2 Why do I care about the DMP? ( Me and Digital Media Project ) Me as End user: I love country music; “Fair use” My home office My car My wife's car My Course on CD: “Video Compression and MPEG Technology Fundamentals” * Never sold to any individual, only to companies

3 Me as End user/1: I don’t care to ’steal’ content. I only want the freedom to enjoy the content I have paid a license to enjoy in the manner in which I want to enjoy it. It should be legal for me: –to view “Boj na Kosovu”/”Battle of Kosovo”, the movie, on my …anything… if I have purchased the DVD. –to listen “Yugoslavia,” the song, on my …anything… if I have purchased the CD.

4 Me as End user/2: So, while I enjoy free movies or free music, IF that is how it was distributed, I don’t mind paying for movies/music/content as long as the license I am buying allows me to enjoy the purchased movie/music/content when and how I want.

5 Me as content owner/1: Restrict regular users (the ones without the knowledge, initiative, or guts to circumvent the DRM) in how they use movies and such. Strategy of making casual users (the vast majority who honestly want to stay within the law, regardless of how poor the law is) pay more, via pay-per-use, time-limited downloads, etc.

6 Me as content owner/2: Certainly DRM is capable of this, despite being incapable of preventing copying by a few determined individuals. What about “Digital Media Project”? –DMP and regular users –DMP and casual users That’s what I am reviewing as of now –Chillout ® the Reference Software [demoed at IBC 2006] –Recommended Practices for End-to-End Conformance

9 Digital Rights Management DRM is commonly touted as the technology that can restore the value of content A definition of DRM (NIST): –DRM is a system of IT components and services along with corresponding law, policies and business models which strive to distribute and control IP and its rights A DRM system is a form of communication management Without standards a communication system reduces the world to a set of non-communicating islands

2006/09/26The Digital Media Project11 The Digital Media Project Launched as Digital Media Manifesto in Jul 2003 Manifesto published in Sep 2003 – Digital Media Project established in Dec 2003 – The basic DMP position –Digital technologies are an asset of mankind –Creators, intermediaries and end-users should all benefit from them –Goal can be achieved through –Standardisation of appropriate protocols between value-chain users and data exchanged

2006/09/26The Digital Media Project12 Implementing the vision A DRM standard must –Satisfy the manifold needs of media value chain players –Allow to continuously inject innovation –Provide interoperability –Help create horizontal markets It is an impossible task to provide a DRM standard for all value chains –They are just too many –Who knows how they will evolve It is doable to provide standards for low-level functions (Primitive Functions) Value chains assembled from primitive functions

2006/09/26The Digital Media Project13 The DMP Interoperable DRM Platform (IDP) DMP develops the IDP Specification as a toolkit The IDP Specification is developed in Phases –IDP-1 for Portable Audio & Video Devices (PAV), April 2005 ( –IDP-2 for Stationary Audio & Video Devices (SAV), February 2006 ( –IDP-3 for Digital Media Value Chains, January 2007 ( IDP includes “Use Cases” and “Value-Chains” –Guide to build value chains assembling IDP tools IDP includes Chillout® the OSS Reference Software released under MPL 1.1

2006/09/26The Digital Media Project15 The Chillout® Reference Software/1 Chillout is (currently) –Provided as a set of Java libraries –Exposed as web services –Organised as Core library: implements the IDP specification Auxiliary library: encapsulates a number of functionalities Utility library: provides common functionalities Applications: contains a set of sample applications Chillout is released under Mozilla Public Licence (MPL) 1.1 Get Chillout from

2006/09/26The Digital Media Project16 The Chillout® Reference Software/2 Chillout can be used to –Set up interoperable value chains for use by independent users –Test conformance of implementations Chillout has been demoed at IBC 2006 Walkthrough –User selects a TV program from an EPG –Licence to watch is provided –TV program is broadcast in clear text and displayed –When user wants to record TV program, new licence is requested to licence server –File with video and licence is made by end-user device –Stored TV program may be encrypted or in clear text depending on the business model Demo proves Chillout flexibility, not business model value

2006/09/26The Digital Media Project18 DMP outlook IDP-2 is a pretty stable and complete specification A few extensions (IDP-3) are still under way Open Source Reference Software (Chillout) under development Innovative interoperable media value chains can now be established using Chillout Practical use of DMP results is within sight DMP governance infrastructure to be developed next –First step is Content Registration Authority and Agencies

20 My take on the DMP This is my reference (for DRM) –There is no universal DRM system, only implementations of DRM systems that satisfy the needs of specific value chain users If I choose some other solution, it has to be better then the DMP offered solution

22 Just in case … … you have no questions Then verify this: 111,111,111 x 111,111,111 = 12,345,678,987,654,321 What is the product if the multiplicand and multiplier are binary numbers?
