Description

technical field [0001] The invention relates to an FPGA-based multi-channel HDMI interface-to-PCIe video processing and acquisition system, belonging to the technical field of video processing and acquisition systems. Background technique [0002] Most of the existing technologies use the existing HDMI receiver as the signal processing and receiving unit. When the number of hdmi channels to be collected increases, the cost will increase significantly, and it will take up a large amount of motherboard area, and it is impossible to set the image in real time when collecting images. Mode of operation (deinterlacing, color space conversion, etc.). Is there a way to save hardware cost and motherboard area and transplant various video operation operators to FPGA to process and collect the current transmission video stream in real time to solve the dilemma faced by the existing technology. Contents of the invention [0003] The technical problem to be solved by the present inven...
