    摘要: A method for decoding multiword information comprises multiple steps. In step (a), a multiword information cluster, e.g., ECC, including high protective codewords, e.g., BIS, and low protective codewords, e.g., LDC, is provided. In step (b), the high and low protective codewords are stored into a first memory, e.g., DRAM. In step (c), the high protective codewords are decoded to generate high protective word erasure indicators showing whether decoding errors occur. In step (d), the high protective word erasure indicators are stored into a second memory, e.g., SRAM. In step (e), the low protective codewords are decoded. In the meanwhile, an erasure bit for a low protective codeword is marked by finding high protective codewords close to the low protective codeword in the multiword information cluster and looking up the high protective word erasure indicators of the high protective codewords close to the low protective codeword.

    摘要: The present invention provides an error correction method that is used in full response read channels. This method includes the steps of: obtaining a read signal from a storage medium and converting the read signal into channel bits that are recorded in the storage medium, such as a DVD disk, in the NRZI format; and using the Viterbi detector to determine whether bit state transitions in the channel bits occur within a predetermined run-lengths of the RLL codes. If transitions occur within the predetermined run-lengths, then the values of the bits with state transitions are corrected.
