| Sep 30, 2008 - Macrovision DVD Copy Protection! |
Macrovision Corporation is a globally-operating, U.S.-based company that develops and markets licensing, access control, and secure distribution technologies for electronically delivered creative works. This includes digital media (video, music), web publishing (text, images), and computer software (consumer software, enterprise software, and video games). The name is also sometimes used to refer to certain video copy prevention schemes developed by that company early in its history. Its customers include the majority of the Fortune 500, as well as most major movie studios, record labels, PC video game publishers, ISVs, consumer electronic device manufacturers, and IC manufacturers.
Macrovision Corporation was established in 1983. The 1984 film The Cotton Club was the first video to be encoded with the Macrovision technology when it was released in 1985. By the end of the 1980s, most major Hollywood studios were utilizing the Macrovision technology. The technology was extended to DVD players and other consumer electronic recording and playback devices such as digital cable and satellite set-top boxes, Digital Video Recorders, and Personal Media Players. Macrovision has subsequently introduced products and services for facilitating access control and secure distribution of other forms of digital media, including music, video games, Web text and graphics, and computer software. On December 7, 2007 Macrovision agreed to buy Gemstar-TV Guide in a cash-and-stock deal worth about $2.8 billion. On the April 1, 2008, Macrovision announced that Thoma Cressey Bravo, a private equity firm, completed the acquisition of Macrovision's software business unit for 200 million USD, in order to form a separate entity called Acresso Software.
RipGuard
In February 2005, Macrovision introduced their new RipGuard technology. This is designed to prevent (or reduce) digital DVD copying by altering the format of the DVD content in such a way as to disrupt the ripping software. Macrovision claims that 97% of all current DVD rippers will not be able to copy a DVD with RipGuard technology. Macrovision released RipGuard-MOD v2.4 in May 2007. MOD v2.4 successfully disrupts some of the methods that these programs use to circumvent the copy prevention, thereby slowing down the copying process significantly. In addition, v2.4 also provides for the ability to copy prevent Recordable DVDs, including Dual Layer Recordables. RipGuard also renders the formatted section of DVDs unwatchable on some players. The audio is intact, but the image appears scrambled. This has been confirmed with Toshiba DVD/TV combo model MD20FL1.[citation needed].
The recent proliferation of cheap DVD recorders has presented a major setback to vendors of DVD anti-copying systems, since by linking a DVD player to a DVD recorder via S-video, and disabling the anti-copy system by using an inexpensive Macrovision removal box, excellent quality dubs can be made, which can then be freely copied. Although they no longer have the menu structure of the original DVD release, many users consider that an 'improvement', since in many cases it means that the entire feature, (stripped of all the "extras") can fit uncompressed on a single-layer disc. It also means that the movie can be watched without having to view multiple previews or several seconds of unskippable corporate logos and copyright warnings.
