A system and method is presented for enabling the viewing of multiple, different programs simultaneously on a single television display. The system can use alternate frame sequencing to alternate the programs frame-by-frame. A first pair of shutter glasses received a synchronization signal from the television and controls both the left and right glass in tandem to view the first program, while a second pair operates similarly, but uses the same synchronization signal to view the second program. Alternatively, the system can use polarization, in which a first program is polarized in a first orientation while a second program is polarized in a second orientation. Polarized glasses with matching orientations allow the user to watch only a single program.
