Abstract
A method relates to the of determining a data configuration of a digital signal of an image, the signal having undergone at least one spatio-frequential transformation in at least one resolution level. The method includes determining and configuring steps. The determining step determines at least one minimum rate reduction (D) as a proportion of the total data rate of at least one resolution level of the signal, as a function of a quality mode desired for the signal. The configuring step configures the data of the signal in at least one quality layer defined for at least one resolution level of the signal such that the at least one quality layer so defined corresponds to a given visual quality of the signal, the data making up that at least one quality layer being obtained by a reduction (D) of the total rate of the data of the at least one resolution level of the signal which is greater than or equal to the minimum reduction (D).
