摘要： A circuit which recovers a synchronization code, and a method thereof. Where a synchronization code is not detected from an incoming bitstream, a plurality of synchronization code recovery candidate patterns are compared with an original synchronization pattern, and location data to produce an optimal synchronization pattern is determined and generated on the basis of a result of the comparison. The synchronization code is recovered to a location corresponding to the location data. Alternatively, where a synchronization code is not detected from an incoming bitstream, a plurality of synchronization code recovery candidate patterns are error-corrected, and location data to produce an optimal synchronization pattern is determined and generated on the basis of a result of the error correction. The synchronization code is recovered to a location corresponding to the location data. Accordingly, a damaged synchronization code can be recovered by inserting a synchronization code to a more accurate location, further increasing the reliability of data.

摘要： An apparatus, method, and an optical storage medium to generate an error correction block include a data block generation unit processing digital data on a byte-by-byte basis and arranging the processed digital data from 0th to (N−1)th columns and from 0th to (M−1)th rows to form (M×N) data blocks. A matrix block generation unit arranges the (M×N) data blocks in K rows according to a data transmission sequence to form a matrix block. A first codeword generation unit adds a first error correction check word of 2×K bytes to each of N columns to form a first codeword of ((K×M)+2×K) bytes. A second codeword generation unit adds a second error correction check word of P bytes to each of ((K×M)+2×K) rows to form a second codeword of (N+P) bytes.

摘要： A decoding method and an apparatus operate by performing error correction on code words of an error correcting code block in one direction selected from a row direction and a column direction, indicating in error flags the remaining code words except at least some code words from code words having uncorrectable errors, and performing error correction on code words in the other direction based on the error flags. Accordingly, errors that have been conventionally considered as being uncorrectable may now be corrected.
