PROBLEM TO BE SOLVED: To provide methods and apparatuses for correcting errors in a data stream. SOLUTION: In one aspect, an error correction process is operable to correct errors in at least two separate types of data streams, each of which utilizes a distinct error correction scheme. The error correction process utilizes Reed-Solomon code and Error Detection Code (EDC) in combination for error correction. The process comprises using a Reed-Solomon code to identify errors in a plurality of data blocks and attempting to correct the errors. An EDC map is then generated, wherein the EDC map identifies the location of the errors within the corresponding data blocks which includes errors that are not corrected by the Reed-Solomon code.
