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: 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

Page 12: Slide: 1 MPEG-21 – Multimedia Framework Leonardo Chiariglione – Telecom Italia Lab IP networking and MEDIACOM-2004 Workshop Geneva, CH – 01/04/24.

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

Page 13: Slide: 1 MPEG-21 – Multimedia Framework Leonardo Chiariglione – Telecom Italia Lab IP networking and MEDIACOM-2004 Workshop Geneva, CH – 01/04/24.

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

Page 15: Slide: 1 MPEG-21 – Multimedia Framework Leonardo Chiariglione – Telecom Italia Lab IP networking and MEDIACOM-2004 Workshop Geneva, CH – 01/04/24.

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

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

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

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

Page 24: Slide: 1 MPEG-21 – Multimedia Framework Leonardo Chiariglione – Telecom Italia Lab IP networking and MEDIACOM-2004 Workshop Geneva, CH – 01/04/24.

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
