Abstract:
1. A method for constructing, from a plurality of digital media signal input samples, at least one interpolated digital media input sample, by determining interpolation coefficients of a symmetric interpolation kernel, C, the method comprising the steps of: (a) determining a value x, proportional to a distance between the sample to be interpolated and one of the media signal input samples; (b) determining a first interpolation coefficient from the kernel and storing the first interpolation coefficient in a memory; (c) determining an intermediate value proportional to the sum of C(x+L) and C(x−L−1) where the parameter L is a non-negative integer in a kernel support interval; (d) determining a subsequent interpolation coefficient dependent upon the first interpolation coefficient and the intermediate value, to thereby construct, from the plurality of digital media signal input samples, the at least one interpolated digital media input sample; and (e) outputting or storing the at least one interpolated digital media input sample for further processing, wherein all of said steps are implemented using a computer.
