Macrovision Wants Old DRM to Work Forever

Grv writes "Macrovision's best-known form of copy protection inserts noise into analog video signals to make it difficult to get a good copy of the DVD or VHS recording. A company named Sima has products that eliminate this noise when digitizing such video, as any good digitizer would do. Macrovision argues that this is a violation of the DMCA, and a court sided with them in June. Now the injunction is being reviewed, and several organizations are siding with Sima and Fair Use, including the American Library Association, the Consumer Electronics Association, the Home Recording Rights Coalition, and the Electronic Frontier Foundation. If it isn't overturned, this decision could make it illegal to develop products for making copies of commercial analog recordings."

    I am shocked that people still care about "rights" (sic) abuses on analogue material, the only reason you would be doing this is because you had bought a copy a long while ago and now want to be able to enjoy that copy on a system you have. Do they even make VHS? new piracy would be stupid from this angle. Besides cracking it in digital format is far easier...

    They are just trying to screw you over again and again and again. Fortunately I don't live in a country with the DMCA or equivalent, but I sympathise, I hate getting screwed over by companies and the government when their working against the people.

Defy away; however, a more reasonable and responsible citizen might suggest that if a law is believed to be unjust, they have a duty to try and get it overturned through legal and ethical means first.

    This is just a drop in the bucket. I'm curios to see if I'll live to see it publicly recognized, that having a law, writing that ownership on an idea exists, is fundamentally wrong. The problem is so elemental that many people will have to die before this thruth comes forcefully to light, just like it was with communism.

    With so much outsourcing for the actual work, with services so expensive, America more than anyone is dependent on the cash flow from copyright. To make matters worse, the society is based on greed and the only stopper to that is competition, twisted so much as it turned into distributed greed, helped to prosper by the law. Even if a spiritual revolution should come tommorow, and looking at who is the elected president there are no worries for that, the enterprise demons created by this society won't just dissapear without a fight. And that is natural.

    A thick, well established and powerfull layer of people fight over your bodies as you stand and watch your politically correct shows day in and day out. How can this perfect 1984 society claim to honour freedom as it's founding fathers did, when freedom was lost a long time ago? How will you be able to kill the sick system that already exists when all you know is TV and TV dinners? How can you justify yourselves the fact that your copyright laws caused millions on this planet to die in horrible sufferings because medicine developments are stalled when you need dozens of patents to even start research on anything?

    I'll humbly suggest the first step: Literally throw away your TV and start caring about each other. Stop buying crap, stop buying movies from Hollywood and start getting your music by going to concerts played by your local artists. Maybe then, your children will have a fighting chance and the rest of the world won't have to enter in the third war against a once great nation.

    if the mysterious "HQ" technology that suddenly started appearing on all the VCRs had anything to do with Macrovision or copy protection? I have always suspected this, as, by my recollection, HQ appeared around the time this copy protection arrived. All that whining about putting a special "tax" on blank tapes went away around the same time as well. It all makes me wonder if the "HQ" (that allegedly gave you a "20% better picture") wasn't actually the enabler for copy protection. This could help explain why TVs didn't have a problem with copy protected content, but VCRs did. I thought maybe someone in /. land might have some first hand knowledge about HQ and could shed some light on this.

    Well, if you have an ATI TV Wonder card, you can simply modify a value in the source code that will eliminate Macrovision "interference". I do this on my home system so that I can watch my DVDs and Video Tapes on my 17" monitor. I don't have a lot of room where I live, and I sold my TV a while ago.

  12. The copyright clause in the Constitution... by karl.auerbach · · Score: 3, Interesting

    The copyright clause in the Constitution allows Congress to enact laws to protect the work of authors only for limited periods of time.

    Now, in the Mickey Mouse case, the court said that protection periods on the order of 100 years are OK, but the Court kinda hinted that it might not go along with this much further.

    Anyway, the technique of leveraging DRM protections in via a copyright and then having them live forever is rather a slap in the face of the Constitutional limitation on the duration of copyrights.

    Of course, Congress does have a weasel-way out: they might say, "oh, we allow DRM to exist forever as part of our powers over commerce among the states."

    But in practical terms, DRM forever transforms what is supposed to be a copyright of limited duration into a copyright that lasts for all eternity. And that, is contrary to the purpose, a purpose actually stated in the US Constitution, to promote the arts and sciences, for copyright and patents.

    See my note "The Rule Against Digital Perpetuities". It's short, so I'll just copy it here:

    The Rule Against Digital Perpetuities

    It seems to me that in the fight over copyright and digital rights management few have considered what happens in the distant future when the material being protected is no longer covered by copyright. That thought led me to propose the following rule and accompanying pledge.

    The Rule Against Digital Perpuities:

            No Digital Rights Management (DRM) limitation or anti-copying mechanism may endure longer than the original copyright in the protected work.

    The Pledge:

            I pledge to neither specify nor standardize nor implement any system that does not conform to the Rule Against Digital Perpetuities.

      Thats a helpful codification. But I have a question. I have thought to myself before "I pledge to QUIT MY JOB before I make a DRM product." But then I make activation keys and so forth... the activation key will work forever and doesnt require online validation. A thousand years from now the key will work. Am I violating this rule by producing copyrighted software which is still protected in a thousand years? Or am I following it by resisting an online activation which might break (if my company founders) and thus render the software absolutely inoperative beyond the duration of copyright. Am I supposed to put a check in the code: if(!isValid && date 1/1/3000) forbid()? I look at it this way: once we give out the combination of software and activation key, we have no control over what they do with it. So our control of the users into the future extends for zero duration and so certainly not beyond the copyright.

    A better solution is to make a really really good digital copy. I thought the idea was that your TV could display the signal with macrovision noise added, but your VCR would lose sync and get all garbled because it was unable to make a good copy of the "noise". If you make as perfect a copy as you can, wouldn't you be able to play it back? It may still violate copyright, but you wouldn't be circumventing anything - the macrovision would be intact.

    1. Re:A better solution by ajs318 · · Score: 5, Interesting

      It's just crap in the vertical retrace interval. The VCR doesn't lose sync, but since the noise exceeds the normal signal level it causes the AGC to reduce the gain, thereby making the picture go dim. If you did not know any better, then you might suppose it to be a mere artefact from the mass-production process {since it is conspicuously absent from home recordings}. If you shorten the AGC time constant on the recording VCR {by unsoldering one capacitor} you won't get the dimming effect. You can also use an op-amp hard limiter circuit {similar to those cheesy guitar distortion pedals everyone was building in the 1980s} to clamp the spikes.

      A more thorough way of defeating Macrovision is to use a 1881 sync separator, 4066 quad bilateral switch and some assorted logic ICs {or a microcontroller}. You need to discard about 30 lines from the top of each field, clamping them to no more than 0V but pulling them down to -0.3V with the line sync pulses. If you can manage to leave in the colour subcarrier burst, then so much the better.

      As long as you're making fair use of material, which you have an inalienable right to do, then the use of an electronic circuit to remove this copy protection would be classified as Reasonable Force in pursuit of your Statutory Rights.

How are the courts going to "protect" macrovision without making time-base correctors illegal?
