METHOD AND SYSTEM TO ENCODE A SET OF INPUT VALUES INTO A SET OF COEFFICIENTS USING A GIVEN ALGORITHM

摘要

That it supports the scalability of the algorithm of [challenges] prescribed. Using a predetermined algorithm, to select the coefficient to be calculated from the coefficient set can be computed in the input value set by a predetermined algorithm which can calculate the coefficients (201), was selected The invention relates to ( By obtaining 201) set of coefficients, there is provided a method of coding the coefficient set of the set of input values. In the selection, a higher priority is given to the coefficients required computational cost is small compared to other factors. In doing so based on the amount of calculation for the predetermined coefficients, the calculation steps in part, necessary for the calculation of the coefficients of a given computational cost, at least, was subtracted calculations that can be shared with the calculation of the coefficients of the other selected , and, in the calculation step, the calculation result of the shared steps, to be reused (201) calculation of the coefficients of the other sharing the shared computation step is desirable.
