◐Modular plug-in card chassis, four-way board design, can be configured with 2 input signal cards and 2 output signal cards, maximum input channels: 8 channels, maximum output channels: 8 channels; 

◐Using FPGA architecture, internal self-built core computing mechanism, no embedded operating system, full digital switching, each signal is transmitted by a separate dedicated channel, and all input and output card signals can be seamlessly real-time regardless of signal format Switch ◐ Support common audio and video signals: HDMI, SDI, DVI, VGA, CVBS, YUV, YC, YPbPr, S-Video and other signals, mix and match to form audio and video switching transmission system; 

◐ With frequency doubling and frequency doubling function, the image signal can be zoomed and enhanced by frequency doubling, and the signals with different resolutions can be processed together to output the signals with the same resolution; 

◐ Output terminal adaptive adjustment, support command adjustment, adapt to different resolution display terminals; 

◐ Use 3Pin Phoenix head independent audio interface, support audio and video switching and audio separation;
