Camcorder Jamming Devices Announced
Adam Carrington writes "I'm definitely not behind things like DRM, but Virginia-based Cinea has an idea that I do support... jamming camcorders in movie theaters. CNET has some interesting details on how they plan on going about it. They even throw an unrelated jab at Microsoft." This might be the technology that drives the stake in analog projection.
I know. Everybody and their dog has broadband and is downloading gigs and gigs of movies off IRC servs with DCC!
Hesus, most people don't even know what IRC is! Is there anywhere else to go for movies?
If you had nuts on your chin, would they be chin nuts?
Don't Jam, just put copper mesh in the walls and make the theater a big Faraday Cage. No jamming needed so your not violating FCC regs and the RF won't get in or out. A company I used to work for had one in a lab for RF testing, no pager or cell phone could receive a signal inside.
I've seen the same effect in older buildings that used a metal mesh for plaster lath. I had to put an 802.11 AP in every room of an old house because the RF couldn't get through the walls. Cell phones wouldn't work either. Same effect in buildings whose glass windows have a high metal content.
My consumer camcorder has a variety of settings that affect the way it "sees" rapid motion. When transferring 8 mm films through one of those cheap reflector boxes, for example, the normal settings give a pulsating and unevenly bright image because of strobing. But if I use one of the "simulate slow shutter" settings, I can get very good results. The LONGEST of these settings does smear and blur motion, but one of the intermediate settings removes the flicker while adding very little motion blur.
And this is just a cheap consumer camcorder--and it's a feature that it has ALREADY.
I can easily believe that Cinea might be able to introduce short "tachistoscopic" artifacts that might screw up a camcorder on its normal settings, but if the camcorder's effective "simulated slow shutter speed" is 1/20 of a second or so, the artifacts will have to last 1/20th of a second or so to be visible to the camera--and at that speed, they'd be pretty visible to the naked eye.
I find it very hard to believe that the people who take videos off a movie screen don't know how to adjust their camcorders. Or that, if the Cinea scheme becomes popular, camcorder vendors will not respond with settings that are called by some other name but nudge, nudge, wink, wink designed to overcome the problem. Or that it can't be taken care of by some kind of digital processing afterward (analogous to using timebase correctors on analog VCR copy-protection schemes.)
In other words, it's a scam perpetrated on theatre owners.
Also, undoubtedly the "camcorder-jamming" artifacts are actually just as visible as, say, dirt specks flashing quickly by on individual frames of a dirty print. It may not make a lay audience walk out and demand their money back--they don't do that for dirty prints now. But people will be aware that the image quality isn't what it should be.
To a critical eye, DLP is currently SLIGHTLY inferior to traditional film projection in some regards (superior in others). Anything that tips that balance is going to be a problem. If the ordinary UNCRITICAL lay audience judges that "perfect" digital DLP actually isn't quite as good as 35mm and starts thinking of it as a cheap-and-cheesy alternative. I would think a cinema manager would be nuts to shell out a couple of hundred thousand for a DLP setup then add anything that would make the image quality worse.
