Abstract
An apparatus and method for displaying a copy-deterrent pattern () within a digital motion picture in order to discourage recording of the motion picture using a video camera or other sampling recording device. A copy-deterrent pattern () could be, for example, one or more symbols, a random pattern, a digital watermark or a text message (). The copy-deterrent pattern () comprises a plurality of pixels within each frame of the digital motion picture, and the displayed pixel intensities are modulated at a temporal frequency using modulation characteristics deliberately selected to be imperceptible to human observers while simultaneously producing objectionable aliasing in any copy made using a video camera.
