Development of New Technology in Preventing Movie recording Piracy
This new technology would probably put an end to movie piracy, well may be for a while at least. The newly developed technology specifically targets the individuals who record movies at the movie theater by their camcorders. National Institute of Informatics (NII) Associate Professor Echizen and Sharp Cooperation developed a technology for preventing pirates from recording films at movie theaters. This technology focuses on the differences of sensory perceptions between humans and devises through use of near-infrared signal as noise signals which is not harmful to human as well as being invisible to human eyes capable of adding noise to shooting video through CCD/CMOS device. The screen in Movie Theater has 1-2 mm in diameter holes which are originally designed to combine sound and video, by placing infrared light emission unit on back of movie screen; infrared light gets through these holes and flashes pulses of the infrared light. This technology is expected to contribute not only in preventing movie recording piracy at movie theaters but also for copyrights protection of various displayed medium such as digital signage.
