ABSTRACT:
Disclosed is method of correcting code errors included in digital data that are structured in unit of frames, using first and second series of parity data. The method includes computing a first group of syndromes for the digital data using the first series of parity data. Then, a number of code errors included in the digital data is primarily decided based on the first group of syndromes, and the number of code errors included in the digital data is monitored in a frame by frame manner. In addition, the method includes primarily correcting at least one code error using the first group of syndromes and affixing an error flag to the digital data based on a result of monitoring the number of code errors. Then, a second group of syndromes for the digital data is generated using the second series of parity data. The method further includes secondarily deciding a number of code errors included in the digital data based on the second group of syndromes and the error flag, and further secondarily correcting at least one code error using the second group of syndromes.
