The LED full-color synchronous video control system is mainly composed of the Video controller and Scan controller. The data from computer standard DVI display card are input to the Video controller and then transmitted to scan controller through standard net cable. The Scan controller will send the grey-scale data to the display drive circuit. The Video controller has two signal output ports, and each port can connect a set of Scan controllers. A standard net cable transmit ability is so super that a control system can mostly transmit 1024 X 768 pixels within max distance of 100m.
