Abstract: The present invention provides a method for encoding a video signal, comprising: generating prediction pixels for the first row or column of a current block on the basis of boundary pixels neighboring to the current block; predicting remaining pixels within the current block respectively in the vertical direction or horizontal direction using the prediction pixels for the first row or column of the current block; generating a difference signal on the basis of the prediction pixels for the current block; and generating a transform-coded residual signal by applying a horizontal transform matrix and a vertical transform matrix to the difference signal.

Abstract: The present invention relates to a method and a device for decoding a bitstream for a video signal, the method comprising the steps of: determining whether at least one neighboring block adjacent to a current block is divided into a plurality of coding blocks within a picture including the current block; if the at least one neighboring block is not divided, obtaining, from the bitstream, flag information indicating whether parameter information for the current block is induced from one of the at least one neighboring block, and inducing the parameter information for the current block from a specific neighboring block among the at least one neighboring block, on the basis of the flag information; obtaining the parameter information for the current block from the bitstream if all of the at least one neighboring block is divided; and decoding the current block on the basis of the parameter information for the current block.
