Abstract
PURPOSE:To prevent an overlock of error and erroneous correction at the decoding of the next stage, by adding the pointer representing error at the decoding of the 1st stage and discriminating the status of the 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, and the decoding of the next stage to the 1st error correction block is made after that. Further, at the decoding of the 1st stage, the error up to K words in the 2nd error correction block is made and the pointer representing the presence of error is added, and the pointer for all the words in the block including the words in error exceeding K words is regarded as error, and at the decoding of the next stage, the error correction is made by using the error syndrome and pointer operated from a plurality of words included in the 1st error correction block.
