    摘要: Receivers for recovering ancillary data from parallel concatenated convolutional coding. (PCCC) imbedded in digital television (DTV) signals can utilize the non-systematic (207, 187) Reed-Solomon (RS) codewords included in the DTV signals to facilitate DTV receivers already in the field to continue being able to receive main-service transmissions. Such a receiver attempts to decode each non-systematic (207, 187) RS codeword in a time slot selected for reception. If such RS decoding is successful, indication of such success is used to verify the correctness of bits of the ancillary data or correct them when turbo decoding the PCCC encoding ancillary data in the time slot selected for reception. The updating of ancillary data bits during cycles of turbo decoding updates the non-systematic (207, 187) RS codewords in the time slot selected for reception, increasing the likelihood of RS decoding of those RS codewords being successful during subsequent cycles of turbo decoding. If all the non-systematic (207, 187) RS codewords in the time slot selected for reception are successfully decoded before reaching a prescribed maximum number of cycles of turbo decoding, turbo decoding can be discontinued early to conserve operating power.

    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: A decoding system includes a decoder, a first module and a second module. The decoder is configured to receive data read from an optical storage medium and perform a first decoding iteration and a second decoding iteration to decode the data. The first decoding iteration includes generating a resultant matrix. The first module is configured to, based on first decoding statuses of multiple bytes in the resultant matrix, determine second decoding statuses of bytes proximate to failed bytes of a feedback matrix. The feedback matrix is generated based on the resultant matrix. The first module is configured to mark selected ones of the failed bytes as erasures based on the second decoding statuses. The second module is configured to correct one or more of the bytes marked as erasures during the second decoding iteration.

    摘要: A recording medium for storing a data stream is comprised of first error correcting codes obtained by encoding first information, second error correcting codes obtained by encoding second information, and synchronization signals. In the data stream, the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes. The second error correcting codes have the same number of corrections as the first error correcting codes. A code length of the second error correcting codes is shorter than a code length of the first error correcting codes.

    摘要: The present invention relates to a method of embedding an additional layer of error correction into an error correcting code such as a product code in a DVD or a picket code in a DVR, wherein information is encoded into code words of said code and wherein a number of code words are arranged in the columns of code block. In order to provide an additional layer of error correction that can be easily implemented without losing compatibility improving the error correction capabilities a method is proposed comprising the steps of: reducing the length of each row of said code block by adding row symbols together according to a predetermined adding rule resulting in a reduced code block, encoding the shortened rows of said reduced code block using a horizontal error correcting code to obtain horizontal parities, embedding said horizontal parities as additional layer in said error correcting code.
