Open Media Commons Releases Specifications and Source Code for Open, 
Royalty-Free Digital Rights Management

Workshop, Hosted by Sun, Draws Industry Representatives from Around the World

SANTA CLARA, Calif.\u2014March 21, 2006\u2014Sun Microsystems hosted the first 
Open Media Commons (OMC) Workshop last week to further the community's goal of 
developing open, royalty-free digital rights management (DRM) and codec 
standards. In conjunction with the workshop and building on the announcement 
last year of Sun Labs' Project DReaM (DRM/everywhere available), Sun released 
two draft specifications for content protection technologies \u2013 DReaM-CAS 
(Conditional Access System) and DReaM-MMI (Mother May I). Sun also released 
open source code for a prototype implementation of the DReaM-CAS conditional 
access system. More than 80 participants from a range of organizations came 
together to discuss new technical specifications and source code, define plans 
for the completion of those specifications and determine the next steps 
required to develop an open, royalty-free DRM solution.

The DReaM-CAS client specification defines a complete open conditional access 
system that enables delivery and consumption of protected content over Internet 
Protocol (IP) networks, using the MPEG-2 Transport Stream (TS) format. The CAS 
model utilizes open standard technologies for security such as PKI and SSL, as 
well as existing content protection technologies such as AES, ECC and 3DES. In 
addition, Sun posted the open source code for a prototype implementation of the 
DReaM-CAS conditional access system at https://dream.dev.java.net.

The DReaM-MMI specification outlines a different approach to managing rights 
for a variety of client types that are directly or indirectly connected to 
content networks. The design philosophy underlying DReaM-MMI is that clients 
should be able to negotiate for rights through standardized protocols rather 
than downloading a license with an embedded expression of rights. The 
specification defines the message protocol, message transport and a list of 
profiles required to ascertain rights by a DRM client from a rights server.

These specific technical measures for content protection form the core of 
securing and safeguarding content in any DRM solution. DReaM, based on a 
service oriented architecture system design that leverages open standards, is 
capable of interoperating directly with other content protection technologies 
and supports services that enable both Conditional Access System and Digital 
Rights Management models. The specifications are initially available under the 
OMC terms at http://www.openmediacommons.org, and Sun ultimately plans to 
release the implementation code as open source under the OSI-approved Common 
Development and Distribution License (CDDL).

\u201cWith more people and devices participating on the network every day, 
there is a growing need for the community to develop and implement an open, 
safe and business-friendly DRM solution,\u201d said Tom Jacobs, project lead 
for Open Media Commons and a director in Sun Microsystems Laboratories. 
\u201cWe're encouraged that participants from across the DRM value chain, from 
content creators, owners and distributors, to consumer electronics device 
manufacturers and industry organizations, are coming together to address the 
issues and propose viable solutions.\u201d
Organizations represented at the workshop include technology companies such as 
Cisco, HP and IBM; consumer electronics device manufactures such as Motorola, 
Panasonic and Samsung; content distributors such as Sony BMG and Warner Music 
Group; network operators such as Telecom Italia; and industry organizations 
such as MPEG-LA. More information from the workshop, including speaker 
presentations, transcripts and technical documentation, is expected to be 
available shortly at.

Supporting Quotes From Workshop Keynote Speakers

Lawrence Lessig, Chairman of the Board of Directors of Creative Commons and 
Professor of Law at Stanford Law School: "In a world where DRM has become 
ubiquitous, we need to ensure that the ecology for creativity is bolstered, not 
stifled, by technology. We applaud Sun's efforts to rally the community around 
the development of open-source, royalty-free DRM standards that support 
\u201cfair use\u201d and that don't block the development of Creative Commons 

Richard Pietravalle of The MITRE Corporation: "The technology surrounding 
digital rights management has widespread application in the enterprise and the 
public sector to improve information sharing, while affording additional 
protection for sensitive materials and records. Open, interoperable digital 
rights management standards can help increase the availability of digital 
rights management-based solutions for the secure sharing of sensitive 

Mariellen Calter of Stanford University Libraries & Academic Information 
Resources: "Universities would benefit from open, standards-based DRM 
technology that would allow students and faculty to easily access, use and 
share copyrighted information in a fair manner. I'm interested in the work of 
the Open Media Commons to develop open-source, interoperable DRM standards that 
address the needs of learning institutions."

About the Open Media Commons
Sun's Open Media Commons is an open-source community project to develop 
royalty-free codecs and digital rights management (DRM) solutions. The goals of 
the OMC are to develop an open-source, royalty-free solution for the 
distribution of digital content, focused on authenticating people and roles, 
not just devices; to address the application of DRM technology to a wide range 
of content and situations, including personal rights management, the privacy of 
health records and compliance management for businesses dealing with 
Sarbanes-Oxley; and to create an open environment where creators, content 
owners, consumers, network operators, technology providers and consumer 
electronics device manufacturers can work together to address the technical 
problems associated with DRM.
