<p>A data error correcting method determines the range of data error correction to minimize the elimination of error-free data by minimizing the range for correcting data errors generated during decoding of received data. The steps include (a) detecting an error in data during forward decoding; (b) determining the location of a forward error block which corresponds the location of the first predetermined unit data block including error data detected in step (a); (c) stopping forward decoding and detecting an error in data while decoding the data in a reverse direction, if an error is detected in said step (a); (d) determining the location of a reverse error block which corresponds to the location of the data block including the error detected in said step (c); and (e) determining the data between said forward and backward error blocks, inclusive, as an error correction range. Therefore, high-quality reproduction can be achieved by minimizing an error correction range by means of reverse decoding and thus reducing elimination of error-free data, eg for multimedia video data.</p> |
