Abstract

The invention relates to an error-correction method for use in a process of decoding cross-interleaved Reed-Solomon code (CIRC) that corrects errors in data stored as C1 code words and C2 code words in a memory with several locations, each of said locations containing a data byte of said data, and an apparatus performing said method. The new method implies specific regulations for defining which data words are to be used for C1 and C2 decoding and for the processing order. The system memory for a deinterleaver implementation can be of a smaller size as compared to conventional memories. In addition, only a single CIRC decoder needs to be used for performing the process of decoding cross-interleaved Reed-Solomon code.
