<p>Method of correcting a message to be transmitted between a sending apparatus and a receiving apparatus distributed on a transmission line powered by the mains, the said line being the seat of interference affecting the transmission of the said message. According to the invention, the said method of correction includes the following steps: a) sending by the sending apparatus, at a first transmission speed (V1), of the message with a request for acknowledgement, b) in the absence of acknowledgement, sending by the sending apparatus, at another transmission speed, of a correction message synchronous with the frequency of the mains, with a request for acknowledgement, and containing a correction algorithm, then, the correction algorithm being equal to the identity algorithm, c) in the presence of an acknowledgement of the correction message, sending by the sending apparatus, at the said other speed, of the message with request for acknowledgement, d) in the absence of an acknowledgement of the correction message, sending by the sending apparatus, with yet another transmission configuration, of the message with request for acknowledgement. <IMAGE></p> |
