ABSTRACT:
An error correcting apparatus and method of a digital processing system. The error correcting apparatus of the digital processing system includes a demodulator for demodulating channel data to source data and generating an error flag when an error occurs during demodulation, a synchronous detector for receiving the error flag and demodulation data generated from the demodulator and detecting a synchronizing signal to distinguish data by a unit of code which can correct an error, a first decoder for decoding the demodulation data and the error flag by a unit of row by the synchronizing signal to correct an error and an erasure, and a second decoder for decoding the demodulation data and the error flag by a unit of column by the synchronizing signal to correct an error and an erasure.
