Abstract
PURPOSE:To contrive the attainment of efficient coding by expressing number of data not being the power to K with the K while making the set of data correspondent to a specific numeral and coding the result when the number of data includes a data not expressed in the power to K. CONSTITUTION:When the data number includes a number not expressed in the power to K, a data set (n1,-nB) is made correspondent to numerals n=n1+n2 N1+n3N1N2+...+nlN1N2...N1-1+...+nBN1N2...NB-1 in coding the data set composed of one (n1) among N1-set of data 0-N1-1, one (nB) among NB-set of data 0-NB-1, and expressed in K and coded. In case of the decoding, the operation of n1=nmodN1-nB=(n-n1-n2N1-n3N 1N2-...-nB-1N1N2...NB-2)/N1 N2...NB-1modNB is applied for the decoding, where nmodN is the residue of the N divided by the N. Thus, required code number is reduced and highly efficient coding is applied.
