摘要： When recording data on a record carrier control of the DC content of the data as recorded is important in order to allow accurate reproduction of the data. The Digital Sum Value represents the DC content, The Digital Sum Value can be controlled by replacing code words at the output of an encoder by code words that can never occur during encoding. The replacement code word has different parity than the code word it replaces. The resulting stream of code words is subsequently encoded using an NRZI coder, so that the change in parity resulting from the replacement code word results in a change of polarity of the NRZI output. The replacement code word can thus be used to change the polarity of the NRZI output if required to keep the Digital Sum Value low.

摘要： A final 15-bit output code word is generated in response to every 8-bit input code word by referring to a set of encoding tables (120). The encoding tables (120) contain output code words assigned to input code words, and contain state information accompanying each output code word. The state information designates an encoding table among the encoding tables which is used next to generate an output code word immediately following the output code word accompanied with the state information. When given conditions are satisfied, first and second candidate current output code words generated in response to a current input code word by referring to first and second specified ones of the encoding tables (120). One is selected from the first and second candidate current output code words as a final current output code word in response to DSV calculation results. Auxiliary information is superimposed on a sequence of final output code words.

摘要： According to the present invention, an image coding apparatus provides a run-length encoding unit (RLE1) that subjects quantized coefficients which are obtained by quantizing frequency components of an image signal to a variable length coding process by using a run value (Run) that indicates the number of successive zero coefficients and a level value (Lev) that indicates a value of a non-zero coefficient following the zero coefficients. The run-length encoding unit (RLE1) includes a reordering unit (Lreodr) for reordering level values (Lev); a variable length coder (LVLC) for coding reordered level values (ROLev) by using a code table that is selected according to the value of a quantization parameter (QP); a reordering unit (Rreodr) for reordering run values (Run) from high frequency component of the quantized coefficients to low frequency component; and a variable length coder (RVLC) for coding reordered run values (RORun) by using a code table that is selected according to the number of already-processed run values. Accordingly, a variable length coding process for quantized coefficients is carried out at a higher coding efficiency, with redundant information included in the coefficients being effectively reduced.

摘要： Methods are provided for overwriting data in a probe-based data storage device (1) wherein data is represented by the presence and absence of pits formed in a storage surface (4) by a probe of the device. Input data is first coded such that successive bits of a first value in the coded input data are separated by at least one bit of the other value. Overwrite data bits ν 0 ,ν 1 ,ν 2 ,..., are generated from the coded input data bits b 0 , b 1 , b 2 , ..., and the overwrite data bits ν 0 , ν 1 , ν 2 ,..., are then used to overwrite data on the storage surface (4). According to a first method, the overwrite data bits are generated such that, if a pit represents a bit of said first value in the data storage device (1) then ν i = b i -1 for i ≥ 1 and ν 0 has said first value, and if a pit represents a bit of said other value in the data storage device (1) then ν i = b i- 1 for i ≥ 1 and ν 0 has said other value. According to a second method, the overwrite data bits are generated such that, if a pit represents a bit of said first value in the data storage device (1) then ν i = b i- 1 ( b i -2 + b i ) for i ≥ 2, ν 0 has said first value and ν 1 = b 0 , and if a pit represents a bit of said other value in the data storage device (1) then ν i =( b i -1 ( b i -2 + b i )) for i ≥ 2, ν 0 has said other value and ν 1 = b 0 . With both methods, the result of the overwrite operation is to record either the coded input data b 0 , b 1 , b 2 ,..., or its complement b 0 , b 1 , b 2 ,..., depending on whether a pit represents a bit having the first value or a bit having the other value. This result is independent of the bit values of the data which is overwritten.≥
