Problems solved by technology

[0002] In the LED display control system, the video processor and the display controller are connected through the HDMI interface or the DVI interface. However, the transmission distance of the video transmission line of these interfaces is very short. When the distance is long, the video transmission line cannot be used to transmit the video source. For example, in most rental sites, the display controller is usually placed behind the LED display, and the video processor is placed in the control room. The control room and the LED display are separated. At a distance of tens of meters, there is no way for the video transmission line to transmit the video source at this distance
[0003] In the existing related technology, the video processor and the display controller are connected through an HDMI / DVI to optical fiber adapter to realize long-distance transmission. Two adapters need to be added, which reduces system stability and increases costs
