Abstract: An adjustable-aspect ratio video projection viewing screen assembly has a screen portion that is basically proportioned as a widescreen, e.g. with 16:9 aspect ratio, but is convertible to a second aspect ratio, e.g. regular 4:3 aspect ratio, by means of a pair of telescopic side panel assemblies, each having a fixed portion extending outwardly beyond the side edge of the widescreen, and a movable portion that can be located in front of the fixed portion for widescreen viewing or moved inwardly to cover the void side margins for viewing at regular aspect ratio. The fixed portions also serve as stereo speaker baffle boards, the movable panels being made acoustically transparent. The movable panels may be adjusted manually or can be fitted with an electrical power mechanism controlled manually or controlled automatically from an aspect mode control signal originating from the video projection system. All four panels are typically covered with matching grille cloth.

Abstract: An optional beam aspect control device enables a video projection system designed for standard aspect ratio (e.g. 4:3), to operate from widescreen-formatted video source material and to project an image with a wide aspect ratio (e.g. 16/9), without loss of picture information or resolution capability and with no risk of source screen burnin due to blank top and bottom regions. A reflector, introduced in the video light beam between the projector and the viewing screen, can be curved in one axis, either manually or by a controllable electric mechanism. The reflector is typically kept flat for operation at the standard aspect ratio (4:3) and then controllably curved to display images in non-standard aspect ratios. The source image outline is always kept optimally registered on the source screen for full screen utilization with no blank top and bottom regions; consequently, when the system operates in a non-standard aspect ratio mode, the source image is forced to operate at an offset aspect ratio.
