Abstract:
A digital data coding method for coding one block of digital data at a time, each block composed of a plurality of digital data values, each digital data value representing a value of a corresponding component, said digital data coding method comprising:a first step for calculating specific weight data for each component; a second step for assigning a number of bits to each component according to said weight data, wherein said number of bits corresponds to a plurality of weight data; a third step for calculating a total of the number of bits of one block, the number of bits being assigned in said second step; a fourth step for comparing between the total value of the number of bits of one block calculated in said third step with a predetermined aim value; and a fifth step for increasing or decreasing said weight data calculated in said first step according to the comparison in said fourth step, wherein, by repeating said first step to said fifth step, the total number of bits of one block is converged into a predetermined range, wherein said weight data is repeatedly increased or decreased with repeating said first step to said fifth step.
