Abstract: 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.

Abstract: The field of the invention is that of serial digital data transmissions. Such digital data is, in particular, of video type. In certain types of transmission, the links used cannot pass direct current. Such is the case in particular with the so-called “AC-coupled” links used in aeronautics for transferring video signals between computers. In this case, it becomes essential to transmit binary words comprising, if possible, similar quantities of zeroes and ones. The subject of the invention is an encoder or a decoder of 9-bit binary words into 10-bit binary words, said 10-bit binary words being designed to be transmitted over links that cannot pass direct current, said binary words comprising between four ones and six ones regardless of the initial 9-bit binary word.
