Abstract:
A video decoding apparatus includes: a splitter configured to split an image into at least one block; a predictor configured to predict a current sample by using at least one of a value obtained by applying a first weight to a first sample predicted earlier than the current sample in a current block and being adjacent to the current sample in a horizontal direction and a value obtained by applying a first weight to a second sample predicted earlier than the current sample in the current block and being adjacent to the current sample in a vertical direction; and a decoder configured to decode the image by using a residual value of the current sample obtained from a bitstream and a prediction value of the current sample.
