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

摘要

The present invention relates to a method for converting an LVDS video signal into a DP video signal. The method comprises: receiving and demodulating an LVDS video signal to generate LVDS parallelly modulated data and an LVDS pixel clock; performing video decoding on the LVDS parallelly modulated data according to an LVDS video decoding control signal, to generate LVDS video source data and an LVDS video source synchronization signal; converting the LVDS video source data and the LVDS video source synchronization signal into an RGB video signal according to the LVDS video transformation control signal, and performing a corresponding frequency multiplication operation on the LVDS pixel clock to generate a corresponding RGB video pixel clock; and converting the RGB video signal into a DP video signal after a DP video conversion starting command is received. The present invention can detect the quality of an LVDS video signal and the validity of image data, and features high reliability, being free of erroneous judgments, simple operation, high detection efficiency, and low costs.
