The Video Pattern Generator card (VPG) is video test equipment, used for emulating desired test patterns for testing functionality and evaluating performance various video processing systems. This VPG has been specifically designed in order to meet the functional and mechanical specifications of the Link Test Simulator (LTS) System designed by Aeronautical Development Establishment. The VPG card provides one input video channel for external video data coming from any PALB supporting video source. It provides two video output channels for any PAL-B supporting video sink. The output video can be selected from either the input video channel or the NAND flash memory. The NAND flash memory is used to store the desired video sequences and is programmable using the graphical user interface over the USB interface.
