The movie trade sees illegally recorded films as one of many largest piracy threats and goes to extremes to cease it.
Over the years, movie theaters have used audio and video watermarking instruments to detect pirates, for instance. And through distinguished occasions, night-vision goggles and different spy tech is used to watch movie goers.
Most anti-piracy efforts aren’t notably pleasing for the basic public, however a model new know-how from Philips hopes to vary this. In a current patent application the know-how firm proposes an ambient lighting system for movie theaters that can hinder pirate recordings.
The main movement image studios are dropping giant quantities of cash attributable to piracy. The worldwide movement image trade, distributors, theaters, video shops and pay-per-view operators, lose annually billions of dollars because of piracy, the corporate begins.
Philips notes that most of the present safety measures, comparable to watermarking, make piracy traceable. Nevertheless, they dont forestall precise recording and distribution. Watermarks can be merely rendered ineffective if pirates take away them afterwards, for example.
The drawback with present safety measures in digital cinema is that they don’t forestall pirates from filming the content material from the cinema display. Watermarks will help to determine the supply of pirate content material, but it surely doesn’t forestall the precise copying and spreading of the content.
The ambient lighting resolution is different and Philips believes that it might scale back piracy substantially.
The idea is sort of simple. By shining gentle on the guests from the facet, at a sure frequency, the pirate recordings can be severely degraded up to some extent the place theyll develop into utterly unwatchable.
The resolution proposed right here is to shine seen gentle from an (additional) gentle supply with a pre-determined modulation frequency on the cinema display whereas the movie performs, the patent utility reads.
When the frequency is chosen effectively, a digicam will be unable to correctly movie the content material, as a outcome of the sunshine supply runs out of sync with the digicam leading to stripes working by way of the movie content.
The thought is partly impressed by Philips current Ambilight know-how for TVs. This generates lighting results across the TV that correspond to the video content material. The cinema setup will do the identical whereas hindering pirates within the course of. A win-win state of affairs, in accordance with Philips.
It is but an additional side to supply a extra immersive expertise when watching video content material on a show gadget together with anti-piracy measures, the patent utility reads.
Its unclear whether or not there are concrete plans to roll out the know-how at movie theaters. Philips, nevertheless, is not any stranger to those sort of anti-piracy options. The corporate beforehand rolled out CineFence, a forensic marking know-how for each image and sound, focused at digital cinema content.
In any case, its advertising message to get movie theaters to attempt ambient lighting. Whether or not its actually efficient has but to be seen though.
