    摘要: The present invention relates to an intra-prediction method and to an encoder and decoder using same. The intra-prediction method according to one embodiment of the present invention comprises the steps of: deriving a prediction mode of a current block; and generating a prediction block with respect to the current block on the basis of the prediction mode of the current block. When the prediction mode of the current block is an intra-angular prediction mode, values of boundary samples from among left boundary samples and upper boundary samples of the prediction block, which are not positioned in a prediction direction of the intra-angular prediction mode, are derived on the basis of reference samples positioned in the prediction direction of the intra-angular prediction mode, and on the basis of adjacent reference samples.

    摘要: Provided are a method for managing a reference picture list, and an apparatus using same. An image decoding method comprises the steps of decoding one picture of second-highest temporal layer pictures in a hierarchical picture configuration; and decoding top temporal layer pictures which precede and follow the second-highest temporal layer pictures with respect to a picture order count (POC) in a POC sequence, respectively. Therefore, available reference pictures remain in a decoded picture buffer (DPB), thereby improving image-encoding efficiency.
