Apparatus and method for decoding data

摘要

Decoding apparatus and method set interpolation flags in units smaller than an ECC block. The PI1 flag indicating an error on a row-by-row basis is generated for the first error correction result, while the PI2 flag also indicating an error on a row-by-row basis is generated for the second error correction result in the ECC block. The PO flag indicating an error on a column-by-column basis is further generated for the error correction result in the ECC block. Following these processing operations, the PI1, PI2 and PO flags are used for generating the interpolation flags. <IMAGE>
