Abstract:
A target controller for remotely controlling at least one of an external target switch and an external target computer, the controller comprising:an analog video interface for receiving analog video signals from the at least one of an external target switch and an external target computer; a digitizer for digitizing the analog video signals received from the analog video interface; a first logic device configured to divide the digitized video signals into blocks of digitized video; a second logic device configured to compare a first block from a first frame to a second block from a subsequent frame; and a third logic device configured to send only pixel values that changed between the first and second blocks, wherein the analog video interface receives analog video signals from an external target switch, and wherein the first logic device comprises a fourth logic device configured to switch a current connection of the external target switch such that the analog video signals change from a first computer to a second computer.
