    Abstract: In one embodiment, a method for a moving picture coding system to derive at least one motion vector of a bi-predictive block in a current picture from a motion vector of a first block in a first picture includes selecting, by the moving picture coding system, a list 1 motion vector of the first block in the first picture as a motion vector for deriving list 0 and list 1 motion vectors of the bi-predictive block if the first block only has the list 1 motion vector, the first picture being permitted to be located temporally before the current picture and permitted to be located temporally after the current picture and deriving the list 0 and list 1 motion vectors of the bi-predictive block by applying a bit operation to the selected motion vector, the bit operation including 8 bits right shift.

    Abstract: In one embodiment, an 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. The present invention includes obtaining a macroblock type, checking whether a macroblock includes a intra prediction coded sub-macroblock and a inter prediction coded sub-macroblock when a macroblock includes a plurality of coded sub-macroblocks according the macroblock type, when the macroblock includes the intra prediction coded sub-macroblock and the inter prediction coded sub-macroblock, obtaining prediction mode flag information indicating whether the sub-macroblock is the intra prediction coded or the inter prediction coded, when the sub-macroblock is the intra prediction coded based on the prediction mode flag information, obtaining prediction direction information from a block adjacent to the sub-macroblock and a prediction value of the sub-macroblock based on the prediction direction information, and when the sub-macroblock is inter prediction coded based on the prediction mode flag information, obtaining motion information from the block adjacent to the sub-macroblock and a prediction value of the sub-macroblock based on the motion 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.
