Simplified Explanation

The abstract describes a method for decoding videos. It involves obtaining information about the type of prediction used for a specific block in the video. Based on this information, the method determines the appropriate interpolation filter to use for predicting the block. It also determines the reference location to which the current sample of the block refers. Using the reference samples and the interpolation filter, the method calculates a prediction value for the current sample. Finally, the method reconstructs the block based on this prediction value.


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.
