Macrovision launches licensing program for worldwide patent family covering passive music CD technologies


The VeriTOC family of patents covers "shift key-immune" protection, authentication, fingerprinting and selective enablement of music CDs

Macrovision launched a comprehensive licensing program for its VeriTOC worldwide patent family for music CDs. The VeriTOC family is comprised of 23 worldwide patents, many obtained from and developed after Macrovision`s acquisitions of MidBar Tech (1998) Ltd. and TTR Technologies, Ltd.

The term "passive" refers to the fact that these technologies are embedded in the optical media, and do not involve installed software on an end-user`s PC to produce their desired effect.

Licensing the VeriTOC worldwide patent family allows content owners, independent software vendors, content-protection providers and optical media manufacturers to (1) offer music CD fingerprinting; original-disc authentication; personal computer "shift key-immune" music content protection; and secure pass-through access to original CD content, and (2) embed these technologies onto the optical media of music CDs. Macrovision believes that comprehensive licensing of its VeriTOC worldwide patent family will accelerate adoption and development of these music CD technologies.

Macrovision`s market-leading CDS-300 CD content protection product employs technologies derived from patents found in the VeriTOC family, which have been applied to over 450 million commercially released CDs.

For more information, or to inquire about obtaining a license, please visit the Macrovision VeriTOC webpage www.macrovision.com/products/veritoc/index.shtml .
