Movie piracy...

Image and video hosting by TinyPic
Many movies are pirated using a camera
in theaters.
Maybe some of you don't know
that any camera "sees" infrared light.
To test it, pick your camera and aim
a remote (your tv remote is ok) at it.
You will see the infrared L.E.D. blinking.
Well.. I was thinking...
What if many infrared leds will be put behind
the projecting screen in theaters?
The IR light won't be seen by people.
But it will appear in recorded videos :)
Obviously this could be defeated putting an IR
filter on the cam lenses.. but that's the road imho :)

I like your thinking! such genius.

good idea didn't think you could see it through a camera but it tried it so cool.

dale said...

Glad to see a post from you, after such an absence

Kraig Roche said...

very original
i wonder how expensive that would be to actually do though

salami said...

There exist several technologies based on light tricks more advanced than simple infra-red LEDs.

Cockroach said...

Except it would blind people. Just because you can't see it, doesn't mean it isn't harmful.

Donald said...

Very nice, but it couldn't be defeated that easily. I use a IR Filter on my D-80 and is almost black. The sun has a hard time getting through it. about 99.9% is blocked, so the movie screen will still not be seen with the filter.

mike said...

wouldnt that make it like extreeemly hot, aiming IR light at the audience?

hdnova bossman said...

That is a good idea! Though I never download Cam movies, i cant watch crap quality, prefer blu-ray rips ;)

temporary said...

this is already done in movie theaters...

Kwaku said...

HI Zibri. can you give unlock codes for the google G1 android too??? whats up with the iphone 3g unlock as well. Please let me know asap about the G1.

Zibri said...

temporary:
I didn't know that.
And that doesn't happen here in italy.

Zibri said...

dale:
thanks.. Yes.. I'm pretty busy with real life in this period..

gp said...

hey zibri!
real life is indeed more important! ;)
and thanks for the great work you've done!
best wishes from austria!

This is a clever idea. But as Donald already pointed out, it's just a small challenge to overcome this kind of security.

Willmaster said...

many Telesyncs and Camrips are from Russia/Ukrain , and there this equipment is expensive and no one cares about the Rippers

also, most cammers using Sony HD camcorders , which have an IR Filter integrated , and every cammer will see on the Monitor that ther is something false :D
and IR LEDs are producing a immense Heat , you cannot cool so many Leds

at the moment EVERY secure is useless, also the "second picture" is detectable by special filters for vdubmod used from scene groups , if there are no more cam rips there will be more Screeners/DVDscreeners , and these are not Protectable

Eugene said...

Its don't worthy to put this infrared light in every theater because people who want to pirate will pirate any way, the IR filter is no so expansive, besides the quality on camera come out very poor and that's the main reason that not everyone in theaters siting with cameras, so its a free anti pirate block.

chilly willy said...

it would be so expensive to put millions of led's behind the screen, the enought to screw off a recording, but i dont know, maybe just a few can srew enought a recording to make it ugly.

daijizai said...

Donald: Sure could... Just need a pass filter that lets through only the visible wavelengths.

aakash said...

i g2 this IDEA 3 yrs back dude
When my robot had all infrared detector s with heat sensors
I saw the pictorial difference

PROBLEMS IN USING
1) Big Infrared Heavy waves need to be emitted releases large amount of heat
2) Special lens easily by passes it as it does not take infrared in view
3) Its expensive damn expensive also creates a screen projector problem it needs covering and all dat crap and the filter for it is not even 100$ dude
4) They are electro magnetic large amt is not good for gadgets!!

Work on liux then this TP

I m not dat good at AT codes
Or i too would <3 to help

I m using linux in iphone its good project man....
D mobile installation was made by me but this jailbreak stuff is too time consuming so cant help it!!
Atleast appreciate Dev team in a new topic!!
They r doing an amazing JOB
more den amazing JOB
Linux is progressing with speed of lightning!!

Just my personal view
no competition

AFAIK this already used in some US Cinemas.

The beam has a kind of "code" in it, so once the movie goes on the internet, they could be able to understand where, when it has beeen filmed and possibily who (based on the prospective).

Tom said...

Sorry, Zibri, but I'm not convinced. Cinema screens are very bright. Small infra-red lights would have the effect of shining a torch (flashlight) in a very bright room: barely noticeable.

temporary said...

oh, i forgot you were over seas. in the united states, lots of theaters utilize this.

Sebas said...

it's already invented and patented by a spanish man.

Zibri said...

Oh.. I didn't know, but I guess I wasn't the only one to have this idea.

Marcelo said...

Well I thougth of that once, but then again: the image quality SUX soooo bad and audio is often terrible as well, not to mention people in the audience talking and walking up/down the hallway, do we really need a hint to know its a pirated copy??

Zibri said...

It seems it wasn't such a dumb idea afterall..
