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

摘要

The present invention relates to a method for converting an LVDS image signal into a DP image signal, the method comprising: receiving and demodulating an LVDS image signal to generate LVDS parallel data and LVDS pixel clock; Performing image decoding on data demodulated in parallel with the LVDS in accordance with an LVDS image decoding control signal to generate LVDS image source data and LVDS image source synchronizing signal; Converting the LVDS video source data and the LVDS video source sync signal into an RGB video signal according to an LVDS video conversion control signal and performing a frequency multiplication operation corresponding to the LVDS pixel clock to generate a corresponding RGB video pixel clock ; And converting the RGB image signal into a DP image signal after the DP image conversion start command is received. The present invention is capable of detecting the quality of LVDS video signals and the validity of image data, has high reliability, eliminates false judgments, and features simple operation, high detection efficiency and low cost.
