ABSTRACT:
Method and apparatus for detecting and correcting code errors in processing a digital signal such as a digital audio signal are disclosed. An error word correcting parity word generated from a plurality of data words is added to the plurality of data words to form a first frame, and the data words and the parity word of a plurality of different first frames are distributed in a second frame and a plurality of additional parity words for detecting and correcting error words in the second frame are added to the second frame to form a Reed-Solomon code. The code errors are detected and corrected using this code. A code error rate counter is provided, and when an output of the code error counter exceeds a predetermined count, the code error correction is inhibited for a predetermined time period or until the code error rate reaches a second predetermined code error rate.
