Disney Encrypting Screener DVDs to Prevent Piracy

Sascha J. writes "Disney is continuing their war against piracy. To their Oscar reviewers they now send out special encrypted DVDs, which can be played only on a DVD player of the "Cinea" series. From the article: "The DVD players are encoded with recipients' names, and screeners sent to those people are specifically encrypted so they can be seen only on those particular DVD players." Yet, Disney is alone on this. Sony and Universal Pictures said they won't follow that step."

      Nothing, but there are a few deterrents:

      -A small reduction in quality (Boo hoo)
      -The time it takes to play the whole thing, then recompress it. (Of course, you could just do the first while you're watching it, and the second overnight.)
      -Much higher chance of having interrupts, skips, etc. (Blah)
      -You lose the DVD menus! (This would actually matter.)

      Basically, the same reason people choose to disable the copy-protection on those new CDs that Sony has been putting out, rather than playing-and-recording. Plus the DVD menus.

Think it as a personalized version of the movie with the screener brown dots. The dots would not just be print copy number.

      With those companies as the basis for my statements, the screeners for direct-to-video films and about-to-hit-DVD films are fully-featured with all of the bonus materials and menus that you'd get if you purchased the DVD. Some things may change when the DVD hits stores (bonus features added, changed menus, things of that nature), but generally, they're the same thing you'd purchase from your retailer of choice.

      Screener copies of movies that are currently in theaters or are about to hit theaters are bare-bones. You get the typical piracy warning before jumping to a very simple menu (with nothing more than "Play Movie" as an option), or it goes straight from the warning into the movie.

      You miss the point - these screener DVDS are *very* limited in number - they are DVDs sent off to the people who vote in the Oscars. Each of these is then watermarked with the name of the person who recieves the DVD for reviewing. Then if copies do surface then Disney can analyse the footage, say - it is you who has copied it! and maybe sue the dude to whom the DVD was provided to and at least not give them anymore.

      Disney have now gone a step further by saying it will only play on one range of DVD players. This is probably because the last time they caught someone for bottlegging stuff, the actor Carmine Caridi had 'lent' the DVDs to a friend who he thought was just a film buff.

      Looking it up on the web the whole story has a tragic end for the pirate involved.

      So, yeah they can be copied and distributed. But it makes it too traceable, too much hassle and a recipient has too much to loose, to make the whole thing worthwhile.

      To move to the topic of general piracy (nothing to do with the story, but it's what made several people strangely moderate up your post), and to generalize, there are two primary kinds of pirates: there are the hardcore pirates who think the world owes them, and it's their god given right to pirate DVDs (they'll have the long littany of reasons why they should be able to pirace. The most humorous is the paradoxical "movies and music are so terrible anyways, that they don't deserve my money"), then there are the everyday keeping-up-with-the-Joneses types. The latter kind is actually vastly more common than the former, and they pirate simply because they see everyone else doing it, and they don't want to be the sucker (the power of social proof and context).

      For the latter half you just need some half-decent "make it some trouble" measures, as well as some legal deterrents. Already the RIAAs lawsuits have scared a large number of people away from the warez scene (which, incidentally, thins the herd and makes the hardcore pirates more visible), but even then the industry was tempered in that it said that it was only going after major distributors - if they randomly went after some guy who had one song or movie available for upload (usually inadvertently courtesy of their tool, as most keeping-up pirates just want to leech, get their stuff and get out), the warez scenes would absolutely dry up.

While most televisions experience an "ebb and tide" of fading, some televisions respond by only showing distortions at the high and low ends -- e.g. your black bars every few minutes.

      The NTSC video standard (the broadcast standard used in North America and Japan) is defined with a 525-line vertical resolution. However, only 480 of those lines are used for transmitting video information. The extra 45 lines are used to carry control codes (such as interlace information), closed captions, and other similar non-video content. Macrovision copy protection works by adding certain codes to these control lines that are interpreted by an Automatic Gain Control chip in a VCR to scramble the video signal if the video is being recorded. Videocassettes that are copied from Macrovision-encoded source material will frequently exhibit color loss, image tearing, variable brightness, and picture instability. Since TVs and video switch boxes do not have Automatic Gain Control circuitry, the Macrovision signals are ignored when the DVD player is connected directly to the television, or indirectly through an A/V switching receiver or switchbox.

    Logo removal has come a long way. If you track objects as they fall under the opaque area, you can find when they are opaque and when they are not. You can calculate what area of the screen is opaque and you can adjust for it. A quick Google search turned up LogoAway and DeLogo.

    Watermarks are more of a problem. I don't think I'd let a screener DVD out my door without comparing it to another screener DVD for watermarks. The biggest problem is that you aren't supposed to know if a watermark is even there without knowing its design. That means you can't really ever be sure that there isn't watermarking unless you compare two sources.

  24. Digital watermark, rather by haggais · · Score: 5, Informative

    Actually, the wonders of modern technology suggest a rather simpler solution. Digital watermarking of video streams is a fairly well-developed field, with several companies offering working products. The "invisible" watermark is some extra bits of "payload" added by some transformation of the images -- nothing which perceptibly degrades image quality -- and can be recovered again by some simple transformation of the data.

    Algorithms exist which embed this information "visually", in the sense that it is distirbuted across the whole or much of the image, and it survives "classic" image processing such as resizing, lossy compression, and recolouration of the image (not to any degree, of course, but you'd be ruining the movie before you got rid of the watermark), rather than just being a few specific bits which can be deleted or edited. Some of these techniques are also intended to be tamper-proof, in the sense that without the watermark-creator's key it is very hard to know how to remove or alter the watermark.

    Such a watermark would seem to be much better than a glaring visual signal, for tracking down the originator of a leaked copy. It wouldn't stop viewers enjoying their leaked copies, but the leaker could be held accountable.

It was social, people could actually _talk_ to each other about it and they could have the rep answer viewers questions and no hope of the screeners geting duplicated bar shaky-hand-cam action. I would theorise that this is because they save a bit of cash by doing it via mail with a DVD instead. But they claim their losing millions due to the pirated pre-release getting out?! Do the math!

    I want to know what is economically gained by this? Screeners are sent to select people, and these select people are taking advantage of lack of supervision to leak their copies. Wouldn't it be much cheaper and simpler to fly them in and give them all the access they need to the films without giving them a copy rather than going through this massive infrastructure expense. Think about it... a few plane tickets once a year, or paying to produce limited number of cinea machines with virtually no economics of scale, paying royalties for the copy protection scheme, paying for administration regarding registrations, paying shipment, paying to have those dvd's specially processed, paying possible tech support for said machines, and still potentially (more like LIKELY) having material leaked? It just seems dumb. A lot of people are falling into this bounded thought trap that everything needs a high tech solution. My networking professor said it well, UPS is still has higher bandwidth for transferring large amounts of data than the internet does, and once you reach a certain threshold as far as a single file's size, it's just cheaper and faster to mail it, but i'll bet most netizens wouldn't think of that.

    I have worked in television for over 20 years and during part of that time worked in a facility that duplicated screeners.

    I think everyone needs to realize that the production of these illegally pirated films from screeners is an inside job. Unless Disney wants to set up and maintain a secure duplication facility somewhere, staffed only by trusted individuals who are constantly monitored for theft, there will always be those who "make a few copies for their friends."

    Disney isn't about to do this because Disney is in the filmmaking and entertainment business, not the mass duplication and standards-conversion business. And it is from those facilities that the content leaks out. Try as they might, unless they spend a whole lot of money that, on its face does not please their shareholders, they're pretty much stuck with these inside jobs.

    As to the high-quality bootleg copies, that tends to be the result of running an "extra" master of the film transfer and is either an organized crime issue or "yet another inside job."

    Disney just wants to make a profit. They have their reputation from the old days to rest on, and now they pretty much get by on name recognition. They make (most) movies on the cheapest budget and target audiences such as young teenagers that don't know any better. These young men and women drag their parents along to the theaters and the DVD stores to spend money. Disney makes tons of cash, and everything works fine for them.

    This is not always true, however. For being cliched and unoriginal (based off an amusement park ride and every other pirate movie), Pirates of the Carribean was, in my opinion, an excellent movie. Besides outstanding acting and directing, the one man responsible for it not sucking was Jerry Bruckheimer. As far as producing goes, that man has the Midas touch. While I think there are too many CSI shows and they get old, he still does a good job producing them. He did a good job on Pirates of the Carribean. I haven't checked, but I hope he produces the sequel too.

  32. My watermark solution as a filmmaker by Quizo69 · · Score: 2, Interesting

    I have just directed my first short film and it is now in post production. I plan to release it online next year for free, once it has completed the festival circuit.

    However, that said, the concern I have is early, unfinished copies of the film getting out, or rushes, or other intermediate stuff that would diminish the enjoyment of the final product by being released early.

    So I have an elegant an unobtrusive solution to track the few copies that people are working with as a matter of necessity:

    My watermark is done per copy so it is unique, and involves changing three to four pixels only on one frame of the film in minor ways so they are not easily visible to the human eye when watching. Shift the colour of some pixels by only a couple of points, such that they are damn close to the real thing, but obvious if you know which frame to check and where, when blown up to 500% or so of original size.

    Then simply keep a database of the "security dots" and where they are in each copy, eg:

    45332 700 431 0 0 8

    The above is frame 45332, X position 700, Y position 431, and the colour in RGB format. Three or four of those and a list of who has that copy, and I'm 100% able to figure out who leaked without degrading the picture in any visible way.

    It isn't intrusive like CAP codes, and keeps everyone involved in working on the project from leaking copies as they know it can be traced back to them.

    Why can't Hollywood studios do it the same way?

  35. N+1 Algorithm by Myria · · Score: 3, Interesting

    Watermarks are generally useless when considering the N+1 algorithm. If you suspect a watermark, get a second person to leak it. Do a binary comparison between the two. Wherever they differ, change those bytes to a value that is neither one nor the other. Get a third leaker. If any new locations show up, repeat and get a fourth leaker. Otherwise, you're done.

    "N+1" refers to how you are defeating a cross-tagging system against N people by having N+1 collaborate. For simple per-person tagging, N=1, so you need 2 people to collaborate to remove the tag. The third person is only there to prove that there are no more tags.

    There are two ways you can try to defeat this. One is to make N quite large, for example by putting tags that identify pairs of viewers, triples of viewers, etc. that would catch people collaborating.

    The other way is to make the tag part of the encoding process, such that (almost) the whole disk changes for each viewer. The problem with this is that MPEG2 encoding takes many hours, and would have to be done for each viewer individually. Also, it would need to be sophisticated, as it would have to survive recompression. The pirates would be able to spot this, however, and do a frame-by-frame (+/- a few frames to thwart frame addition/deletion) comparison and randomize or average anything that changes.

    Personally, if I were a recipient of such screeners *and* I wanted to pirate them, I would give the disk to someone and stage a break-in of my house.
