Methods for decoding video, encoding video, and recorded materials readable by computers for the long term

Abstract

The invention relates to a method for decoding video comprising the following steps: acquiring, from bit stream, prediction mode information representing the prediction mode of the current block; determining the set of interpolation filters to be used when predicting the current block, based on at least one of the dimensions of the current block and the prediction mode represented by the prediction mode information; determining the reference position that the current block sample references according to the prediction mode; Determine, within the set of interpolation filters, the interpolation filter that corresponds to the reference position; determine the predicted value of the current sample, based on the reference samples of the current block and this interpolation filter; and restore the current block, based on the predicted value of the current sample.
