The invention discloses a video acquisition and display switching method and device, and the method comprises the steps that a power module carries out the external power supply of the device, and opens the device; the device is started, and all video signals of each computer host are sent to the Hisilicon video processing chip after being digitally processed by the FPGA chip; a video processing chip of the device realizes communication with upper computer software through a network module, and the device receives switching control information of the upper computer software on an input video interface to an output video interface; the video processing chip of the device processes the digital video signal sent by the corresponding FPGA according to the switching control information of the upper computer, sends the digital video signal to the video output interface, and finally displays the digital video signal on the computer display. The domestic autonomous controllable degree of the device is improved. The problem of high dependence of conventional products on imported chips is solved, and the information security is improved at the same time.

    本发明公开了一种视频采集与切换显示的方法及装置,包括以下步骤:电源模块对装置进行外部供电,并将装置打开;装置启动,每路计算机主机的视频信号通过FPGA芯片数字化处理之后全部送到海思视频处理芯片;装置的视频处理芯片通过网络模块实现与上位机软件通信,装置接受上位机软件对输入视频到输出视频接口的切换控制信息;装置的视频处理芯片根据上位机切换控制信息,将对应FPGA的发送的数字视频信号进行处理之后,送到视频输出接口,最后到计算机显示器显示。本发明提高了该类装置的国产自主可控程度。解决了常规该类产品对进口芯片的依赖高的问题,同时提高了信息安全。
