摘要： The present invention provides a method and apparatus for compressing or decompressing data in Fiber Channel (FC) services. In the solution of the present invention, when compressing FC data, a K code indicator bit and an ERR code indicator bit are compressed into a K/ERR code indicator bit, and 8b codes and the K/ERR code indicator bit are compressed into 9b codes; when decompressing FC data, the 9b code is decompressed into 8b codes and a K/ERR code indicator bit, and the K/ERR code indicator bit is decompressed into a K code indicator bit and an ERR code indicator bit. The solution provided by the present invention overcomes the disadvantages that in conventional art, when processing FC service, the K code indicator bit and the ERR code indicator bit must be retained, and the K code and the ERR code are processed separately, which lead to a high bandwidth utilization ratio and a complex processing procedure. The solution provided by the present invention fully utilizes the current FC service bandwidth, enables to process the FC service with fewer resources, greatly simplifies the FC service processing, and promotes the spread of the FC technology.

摘要： A nucleic acid storage system (20), a method and an apparatus for storing information units in nucleic acid molecules are described. A coding scheme is applied which avoids generation of self-reverse complementary nucleic acid strands. A first code generator (28) provides first code words, wherein the reverse complementary words also belong to the first code. A second code generator (30) provides second code words, wherein the reverse complementary words also belong to the second code. No code word exists within the first and second code which belongs to both codes. An information encoder (32) encodes the information units using first code words. A multiplexer (34) generates multiplexed code word sequences wherein after a predefined amount of first code words one second code word is inserted. A nucleic acid synthesizer (36) synthesizes nucleic acid molecules wherein a sequence of nucleotides is arranged to correspond to the multiplexed code word sequence.

摘要： A system, method and computer program product are provided to encode data for recording onto media whereby modulation and linear constraints from a concatenated code or product code are imposed. A first array of unencoded user data is generated. Each row is modulation encoded to enforce a first modulation constraint; the array is transformed into a second array which is transformed into a third array having predetermined empty locations in each column interleaved with the modulated data. A C2-parity byte is computed for at least some of the empty locations of the third array and a fourth array is generated. C1-parity symbols in each row are computed, generating a fifth array. A second modulation constraint is enforced on each C1-parity symbol in each row of the fifth array, generating a sixth array. The rows of the sixth array are assembled with header and sync fields for recording onto a recording media.

摘要： In a channel encoder comprising a dk-encoder stage (101) and a precoding stage (103), obeyance of a repeated minimum transition runlength constraint (r) is achieved because, between the dk-encoder (101) and the precoder (103), data are passed through an RMTR encoder (102) which replaces occurrences of a forbidden pattern (fp) by a current replacement pattern having the same length as the forbidden pattern (fp). By appropriately selecting current replacement patterns from a predefined set of two different replacement patterns (rp1, rp2), DC-control can be achieved for the encoder output. The corresponding decoder is described, which also employs pattern replacement.

摘要： An encoding scheme generates an encoded nine bit code word from each input eight bit data word. The coding scheme is such that the encoded data words have advantageous properties, such as a minimum of two polarity transitions in each encoded data word, and a maximum of five bits without a polarity transition. Five of the bits from the input eight bit data word appear unchanged in the encoded data word, while the other four bits of the encoded data word are obtained by applying appropriate logical operators to the remaining three bits of the input data word in combination with two of the five bits that appear unchanged in the encoded data word. Exception codes can also be defined, that is, nine bit code words that cannot be obtained from any eight bit data word by means of the coding scheme, and can be used to embed control information into the data stream. For example, the exception codes may advantageously have six or seven bits without a polarity transition.

摘要： Methods and apparatuses for encoding and decoding RLL MTR codes such as a rate 16/17 RLL(6) MTR(4) code and a rate 24/25 RLL(6) MTR(4) code. The encoding method comprises a step of converting a data word into a temporary codeword according to a conversion table for enforcing RLL and MTR constraints, a step of checking violations of the maximum-runlength constraint when concatenating a present and an earlier codeword, and when a violation is detected, a step of selecting one of the present or earlier temporary codeword which has at least four contiguous zeroes adjacent to their boundary, and a step of converting the four zeroes in order to meet the maximum-runlength constraint. Error propagation is reduced by converting one word only upon detection of RLL violation.

摘要： There is provided an optical information detecting method. The method includes: detecting an image of a source data page coded with balanced codewords by the use of 1:N (where N is greater than 1) excessive detection pixels; determining a distribution pattern of valid detection pixels and invalid detection pixels to be corrected in the detected image by the use of a light intensity distribution of the detected image; and dividing the detected image into balanced codeword detecting areas corresponding to the balanced codewords and sampling data of the balanced codeword detecting areas by the use of the determined distribution pattern and an optical distribution characteristic of the balanced codewords. Accordingly, it is possible to efficiently detect optical information by the use of a 1:N over-sampling method. Specifically, the distribution pattern of valid detection pixels and invalid detection pixels in the detected image of a data page can be properly used to sample a balanced code.
