Other AbstractThe invention relates to an LVDS digital video fault automatic detection system and an implementation method thereof, the system comprises a fault automatic detection module, the fault automatic detection module comprises a video synchronization module, a fault detection module, a main control module, a video generation module and a communication module, a LVDS sending module comprises a first LVDS intersection point switch and an LVDS parallel-serial encoder, a LVDS receiving module comprises a second LVDS intersection point switch and an LVDS serial-parallel decoder, and the implementation method comprises an internal test working mode and a normal working mode. According to the invention, automatic fault detection of the LVDS digital video is realized, and the response capability of thesystem when a fault occurs is enhanced, the added LVDS intersection switch can also compensate the transmission loss of the LVDS signal at the receiving end, the driving capability of the LVDS signalat the sending end is improved, a fault automatic detection module is added and can be realized through a part of programmable logic resources in a digital video processing system, so that the software overhead is relatively low, and the integration degree is relatively high and the transportability is relatively good.
