Macrovision awarded CD copy protection patent

Macrovision needed probably some good news to lift their stocks and has released news to the press that they have been awarded U.S. Patent #6,353,890 for a method of copy protecting CD content ("Method For Copy Protecting A Record Carrier, Copy Protected Record Carrier And Means For Detecting Access Control Information").

According to Macrovision the patent is essential to the companies future and the company expects other extensions in its usage in the future, on other types of optical media such as DVD


Bill Krepick, president and CEO of Macrovision added, "The SafeDisc patent augments our portfolio of patented copy protection technologies, enabling us to offer critical solutions for the music and software industries. SafeDisc is established as the PC games industry's leading copy protection solution, now being used on approximately 80% of the top U.S. PC games(2).

This patent will further enhance our leading position in that market and in the application software market, as well as give us added strength in our music copy protection business with our recently introduced SafeAuthenticate solution."


I know that some of you will probably say, heck this protection has already been beaten, but note that their protection is pretty good and is not easily copyable by the average home user and that is where copy protections are about.

They are not intended to be unbreakable, every copy protection is, but they try to make it as hard as possible for you to make a pirated copy (and unfortunately also a backup), because the more time you spend on it, the bigger the chance you will give up...

You tell me what audio cd has US Patent #6353,890 on it and before the sun sets that patent will be history. When are these MORONS going to realize that this aprroach is half ass backwards. Every protection scheme for audio cd's that has been boasted by copy protection companies has gone down the crapper. Why is the concept "if it can be heard it can be recorded" a difficult concept to understand. Was it Steve Jobs that said the same thing recently on TV?

Anything that is made can be copied. Whether heard, written or manufactured it's the same scenario. It's the same with ALL security devices, no matter what form they take, they can be broken... these guys can only ever be one step ahead of us all as long as someone has the wits to continue breaking down their utilities and bright ideas. It only takes a short time to do it yet they spend months and months developing it. I wonder what the kids that write these protections think? "This is a waste of bloody time, but hey I'm getting paid for it." Or "When I've written this and been paid I'm gonna make a fortune flogging it to a hacker?. Or "I've finished this - now let's post it's workaround on the net!!!" :4

SeánI know that hardware copy protections do take some time to break, but no matter what type of protection is used in audio, nothing will ever stop headphone - linein. Also, any digital copyprotection, e.g. DRM in WMA, AAC, etc. can usually be rerecorded digitally pm the same PC using Goldwave or anything else that can record from the soundcard Wink Just be sure the Wave recording mixer is enabled and everything else is muted.

-> seanbyrne: Recording from (via) soundcard is NOT a DIGITAL copy - it's an analog -> digital copy = inferior audio puke You have to GRAB IT to get the pure digital copy (the digital audio data goes from CD/DVD-ROM directly to HDD through the bus without any change by D/A converter in the soundcard). :7

If you record a song through the line in on your sound card, it may be analogue, but you can hardly tell the difference, if at all. To me it all sounds the same. But then, I don't have top-of-the-range speakers.

-> Kafoopsy: The top-of-the-range speakers are not needed to recognise a difference between A or D copy. Just the middle class headphones suffice to it. Of course, dogcheap PC speakers or schlocky (and dogcheap too) audio systems are not able to make any differences... :7

i'll say it again & again - stereo cd's is over & old. 16 bit / 44.1 khz sux compared to 24 bit / 96khz. dvd-a has this. 6 channels man! thats the ticket - dvd-a again. cd & cdr in general should be reserved for us to record on similar to the cassette format back in the 70's.

Yes CD audio is 16bit 44.1Khz. If you do a line in copy using a good soundcard I dare you to tell the difference. What IS funny however is that MP3 is a lossy format anyhow so who cares? A line in copy at 192kbit MP3 will probably sound as good as a direct copy if you use a playback source and good soundcard/software. I've done vinyl copies this way. Yes there will be a loss. But for the formats we are converting to it probably wouldn't make a huge impact anyhow. Direct digital copies are still preferable however Smilie
