Problems solved by technology
Limited by the bandwidth and power consumption of the PC motherboard, the PC processor cannot receive a large number of input and output signals. If you want to achieve large-scale splicing, you must configure high-cost industrial control equipment, so it is only suitable for small-scale splicing occasions.
At the same time, due to the limited processing speed of the CPU, the real-time performance of multi-channel video transmission and high-resolution display cannot be guaranteed.
Moreover, because the PC processor has an operating system, the stability and security are low, and it is easy to be infected with viruses. It takes a long time to start the system, and even crashes or cannot be started.

Embodiment Construction
[0026] Such as figure 1 , figure 2 , image 3 Shown, a kind of video processing system based on FPGA technology described in the present invention has included a plurality of video signal input boards 1, 2, 3...N at the video input end; Output boards 1, 2, 3...N. The video signal input by the external device is received by the video signal input board, and then output to the peripheral display by the video signal output board through the output matching of the signal exchange substrate. The above-mentioned video signal input board, signal exchange board and video signal output board are respectively connected to the control board through the IIC bus, and the control board is responsible for controlling the signal processing and control of the above-mentioned functional boards.
[0027] The pre-deserializer at the input end of the video signal input board receives the original video signal input from the outside, and then deserializes the original video signal into a parall...

The invention discloses an FPGA technology based video processing system. The system comprises a video signal input board that packages a deserialized video signal through an input-end FPGA hardware circuit and transmits the signal to a signal exchange base board, the signal exchange base board that transmits a video signal packaged by a video signal input board to a video signal output board in a serial mode, the video signal output board that performs cutting or zooming on a video signal of a received video through an output-end FPGA hardware circuit, and a control board that controls the coordinated transmission of the signals. The system has the advantages that the software image processing is replaced with the FPGA hardware circuit, and the quickness and editability are achieved; moreover, the software problems in multiple aspects of downtime, viruses and the like of an operation system are completely avoided; the parallel signal processing is adopted, so that signal channels can be added or deleted at will in multiple input and output states, and the expandability is very high; and regardless of image stitching of paths , a high-price industrial personal computer does not need to be used, so that the cost is reduced.
Description
technical field [0001] The invention relates to a video processing system, in particular to a video processing system based on FPGA technology. Background technique [0002] The large-screen splicing control system currently on the market is a splicing processing system of computer software technology. This processor system is based on PCI or PCI-E plug-in card architecture, adopts the principle of industrial computer, and uses multiple PCI computer motherboards. Some PCI slots are PCI video capture cards, and some PCI slots are PCI video output cards. The CPU and GPU are used between the input card and the output card to build a data calculation and video processing center, so as to build an industrial splicing processing device. Its video image processing principle is to divide the selected input video signal into M*N sub-video signals after calculation by CPU and GPU (graphics processor), and then perform arbitrary scaling processing on each sub-video signal, and then se...
