An FPGA implementation of multi-channel video processing and 4K real-time display system

摘要

An Field-Programmable Gate Array (FPGA) implementation to merge and process the Multi-channel independent videos and reconstruct 4K real-time display system is presented. The video system is capable to receive multi-channel Full High Definition (FHD) (1920 × 1080 pixels) videos, to process each video channel and to reconstruct and display the merged video up to 4K (3840 × 2160 pixels) Ultra High Definition (UHD) format. To guarantee the high efficiency and less delay, we adopt the parallel processing design and `hardware' based structure. The multi-channel independent video can be processed at the same time to ensure real-time display and each channel video could be displayed stably in 4K format. Additionally, Xilinx spartan-6 FPGA module works as the core hardware to control the input, video reconstruction and output processes. High-speed memory chips double data rate type three synchronous dynamic random-access memory (DDR3-SDRAM) and high-frequency Printed Circuit Board (PCB) with ten layers layout are used to ensure the efficient cache of video data and integrity of video signals. This FPGA based real-time UHD implementation can be used not only for modern surgical, patient monitoring, diagnostics, but also for office meeting, video surveillance and so on.
