Macrovision announced new technology today that it hopes will stop users from illegally copying DVD movies. The technology is called RipGuard DVD and it's going to make its way into DVDs starting with the new High Definition DVD films later this year.
The idea behind RipGuard is that it plugs the original security hole that was exposed by the DeCSS software back in 1999, which bypassed the CSS encryption program. This allowed even the average consumer to copy a complete DVD to their computer and distribute the DVD on file sharing networks.
"Macrovision RipGuard DVD is designed to dramatically reduce DVD ripping and the resulting supply of illegal P2P content," said Steve Weinstein, executive vice president and general manager of Macrovision's Entertainment Technologies Group.
Macrovision ensures that DVDs featuring the new technology will work on existing DVD players. SOURCE
