Abstract: An intra prediction method and a device using the intra prediction method are provided. The intra prediction method includes the steps of: deriving a current prediction mode as a prediction mode of a current block; constructing neighboring samples of the current block with available reference samples; filtering the available reference samples; and generating predicted samples of the current block on the basis of the filtered available reference samples. The filtering step includes performing the filtering using the available reference sample located in the prediction direction of the current prediction mode and a predetermined number of available reference samples neighboring to the prediction direction of the current prediction mode.

Abstract: A method for selecting a motion vector predictor is provided. The method of selecting a motion vector predictor includes the steps of selecting motion vector predictor candidates for a current block and selecting a motion vector predictor of the current block out of the motion vector predictor candidates, wherein the motion vector predictor candidates for the current block include a motion vector of a first candidate block which is first searched for as an available block out of left neighboring blocks of the current block and a motion vector of a second candidate block which is first searched for as an available block out of upper neighboring blocks of the current block.
