    摘要: The present invention relates to a method for encoding and decoding an error correction block, and more particularly to a method for encoding and decoding an error correction block useful for a high-density optical disc. When an error correction block is encoded, a user data block is generated and parity outer information for a vertical data stream within the user data block is generated. Then, parity inner information is generated using an eraser detection code contained in a horizontal data stream or at least one of a syndrome check parity, a sync byte and an indicator flag is generated within the user data block so that an eraser can be declared in the horizontal data stream at a predetermined internal. On the other hand, when the error correction block is decoded, a determination is made as to whether errors are detected from the eraser detection code, the syndrome check parity, etc., and erasers are declared according to a result of the determination.

    摘要: A method for encoding multiword information by wordwise interleaving and wordwise error protection with error locative clues derived from synchronizing channel bit groups and directed to target words, a method for decoding such information, a device for encoding and/or decoding such information, and a carrier provided with such information. Multiword information is encoded as based on multibit symbols disposed in relative contiguity with respect to a medium. It has wordwise interleaving, wordwise error protection code facilities and error locative clues across words of a multiword group. These originate in synchronizing channel bit groups and target data words.

    摘要: A decoder including a decode module, a matrix module, and a marking module. The decode module receives data and performs a first decoding iteration to decode the data. The first decoding iteration includes generating a first matrix having a first byte. The matrix module generates a second matrix based on the first matrix. The second matrix includes the first and second bytes. The second byte is adjacent and sequentially prior or subsequent to the first byte. The marking module: determines whether the first byte has been correctly decoded; based on determining whether the first byte has been correctly decoded, determines a status of the second byte; and based on the status of the second byte, marks the first byte as an erasure. The decode module, based on the second byte being marked as an erasure, corrects the second byte during the second decoding iteration.

    摘要: The error correction capability of block codes can be doubled if error locations are known. Prior art approaches for error location detection always involve adding dedicated redundant data which then are evaluated to yield error location information. The present invention proposes and describes how error location information in the form of clues is derived from given DC control bits that are anyway present in a data stream.

    摘要: In a decoding system and method for a high-density recording medium, a high protective codeword decoder decodes a burst indicator subcode (BIS) while a low protective codeword decoder decodes a long distance code, so as to eliminate the waiting time required for completely decoding all burst indicator subcodes (BISs) and starting the long-distance code (LDC) decoding. In addition, a first memory having a high access speed is implemented to store the BISs and corresponding BIS erasure indicators, and the access to a second memory have a lower access speed relative to the first memory is relatively reduced such that the bandwidth can be effectively used to thereby increase the decoding efficiency on the high-density recording medium.
