Abstract

Novel systems and methods for preventing piracy of motion picture images by recording the images as they are displayed on a movie screen, using a camcorder as a recording device. Two alternative anti-piracy systems and methods are described. The first method is to vary the frame rate of the displayed motion picture images in a random fashion, thus preventing the camcorder from synchronizing its internal frame rate with that of the displayed motion picture image. The second method is to transmit pulsed energy with frequencies in the frequencies of visible light, such as red light in a manner with sufficient transmitted power or frequency to degrade the quality of the recorded image by the recording device. The result is significantly degraded quality of the recorded ima ges. The two embodiments can be used alone or in combination.
