ABSTRACT:
A device is described for correcting and concealing a data stream which is block-wise provided with redundancy. The redundancy has an error-correction capability per block. The blocks are received from a medium in a systematically distributed manner. After regrouping, error-signalling is formed per block by way of the error-correction code. For a number of successive blocks the total number of expected errors is compared with a threshold which lies within the error-correction capability of the code. When this threshold is exceeded, concealing takes place, even when the total maximum correction capability of the code has not yet been fully utilized.
