The invention discloses a long-distance transmission method for a high-resolution video image and a background server, and the method comprises the following steps: S1, generating a plurality of mutually complemented second-resolution signals through a first-resolution signal generator, and transmitting the second-resolution signals to a coding node for coding; s2, driving the image display and control system to associate the second resolution signals according to a preset image combination sequence, and storing the second resolution signals to a signal list; and S3, forming a virtual first resolution signal from the second resolution signal through the image display control system, and forming a virtual window for mapping the coordinates and width and height of a real window so as to obtain the windowing position of the second resolution signal on the LED spliced display screen. In the invention, the high-resolution first-resolution signal is transmitted to the LED spliced display screen in the form of the l
