ABSTRACT:
A method of decoding DVD-format data may include: receiving a demodulated error correction code (ECC) block of DVD-format data; parity-of-inner-code-correcting (PI-correcting) the demodulated ECC block as needed; identifying any errant column within the PI-corrected block which merits PO-correction; and selectively PO-correcting only the errant PI-corrected columns to obtain a decoded version of ECC block.
