Abstract
A video multiviewer system may include a plurality of video scalers operating in parallel for generating initially scaled video streams by performing video scaling in at least one dimension on a plurality of video input streams. The video multiviewer system may also include at least one video cross-point switcher coupled downstream from the video scalers, and a processing unit coupled downstream from the video cross-point switcher for generating additionally scaled video streams by performing additional video scaling on the initially scaled video streams. The video multiviewer system may also include a display cooperating with the processing unit for displaying multiple video windows based upon the additionally scaled video streams.
