    Abstract: The present invention relates to a method for decoding a video signal, comprising the steps of: acquiring a transform size flag of the current macroblock from a video signal; checking the number of non-zero transform coefficients at each pixel position in a first transform block which corresponds to the transform size flag; changing a scan order of the first transform block by prioritizing the position of the pixel having the greatest number of the non-zero transform coefficients in the first transform block; determining the number of the non-zero transform coefficients at each pixel position in a second transform block, and setting the changed scan order of the first transform block as an initialized scan order of the second transform block; adding the number of the non-zero transform coefficients at each pixel position in the first transform block and the number of the non-zero transform coefficients at each pixel position in the second transform block, and changing the scan order of the second transform block by prioritizing the position of the pixel having the greatest number of the non-zero transform coefficients; and decoding the transform coefficients arranged in the scan order changed in the previous step, wherein the first transform block and the second transform block have sizes corresponding to the transform size flag, and are contained in the current macroblock.

    Abstract: 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.

    Abstract: A method and an apparatus of decoding a video signal are provided. The present invention includes the steps of parsing first coding information indicating whether a residual data of an image block in the enhanced layer is predicted from a corresponding block in the base layer, from the bitstream of the enhanced layer, and decoding the video signal based on the first coding information. And, the step of parsing includes the step of performing modeling of the first coding information based on second coding information indicating whether prediction information of the corresponding block in the base layer is used to decode the image block in the enhanced layer. Accordingly, the present invention raises efficiency of video signal processing by enabling a decoder to derive information on a prediction mode of a current block in a decoder instead of transferring the information to the decoder.
