Method for decoding a stream (F) representative of at least one coded image made up of at least two tiles, one tile being made up of a plurality of blocks of at least two rows of the image to be decoded (TU 1 , TU 2 ,..., TU j , ...TU N ), which blocks are adjacent in pairs having been grouped then coded consecutively, said blocks being able to contain symbols belonging to a predetermined set of symbols, said at least two tiles being separated by a vertical boundary, comprising the steps of: - identifying (D1), in said stream, at least two data substreams (SF 1 , SF 2 , ..., SF j , ..., SF N ) respectively corresponding to said at least two tiles, one tile being associated with one substream, - decoding said at least two tiles of blocks by means of an entropic decoding module, by reading, in said identified substreams, digital information associated with the symbols of each block of the corresponding tile, said decoding step comprising, for the first block to be decoded of the image, a substep (D23) of initializing state variables of said entropic decoding module, said decoding method being characterized in that it comprises the following steps during the decoding of the blocks of a row of the image, at each vertical boundary: - in the case (D25, O) in which the current block of said row is a block previously decoded and identified as being the last block of a row of one of said tiles, it further comprises: - a step of reinitializing (D26) the state variables of said entropic coding module, and - a step of storing a position of the read pointer of said substream associated with said tile in a memory; - in the case (D23, O) in which the current block of said row is a block identified as being the first block of a row of one of said tiles, it further comprises a step of recovering (D241) a position of the read pointer of said substream associated with said tile from said memory. - identifying (D1), in said stream, at least two data substreams (SF 1 , SF 2 , ..., SF j , ..., SF N ) respectively corresponding to said at least two tiles, one tile being associated with one substream, - decoding said at least two tiles of blocks by means of an entropic decoding module, by reading, in said identified substreams, digital information associated with the symbols of each block of the corresponding tile, said decoding step comprising, for the first block to be decoded of the image, a substep (D23) of initializing state variables of said entropic decoding module, - in the case (D25, O) in which the current block of said row is a block previously decoded and identified as being the last block of a row of one of said tiles, it further comprises: - a step of reinitializing (D26) the state variables of said entropic coding module, and - a step of storing a position of the read pointer of said substream associated with said tile in a memory; - in the case (D23, O) in which the current block of said row is a block identified as being the first block of a row of one of said tiles, it further comprises a step of recovering (D241) a position of the read pointer of said substream associated with said tile from said memory. - a step of reinitializing (D26) the state variables of said entropic coding module, and - a step of storing a position of the read pointer of said substream associated with said tile in a memory; - in the case (D23, O) in which the current block of said row is a block identified as being the first block of a row of one of said tiles, it further comprises a step of recovering (D241) a position of the read pointer of said substream associated with said tile from said memory. <EOS>
