Rovi Corporation
History
Rovi was established under the name of Macrovision Corporation in 1983. The 1984 film The Cotton Club is the first video to be encoded with Macrovision technology when it was released in 1985. In the late 1980s, the major Hollywood studios that use its services. Technology was extended to DVD players and consumer electronic devices for recording and playback, such as digital cable and decoders, digital video recorders, and personal media players. Macrovision subsequently introduced products and services to facilitate access control and secure distribution of other forms of digital media including music, video games, Web text and graphics, and software.
However, with the conquest of Gemstar-TV Guide on 2 May 2008 a cash and stock deal worth about 2.8 billion U.S. dollars, the company began to develop targeting technology for TV and satellite cable satellite industry.
After the notice of intent to acquire Gemstar – TV Guide, Rovi Corporation completed additional transactions to move your business market outside the licensing of software and entertainment technology market. On February 14, 2008, Thoma Cressey Bravo and then Macrovision Corporation announced that an affiliate of TCB has entered into a definitive agreement to acquire Macrovision's Software Business Unit in a cash transaction valued at approximately $ 200 million. The transaction closed on April 1, 2008. The transaction became Macrovision software business unit in the independent software company after the close of the transaction, which includes FLEXnet, InstallShield, AdminStudio family of products. Mark Bishof, Macrovision, the Software Business Unit Executive Vice President and General Manager, will assume the role of CEO of independent software company after the closing of the transaction. The day was completed acquisition, independent company was named Acresso Software.
Macrovision continued to sell other areas of your business is not aligned with its focus on digital entertainment technology, including Trymedia, emetic, TV Guide magazine, TV Guide Network and TVG – Horse Racing.
On April 29, 2008, Macrovision Solutions Corporation and the Corporation agreed to sell $ 100,000,000 Macrovision aggregate principal amount of its 11% Notes due 2013 JP Morgan Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated for approximately $ 96,500,000. As part of the plan began on December 12, 2007, Mars Merger Sub, Inc., merged with and into Macrovision Macrovision Corporation surviving as a society, Galaxy Merger Sub, Inc., and merged with Gemstar-TV Guide International, Inc., Gemstar-TV Guide as the surviving corporation resulting Macrovision and Gemstar-TV Guide to become a wholly owned subsidiary of Macrovision Solutions Corporation. The operations were closed beyond May 2, 2008. Effective May 5, 2008, the shares of each of Macrovision Corporation and Gemstar-TV Guide would cease to be traded and no longer is quoted in the Nasdaq Global Select Market. The remaining shares are trading Macrovision Solutions Common Exchange under the symbol "MVSND" until June 2, 2008, which traded under the symbol "MVSN" later. The resulting company was called Macrovision Solutions Corporation.
The company announced its intention to acquire All Media Guide of November 6, 2007 and substantially all the assets of Muze, Inc. on April 15, 2009. Both companies provide entertainment metadata.
On July 16, 2009, Macrovision Solution Corporation announced the official change of name to Rovi Corporation.

Content Networking Technology
Rovi technology portfolio includes a networked software content to store, search and play back personal content-based Internet. Connect technology is a technology standards-based software for home electronics devices.
Content Protection
RipGuard
In February 2005, Macrovision introduced its RipGuard technology designed to prevent or reduce the digital DVD copy of modifying the contents of the DVD format to interrupt ripping software. Although the technology can be avoided by several current DVD rippers such as AnyDVD and DVDFab, Macrovision says that 95% of casual users lack of knowledge and / or determination to be able to copy a DVD with RipGuard technology.
Analog copy protection
NTSC and other formats video store and transmit analog video signals as a series of Agnes. Most of these lines (483 for NTSC) are used for the construction of the visible image, and displayed on the screen. But there are several more (43 in NTSC) which are not displayed on the screen. Known as the vertical blanking interval (VBI), these lines are used to express additional different things in different countries, including subtitle.
legacy of Macrovision analogue copy protection (ACP) works with the implementation a series of over-voltage pulses in the VBI lines off-screen video. These impulses are included physically within existing recordings on VHS, and generated in the reproduction of a chip in the DVD and digital cable / satellite boxes. A DVD recorder that receive an analog signal with these pulses the detect and display a message saying that the source is "copy-protected, followed by abort the recording. Video players, in turn, will react to these over-voltage pulses through the compensation circuit with automatic gain control, causing the recorded image to change violently brightness, making it impossible to see.
In most televisions, these pulses do not cause visible effects because their circuits automatic gain control, unlike AGC circuits in VCRs, is purposely designed not to react to them. TV very old, however, react to them, producing distorted images as a result. In some TVs that do not fall into white vertical refresh, with points also white lines at the top of the image. Some TVs newer error also Macrovision pulses for synchronization pulses.
Another form of Macrovision analog copy protection, the "level ACP II, had multiple 180 degree phase reversals for the analog signal is colorburst. Also known as colorstriping, this technology led to numerous racy bands appear in the image. A later version, Level III ACP, simply added more investment phase, bringing the number of stripes visible on the screen.
Another form of analog copy protection, known as CGMS-A, is added for DVD players and digital cable / satellite boxes. Although not invented by Macrovision, the company's products implement it. CGMS-A consists of a "flag" in the vertical blanking interval (Essentially data such as subtitles) looking for digital recording devices. If present, refuse to register the signal, as with the previous ACP technology. Unlike digital recording equipment, however, analog VCRs do not respond to CGMS-A encoded video and burns it whether non-ACP is also present.
Historically, the original Macrovision technology was considered a nuisance for some specialist users, as could interfere with other electronic equipment. For example, if one were to run their video signal through a VCR before the television, some players Video would be a sign of doom, whether it is recording. This also occurs in some sets of TV-VCR combo. Apart from this, many DVD recorders confuse the mechanical instability of the tapes used for the Macrovision signals, and thus refuse to realize what it would be perfectly legal DVD movies dubbing old people's home and the like. This widespread problem is another factor contributing to the demand for devices that defeat Macrovision. The signal has also been known to confuse the line doublers home theater (devices to improve the quality of video for large projection TVs) and some TV filters high-end comb. In addition, Macrovision confuses many converters (devices that convert a video signal to a higher resolution), switching it off and refuse to play content from Macrovision.
Some DVD players give the user the option to disable the Macrovision technology. This is possible because the signal not stored on the DVD itself, instead commercial DVDs contain an instruction to the player to create this type of signal during playback. Some DVD players can be configured to ignore such instructions.
There are also devices called stabilizers, stabilizers or enhancers available video filter Macrovision spikes and thereby defeat the system. The principle of its function is to detect the vertical sync signal, and forcing the lines occurring during the vertical blanking interval of black level, the elimination of the pulses of AGC-confusing. They can be easily built by amateurs, as nothing an inexpensive microcontroller together with an analog multiplexer and other small circuit is needed. People with less experience with these things can be bought stabilizers Internet video. The best device to defeat Macrovision is a time base corrector (TBC), although more expensive than simple video stabilizers.
The discs with DVD copying software like DVD Shrink automatically disable any Macrovision copy protection. USB based video interfaces designed to allow burning DVDs on personal computers are required by law to detect the presence of any Macrovision analog input signals to them, and if so, to prevent burning.
The MPAA claims that he has every right to restrict the copying of movies, DVDs compared to pay-per-view where the consumer is allowed to see the film in question, but nothing more. Many are concerned that the organization is trying to override the fair use by not allow consumers to make personal copies.
On the other hand the ease with which Macrovision and other copy protection measures can be defeated has led to a number increasing the DVD releases that have no copy protection whatsoever, CSS or Macrovision.
Kingdom States law of fair use, as interpreted in the the Betamax decision (Sony Corp. v. Universal City Studios), dictates that consumers are fully in your legal right to copy videos of their property. But the legality has changed somewhat with the controversial Digital Millennium Copyright Act after April 26, 2002, no VCR can be manufactured or imported without circuits AGC (Which makes them vulnerable to Macrovision VCRs). This information is contained in Title 17, Section 1201 (k) of the Digital Millennium Copyright Act, however, a number of models oldest of its majority in the VCR market that is not affected by Macrovision.
On October 26, 2001, sale, purchase or manufacture any device not have commercial purpose other than disabling Macrovision copy protection was made illegal under section 1201 (a) of the controversial act the same.
In June 2005, Macrovision sent a letter of cease and desist from "Lightning UK", the maker of DVD Decrypter, a program that allows users to backup their DVD without going through the CSS and Macrovision. Later acquired the rights to this software.
In June 2005, Macrovision sued Sima Products under section 1201 of the DMCA, claiming that Sima's video processors provide a way to circumvent the Macrovision analog copy protection. Sima received a restraining order the sale of this device, but ultimately, the parties settle without a trial on legal issues.
