Limelight Networks & Widevine Provide Content Delivery & Multiplatform, Multiformat DRM for Flash, Other Media Formats

Widevine’s mature, studio-approved DRM solution enables secure delivery for all premium content

TEMPE, AZ. and SEATTLE, March 31, 2008 — Limelight Networks (Nasdaq: LLNW), and Widevine Technologies, the only provider of a multiformat and multiplatform digital rights management solution, today announced that the companies have integrated Widevine Cypher® with Limelight Networks' high-performance content delivery architecture. The alliance will enable media and entertainment companies to monetize virtually every piece of content in their libraries by securely delivering a high-quality rich-media experience to any platform, browser or operating system.

This alliance enhances the value of Limelight’s fully-optimized network for Flash delivery and Widevine’s unique ability to provide a ubiquitous “Switzerland of DRM” solution which supports Adobe Interactive Runtime (AIR) for downloads, Flash Media Server and other HTTP servers for progressive downloads. Limelight customers choosing the solution will no longer have to deal with managing multiple DRM systems to support users with different video formats on different devices as Widevine is compatible with all browsers, including Internet Explorer, Firefox and Safari as well as all operating systems, including Windows, Macintosh and Linux.

“We’re pleased to welcome Widevine into the Limelight Networks partner ecosystem. Widevine offers one of the most robust and interoperable rights management solutions available today. When combined with Limelight’s highly scalable architecture and open APIs, our customers can now choose a complete and compelling system for securely delivering high-value premium content to consumers,” said David Hatfield, senior vice president of products, marketing and sales at Limelight Networks, Inc.

The technology alliance also seeks to provide higher ad-supported revenues to content owners by preserving the integrity of the content offering. Secure Flash streams and HTTP downloads can be verified and tracked by Widevine’s DRM, thereby enabling advertisers to send more targeted ads to consumers along with verification that the content has been accessed and viewed. In addition, Widevine has amassed a significant intellectual property portfolio for video security on the Internet.

“Widevine’s alliance with Limelight provides the digital media industry the seamless, ubiquitous, and secure distribution of premium content they have requested,” said Brian Baker, CEO of Widevine Technologies. “Content owners, aggregators and distributors now can securely monetize assets delivered to consumers regardless of device or computing platform with a single content security solution from Widevine in parallel with the leader in content delivery.”

Widevine‘s integration with Limelight includes post-decryption digital copy protection to detect, monitor and respond to the hundreds of screen scraping and recording utilities available on the Internet. Many of these utilities can record and store a stream as a downloadable file that can easily be edited to strip out valuable online ad inventory and be uploaded onto a file sharing network, depriving content owners of revenues.
