Abstract: In one embodiment, the apparatus includes a decoder. The decoder is configured to obtain first and second motion vectors of a block other than the current block. The other block neighbors the current block at one of a left, top and top right position. The decoder is configured to determine first and second motion vectors of the current block using the first and second motion vectors of the other block such that the first motion vector of the current block has a same direction as the first motion vector of the other block and the second motion vector of the current block has a same direction as the second motion vector of the other block.

Abstract: 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. Some implementations may include obtaining a macroblock type, when a macroblock includes the intra prediction coded sub-macroblock and the inter prediction coded sub-macroblock based on the macroblock type, obtaining prediction mode flag information indicating whether the sub-macroblock is the intra prediction coded or the inter prediction coded, and obtaining a prediction value of the sub-macroblock. Accordingly, implementations disclosed herein may raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock type in predicting a macroblock.
