Using the leading edge fusion and image special effects processing technology at home and abroad, it can not only be spliced into a single logic screen with ultra-high resolution, and there is no seam in the middle, the sum of the resolution of all display units that make up the large screen system, and at the same time, it can make the window change or mode switch, and can produce the effect of characteristic display. The HD Fusion Processor can handle real-time input from multiple formats of sources, supporting high-resolution signals from analog to digital, from 1024x768 to 1920x1080. The built-in multi-viewer graphics splicing processor and fusion tape generation device integrate video multi-window processing technology and edge fusion technology, and perfectly realize the functions of video multi-window display, edge blending, chromatic aberration correction, multi-channel signal source selection, automatic input signal adjustment and free call of pre-stored scenes on one controller. It is widely used in: exhibition centers, venues, airports, shopping malls, advertising, demonstration centers, design, simulation centers, military operations, communication command, training centers and other places.
