This introduction will begin from LINSN LED display control system. And we will make the introduction of both hardware and software parts.
Please find below photos of sending card and receiving card. There will be one sending card installed in the controller PC, and one receiving card installed in each cabinet, which consists of the led display panels.
The DVI signal comes from the sending card in PC and transferred to the receiving cards in display body. And if other kind signal for example from TV, Camera or any other devices be input, a small device called Video Processor will then be adopted. In this way, all the signal will first come to the video processor, and then transferred to the LED display body.
It is the same way with ZDEC.
Please email us to sbright@sbright.net.cn  for the LINSN control system software manual. And you will learn the software function by reading the user manual in detail.
For the reason of lower price and good software function, LINSN is chosen by most led display manufactures. But the advantage of ZDEC is the higher refresh frequency. If one display is used much in TV broadcast and other similar application, ZDEC will be the choice. And sometimes, the hardware part of ZDEC controller is integrated with the software part of LINSN control system.
