<p>The invention relates to a decoding device for a data stream that represents a user signal and consists of multi-symbol words that are protected against burst errors. In case of a contingency situation a FIFO jump may occur. Subsequently, time-interleaving may occur and this will cause multi-symbol words to be built up from both symbols before, and symbols behind the discontinuity. If this is the case, within such word the minority symbols are flagged beforehand, so that many words will have an excessive number of flags causing the correction to fail. If so, an error concealment operation ensues, but the number of such concealments is kept about minimum. This will decrease the subjective quality of the user signal by only a minimum amount.</p> |
