Two-Headed TV Set Displays Two Different Shows at Once (Mar, 1954)

Two-Headed TV Set Displays Two Different Shows at Once
Two people can enjoy different TV programs at the same time with a new set. The experimental Du Mont Duoscopic is actually two receivers in one cabinet, with two chassis, two sets of controls and two viewing tubes mounted at right angles (inset). A semitransparent mirror superimposes the two pictures, but each viewer sees only one show by watching through polarizing spectacles. Earphones handle the sound.
