ES2249166A1 - Camera recordings scrambling device for detecting video piracy, captures pirate images by recording light emitted from infrared diodes mounted behind cinema screen - Google Patents

Abstract

Infrared diodes mounted behind a cinema screen emit light that cannot be seen by the human eye, but is recorded by video camera to capture pirate images. A main power supply source and an alternative automatic autonomous source are provided so that the alternative source powers the diodes when the main source fails. An independent claim is also included for still and video camera scrambling system.

Description

Video camera disturbing system and Photography.

Object of the invention

The present invention relates to a system disturbing video cameras and photography.

Background of the invention

Currently the piracy of movies from cinema and other events, such as live performances and the like, has reached such levels that is frequent, for example, find pirated copies of a movie the same day of its premiere, either in physical support or, above all, on the Internet.

These pirated copies are recorded by cameras in the cinema or the theater itself, during the screening or event representation, and often in previews or evidence, even by people linked from one another by form to the cinema or show room or production company.

This phenomenon causes huge losses to the film and entertainment industry, and affects the higher prices, inconvenience to be corrected by using the system of the invention.

Description of the invention

The system of the invention serves in a manner Optimal for disturbing the image collected by the video camera / s or photograph used to obtain pirated copies of a screening of a movie or live representation of a event, reducing the quality of collected image and even offering the possibility of identifying the source or cinema in which The copy is obtained.

According to the invention, the system is constituted by a plurality of light emitting elements recordable by cameras but imperceptible to the human eye, such as infrared light.

These elements are arranged in the area of the representation or projection of images likely to be copied or hacked, and have a main power supply, preferably network.

When you get the images, pirate cameras they also record the light emitted by these elements, which will be visible in the reproduction of the pirate copy, disturbing its quality and minimizing the possibility that it may be interesting compared to an original of the same event, even in spite of the cost difference

In addition, the emitting elements can be arranged of light in such a way that they "draw" or somehow trace the identification of the cinema or location of the pirated show, or any other data that can be used later to Locate the origin of the pirate copy.

Brief description of the drawings

Figure 1 shows a system view of the invention in a simple embodiment variant for a cinema, with A running sneak.

Figure 2 shows a side detail of the placement of the light emitters on the back of the screen movie theater.

Figure 3 shows a view of Figure 1 in a variant embodiment of the invention with power Autonomous automatic alternative and communication of incidence to a remote surveillance center.

Description of a practical embodiment of the invention

The device 1 of the invention is constituted  by a plurality of 2 spectrum light emitting elements recordable by cameras 3 capable of obtaining copies fraudulent event -projection of a movie in this example-, but not appreciable by the human eye. In this example no limiting the invention, these elements consist of diodes infrared light emitters, preferably arranged behind of the cinema screen 5, as seen in figure 2.

The infrared light crosses the thin screen and it is collected by cameras 3, which will therefore obtain an image disturbed since in the reproduction of the fraudulent copy yes the light emitted by elements 2 will be visible to the human eye, which however is not visible during normal playback or in Direct from the movie.

The quantity of diodes 2 will be the one necessary for achieve the end pursued, and the disposition can be any, either by configuring drawings (for example, a skull as a hacking symbol) or tracing alphanumeric symbols that can serve to identify the movie theater. Also, the emission of diodes 2 can be fixed or intermittent, in its in whole or in part.

Diodes 2 will be powered by corresponding power supply 6, preferably consistent in an adapter that can be connected to the mains.

In addition, the system can incorporate an autonomous power supply 7, such as a battery of rechargeable batteries, switching normal power to the autonomous in case of accidental or provoked disconnection of that, so that diodes 2 continue to emit. All this in order to prevent pirated copying if you disconnect for this purpose the main or general diode power.

Additionally, it can also be incorporated to the system a bright and / or acoustic feed sneak 8 of the diodes, which allows the effective verification of their functioning.

In addition, an appropriate interface can be implemented 9 (for example a modem or mobile phone) so that, in case of disconnection from the main source, a notice is sent to a center of surveillance, managed for example by related entities with the rights holders of the movie. This notice is would generate in case of disconnection of the main power and that a photodetector element 11 arranged the screen, and optionally constitutive of the system, detect that the movie is being projected.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.

Claims (7)

1. Disturbing system of video and photo cameras; characterized in that it is constituted by a plurality of light emitting elements that can be registered by the cameras and imperceptible to the human eye, arranged in the area of representation or reproduction of the event that can be copied. 2. System according to claim 1 characterized in that it has a main power supply to the network and another complementary autonomous power supply and alternative automatic operation in case of failure of the main power supply. 3. System according to claim 1 characterized in that the light emitting elements consist of infrared light emitters. 4. System according to claim 1 characterized in that in the event that the event that can be copied consists of a movie film, optionally one or more photodetector elements are arranged on the screen, in order to detect if the film is being projected . 5. System according to claim 1 characterized in that optionally can incorporate a sneak operation of light emitting elements. 6. System according to claim 4 characterized in that an communication interface with a monitoring center is optionally incorporated in order to notify the disconnection of the main power supply if the photodetector element detects that a projection is taking place. 7. System according to claim 1 characterized in that the light emitting elements, in the case of a cinema, are arranged on the back of the screen, and adjacent thereto.
