Abstract

Respective video feeds are provided to at least two viewers using a common display. The display is controlled to simultaneously display an image from a first video feed and an image from a second video feed. The image from the first video feed is displayed within a first wavelength band and the image from the second video feed is displayed within a second wavelength band, and the first and second wavelength bands are distinct. A first filter is selective for transmitting the first wavelength band and not transmitting the second wavelength band. A second filter is selective for transmitting the second wavelength band and not transmitting the first wavelength band. Only the first video feed image is provided to a first viewer using the first filter, and only the second video feed image is provided to a second viewer using the second filter.
