TTR is a developer of optical media-based copy protection technologies for the software and music industries. Macrovision's investment in TTR is part of the two companies' joint efforts to develop and market a copy protection system that will inhibit back-to-back unauthorized copying of Music CDs using dual-deck CD recorder systems and personal computer based CD-Recordable drives.

The two companies have agreed to pool their respective technologies and related patents for Music CD and DVD Audio copy protection. Macrovision will be responsible for licensing the technology to music rights owners on a worldwide exclusive basis. The two companies intend to work cooperatively with encoder manufacturers and CD replicators to implement the manufacturing and quality control systems necessary to commercialize the jointly developed Music CD copy protection technology.

An additional aspect of the agreement grants Macrovision an exclusive license to TTR's CD and DVD signature technology and related encoder modules that are used to embed signatures during the replication process. Digital signatures are a critical element of both Macrovision's and TTR's computer software copy protection systems.

Macrovision intends to use this technology to enhance its existing software copy protection technologies which it currently markets under the SafeDisc and SafeCast brands. TTR and Macrovision intend to work cooperatively to transition existing software customers of TTR's DiscGuard(TM) technology to Macrovision's SafeDisc(TM) or SafeCast(TM) technologies early in the year 2000.

"We're pleased to have become an investor in TTR and look forward to working with TTR as our music copy protection partner," stated John Ryan, chairman and CEO of Macrovision.

"We look forward to working closely with Macrovision to develop a best of breed copy protection technology for the music industry," added Marc Tokayer, chairman and CEO of TTR. "CD-Recorders which retail for less than $150 and which are capable of copying Music CDs onto blank CD-R discs costing less than $1.00 create the need for effective copy protection solutions."

Macrovision is best known for its video copy protection technologies that are used by Hollywood studios and other rights owners worldwide to deter unauthorized VCR copying of prerecorded videocassettes, DVDs, and digital cable/satellite pay-per-view programs, and for its SafeDisc software copy protection technology which is used by Microsoft, Electronic Arts, and other software companies worldwide to deter unauthorized copying of CD-ROM based consumer multimedia and entertainment software.

Macrovision has also introduced its SafeCast suite of copyright management technologies that supports secure software downloads over the Internet.
