摘要： In order to code a digital signal, a simplified version of the digital signal is determined, containing only some of the information contained in the digital signal. The simplified version is coded by means of a predetermined single coding technique. This simplified version is subtracted from the digital signal, so as to obtain a residual signal. From each block of the simplified version, there is selected, for each corresponding block of the residual signal, a coding technique amongst a predetermined number M of coding techniques Ci, where i is an integer between 1 and M. Each block of the residual signal is coded by means of the previously selected coding technique.

摘要： In order to code a digital signal, it is decomposed (20) into several subsignals; each subsignal is coded (38) by means of a coding technique taken from amongst M coding techniques Ci; and the stream of coded bits thus produced is entered (40) 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 (48); 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 (52) 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.

摘要： A method is provided for encoding an image represented by a sequence of symbols. The method includes the following steps: defining subsequences within the sequence; and going through the subsequences applying the following sub-steps for a routine subsequence: determining an adjacent routine encoded group including two previously encoded subsequences, one of which belongs to an adjacent encoded group associated with a subsequence that is separate from the routine subsequence; initializing a routine probability of occurrence of a symbol, taking into account two known probabilities of occurrence of the symbol, relating to two previously encoded subsequences of the adjacent routine encoded group; the consecutive entropic encoding of the symbols, and updating the routine probability of occurrence; and storing the routine probability of occurrence after encoding the last symbol.
