Claim 7:
8. An apparatus for intra- or inter-prediction processing of a video frame, including:
at least one processor; and
a memory coupled to the at least one processor and storing executable instructions, which when executed by the at least one processor, instruct the at least one processor to perform operations comprising:
obtaining a reference sample;
obtaining a fractional sample position p; and
filtering, using a subpixel interpolation filter, the reference sample to obtain a predicted sample value, wherein filter coefficients of the subpixel interpolation filter satisfy a linear combination of the fractional sample position p and a filter strength parameter S, wherein the subpixel interpolation filter is a smoothing filter that is a parallel combination of two phase-dependent linear filters and a low-pass filter.
