Abstract
A method for and an apparatus for correcting errors of compressed digital data, using a dual decoding system for correcting errors generated at the data by adding parity bits having an error correction capability for K symbols to the data fields of the data. Errors of up to K are corrected by the C.sub.1 field- and C.sub.2 field-decodings. After the error correction, a determination is made about the presence of errors in the corrected data so that an erroneous detection and an erroneous correction of errors are prevented, thereby minimizing an influence by an error propagation generated upon the extension of compressed data. The present invention achieves an improvement in error correcting capability for compressed digital image data.
