Villupuram/Puducherry: Two students of a private engineering college have developed a prototype to prevent making of pirated versions of new films screened at cinema theatres. The prototype, based on ‘infrared sensor,’ will prevent exposure of motion pictures on the screen to camera lens of all kinds. The prototype device, which should be placed behind theatre screens, would curtail all types of illegal recoding of motion pictures, the students said. K Anandhraj and A Durai Raj, final-year electronics and communication engineering (ECE) students of Mailam Engineering College in Villupuram district developed it. The device comprises 384 infrared light emitting diodes (LEDs) arranged in 16 rows and 24 columns with the screen size of 300mm by 370mm to radiate frequency of 43kHz. The device requires 12 volts and 2amp DC power supply for operation. The students said the radiation emitted from device would not be visible to the human eye and would not affect the picture quality in any way. People would be able to watch films without any blur, they said. “But, when someone attempts to record a film on the screen using a video camera or mobile phone, the radiation emitted by the device will create optical water marking on the screen. It will blur the image. Thus the motion picture image on screen is completely blurred, when seen through a camera, but will be clear for the human eye. Only the blurred white image will be captured in the camera on the other side. So no more pirated videos, as theatre prints, can be recorded,” said Anandhraj. The total cost of the prototype is 2,000.
The actual device, when produced in large scale, will cost roughly between 10,000 and 15,000. Assistant professor M Rajapartheban (ECE) guided the students in the project. The first copy of pirated version of new films are recorded in theatres and the device is expected to play a major role in curbing the menace. Tamil film industry representatives have even identified theatres where pirated versions of new films are made. Tamil Nadu film producers’ council secretary R Radhakrishnan, appreciating the students for developing the device, said the council had been taking several innovative technological measures to curb the menace. “We have been launching several technological intervention to prevent piracy. We are particularly focusing the theatres where the first copy of pirated version was recorded. About this device or any other software or technological invention meant for curbing piracy the council will discuss with the theatre owners and all those involved in the film industry to hold a trial run to test its efficacy,” said Radhakrishnan. – Courtesy
