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?

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

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.

• Server:– MXM-based Java

server

• 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
