    摘要: An apparatus for processing a video signal and method thereof are disclosed. The present invention includes receiving the video signal, extracting discrete cosine transform information from the video signal, and performing inverse discrete cosine transform using the discrete cosine transform information, wherein the discrete cosine transform information indicates a rearrangement mode of blocks in the discrete cosine transform. Accordingly, a video signal processing method of the present invention, improves efficiency of discrete cosine transform in a manner of rearranging blocks of video signal by considering a prediction mode prior to performing discrete cosine transform. The present invention enhances coding efficiency by using a row or column shifted matrix and shift information including information relevant to the row or column shifted matrix and by directly performing RRU (reduced resolution update) scheme on a discrete cosine transform/inverse discrete cosine transform domain.

    摘要: The present invention relates to a method for decoding a video signal, comprising: obtaining adaptive transform size flag information for a 1st coding unit, the adaptive transform size flag information indicating whether a coding unit is partitioned in to coding units each of which has a half size in horizontal and vertical directions; obtaining adaptive transform size flag information for each 2nd coding unit, if the adaptive transform size flag information of a 1st coding unit is true, the 2nd coding unit indicating a sub-block included in the 1st coding unit; determining a size of a transform unit based on the adaptive transform size flag information; wherein the adaptive transform size flag information is obtained based on a size of a current transform unit, a minimum transform size, and a maximum transform size.
