A decoding device and method for a data stream that represents a user signal and makes up multi-symbol words that are protected against burst errors. In case of a discontinuity, a FIFO jump may occur in the decoding device. Subsequently, de-interleaving may occur, and this will cause the multi-symbol words to be made up from symbols which occur before and after the discontinuity. If this is the case, within such words, the minority symbols are flagged. If too many words have an excessive number of flags, error correction will fail. If so, an error concealment operation occurs, but the number of such concealments is kept minimum. This will decrease the subjective quality of the user signal by only a minimum amount.
