Abstract
The present invention provides an error correction apparatus and an error correction method, which does not execute unnecessary syndrome operation and operation processing subsequent to the syndrome operation. A format interface judges whether an uncorrectable error is included in parallel with demodulation of received data, and outputs an error correction incapability detection signal when the uncorrectable error is included. The error correction circuit executes decoding of the error correction, including syndrome operation, for demodulated data from the format interface , suspends the syndrome operation when the error correction incapability detection signal is input, and terminates the error correction.
