ABSTRACT:
A digital signal decoding apparatus for preventing errors which cannot be corrected sufficiently by error correction from reflecting on a decoded signal. An uncorrectable error part of a digital signal or a data part including the error part is replaced with a special code including a synchronous code, and is output to decoding means. Because the decoding means capable of identifying the synchronous code can also identify the special code, a proper error processing can be executed by confirming the presence of errors at the time of decoding. Therefore, by using the decoding means, it is possible to prevent errors which cannot be sufficiently corrected from reflecting on a decoded signal.
