Abstract
A method for distributing video in a display system equipped with at least one camera. The video is distributed among multiple display zones, which are movable with respect to each other. The method includes acquiring optically, with the camera, a calibration image of a display zone of a display-enabled electronic device. The method includes computing, based on the calibration image, a coordinate transform responsive to dimensions, position, and orientation of the display zone relative to the camera, the coordinate transform being usable to effect video rendering on the display zone. The method includes transmitting to the display-enabled electronic device one or more of the coordinate transform and video rendered for display on the display zone based on the coordinate transform.
