| Abstract:The display is an important device of information equipment. The splicing of multiple videos on the display can not only monitor and view from a large perspective, but also solve the problems of target occlusion and multi view display disorder in a single camera video. This paper is designed a display with multi-channel video splicing based on FPGA. The design of the display selects the FPGA of Fudan Micro JFM7K325T large resources as the processor, and is equipped with two Unilc’s 16Bit SDRAM high-speed memory chips as the image caching module. It supports SDI and HDMI digital video input interfaces, and provides 4-channels FPD-LINK high-speed digital video interfaces, three infrared video images with a resolution of 1280 * 1024 are processed into three 640 * 720 resolution images by FPGA through three channels of this video interface to fill the 1920 * 720 resolution display screen, and the images are displayed in real time, finally achieving the purpose of video splicing. |
