DeCSS' Continuing Saga
blankmange writes "Newsbytes is carrying
a followup on the DeCSS and 2600's court cases: "The Electronic Frontier Foundation and the First Amendment Project today asked the California Supreme Court to uphold a lower court's decision to permit publication of the source code for DeCSS technology, which circumvents digital copy protection systems." Maybe it's not over yet..."

It is a scary time to be someone like 2600 now.
- what is the definition of simultanagnosia?! I've been meaning to look it up!
The 2600 case was in federal court in New York. They lost the trial, and were also shot down by the federal appeals court.

This is generally one of the situations in which the Supreme Court will step in, that is, if two states rule differently on a federal law, it is up to no one but the Supreme Court to sort it out.
The Supreme Court only accepts a small percentage of the cases they are asked to hear, but then again generally the states follow each other's precident.

try xine and the dvd nav plugin. It works amazingly and I prefer it to my windows dvdplayers. The only dvd It has had problems with was the menus on the futurama disks.
In CA, Bunner was sued under the California Uniform Trade Secrets Act. This is a state law. In NY, defendants Corley et. al. were sued under the DMCA. This is a federal law.
The interesting part will be if and when the final judgements in these two cases are reconciled with one another -- there is a legal principle that says federal law supersedes state law when the two conflict, but I'm not sure it applies here directly (since one law has to do with trade secrets, the other with copyright).
For example:

Jon Johannsen got the code from an unlocked area of a player IIRC.
Trade secret, let out by mistake = no trade secret.
Considering that the reporting organization doesn't know that DeCSS gets around the -playback- control mechanism, not the -copy protection- mechanism(since there isn't one), I'd say we're pretty screwed.
The enemies of Democracy are
From the article:
In addition, the court found that DeCSS is "pure speech" for the purposes of First Amendment protection.
Say what you will about CA, our courts get it! This is from the CA State Appeals Court Ruling.
Fascism starts when the efficiency of the government becomes more important than the rights of the people.
It wasn't reverse-engineered cleanly, though.
Remember that is was obtained by looking through unencrypted code in the Xing player.
The guy who wrote it even admited that an anonymous source led him to the Xing player to look for the one key to break. After that, the rest of the manufacturer keys were cracked with ease.
If it had been a clean room reverse, then they would have more of a leg to stand on.
However, 2 years later, same situation, different judge, different result, here.
Of course, the above involve crypto, and there were still strong export restrictions in the US in effect.
Beyond that, I can't think of any off hand...
How can it be a trade secret if every DVD manufacturer knows it??
...
It's a trade secret of an organization called the "DVD Copy Control Association" - or, the DVDCCA.
They license the trade secret to all of the player manufacturers, and in return, the player manufacturers sign a contract that, among other things, forbids them from building DVD players with unencrypted digital outputs, and requires them to include Macrovision distortion in the analog output signal. The contract also forbids the disclosure of the CSS algorithm.
The result is that, prior to DeCSS, if you wanted to manufacture DVD players, you needed to sign the contract and agree to the terms in order to obtain the necessary technology to decode DVDs.
Now, the CSS algorithm is cracked.
The danger that the industry is facing is this. If CSS is deemed, by the courts, to be a legitimately reverse-engineered trade secret, then the CSS decoding process would enter the public domain. If that were to happen, it would clear the way for the manufacture of DVDs without having to obey the restrictions of the CSS contract.
In other words, it would allow companies to start manufacturing DVD players with such desirable features as no Macrovision, and digital MPEG outputs. But it wouldn't allow all companies to do so
... only those companies that had not signed a contract with the DVDCAA. In other words, the entire current player industry would be shut out -- they would be still required, by their DVDCCA contracts, to install Macrovision, and not offer digital outputs. This would be a disaster for the current crop of player manufacturers.
There's a reason that they are fighting so hard to force CSS into the category of "stolen trade secret" -- by sheer force of will, apparently. If DeCSS were to be ruled a stolen trade secret, then the courts would prevent anyone else from making commercial use of the algorithm.
This would be an incredible win for the movie industry -- they would receive what would be in effect a perpetual patent -- the right to exclude others from employing a process.
Note that they are fighting this battle on different fronts -- the DMCA case is to try and outlaw the dissemination of the algorithm. The Trade Secret case is to try and outlaw the implementation of the algorithm. They are fighting tooth and nail to control not the right to manufacture DVD players, but the right to dictate what features may and may not be included in DVD players.
Based on the same law? I don't think so. The NY case was about DMCA. The CA case is about trade secrets.
