Patent ID: 8665291

Claim:
An apparatus for providing respective video feeds to at least two viewers comprising: a control unit operable to control a display to display a first plurality of images from a first video feed and a second plurality of images from a second video feed, the first video feed comprising a first plurality of video frames and the second video feed comprising a second plurality of video frames, wherein: the first plurality of video frames includes the first plurality of images; the second plurality of video frames includes the second image; the first plurality of images from the first video feed are displayed within a first wavelength band, the colors of the first video feed having been shifted and limited within the first wavelength band by analyzing color information associated with pixels of each video frame of the first plurality of video frames and modifying the pixels of each video frame of the first plurality of video frames to be within the first wavelength band based on the analysis; the second plurality of images from the second video feed is displayed within a second wavelength band, the colors of the second video feed having been shifted and limited within the second wavelength band by analyzing color information associated with pixels of each video frame of the second plurality of video frames and modifying the pixels of each video frame of the second plurality of video frames to be within the second wavelength based on the analysis; a first viewer viewing the display using a first filter that passes through the first wavelength band and not passing the second wavelength band views only the first plurality of images from the first video feed; and a second viewer viewing the display using a second filter that passes through the second wavelength band and not passing the first wavelength band views only the second plurality of images from the second video feed.
