Systems for transmitting and receiving signals of video digital images for links of the “LVDS” type comprise a transmit module, a transmission link and a receive module. The “RGB” video signal comprises the colour and synchronization signals and a clock signal. The “LVDS” video signal transmitted via the transmission link comprises several primary signals, the first primary signal dedicated to the clock signal, the second primary signal comprising the synchronization information, the other primary signals comprising only the colour encoding information. The function of the “LVDS” transmit module is to encode the “RGB” video signal into an “LVDS” video signal and the function of the receive module is to decode the “LVDS” signal into an “RGB” signal. The system comprises the following particular arrangements: the transmission system having a means making it possible to inlay a graphic recognition pattern in the “RGB” video signal; the receive means operating in oversampling and having a test means capable of identifying the synchronization information and the graphic recognition pattern. |
