    Abstract: Provided is a method and apparatus for performing intra-prediction using an adaptive filter. The method for performing intra-prediction comprises the steps of: determining whether or not to apply a first filter for a reference pixel value on the basis of information of a neighboring block of a current block; applying the first filter for the reference pixel value when it is determined to apply the first filter; performing intra-prediction on the current block on the basis of the reference pixel value; determining whether or not to apply a second filter for a prediction value according to each prediction mode of the current block, which is predicted by the intra-prediction performance on the basis of the information of the neighboring block; and applying the second filter for the prediction value according to each prediction mode of the current block when it is determined to apply the second filter.

    Abstract: An apparatus for decoding a video signal, comprising: an entropy decoding unit configured to decode information indicating whether 5 a prediction mode of a current block corresponds to an intra prediction or an inter prediction; a prediction mode determination unit configured to determine an intra prediction mode of the current block when the prediction mode of the current block corresponds to the intra prediction; 10 a scanning unit configured to perform a scan for the current block; and an inverse-transform unit configured to perform an inverse-transform for residual signal of the current block using at least one of discrete cosine transform (DCT) or discrete sine transform (DST), wherein the scanning unit is further configured to determine, based on the intra 15 prediction mode of the luma component, a scanning type of the luma component and a chroma component of the current block, and wherein when a size of the current block is 4x4, the inverse transform for the luma component of the current block is performed using only the DST.
