Abstract
In order to code a digital signal, it is decomposed (,) into several subsignals; each subsignal is coded (,) by means of a coding technique taken from amongst M coding techniques Ci; and the stream of coded bits thus produced is entered (,) in a first part of a file intended to receive the coded digital signal. Then the application, successively to each coded subsignal, of each decoding technique Di associated with the coding technique Ci is simulated (,); and if and only if at least two different decoding techniques are acceptable, within the meaning of a predetermined likelihood criterion, for decoding the same coded subsignal, there is entered (,) in a second part of the file information making it possible to select, during decoding, the decoding technique associated with the coding technique used for coding this subsignal.
