Abstract:
1. A system for transmitting and receiving signals of video digital images of the “RGB” type for links of the “LVDS” type, comprising: at least one transmit module, a transmission link and a receive module; the “RGB” video signal comprising three colour signals corresponding to the colour coding of the pixels of the transmitted images, three synchronization signals and one clock signal; the “LVDS” video signal transmitted via the transmission link comprising at least four primary signals, each primary signal being transmitted over a transmission cable which is dedicated thereto, the first “LVDS” primary signal dedicated to the clock signal, the second “LVDS” primary signal comprising the synchronization information and at least the third and the fourth “LVDS” primary signal comprising only the colour coding information; the “LVDS” transmit module having the function of encoding the “RGB” video signal into an “LVDS” video signal and the receive module having the function of decoding the “line” signal into an “RGB” signal; wherein the transmission system comprises a means making it possible to inlay a graphic recognition pattern in the “RGB” video signal; wherein the receive means operate in oversampling, that is to say at a sampling frequency that is a whole multiple of the frequency of the clock signal; and wherein the receive means comprise test means capable of identifying the synchronization information in the second “LVDS” primary signal and the graphic recognition pattern.
