The DVD Copy Control Association (DVD CCA) is an organization primarily responsible for the copy protection of Blu-ray Discs and DVDs. The Content Scramble System (CSS) was devised for this purpose to make copyright infringement difficult, but also presents obstacles to some legitimate uses of the media. The association is also responsible for the controversial Regional Playback Control (RPC), the region encoding scheme which gives movie studios geographic control over DVD distribution.
As of 2001, members included film distributors such as Metro-Goldwyn-Mayer, Twentieth Century Fox and Warner Bros.
They filed the much publicized case versus Jon Johansen whom they alleged wrote DeCSS. The case was dropped in January 2004. CSS decrypting software (such as DVD Decrypter, AnyDVD, and DVD Shrink DVD Copy) allows a region-specific DVD to be copied as an all-region DVD. It also removes Macrovision, Content Scrambling System (CSS), region codes, and user operation prohibitions. Additionally, they also filed a suit DVD CCA v. Bunner against people who distributed DeCSS, seeking injunction to stop further distribution based on trade secret claims. The injunction was eventually denied because CSS was no longer a secret by the time litigation occurred.

Famous quotes containing the words copy, control and/or association:
“I learn immediately from any speaker how much he has already lived, through the poverty or the splendor of his speech. Life lies behind us as the quarry from whence we get tiles and copestones for the masonry of today. This is the way to learn grammar. Colleges and books only copy the language which the field and the work-yard made.”
—Ralph Waldo Emerson (1803–1882)
“We as a nation need to be reeducated about the necessary and sufficient conditions for making human beings human. We need to be reeducated not as parents—but as workers, neighbors, and friends; and as members of the organizations, committees, boards—and, especially, the informal networks that control our social institutions and thereby determine the conditions of life for our families and their children.”
—Urie Bronfenbrenner (b. 1917)
“An association of men who will not quarrel with one another is a thing which has never yet existed, from the greatest confederacy of nations down to a town meeting or a vestry.”
—Thomas Jefferson (1743–1826)
