Introduction: Cinema has been the most popular

entertainment source. People of all age groups , young and old ,

women and children , flocked to the cinema halls in very –increasing numbers.

The Indian film industry was considered to be the largest and richest in the world, second only to that of Hollywood.

But now all this has changed owing to competition-first from black and white TV , then from colour TV, last of all from VIDEO PIRACY.

What is Film Piracy ? Film piracy is the illegal copying and distribution of movies in print ,video , DVD and electronic files so that people can watch

films for cheaper . This process is quit fast and simple . You can watch films that are not yet released or if you can’t afford to buy the film

legally .The film piracy began in 1998 and today it is

still easy to access as it takes a minute to find a pirated movie on internet .Longest

piracy prison sentence was 5 years given to Jeremiah Perkins from Virginia for running a

film download ring called “IMAGINE “.

Factors Responsible For Video Piracy : Screening of pirated video films in hotels,

clubs, video coached luxury buses and restaurants etc.

Video home recordings and mushrooming of video libraries.

Growth of cable television. Banning of Films creates curiosity to watch

the banned films hence raising demands for pirated films.

Sharp drop in cinema-going audience due to the law and order situation as well as bombs and fire scare in the theatres

Availability of pirated CDs/DVDs at a much cheaper rates than the original video films and various internet downloading options.

Types of film piracy : CAM- A recording device used in

the audience to capture the movie . Can contain sound from the audience over the film.

TELESYNC- A recorder used in the projection booth , which syncs the actual sound from the audio device .

SCREENER- A trial copy of the film is released to gather reviews and this is copied but contains a messages in the middle in the middle of the screen such as “The film you are watching is a promotional copy” .

A Past Piracy Problem : In June 1996, the largest ever

film piracy affair in the New York, US was demolished. The nationwide business sold over 1,00,000 films a week, earning roughly Rs.33,034,460. The investigation, nicknamed “Operation Copy Cat”, ended when search warrants were completed. 36 people were arrested and there were 817 VCR’S, 77641 printed videos, Rs 2,642,757 in case 37,000 blank cassettes, more than 1,00,000 sleeves, labels and other sophisticated equipment used in the duplicating process.”

A New Invention : A study published in 2008 found

that movie piracy, cost the environment industry more than

Rs16000 crores annually . In order to overcome this issue the

Engineering students of Electronics and Communication Department of Tamilnadu, have developed a

device that uses Infrared Sensors to fight piracy. These Infrared

sensors aare used to detect the piracy done by the people in

theatres.

Construction: The anti movie piracy device

is constructed by using Infrared sensors to fight movie piracy. These Infrared sensors are used to detect the piracy done by the people in theatres.

This anti movie piracy device uses 384 infrared light emitting diodes(LED) . These are arranged in 16 rows and 24 columns with a screen size of 300mm by 370mm to radiate a frequency of 43KHz, with 12v, 2 amp DC power supply.

Working:The Engineer who invented this

device ,explains to “The Times Of India”, 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 the screen is completely blurred, when seen through a camera, but will be clear for the human

eyes. Only the blurred white image will be captured in the camera on the other side.

So, no more printed videos, as theatre prints, can be produced (or) recorded.

For Human Naked Eye :

•The infrared rays falls on the electronic device .

•The optical water marking is created on the screen.

•Hence, when seen through the electronic device the image seems to be blurred.

When Seen Through An Electronic Device

Optical Water Marking: An optical water marking is a

two dimensional binary image. It can be of any shape and can be

printed in any type of the document. The optical water mark

is constructed by the superpo sition of multiple two- dimensional binary images each with different

structural patterns embedding various hidden information.

The hidden information becomes visible to the human eyes only when the right key is positioned on the top of the optical watermark with the right alignment.
