ABSTRACT:
In an error correcting system, an error correcting unit stores a subframe data sequentially and circularly in first to third subframe memories. The subframe data is supplied continuously and is subjected to a first row direction error detecting and correcting process. The error correcting unit performs a column direction error detecting and correcting process to first and second subframe data and then performs a second row direction error detecting and correcting process to a part of the first subframe data, while the first row direction error detecting and correcting process is performed to a third subframe data to store in the third subframe memory. Also, the error correcting unit performs the second row direction error detecting and correcting process to a remaining part of the first subframe data and the second subframe data, while the first row direction error detecting and correcting process is performed to a fourth subframe data to store in the first subframe memory from a head location.
