Abstract
In one embodiment, a method for encoding or decoding video content is provided. The method includes determining a set of interpolation filters for use in interpolating sub-pel pixel values and a mapping between interpolation filters in the set of interpolation filters and different sizes of prediction units (PUs) of video content. A PU of video content is received and a size of the received PU is determined The method determines an interpolation filter in the set of interpolation filters based on a mapping between the interpolation filter and the size of the received PU to interpolate a sub-pel pixel value for use in a temporal prediction process for the PU.
