    摘要: A method of processing a video signal is disclosed. The present invention includes obtaining a current macroblock type, obtaining skip or direct mode indication information on a partition of the current macroblock according to the current macroblock type, deriving a motion vector of the partition according to the skip or direct mode indication information, and predicting a pixel value of the partition using the motion vector. Accordingly, the present invention obtains a pixel value of a reference block close to an original video using a motion vector, thereby enhancing a reconstruction ratio of the macroblock. As a macroblock uses skip or direct prediction indication information, it is unnecessary to separately code skip mode indication information and direct mode indication information on the macroblock, whereby an information size to be coded can be reduced.

    摘要: The present invention relates to a video signal decoding method for adding an intra prediction mode as a sub-macroblock type to prediction of a macroblock in coding a video signal. The present invention includes obtaining a macroblock type, obtaining a sub-macroblock type when a macroblock includes a plurality of coded sub-macroblocks according the macroblock type, obtaining flag information indicating a DC (discrete cosine) transform size, determining the DC transform size of the coded sub-macroblock based on the flag information, when the sub-macroblock is intra prediction coded based on the sub-macroblock type, determining a prediction size of the intra prediction coded sub-macroblock based on the determined DC transform size, obtaining prediction direction information from a block adjacent to the sub-macroblock based on the prediction size of the sub-macroblock, and obtaining a prediction value of the sub-macroblock based on the prediction direction information. Accordingly, the present invention is able to raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock type in predicting a macroblock.

    摘要: 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.
