    Abstract: In one embodiment, a method of predicting a motion vector for a current block in a current picture by a moving picture decoding device includes obtaining, by the moving picture decoding device, a direction of a reference picture of the current picture, based on comparison of a display order of the reference picture and a display order of the current picture, obtaining, by the moving picture decoding device, at least three motion vectors for at least three other blocks than the current block based on the direction of the reference picture, predicting, by the moving picture decoding device, a motion vector for the current block by using a median operation of the at least three motion vectors and decoding the current block in the current picture using the predicted motion vector for the current block.

    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.
