Abstract
A method for receiving an input video frame is provided that generates two obscured frames from the input frame by copying odd lines interspersed with noise lines to one frame and copying even lines interspersed with noise lines to the other frame. The obscured frames are then displayed on a screen with lines polarized in different directions, and a timing signal is output to polarized active shutter glasses such that one lens allows polarized light for lines copied from the original input frame to pass through the lens and be visible to a wearer while the other lens blocks the added noise lines from the wearer's view.
