Abstract: In one embodiment, an apparatus having a processor configured to: receive a first video image captured by a first camera via a first polarized filter having a first polarization, the first video image pertaining to a first display at a first location; receive a second video image from a first logic device, the second video image captured by a second camera via a second polarized filter having a second polarization, the second video image pertaining to a second display at a second location; transmit the second video image to the first display; control the first display to display the second video image, the first display having a third polarization substantially opposite from the first polarization; and transmit the first video image to the first logic device, the first video image to be displayed onto the second display having a fourth polarization substantially opposite from the second polarization.

Abstract: In one embodiment, an apparatus comprises a first camera configured to receive a first image via a first polarized filter, a second camera configured to receive a second image via a second polarized filter, a first projector coupled to the second camera via a communication link, the first projector configured to project the second image onto a first presentation screen via a third polarized filter, the third polarized filter being substantially opposite in polarization from the second polarized filter, and a second projector coupled to the first camera via the communication link, the second projector configured to project the first image onto a second presentation screen via a fourth polarized filter, the fourth polarized filter being substantially opposite in polarization from the first polarized filter.
