[0003] In the prior art, for long-distance DVI video signal transmission, one method is to adopt DVI cable transmission, and then carry out signal enhancement through a signal booster, because the quality of the cable product has an important influence on the video signal, so the DVI video signal is transmitted after a long period of time. After long-distance transmission, especially after low-quality cable transmission, the signal has been severely deformed. Even if it is enhanced by a signal booster, a good-quality signal cannot be recovered, resulting in signal distortion on the display of the transmission terminal.

The DVI video signal transmission method and device can conduct data recovery on DVI video signals transmitted in the links, ensure the quality of signals transmitted to a terminal display device, and are applied to long-distance transmission.
Description
technical field [0001] The invention relates to video transmission technology, in particular to a DVI video signal transmission method and device. Background technique [0002] Digital Visual Interface (DVI for short) is a standard for video transmission and display introduced by the Digital Display Working Group (DDWG). As liquid crystal displays become mainstream display devices, DVI is widely used. According to the DVI standard formulated by DDWG, its effective transmission distance is 5 meters. However, in actual industrial applications, the situation of long-distance DVI video signal transmission over 5 meters is often encountered. [0003] In the prior art, for long-distance DVI video signal transmission, one method is to adopt DVI cable transmission, and then carry out signal enhancement through a signal booster, because the quality of the cable product has an important influence on the video signal, so the DVI video signal is transmitted after a long period of time....
