The invention concerns a digital data compression encoder, characterized in that it comprises: an input for a first data flow (SH), and a second data flow (SL), an encoding module, matching symbols of the first data flow and code words, wherein, for certain symbols, there exist several words, called redundant, corresponding to the same symbol, and a processing module for encoding the symbols of the first data flow based on the correspondence, by selecting among the redundant words, on the basis of at least part of the second data flow. |
