INTERPOLATION FILTER SELECTION USING PREDICTION INDEX

摘要

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 prediction indexes of the video content. A unit of video content is received and a prediction index is determined in a plurality of prediction indexes that are used to determine a prediction block for the unit of video content. The method then determines an interpolation filter in the set of interpolation filters based on a mapping between the interpolation filter and the prediction index to interpolate a sub-pel pixel value for use in a temporal prediction process for the unit of video content
