Abstract:
This disclosure describes various interpolation techniques performed by an encoder and a decoder during the motion compensation process of video coding. In one example, an encoder interpolates pixel values of reference video data based on a plurality of different pre-defined interpolation filters. In this example, the decoder receives a syntax element that identifies an interpolation filter, and interpolates pixel values of reference video data based on the interpolation filter identified by the syntax element. In another example, a method of interpolating predictive video data includes generating half-pixel values based on integer pixel values, rounding the half-pixel values to generate half-pixel interpolated values, storing the half-pixel values as non-rounded versions of the half-pixel values, and generating quarter-pixel values based on the non-rounded versions of the half-pixel values and the integer pixel values.

Claim (Index 4):
A method of decoding video data, the method comprising:\n receiving a syntax element that identifies one of a set of filters from a plurality of pre-defined sets of interpolation filters, each of the sets of interpolation filters comprising a plurality of filters to be applied to different sub-pixel positions comprising half-pixel, quarter pixel, and \u215b pixel positions; generating, based on a motion vector, inter-prediction data comprising pixel values that can be used to decode a block of the current frame of the video data, wherein generating the prediction data includes interpolating the pixel values based on: i) integer pixel values within reference video data and ii) the sub-pixel position indicated by the motion vector and iii) the set of interpolation filters identified from the set of plurality of the different pre-defined interpolation filters by the syntax element; and decoding the video data based on the inter-prediction data.
