Patent ID: 8887276

Claim:
A system for providing secure video display, comprising: an input interface for receiving a digital video data stream signal; a one-way data link having an input node coupled to the input interface and an output node, the one-way data link configured to transfer data only from the input node to the output node and to prevent any signal from passing from the output node to the input node; a processing system coupled to the output node of the one-way data link, the processing system configured to run a predetermined operating system; a video display software program for processing the digital video data stream signal received from the output node of the one-way data link and providing an output signal for viewing on a display coupled to the processing system; a software filter coupled between the input interface and the one-way data link and configured to perform data filtering of the received digital video data stream signals; and wherein the processing system is coupled to the input interface only via the one-way data link and the software filter.
