Macrovision® Launches Comprehensive Patent Licensing Program for Current and Next-Generation Optical Media Formats Used In PCs, Media Centers, Game Consoles and Digital Appliances

LONDON. - March 8, 2005 - Macrovision^® Corporation (Nasdaq: MVSN), the world's leading supplier of content and software value management solutions, today launched a comprehensive licensing program for its VeriBIT^TM worldwide patent family covering solutions embedded onto current and next-generation optical discs used to deliver software and multimedia content to PCs, media centers, game consoles, and network-connected digital appliances. The VeriBIT family is comprised of over 30 worldwide patent assets, many obtained from and developed since Macrovision's acquisitions of C'Dilla, Ltd., TTR Technologies, Ltd., and MidBar Tech (1998) Ltd.

The VeriBIT worldwide patent licensing program enables software/game publishers and developers, content owners, independent software vendors, PC and CE manufacturers (including consoles and digital appliances), content-protection providers and optical media manufacturers to:

(1) Offer optical disc-based digital signature generation; original-disc authentication; data payload protection using obfuscation and application fading; secure pass-through access to data on the disc; and secure, authenticated disc-to-Internet web linking;

(2) Embed these technologies onto a range of optical media including CDs, DVDs (including today's high-definition DVDs), and next-generation optical media formats; and,

(3) Use these technologies to securely deliver software, games, and standard and high-definition multimedia content to PCs, media centers, game consoles and network-connected digital appliances (e.g. satellite-based navigation systems).

Macrovision believes that comprehensive licensing of its VeriBIT worldwide patent family will accelerate adoption and development of these technologies for use among this complete range of current and next-generation optical media.

Macrovision's market-leading SafeDisc^® Advanced copy and hack protection product is based on patents found in the VeriBIT family, and is used on over 70% of the world's top game titles and over 300 million CDs, DVDs and high-definition DVDs.

"Macrovision has developed and introduced several commercially successful optical-media based content protection and rights management solutions to the interactive software market since 2000," said Rob Ellison, product marketing director at Macrovision's Entertainment Technologies Group. "We are very pleased to offer our VeriBIT intellectual property portfolio as a comprehensive licensing program to give our publisher customers, as well as their manufacturing and distribution partners, more flexible choices in the marketplace and enable them to address new content usage models with current and next-generation optical media."

VeriBIT joins VeriTOC^TM, Macrovision's recently announced patent family covering passive music CD technologies, as a second key strategic intellectual property licensing initiative to accelerate technology adoption spanning a broader content value management ecosystem comprised of packaged media, online distribution and hardware devices.
