ABSTRACT:
The invention relates to a method of transforming a digital signal for it to be transmitted, the signal being decomposed into several regions each containing digital data, the signal comprising header data specific to each region and which comprise at least one part representing the amplitude of the data of the region considered, wherein the method comprises a step of modifying, among the header data specific to at least one region of the signal, the part of the header data representing the amplitude of the data of the region considered.
