 Content-scrambling system - Wikipedia, the free encyclopedia
Content Scramble System (CSS) is an encryption system used on some DVDs.
The CSS algorithm was soon revealed to be easily susceptible to a brute force attack.
CSS key is a collective term for authentication key, disc key, player key, title key, second disk key set, and/or encrypted key.

 NewsFromRussia.Com Content Scramble System will stop pirates DVD coping
That technology called the Advanced Access Content System, which is not designed for today's DVDs, is being designed to let movies be moved around a home though a digital network.
Macrovision Corp. said its RipGuard system, which can be included in personal computers, DVD players and DVD recorders, would plug the digital hole through which unauthorized versions of DVD films can be easily copied on a computer and then "burned" to other discs or put online for downloading More details...

 Blu-ray makes unexpected, three-way DRM choice for high-def DVD TG Daily
One of the perceived failures of first-generation DVD was that its encryption mechanism of choice, called Content Scramble System (CSS), was spectacularly defeated, with the result being that the industry was forced to permanently and irreversibly support a now-worthless encryption scheme.
One part of the announcement that had been anticipated by experts was Blu-ray's embrace of Advanced Access Content System (AACS), one version of which has also been adopted by the HD DVD Forum.
BD+ appears to be Blu-ray's version of a concept previously under consideration called SPDC, which enabled the method for encrypting a disc's contents to be included on the disc, rather than on the EPROMs of the disc player.

 Europe4DRM, Offline DRM, Copy Protection
While DVD regional coding is a comparatively primitive protection system, the benefit it provided has encouraged film producers and manufacturers to continue to work closely together on copy protection, which has resulted in a standard protection system for DVDs, called Content Scramble System (CSS), developed by the DVD Copy Control Association.
One of the earliest protection systems to be widely used on digital media was DVD regional coding.
The system relies on a coding recognition system built into DVD players, which are sold on a regional basis.

 DVD Copy Control Association v. McLaughlin, et al. Complaint
DVD CCA is the sole licensor of a proprietary system for the encryption and decryption of data contained on DVDs known as the Content Scramble System (or "CSS").
Without motion picture content, there would be no viable market for computer DVD drives and DVD players, as well as the related computer chips and software necessary to run these devices.
Without the motion picture companies' copyrighted content for DVD video, there would be no viable market for computer DVD drives and DVD players, as well as the related computer chips and software necessary to run these devices and, thus, there would be no DVD video industry.

 Kaleidescape > News & Reviews > Legal Updates
On December 7th, 2004 the DVD Copy Control Association (“DVD CCA”) filed a breach of contract suit against Kaleidescape which alleged that Kaleidescape was in breach of its license from the DVD CCA for the Content Scramble System (“CSS”).
For one, Kaleidescape spent a number of years developing its system to comply with the DVD CCA’s complex legal and technical requirements – Kaleidescape has even filed a patent application on its method for complying with the DVD CCA’s requirements.
end-users are allowed to make a personal copy in the Kaleidescape system of a DVD movie they have purchased, so long as they don’t then sell or otherwise transfer that particular DVD movie without deleting it from the Kaleidescape system.

B.J.F. 524 (1989), on which Corley relies, are inapposite, as those cases involve content-based laws aimed at speech.

 Norwegian Authorities Charge Teen DVD Software Author
DeCSS is a computer program designed to defeat an encryption-based copy protection system known as the Content Scramble System, or CSS, which is employed to encrypt and protect the copyrighted motion pictures contained on digital versatile discs, or DVDs.
The Norwegian Economic Crime Unit (OKOKRIM) on Wednesday charged Jon Johansen, 18, with crimes linked to his creation of DeCSS software when he was only 15, according to the Electronic Frontier Foundation (EFF).

 PCWorld.com - Defendant Acquitted in DVD Hacking Case
Johansen created a program in 1999, called DeCSS (also known as De Contents Scramble System), to crack the CSS (or Content Scrambling System) copy protection on DVDs, and made the code available to others on the Internet.
Johansen's distribution of the code on the Internet was also considered in depth by the court, and it found that "this program could be useful for both legal and illegal purposes, like many other devices," Manshaus said.
Jon Lech Johansen, also known as DVD Jon, has been acquitted in Oslo City Court of charges over his development and distribution of DeCSS, a program that can be used to break the digital copy-protection mechanism of DVDs, his attorney said Tuesday.

The settlement resulted in an agreement by Cheertek to abide by the Content Scramble System (CSS) license agreement, a security measure that protects DVDs from illegal reproduction.
The MPAA has been on the warpath trying to ensure next-generation audio/video technologies incorporate sufficient content protection.
Within the last sixteen months, the major motion picture studios have obtained five court-ordered injunctions against major DVD chip manufacturers that breached the CSS license, making copyrighted material vulnerable to piracy.

DeCSS was the name given to decrypted Content Scramble System, or CSS.
Corley's attorneys had argued at trial that publishing the program, called DeCSS, was protected as free speech and their client was merely covering the news value of the technological development by posting the code.
She said she had not seen the appeals court ruling, but was disappointed upon learning of the outcome.

 Consensus at Lawyerpoint: MPAA FAQ on Broadcast Flag
MPAA answer: Yes, because Satellite and cable services use a proprietary conditional access system to scramble all of their program channels, including retransmissions of digital terrestrial TV broadcasts, they may be obligated, through private rebroadcast contracts, to trigger the same protection from unauthorized redistribution for content as designated, or not, by the flag.
MPAA answer: The Broadcast Flag was created by the Advanced Television Systems Committee (ATSC), which is the standards-setting organization that developed the technical specifications for digital television in the U.S. EFF comment: The broadcast flag was created by Fox, and subsequently ratified by ATSC as an optional part of ATSC's standards.
MPAA answer: The broadcast flag will be successfully implemented once the suppliers of computer and electronics systems that receive broadcast television signals incorporate the technical requirements of the flag into their products.

 DVD Copy Control Association v. Andrew Bunner - Phillips Nizer LLP Internet Library of Law and Court Decisions
DeCSS permits a user to evade the "content scramble system" which both encrypts DVDs and is designed to prevent their unauthorized use and duplication.
DeCSS consists of computer source code which permits the playing of an encrypted DVD on a non-CSS equipped DVD player or drive.
DeCSS does not fall into any of these established exceptions: it is not lewd, profane, obscene or libelous, nor did it involve any fighting words.

 September/October 2001
Corley, who publishes 2600, a Long Island-based hacker magazine and Web site, is a defendant in a lawsuit brought by the motion picture industry that seeks to prevent the distribution of DeCSS (as in De-Content Scramble System), a program that strips the encryption that prevents DVDs from being copied.
Corley's attorneys took the case to the Second Circuit Court of Appeals, where a ruling could come at any time.
In August 2000, Kaplan made the temporary injunction he had issued in January permanent, and further barred Corley from even linking to the sites, many of which were hosted on overseas servers out of the reach of U.S. courts.

 GigaLaw.com: Is Hyperlinking Legally at Risk?
Corley had published on his site a program known as DeCSS, which enabled users to circumvent CSS -- the "Content Scramble System" built into DVD players that prevents copying.
To listen to the losing defendants and their supporters in a recent case involving a software tool that facilitates the copying of DVDs, you'd think that a judge in New York had declared that hyperlinking is illegal.
True, Federal District Judge Lewis A. Kaplan certainly ruled against Eric Corley and 2600 Enterprises, Inc., publisher of the magazine "2600: The Hacker Quarterly" and the web site known as 2600.com.

The objection was not that the program, DeCSS (Decryption Content Scramble System), was copyrighted, because it wasn't.
The 2600 community is the kind of fruit forever borne and boasted by open societies.
In response to accusations that they promote and facilitate illicit behavior, 2600 points to the line separating that which is illegal from discussions of that which is illegal.

Because no one can be an expert on everything, designers have always had to scramble to find the information and know-how required to make a design work until now.
Whether a marketing campaign or a museum exhibit, a video game or a complex control system, the design we see is the culmination of many concepts and practices brought together from a variety of disciplines.
The organization of the book follows it's own principles, the content is specific and accurate, and it cites and gives credit where due (also promoting deeper study of a subject/concept).

 USATODAY.com - Calif. State Supreme Court weighs free speech
The DVD Copy Control Association, an arm of Hollywood studios, sued, saying the association, not Bunner or others, controls the program called the content scramble system, or CSS, which prevents unauthorized copying of a movie sold in the DVD format.
But the 6th District Court of Appeal in San Jose lifted that injunction, a move the DVD Copy Control Association said was akin to giving crooks the technology to reproduce protected material — such as movies — en masse.
The association urged Norwegian authorities to charge him with stealing trade secrets, and he was acquitted in January.

 0105: DVD CCA is an Innovation-Stifling Cartel - CE-Pro.com
The DVD CCA was created in 1999 to be the sole licensor of the Content Scramble System (CSS), an encoding scheme used by DVD makers to thwart the playback of DVDs by anything other than a "legitimate" DVD player.
I don’t know enough to suggest that the DVD CCA is wrong in the Kaleidescape case.
Contrary to popular theory, the DVD CCA is not necessarily a mouthpiece for Hollywood.

 EFF: EFF Prepared Testimony at Copyright Office section 1201 rule-making hearings- Public domain motion pictures released on CSS-protected DVDs
EFF has sought a narrow exemption for audiovisual works and movies that are in the public domain in the United States, and that are released solely on DVD format, where access to the content is prevented by Contents Scramble System, and possibly other technological protection measures.
Even if section 1201 applies to a DVD compilation which includes public domain and copyrighted parts, the requested exemption will permit circumvention only for the purpose of accessing and copying public domain works within the compilation.
This claim is based on two misunderstandings: first, about the merged nature of CSS as both an access and copy control, as recognized by Judge Kaplan in the Corley case and the Register and the Librarian of Congress in the 2000 Final Rule.
