Patent ID: 8831086

Claim:
A method comprising: identifying a set of filter coefficients associated with a filter for interpolation of predictive data in video encoding, wherein the set of filter coefficients comprises a first set of filter coefficients associated with the filter and forming a first portion of the set of filter coefficients and a second set of filter coefficients associated with the filter and forming a second portion of the set of filter coefficients; generating residual values associated with the first set of filter coefficients based on predictive coding of the first set of filter coefficients relative to filter coefficients associated with a fixed interpolation filter; generating additional residual values associated with the second set of filter coefficients relative to one or more mirrored or rotated values of the first set of filter coefficients; applying quantization to the residual values and the additional residual values; and entropy coding and outputting the quantized residual values and the quantized additional residual values as part of an encoded bitstream.
