20120072226PARCOR COEFFICIENT QUANTIZATION METHOD, PARCOR COEFFICIENT QUANTIZATION APPARATUS, PROGRAM AND RECORDING MEDIUM
On a criterion to minimize the entropy of the linear prediction residual of the input signal used for calculation of the input PARCOR coefficient sequence, PARCOR coefficients with larger absolute values are quantized with higher quantization precisions so as to reduce ...

20110305272ENCODING METHOD, DECODING METHOD, ENCODING DEVICE, DECODING DEVICE, PROGRAM, AND RECORDING MEDIUM
To improve the encoding compressibility of prediction residuals. An encoder performs prediction analysis of input time-series signals to generate prediction residuals expressed by integers, and sets an integer separation parameter that depends on the amplitude of the pr...

20110274165PARAMETER SELECTION METHOD, PARAMETER SELECTION APPARATUS, PROGRAM, AND RECORDING MEDIUM
Provided that a first segment is an earliest time segment included in a discrete time segment, and a second segment is a time segment subsequent to the first segment, a positive second-segment parameter that corresponds to a weakly monotonically increasing function valu...

20110254713ENCODING METHOD AND DECODING METHOD, AND DEVICES, PROGRAM AND RECORDING MEDIUM FOR THE SAME
Information that includes first information identifying integer quotients obtained by divisions using prediction residuals or integers not smaller than 0 that increase monotonically with increases in the amplitude of the prediction residuals, as dividends, and a separat...

20110158328ENCODING METHOD, ENCODING DEVICE, DECODING METHOD, DECODING DEVICE, PROGRAM, AND RECORDING MEDIUM
A frame formed of a plurality of code words encoded with an encoding mode in which two different types of code words are assigned one-to-one to two smallest quantization intervals is checked to determine whether it contains just the two types of code words assigned to t...

20100017373ENCODER, DECODER, THEIR METHODS, PROGRAMS THEREOF, AND RECORDING MEDIA HAVING PROGRAMS RECORDED THEREON
In encoding for putting one or more files and/or one or more files in a folder into a single archive file, original hierarchy information and standard hierarchy information generated by converting characters in a special character coding in each file name to characters ...
