History Macrovision Corporation was established in 1983. The 1984 film "The Cotton Club" was the first videocassette 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 when they were first launched in 1997. The Cotton Club is a movie, released in 1984, centered around a popular real-life Harlem jazz club in the 1930s, the Cotton Club. ...

Macrovision for video A VHS videotape or DVD (no laserdisc or video CD players implement it) or digital cable/satellite boxes receiving a data stream encoded with Macrovision will cause a VCR set to record it to fail (excluding very old models, modified VCRs, or those approved for "professional usage"). This is usually visible as a scrambled picture as if the tracking were incorrect, or the picture will fade between overly light and dark. A 6-head or 8-head VCR (most are 4-head) can minimize this fluctuation, so it is not as noticeable. A DVD recorder will simply display a message saying the source is "copy-protected", and will pause the recording.

This is achieved through a signal implanted within the offscreen range (vertical blanking interval) of the video signal—either physically recorded directly on the tape (as with VHS) or created on playback by a chip in the player (as with DVDs) or the digital cable/satellite box (as with all HDTV programs being down-converted to standard definition). The vertical blanking interval (VBI) is an interval in a television or VDU signal that temporarily suspends transmission of the signal for the electron gun to move back up to the first line of the television screen to trace the next screen field. ...

NTSC and other video formats store the video signal as “lines.” A portion of these lines are used for constructing the visible image by transposing them on the screen, but there are approximately 20 to 40 lines outside the visible range that are used for different things in different countries, like closed captioning. The references in this article would be clearer with a different and/or consistent style of citation, footnoting or external linking. ...

Macrovision inserts pulses into this non-displayed area. These signals cause the automatic gain control on the recording VCR to compensate for the varying strength. This makes the recorded picture wildly change brightness, rendering it unwatchable. On most televisions, the viewer on the screen sees no effect in ordinary playback of the modified video because the signal is outside the visible area, but some TVs do not properly blank the vertical retrace and leave dotted white lines near the top of the picture. Some newer TVs also mistake the Macrovision pulses for synchronization pulses. Automatic gain control (AGC) is an electronic system found in many types of devices. ...

Another modification also used in Macrovision is the addition of colorstripes—rapidly modulated colorburst signals.
Technical problems Macrovision is considered a nuisance to specialist users because it may interfere with other electronic equipment. If one were to run their video signal through a VCR before the television, some VCRs will output a ruined signal regardless of whether it is recording. This also occurs in some TV-VCR combo sets.
Apart from this, many DVD recorders mistake the mechanical instability of worn videotapes for Macrovision signals, and so refuse to make what would be perfectly legal DVD dubs of people's home old movies and the like. This widespread problem provides a legitimate basis for the sale of devices that defeat Macrovision.
The signal has also been known to confuse home theater line doublers (devices for improving the quality of video for large projection TVs) and some high-end television comb filters. In addition, Macrovision confuses many upconverters (devices that convert a video signal to a higher resolution), causing them to shut down and refuse to play Macrovision content. A line doubler is a device used to de-interlace video signals prior to display. ...
In signal processing, a comb filter adds a delayed version of a signal to itself, causing constructive and destructive interference. ...
Legal issues Some DVD players give the user the option of disabling the Macrovision technology. This is possible since the signal is not stored on the DVD itself; instead commercial DVDs contain an instruction to the player to create such a signal during playback. Some DVD players can be configured to ignore such instructions.
There are also devices called stabilizers, video stabilizers or enhancers available that filter out the Macrovision spikes and thereby defeat the system. The principle of their function lies in detecting the vertical synchronization signal, and forcing the lines occurring during the vertical blanking interval to black level, removing the AGC-confusing pulses. They can be easily built by hobbyists, as nothing more than a cheap microcontroller together with an analog multiplexer and a little other circuitry is needed. Individuals less experienced with such things can purchase video stabilizers off the internet from companies. The best device for defeating Macrovision is a Time Base Corrector (TBC), although they are more expensive than the simpler video stabilizers. The vertical blanking interval (VBI) is an interval in a television or VDU signal that temporarily suspends transmission of the signal for the electron gun to move back up to the first line of the television screen to trace the next screen field. ...

Discs made with DVD copying programs such as DVD Shrink automatically disable any Macrovision protection. USB-based video interfaces designed to allow DVD recording on PCs are legally required to detect the presence of Macrovision signals on any analog signals input to them, and if so, inhibit the recording, but few, if any, do so. DVD Shrink is a freeware program for Microsoft Windows that facilitates backing up DVD movies. ...
The MPAA maintains it has every right to limit copying of movies, comparing DVDs to pay-per-view where the consumer is allowed to view the movie in question but nothing more. Many are concerned that the organization is attempting to quash fair use by disallowing consumers to make personal copies. The Motion Picture Association of America (MPAA) is a non-profit trade association formed to advance the interests of movie studios. ...

On the other hand the ease with which Macrovision and other copy-prevention measures can be defeated has prompted a steadily growing number of DVD releases that do not have protection of any kind, CSS or Macrovision. Content Scramble System (CSS) is a Digital Rights Management (DRM) scheme used on almost all commercially produced DVD-Video discs. ...
United States fair use law, as interpreted in the decision over Betamax (Sony Corp. v. Universal City Studios), dictates that consumers are fully within their legal rights to copy videos they own. However, the legality has changed somewhat with the controversial Digital Millennium Copyright Act. After April 26, 2002, no VCR may be manufactured or imported without Automatic Gain Control circuitry (which renders VCRs vulnerable to Macrovision). This is contained in title 17, section 1201(k) of the Digital Millennium Copyright Act. However, there are a number of mostly older VCR models on the market that are not affected by Macrovision.

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 protected by RipGuard technology. However, it can be bypassed with Slysoft's AnyDVD, Fengtao's DVDFab Decrypter, RipIt4Me, or MacTheRipper 3 for Mac OS X.

As of May 2007, RipGuard-MOD v2.4 has been released which has plugged many of the exploits that the above named rip programs used to circumvent the protection. In addition, v2.4 also provides for the ability to copy protect 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 a cheap Macrovision removal box (which many owners already have), 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-sided disc. It also means that the movie can be watched without having to view multiple previews or sit through several seconds of unskippable corporate logos. This is an example of the pitfalls of anti-counterfeiting measures, that make the counterfeit perceived as being more valuable than the original. For other uses, see Counterfeit (disambiguation). ...
Cactus Data Shield - Main article: Cactus Data Shield
Cactus Data Shield (CDS) is a form of copy control for audio compact discs developed by Midbar Tech, now owned by Macrovision. There are several types, commonly described as CDS100, CDS200 and CDS300. However, there are about seven subtly different versions of CDS200. CDS200 discs are usually labeled as 'copy controlled' (CCCD). (They are officially not designated CDs). CDS300 discs are labeled as 'content protected'. CDS300 discs cannot be ripped by iTunes in particular. However, they contain copies of the music in low bit-rate WMA format, which can be burned to a CD no more than three times.
