specifies the MXM APIs;
• Part 3 - MXM Conformance and Reference Software: specifies conformance tests and the software implementation of the standard
• Part 4 – MXM Protocols: specifies a set of protocols enabling distributed applications to exchange information related to content items and parts thereof, including rights and protection information

Motivation of providing API
• MPEG specifications: huge amount of technology– 157 standards in ISO/IEC 14496 (MPEG-4) family
– 43 standards in ISO/IEC 15938 (MPEG-7) family
– 33 standards in ISO/IEC 21000 (MPEG-21) family
– …
• Around 11 000 pages, 1,5 m high when printed
• However, majority of people developing MPEG related applications do not need to know that is inside the boxes, but only how to use it

The MXM Approach
3. Documenting the IN/OUT points in another …MPEG standard: 23006-2 MXM API
- only 37 pages , - around 500 methods
1. Creating wrapping libraries, called engines
2. Opening the engines at ESSENTIAL points only

MXM APIs of Each Engine have been Divided into…
• Creation e.g. – Encode a raw audio track– Create an MPEG-7 metadata description
• Access e.g. – Get data from a Digital Item– Decode a video
• Editing e.g. – Add an elementary stream to a multiplexed content
• Engine-specific e.g. – RELEngine: authorise(license, query)– LicenseProtocolEngine:
requestLicense(licenseID, serviceURL)

Fully Interoperable Streaming ofMedia Resources in Heterogeneous Environments
2009/11/23-24 Christian Timmerer, Klagenfurt University, Austria 18
Including MPEG-4 3D graphics in 3rd-Party Application
• Including mp3, jpeg, mp4 video in third party applications is nowadays a beginner job. – The complexity of such codecs is hidden behind a very simple communication
interface once the content is decoded: matrix of pixels for images and wave samples for audio.
• Transposing the same principle in Computer Graphics world is a challenge due to the variety of representation forms and also the complexity and heterogeneity of data to be transferred
2009/11/23-24 Christian Timmerer, Klagenfurt University, Austria 19
By using the MXM 3DGraphicsEngine and its set of APIs, the complex integration work is simplified.
With only some lines of code, Ogre3D, a very well known 3D graphics rendering engine, is transformed into an MPEG-4 3D graphics player.

• Protocols:– MXM Protocols over
SOAP and XMPP
Join the MXM Development Team!
• Why you should join
– Plenty of interesting work still has to be done
– Enough space for student projects, master thesis, PhD thesis, etc.
– You can choose between Java, C++ or start a new implementation in another language!
– It gives you visibility on a broad set of MPEG technologies
– Web site, blog, reflector, and soon more utilities
– Friendly and collaborative environment
