Abstract

PURPOSE: To prevent the detection mistake and erroneous correction at the decoding of the next stage, by making the correction limited to one word error at the decoding of the first stage.
CONSTITUTION: The decoding of the 1st stage to the 2nd error correction block is made, and the PCM data series of a plurality of channels and the 1st check word series are delayed with different time for channel. Next, the decoding at the next stage to the 1st error correction block is made and the error correction up to the number of words within K in the 2nd error correction block is corrected and at the error detection the K-words or more, all the words within 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 a plurality of words included in the 1st error correction block to obtain the error location, allowing to correct the error of the words, less than K to discriminate the number and status of the pointer indicating the errors included in the 1st error correction block.
