Method and system for converting LVDS video signal to DP video signal

摘要

The present invention relates to a method for converting an LVDS video signal into a DP video signal, the method comprising: receiving and demodulating an LVDS video signal to generate demodulated data and an LVDS pixel clock in LVDS parallel; Generating LVDS image source data and an LVDS image source synchronization signal by performing image decoding on the demodulated data in parallel with the LVDS image decoding control signal; Generating the corresponding RGB image pixel clock by converting the LVDS image source data and the LVDS image source synchronization signal into an RGB image signal according to an LVDS image conversion control signal and performing a frequency multiplication operation corresponding to the LVDS pixel clock; ; And converting the RGB image signal into a DP image signal after a DP image conversion start command is received. The present invention can detect the quality of LVDS video signal and the validity of image data, has high reliability, excludes false judgment, and features simple operation, high detection efficiency and low cost.
