Abstract
An apparatus for partitioning, scaling and displaying video and/or graphics across several display devices includes a video source, a master device and multiple display devices arranged into a multiple display configuration. Preferably, the master device partitions the video stream into image sections and assigns each display device a corresponding image section based on its position within the multiple display configuration. Each display device then preferably receives the video stream and separates the data representing the corresponding image section. Preferably, once the data for the corresponding image section is separated, the display devices then scale their respective image sections to a full screen size image and display the scaled image simultaneously with the display of the entire frame on all display devices within the multiple display configuration. In an alternative embodiment, the master device is responsible for partitioning the video stream into image sections, scaling the image sections, encoding the scaled image sections and transmitting the scaled and encoded image sections to the appropriate display devices within the multiple display configuration. The display…
