 Overview 

 

 

 
The Video Wall Processor is a high performance video processing workstation with pure 
hardware architecture for spectacular video wall displaying which can be employed in fields 
including education and research, government announcement, information publishing, 
exhibition and show, controlling and commanding center, security monitoring, etc. 
Advanced image processing technologies such as high definition video signal collecting, 
real time and high resolution digital image processing ,and advanced three-dimensional 
digital filtering are integrated in video-wall processor. Moreover, it also employs large-
capacity, high-speed FPGA and CrossPoint switch to ensure the real-time processing of all 
input signal and the consistency of the data, leading to no image delay, discretization, frame 
loss, which guarantee excellent video displaying. 
 
Video-wall processor is compatible with a wide variety of input signal formats, 
including ,CVBS,YPbPr, VGA, DVI, Dual-link DVI, HDMI, SDI, twisted pair signal,
