Published: Nov 30, 2006

American company that develops various copy-protection schemes for audio and video purposes. Is best known to have their copy-protection mechanism for VHS tapes bundled with virtually every sold pre-recorded VHS tape in the world. Also, every DVD player sold in the U.S. has Macrovision copy-protection mechanism built-in which prevents DVDs to be recorded to VHS cassettes without hacking either the DVD player or the VCR. They have recently also developed various audio CD protection mechanisms and record labels have already introduced few commercial audio CDs that have Macrovision's CDDA copy-protection mechanism.
