...Paramount Home Entertainment has agreed to license Macrovision’s content protection products, ACP and RipGuard. ACP and RipGuard provide protection against unauthorized copying of content across packaged media such as DVD as well as electronic channels such as the Internet, cable and DBS.
The license also grants Paramount the right to use Macrovision’s advanced Blu-ray protection technology, BD+. Along with the other technologies, Macrovision’s BD+ provides an additional content protection method for content released on Blu-ray. The Blu-ray format provides consumers with high definition video, a more interactive user experience via BD-Java, and exciting new features available in the most recent Blu-ray players with BD-Live.
Thus far, Fox is the only studio known to be using BD+. The relationship between Macrovision and the BD+ licensing authority, BD+ Technologies, LLC, remains opaque.
