The two prints can be broadcase simultaneously, one in green and the other in red. However, it would be awful to watch on a B&W TV. BTW, let's not forget the totally bad 3D movie from two years ago, "Parasite". This was so bad that even the 3D part was backward! One had to wear the polaroid glasses upside down to see the 3D effect.
