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: Disclosed are a method and apparatus for video encoding/decoding based on a multi-layer. The method for video decoding to support a plurality of layers, includes: decoding Picture Order Count (POC) reset information indicating whether a POC value of a current picture is reset to 0; calculating the POC value of the current picture and respective POC values of a long-term reference picture and a short-term reference picture in a decoded picture buffer (DPB) referred by the current picture; and configuring a Reference Picture Set (RPS) for inter-prediction of the current picture based on the POC value of the long-term reference picture and the POC value of the short-term reference picture.
