Abstract

PURPOSE:To prevent an overlock of error and an erroneous correction, by making correction through the discrimination of status of error pointer at the decoding of the next stage. CONSTITUTION:The decoding of the 1st stage is made to the 2nd error correction block, and the PCM data series of a plurality of channels and the 1st check word series are delayed for different time, for the decoding of the next stage to the 1st error correction block, and at the decoding of the 1st stage, the error having the number of words less than K in the 2nd error correction block is corrected, and at the detection of error having the word number exceeding the number of words, all the words in the block are regarded including the error, and the error pointer is added to each word. At the decoding of the next stage, the error syndrome is operated from the word included in the 1st error correction block and the error location Ei is obtained, allowing to correct the error up to K words, and the number of error pointers and status included in the 1st error correction block are discriminated at this correction process.
