Abstract
Systems enable viewing of video images over a plurality of scalable modular video displays include a video wallpaper subsystem and a video central computer subsystem. The video wallpaper has video displays having a same pixel pitch, and a width and height. The video displays include a video scaler and video mixer configured to enable video signals provided to the video displays to appear as one of a single video image a plurality of separate video images. Each of the video images appearing on a subset of the video displays as an overlay over the single video image, wherein the single video image and each of the plurality of separate video images are displayed at predetermined resolutions. The video central computer subsystem includes a video processing unit which receives video signals from a plurality of video sources and selects video signals to process and send to the video displays and includes a synchronizing frame buffer with time base correction to provide video synchronization of the selected video signals.

13. A system for enabling viewing of video images over a plurality of scalable modular video displays comprising:
-
a) a video wallpaper subsystem including; at least two first video displays having a same pixel pitch and a first height and width; at least two second video displays having said same pixel pitch and a second height and width, wherein the second height and width is smaller than the first height and width, said second height is evenly divisible into said first height and said second width is evenly divisible into said first width; wherein said first video displays and said second video display are for being horizontally and vertically arrayed on a flat surface; each of said first video displays and second video displays including a video scaler and video mixer configured to enable video signals provided to said first video displays and second video displays to appear as one of a single video image on said displays at its native resolution and a plurality of separate video images, each at its native resolution, each of said plurality of separate video images appearing on a subset of said first and second video displays as an overlay over said single video image; b) a video central computer subsystem coupled to said video wallpaper subsystem, said video central computer subsystem including a video processing unit which receives video signals from a plurality of video sources and selects video signals to process and send to said video displays from said plurality of video sources, and includes a synchronizing frame buffer with time base correction to provide video synchronization of the selected video signals when said single video image and said plurality of separate video images are displayed on said video displays. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
