Abstract
The invention relates to a digital signal reproducing apparatus to which continuous blocks of input data are supplied, each block consisting of a PCM signal which was error correction coded and additional codes which were subjected to error detection or error correction coding processes. The error pointers are set independently of the result of the error correction of the PCM signal on the basis of the decoding state of the decoder for decoding the additional codes using the error detection code or error correction code.
