Abstract
A system for providing a secure video display using a one-way data link. An input interface for receives a video stream signal. The one-way data link has an input node coupled to receive the input video stream signal and an output node. A processing system is coupled to the output node of the one-way data link and is configured to run a predetermined operating system. In an embodiment, a video display software program operates within the predetermined operating system to process the video stream signal received from the output node of the one-way data link and to provide an output signal for viewing on a display coupled to the processing system. Optionally, the video display program operates within a virtual operating system running within the predetermined operating system. In other embodiments, the video display program may process a video stream signal containing a plurality of different video programs.
