Abstract

A method for frustrating piracy of a movie, the movie including a plurality of filmed frames, each of the filmed frames including an image, the method including editing the movie prior to projection such that different regions of the image of one of the filmed frames are in different frames so that the different regions will be projected at different times, and repeating the editing for other ones of the filmed frames. Related apparatus and methods are also described.
