摘要：An error correction apparatus is disclosed for use in erasure correction anderror correction in transmission paths of devices such as optical disk devices, upon receiptof input data of various formats. The apparatus has a select signal generating circuit forgenerating, in response to the format of the input data, a select signal corresponding tothe format of the input data. Also taught is an erasure correction and error correctioncircuit for conducting error correction which includes erasure correction; and acontrolling circuit for controlling the erasure correction and error correction inaccordance with the select signal so as to conduct correction in conformity with theformat of the input data. Thus, erasure correction and error correction can be conducted,regardless of format of the input data.
