    you are correct sir.

  3. Not even close on Another Audio Watermark Scheme Wins TI DSP Contest · · Score: 3, Informative

    Lets be clear here....... these watermarks are in the AUDIO - not in the specific digial representation. They are designed to survive thru generation loss, going from digital->analog->digital again (and maybe going form CD -> MP3 encoding back to CD) or any of a thousand variations.

    If i make a recording that is a voice saying "DO NOT DUPLICATE" and every recording device on the market 'listens' for that sound, and if it hears it refused to record, the fact that you play via analog an re-record won't matter. The only way around it would be to remove the "DO NOT DUPLICATE". Now what these schemes do is exactly that - except they do lots of complicated and tricky ways to hide "DO NOT DUPLICATE", along with trying to encode it in the most robust fashion even if the signal gets modified. And in the same vein, they try to hide the signal in such a way that removing it would cause too much undesireable in the underlying music. The Stanford guys that broke the SDMI challege showed that it was possible to remove, but removing it ISN'T simple.

    In your above 'cracking' example, it would only work if your recording device (not the microphones, the actual machine that persisted the music coming in) didn't respect/obey the watermark.

    You haven't cracked anything. You've only demonstrated that you haven't a clue on how this technology works, nor a simple basic understanding of signal processing theory. If you ask Santa nicely he might bring you a spectrum analyzer for chrismas.....

  4. Re:Already Cracked! on Another Audio Watermark Scheme Wins TI DSP Contest · · Score: 2

    nope.

    First - digital audio contains VERY little frequencies that can't be heard by humans - what would be the point of encoding audio that can't be heard? For dogs? c.f. Nyquist sampling limit. Compact discs are sampled at 45Khz, so 22.5Khz is the upper limit of the sound that they can repro. That is outside of human range, but not by much.

    Second - generally these watermarking schemes are very sophisticated. A simple band limiting/passing filter isn't going to do it. You need to do know the specifics of how it's encoded to remove it.... not that it can't be done (c.f. the guys that broke the SDMI challenge). Watermarks contain 'echo's' of themselves, time dependant bits, time independant bits, using one sound to mask another (a human wouldn't hear it), etc etc etc. They're pretty sophisticated.

    About 4 years (?) ago at MIT i saw a demonstration of a watermarking scheme where they played music out of some speakers. They held a microphone up to the speaker, and their computer spit out what the watermark was. So the people who keep saying that they'd re-record watermarked audio this way can only do it if they have a recording device that doesn't obey/enforce the watermark. The fact that they've gone Digital->Analog and possibly back to digial doesn't matter a single bit.

    actually i'm not. Other than Antz/Shrek from PDI (which have their own in house renderer), i'd say 95% (conservative estimate) of the feature quality CGI put out is done with PRMan.

    Mental ray - yeah i'd been used for a few things (e.g. Flubber) when you absolutely HAVE to use raytracing. But other than that, no way. It can't swallow the type of scenes that PRMan can handle, the memory requirements are FAR too high, and it's motion blur is weak at best in comparision. There have been plenty of post houses that have tried to use it, but once you start to throw large scenes at it that require quality anti-aliasing, motion blur, and HUGE geometry databases it just falls apart. MR3.0 will tackle *some* of these problems, but the fact that it's a raytracer gives it some inherent limitations of what it can handle.

    And this isn't from somebody who hates mental ray --- i worked on it at Softimage for 3+ years. It's a good renderer, but it's no PRMan.

    'real' rendering is not raytracing. Raytracing is one type of approach for simulation light propagation. It's not the end-all and be-all. it has it's own serious problems.

    Go see a movie. 99% of the CGI that you will see in feature films is done with PRMan (Pixars implementation of the Renderman standard). PRMan doesn't raytrace. Ever.

    Raytracing has it's place. So do a lot of other approaches. Open your mind.......

Just like now - if a friend photocopies a commerical book that you have - they can prosecute him, not you. You can't be legally required to guard a copyrighted work.

    There are 2 reasons here:

    1) They can prosecute the friend, because by the watermark they know he didn't buy it.

But at the same time the world isn't perfect. Glitches happen. You you want your neighbors to be able to know EVERY detail of your life? No - of course not. At some point freedom of information becomes an actual hinderance to getting the job done because of all the second guessing and 'monday morning quarterbacks' that are out there. For some jobs, it is important from getting from A->Z, not every last stupid little detail (and foulup) that took you to get there.

    You develop payloads for the spacestation right? When you deliver your payload do you document every foulup, screw up, bad design decision, backtrack, and everything else that went wrong during the project? I doubt it. You produce the final thing, the specs, how it has passed the requirements, etc etc. Why doesn't NASA get the same treatment?
