Error correction code block generating method and apparatus and optical storage medium containing error correction code block |
摘要 |
An apparatus, method, and an optical storage medium to generate an error correction block include a data block generation unit processing digital data on a byte-by-byte basis and arranging the processed digital data from 0<SUP>th </SUP>to (N-1)<SUP>th </SUP>columns and from 0<SUP>th </SUP>to (M-1)<SUP>th </SUP>rows to form (MxN) data blocks. A matrix block generation unit arranges the (MxN) data blocks in K rows according to a data transmission sequence to form a matrix block. A first codeword generation unit adds a first error correction check word of 2xK bytes to each of N columns to form a first codeword of ((KxM)+2xK) bytes. A second codeword generation unit adds a second error correction check word of P bytes to each of ((KxM)+2xK) rows to form a second codeword of (N+P) bytes.
