MPEG-21 – Multimedia Framework
Leonardo Chiariglione – Telecom Italia Lab
IP networking and MEDIACOM-2004 Workshop
Geneva, CH – 01/04/24
Slide: 2
MPEG - the beginnings
The rationale Digital technologies destroy industry boundaries Digital audio and video standards should be developed as
generic technologies
The advantage of generic technologies They can be used by multiple industries They can be used to provide interoperability across
industries
Communication standards are about interoperability!
Slide: 3
The achievements
MPEG-1 Approved Nov 1992 - Error free environments
MPEG-2 Approved Nov 1994 - Broadcast TV and package media
MPEG-4 Approved Oct 1998 and Dec 1999 - Object based AV coding
MPEG-7 To be approved Jul 2001 - Multimedia description
MPEG-21 First standard approved Mar 2002 – Multimedia framework
Slide: 4
MPEG-1 - ISO/IEC 11172:1992
Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s Part 1 - MPEG-1 Systems - Program Stream Part 2 - MPEG-1 Video for CD –I Part 3 - MPEG-1 Audio Part 4 – Conformance Part 5 – Reference software
Slide: 5
The use of MPEG-1
Video CD (>60 million players sold in China)
“The” format of audio and video for PC (MPEG-1 software decoders in Windows)
MPEG-1 Audio layer III (a.k.a. MP3) is widely used for Web music (more than 100 million software players)
Digital Audio Broadcasting (DAB) utilises MPEG-1 Audio layer II
Several types of MPEG-1 video cameras on sale
Slide: 6
MPEG-2 - ISO/IEC 13818:1994
Generic coding of moving pictures and associated audio Part -1 Systems - joint with ITU Part -2 Video - joint with ITU Part -3 Audio Part -4 Conformance Part -5 Reference software Part -6 DSM CC Part -7 AAC - Advanced Audio Coding Part -9 RTI - Real Time Interface
Slide: 7
The use of MPEG-2
Over 50 million set top boxes for satellite/cable sold
Digital television VHF/UHF broadcasting
Over 30 million hardware DVD players sold
Several tens of million software DVD players sold
The MPEG-2 4:2:2 profile is largely used in the television production industry
MPEG-2 has created the entirely new digital television industry worth ~30 billion USD
Slide: 8
MPEG-4 - ISO/IEC 14496:1998
Coding of audio-visual objects Part 1 Systems Part 2 Visual Part 3 Audio Part 4 Conformance Part 5 Reference Software Part 6 DMIF - Delivery Multimedia Integration Framework Part 7 Optimized Software Part 8 4 on IP Part 9 Reference Hardware Description
Slide: 9
The use of MPEG-4
MPEG-4 Video adopted for visual communication in the mobile
environment used in WMF Being requested by customers for all low bitrate
applications Huge open source movement
MP4 file format adopted for visual communication in the mobile
environment
Slide: 10
MPEG-7 – ISO/IEC 15938
Multimedia content description interface Part 1 Systems Part 2 DDL - Description definition language Part 3 Visual Part 4 Audio Part 5 Multimedia description schemes Part 6 Reference software Part 7 Conformance testing
Slide: 11
Role of MPEG standards – past and future The past
MPEG technologies have been used to create infrastructures on which business can flourish
This happened in the simple transposition of the physical/analogue world to the digital world
The future MP3, DviX and peer-to-peer protocols etc. have shown
the power of digital content in people’s hands These technologies have resulted in mass abuse of other
people’s IPR because of the absence of an appropriate infrastructure
Slide: 12
MPEG-21 – The vision
A future where every human on the Earth is potentially an element of a network involving billions of content providers billions of value adders billions of packagers billions of service providers billions of consumers billions of resellers
To make this future real we need an infrastructure enabling electronic commerce of digital content
Slide: 13
Is MPEG trying to tame the hackers? MPEG technologies have been used to innovate
substantially the way people produce, offer, access and consume digital content
But MPEG has a also long history in working with the creative industries and rights holders’ communities on the identification, management and protection of intellectual property carried on systems designed to MPEG specifications.
Slide: 14
MPEG-21 - Method of work
Define a framework supporting the vision statement
Involve relevant bodies in this effort
Identify the critical technologies of the framework
Understand how the components of the framework are related and identify where gaps exist
For each of the non-available technologies If they fall under the MPEG expertise then develop them Else engage other bodies to achieve their development
Perform the actual integration of the technologies
Slide: 15
The basic elements of the framework What
A Digital Item is a structured digital object with a standard representation, identification and metadata within the MPEG-21 framework.
Who A User is any entity that interacts in the MPEG-21
environment or makes use of a Digital Item.
User A User BTransaction/Use/Relationship
Digital ItemAuthorization/Value Exchange
Slide: 16
Example of Digital Item “music compilation” music
photos
video
animation graphics
lyrics
scores
MIDI files
interview with the singers
news related to the song
statement by an opinion maker
rating of an agency
position in the hit list
navigational information driven by user preferences
bargains
...

Slide: 18
The MPEG-21 technologies - 1
1. Digital Item Declarationa uniform and flexible abstraction and interoperable schema for declaring digital items
2. Digital Item Identification and Descriptiona framework for identification and description of any entity regardless of its nature, type or granularity
3. Content management and usageinterfaces and protocols to enable creation, manipulation, storage, delivery and (re)use of content across the content distribution and consumption value network
Slide: 19
The MPEG-21 technologies - 2
4. Intellectual Property Management and ProtectionThe means to enable content to be persistently and reliably managed and protected across networks and devices
5. Content representationDigital representation of content as different media so that content can be moved and consumed seamlessly
6. Terminals and networksThe means to provide interoperable and transparent access to content across networks and terminal installations
Slide: 20

MPEG-21 – Where we are - 1
PDTR of “Vision, Technologies and Strategy” FDTR approval: July 2001
WD of “Intellectual Property Management and Protection” FDIS approval: Mar 2002
WD of “Digital Item Declaration” FDIS approval: Mar 2002
WD of “Digital Item Identification and Description” FDIS approval: Jul 2002
Slide: 23
MPEG-21 – Where we are - 2
Call for Requirements on “Rights Data Dictionary and Rights Description Language” Deadline for responses: 1 Jun 2001
Other Calls will be produced as requirements on other areas mature
Slide: 24
From the Call for Requirements Standard ways of expressing information about
intellectual property rights in the machine-to-machine network environment Usage permissions expressed by producers and publishers
down the delivery and value chain (‘downstream rights’). Define and manage the rights of creators and their
relationship with producers and publishers (‘upstream rights’)
Rights management solutions must look beyond individual media sectors to cover the IP industries as a whole
