ENCODING METHOD AND APPARATUS THEREFOR, AND DECODING METHOD AND APPARATUS THEREFOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18328572 titled 'ENCODING METHOD AND APPARATUS THEREFOR, AND DECODING METHOD AND APPARATUS THEREFOR

Simplified Explanation

The patent application describes a method for decoding video by predicting the values of current blocks based on reference samples and interpolation filters.

  • Obtains information about the intra prediction mode of a current block from a bitstream.
  • Determines the interpolation filter set to be used for predicting the current block based on the size of the block and the intra prediction mode.
  • Determines the reference location to which a current sample of the block refers based on the intra prediction mode.
  • Selects the interpolation filter from the filter set that corresponds to the reference location.
  • Calculates the prediction value of the current sample using the reference samples and the selected interpolation filter.
  • Reconstructs the current block based on the prediction value of the current sample.


Original Abstract Submitted

Provided is a video decoding method including: obtaining, from a bitstream, intra prediction mode information indicating an intra prediction mode of a current block; determining an interpolation filter set to be used in prediction of the current block, based on at least one of a size of the current block and the intra prediction mode indicated by the intra prediction mode information; determining a reference location to which a current sample of the current block refers according to the intra prediction mode; determining, in the interpolation filter set, an interpolation filter that corresponds to the reference location; determining a prediction value of the current sample, according to reference samples of the current block and the interpolation filter; and reconstructing the current block, based on the prediction value of the current sample.
