Abstract: A television monitor accepts two video programs simultaneously, by ordinary transmission, cable, a VCR, other means or any pair of such means, and by providing the two programs as light transmissions in two mutually orthogonal polarizations, together with eyeglasses adapted to select one or the other of the two polarizations, two or more users are enabled to watch one or the other of two different programs, at the same time on a single display screen. Selection of which program a user wishes to watch is accomplished by adjusting a polarizing lens within the eyeglasses so that the polarization of the light that will pass through the eyeglasses is matched to one or the other of the two polarizations of the light being emitted by the display screen. The eyeglasses include automatic adjustment means that will compensate for movements of the user's head that would otherwise place the glasses out of angular alignment with the light from the display screen.
