Method and apparatus for encoding/decoding the motion vectors of a plurality of reference pictures, and apparatus and method for image encoding/decoding using same
A video decoding method using an inter prediction, includes: reconstructing a first differential motion vector and a second differential motion vector of a current block by decoding encoded data; deriving a first predicted motion vector and a second predicted motion vector of the current block from one or more neighboring blocks of the current block; generating a first motion vector of the current block by adding the first candidate motion vector to the first differential motion vector, and a second motion vector of the current block by adding the second candidate motion vector to the second differential motion vector; generating a predicted block of the current block by using the first and second motion vectors; reconstructing a residual block by decoding residual signals included in the encoded data; and adding each pixel value of the predicted block to a corresponding pixel value of the residual block.
