DEVICE FOR VERIFYING THE INTEGRITY OF A DISPLAYED DATA ITEM AND RELATED METHOD

摘要

The device (40) has an input interface (46) connecting the device in parallel to a link (30) between a video controller (12) and a display (14), where the controller transmits a digital video signal in low-voltage differential signaling format to the display. A restoration unit (48) restores an image corresponding to another image displayed on the display, from the signal applied to the interface. An analysis unit (50) extracts restored data from a restored image. An input/output interface (56) connects the device to a local area network (18) conforming to Ethernetprotocol. An independent claim is also included for a method for verifying integrity of data displayed in the form of an image by a display controlled by a video controller.
