摘要： A device and method for block code error correction. The device includes a block code input unit, an erasing address table, an error table and a decoder. The block code input unit is used to input a block code. The erasing address table and the error table have a plurality of erasing entities and error entities in rows and columns, respectively. The decoder decodes the block code in a row direction based on the erasing address table to find data errors on rows and update the error table, and updates the erasing address table in the row direction according to a first determination principle. Next, the decoder decodes the block code in a column direction based on the erasing address table to find data errors on columns and update the error table, and updates the erasing address table in the column direction according to a second determination principle.

摘要： Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, and mechanisms, for use in protecting groups of data words. One embodiment manipulates these data words to generate a resultant data word and an error correction code thereon for use in identifying a position of a bit error, with error detection codes used to identify which data word actually has the bit error. One embodiment retrieves a stored particular data word and its error detection code from memory or other storage. If an error is detected, the other data words in the group corresponding to the error correction code are acquired and are manipulated to produce a new resultant data word. The error correction code and the new resultant data word are used to identify the position of the bit error, with a corresponding bit position corrected in the particular data word.

摘要： An iterative method of correcting errors in a data block. Bad bytes are first identified using information derived from an 8 B/10 B decoding of the data block. Within each identified bad byte, suspect bits are subsequently identified using information derived from parity decoding of a row of the data block. Each suspect bit is then classified as either a confirmed error bit or an unconfirmed error bit using information derived from parity decoding of a column of the data block in which the suspect bit is located. Confirmed error bits are then corrected, the parity bits corresponding to the confirmed error bit reset, and the bad byte cleared. The process is then repeated if one or more bad bytes remain in the data block.
摘要翻译：一种纠正数据块错误的迭代方法。首先使用从数据块的8 B / 10 B解码得到的信息来识别坏字节。在每个识别的坏字节中，随后使用从数据块行的奇偶校验解码得到的信息来识别可疑位。然后，使用从可疑位所在数据块的列的奇偶校验解码得到的信息将每个疑犯位分类为确认的错误位或未确认的错误位。然后校正确认的错误位，与确认的错误位复位相对应的奇偶校验位和坏字节清零。如果数据块中存在一个或多个不良字节，则重复该过程。

摘要： A congestion/non-congestion determining unit determines whether or not a communications network is in a congestion state. An FEC (forward error correction) packet generator generates error correction packets containing error correction data for correcting error of streaming data contained in transmission packets. When the determination result changes from a non-congestion state to a congestion state, an FEC transmission controller controls the error-correction-packet generation so as to change the number of error correction packets. The present invention is applicable to a remote TV conference system.

摘要： A demodulator 101 demodulates modulated data into demodulated data, detects a demodulation error, and sets an erasure flag. An error corrector 104 performs erasure correction for the demodulated data retained in a demodulated data memory 102 by using the erasure flag retained in an erasure flag memory 103. An erasure flag eraser 105 instructs the erasure flag memory 103 to erase an erasure flag which is set to the corrected demodulated data. In this way, the erasure correction which has a higher correction capability and is effective particularly for burst errors is realized.

摘要： A multi-level error correction technique for maintaining data integrity in a data recording/recovery device is presented. Data is stored in buffer packets in a segment of a data buffer before being recorded to a storage medium. Error correction codes are generated over a plurality of instances of a plurality of buffer packet patterns in the segment, and are recorded along with all of the buffer packets onto a storage medium. During data recovery from the storage medium, recovered error correction code packets are used to perform multi-level segment correction on the recovered data packets.

摘要： The invention relates to a transmitting system, comprising an SNS client that receives SNS messages from at least one SNS server, and a transmitter which transmits a broadcast signal, including the SNS messages and mobile service data, for a mobile broadcast. The transmitter includes: an RS frame encoder, which performs RS encoding and CRC encoding on the mobile service data for the mobile broadcast so as to build RS frames, and divides each RS frame into a plurality of portions; a group-forming unit, which forms data groups that contain each of the plurality of portions, and which adds known data sequences and signaling data to each data group; an inter-leaver for interleaving data of the data groups; and a trellis encoding unit for trellis-encoding the interleaved data.
