Macrovision Signs Copy Protection Agreement with Microsoft Home and Retail Division.

SUNNYVALE, Calif.--(ENTERTAINMENT WIRE)--June 2, 1999--

SafeDisc Technology to be Applied to Microsoft's Educational,

Games, and Personal Finance Software PC CD-ROM Titles

Macrovision Corporation (NASDAQ:MVSN) announced today that Microsoft Corporation (NASDAQ: MSFT) has signed a two-year agreement to use Macrovision's SafeDisc(TM) PC CD-ROM copy protection. Under the agreement, Microsoft will use SafeDisc on a wide variety of educational, games, and personal finance software distributed worldwide.

"We were prompted to consider a copy protection solution because of ongoing losses incurred by software distributors from returns on software that is copied using CD-ROM recordable devices," said Bill Smith, product unit manager at Microsoft. "The Home and Retail Division has run SafeDisc through an exhaustive evaluation process and has found that it will be the most effective way to protect those who legally try to sell software from the impacts of software piracy."

The total estimated value of unauthorized copies of PC CD-ROMs in consumer households is estimated at almost $1 billion according to a study sponsored by Macrovision. The study, which was conducted by San Mateo, CA-based Merrill Research & Associates, estimates that based on survey responses, consumers have 30 million unauthorized CD-ROM copies in their inventory, and that over half of these copies would have displaced interactive software purchases.

"The collective engineering capability, worldwide technical support, relationship with replicators who support our other technologies, and substantial financial resources of the Macrovision/C-Dilla partnership uniquely allows us to support Microsoft's Home and Retail Division and its numerous replicators and OEMs worldwide," said Brian Dunn, vice president of computer software copy protection at Macrovision Corporation. "In addition, Microsoft has been of great assistance in enabling us to develop a Windows-compliant SafeDisc solution."

The SafeDisc technology, which is licensed at 28 replicators worldwide, is a software-based solution that does not require any changes to standard PC or CD-ROM hardware. It is comprised of both an authenticating digital signature embedded on the disc, as well as a multilayered encrypted wrapper that secures the CD-ROM content. The digital signature, which cannot be copied by CD recorders, is added to each original disc during the mastering/replication process. When a user inserts an original disc in a CD-ROM drive, the authentication software reads the digital signature, allowing the program to be decrypted and run normally. If an unauthorized copy is loaded, the authentication software will not be able to find the digital signature, and the copy will not run. The technology is licensed directly to interactive software publishers, and to mastering and replication facilities who are able to offer the technology to their software publishing clients.

SafeDisc, a collaboration between Macrovision and C-Dilla, UK Ltd., represents Macrovision's first copy protection product for the interactive software market. Macrovision is best known for its videocassette copy protection technology, which has been applied to over two billion videocassettes over the past decade. C-Dilla is best known for its rights management software for high value-added information and software publishers.
