Abstract: A method for processing a digital signal comprises receiving an output encoded signal (Sd,sc) obtained from an original digital signal (Si) having an initial spatial resolution and an initial bit rate, the output encoded signal having a bitrate lower than the initial bitrate, processing the output encoded signal to obtain a source signal (Sv) having the initial spatial resolution, and dividing (E303) samples of the source signal into at least two subsets of samples, the subsets corresponding respectively to different spatial grids that are arranged so that at least some samples of one subset are interleaved spatially with at least some samples of another said subset. Further, for each said subset, the method comprises determining (E305, E309, E311), for at least one sample of the subset, at least one filter amongst a set of predetermined filters according to a first predetermined criterion and finally inserting (E310) in a side information signal information representative of the filter(s) determined for the samples of the subset concerned. The method is suitable for encoding an original digital signal into an output encoded signal and a side information signal, the original digital signal having an initial resolution and an initial bitrate.
