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.
