An intra prediction method and a device using the intra prediction method are provided. The intra prediction method using a DC mode includes setting a bottom-right pixel to a DC-predicted value, interpolating the bottom-right pixel and an n-th top reference pixel to derive predicted values of an n-th column and interpolating the bottom-right pixel and an n-th left reference pixel to derive predicted values of an n-row, and performing bidirectional linear interpolation to derive predicted values of pixels included in a prediction unit other than the n-th row and the n-th column.

Disclosed are a method for setting a motion vector list and an apparatus using the same. The method for setting the motion vector list and the apparatus using the same may include the steps of: determining the presence of a first motion vector or a second motion vector by a sequential determination process in a first spatial candidate prediction group; and setting the first motion vector or the second motion vector produced through the sequential determination process as the candidate prediction motion vector. Thus, the encoding/decoding time and the complexity can be reduced by restricting the scaling number in a process for scanning the candidate prediction motion vector.

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.

Disclosed are a method and device for encoding or decoding video signals. The video signal processing method according to the present invention can enhance processing efficiency by using a structure whereby a single unit is recursively divided into a plurality of units. A method is provided in which bits can be used efficiency by hierarchically employing coding block pattern information under a unit structure able to be divided in this way. Further, residual data is rearranged so as to allow efficient coding by employing spatial distribution of the residual data.
