Abstract
The utility model discloses a device preventing pirating and secret shooting. The device comprises a time control part, an emission driving part and an infrared emission part, wherein the infrared emission part is internally provided with a group of infrared emission tubes for generating infrared rays; and the infrared emission tubes are connected with the time control part by the emission driving part, and the emission time thereof is controlled by the time control part. The device preventing pirating and secret shooting can effectively put an end to the pirating and secret shooting action at the source or furthest reduces the enormous economic losses of related industries caused by the pirating and secret shooting action, has low cost and is particularly suitable for being used in movie theatres.
Description
Technical field
The utility model belongs to the application of electronic technology field, specifically a kind of anti-piracy device of taking on the sly that is used in the cinema.
Background technology
Because the continuous development of camcorder technology, high-resolution, the microcam that volume is little are more and more universal, and people bring microcam into and carry out piracy in the cinema and take on the sly very easyly, make that the piracy phenomenon of taking on the sly is serious day by day.According to Motion Picture Association of America estimation, the pirated film of making in the mode of taking on the sly is annual gives loss that the film industry brings up to 3,000,000,000 dollars.
Because the infrared transmitting tube illuminating circuit can produce infrared ray invisible to the human eye, but the CCD light sensation device that uses in video camera and the camera can convert infrared ray to visible light and be filmed, therefore on the film of taking on the sly ultrared interference bright spot can appear, make it to be used to make pirated film, but this can not exert an influence to the audience ornamental film.Thereby, infrared technique can be applied in the anti-piracy device of taking on the sly.
Summary of the invention
In order effectively to prevent take on the sly the generation of phenomenon of piracy, the purpose of this utility model provides a kind of anti-piracy device of taking on the sly, and the reproduction sheet that utilizes this device to take on the sly in can making is at the cinema scrapped.
The purpose of this utility model is achieved through the following technical solutions:
A kind of anti-piracy device of taking on the sly is characterized in that: this device comprises time control section, emission drive part and infrared emission part, is provided with one group and is used for producing ultrared infrared transmitting tube in the infrared emission part; Infrared emission partly is connected with the time control section by the emission drive part and controls launch time by the time control section.
In the utility model, the emission control of infrared transmitting tube can make control as required launch time by time control section and the acting in conjunction of emission drive part, does not need the whole projection time all to launch the interference infrared ray.Infrared ray is disturbed by the emission of emission drive part control infrared transmitting tube in time control section compartment of terrain.
Because human eye be can't see infrared ray, but the CCD light sensation device that uses in video camera and the camera can convert infrared ray to visible light and be filmed, therefore on the film of taking on the sly ultrared interference bright spot can appear, make it to be used to make pirated film, but can not exert an influence the audience ornamental film.
The utlity model has following characteristics:
(1) cost is low.Compare with the economic loss that produces owing to piracy, this anti-piracy installation cost of taking on the sly is low.
(2) safety and comfort.Infrared ray is harmless, and can not cause uncomfortable feeling owing to spectators can't see infrared ray.
(3) good economic worth and application prospect are arranged.Under current situation, the film phenomenon of being taken on the sly is serious, has brought tremendous loss for the film industry.This anti-piracy device of taking on the sly can prevent to take on the sly effectively, and therefore good economic worth and social value are arranged.
As long as the utility model is installed in appropriate location on the motion picture screen, it can send the sightless infrared ray of human eye, employed RF transmitter is identical with infrared light-emitting diode on the household electrical appliance remote controller, and is safe and cost is low, is easy to popularize and promote to domestic and international cinema.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of anti-piracy device of taking on the sly described in the utility model, this device comprise time control section 1, emission drive part 2 and infrared emission part 3, in infrared emission part 3, be provided with one group several be used for producing ultrared infrared transmitting tube 31.Infrared transmitting tube 31 is connected with time control section 1 by emission drive part 2, and controls launch time by time control section 1.
In the utility model, one group of several infrared transmitting tube 31 is formed emitter array, also can have only an infrared transmitting tube 31.The infrared transmitting tube array is positioned at the appropriate location of shadow curtain, can be arranged on shadow curtain 4 rear sides, and 5 of spectators watch in shadow curtain 4 front sides.The ultrared time of emission of time control section 1 control infrared transmitting tube 31, send infrared ray every now and then at the reproduction time of film and disturb.
Groundwork process of the present utility model is as follows: time control section 1 produces control signal in the time of setting, control signal is passed to infrared transmitting tube emission drive part 2, make drive part produce suitable current, thereby drive infrared transmitting tube 3 emission infrared rays, reach the piracy behavior of taking on the sly that destroys.
Claims (3)
1. anti-piracy device of taking on the sly, it is characterized in that: this device comprises time control section (1), emission drive part (2) and infrared emission part (3), be provided with one group and be used for producing ultrared infrared transmitting tube (31) in infrared emission part (3), infrared emission part (3) is connected with time control section (1) by emission drive part (2) and controls launch time by time control section (1).
2. the anti-piracy device of taking on the sly according to claim 1 is characterized in that: time control section (1) compartment of terrain is by the emission of emission drive part (2) control infrared transmitting tube (31).
