Abstract
An error correction arrangement that contains a Viterbi decoder and an RS decoder to provide inner and outer code decoding, respectively. A score keeper is arranged at the output of the Viterbi decoder to form a score for a decoded byte to indicate the number of error bits in the byte. A tie breaker is provided to compare the score with a preset threshold level. If the score is higher than the threshold level, the corresponding error byte is replaced with an erasure supplied to the RS decoder.
