Abstract: A 3D image projector having a translucent rotatable hollow cylinder, the hollow cylinder having differently polarized sections, and the projector being capable of passing a light beam generally orthogonally through a wall of the hollow cylinder is disclosed.

Abstract: A method for control comprises a set top box receiving coordinates from a touch sensing screen. The coordinates are interpreted for controlling the set top box, and in accordance with the interpreted coordinates an action is performed. A further method for control comprises a set top box receiving a signal representative of displacement. A control function is determined from the displacement representative signal and the control function is activated. In accordance with the control function a signal is formed for communication.

Abstract: A video processing apparatus may be controlled in response to selecting an advertisement displayed in connection with a productivity or communication application software program being operated on a video processing apparatus. The advertisement includes control information, which is used by the video processing apparatus to control an operating mode thereof. The control information may include both time and channel data as well as a recording data for programming a timer. Alternately, the control information may only include program data, which is passed to the electronic program guide to determine the time and channel information associated with the program data.

Abstract: The present invention provides method for producing a substantially seamless video image on a display surface. The method comprises the steps of separately projecting at least a first and a second video image onto a display surface such that a seam is defined by overlapping portions of said first and second video images. Inside the seam, the brightness of the first video image and the brightness of the second video image are adjusted electronically so as to provide a uniform brightness profile.

Abstract: A segmented display system in which the display devices are arranged in a N×1 array is described. The segmented display system includes a plurality of projection devices that each project a portion of an image on a corresponding one of the display devices in the N×1 array. Distortion from extra light is minimized using a moveable mask around each projection device lens in the N×1 array.
