    • A method and apparatus for encoding and decoding a motion vector of a current block. The method of encoding including: generating information about the motion vector based on a motion vector of a current block and a motion vector predictor of the current block by estimating the motion vector and determining a first motion vector predictor candidate from among a plurality of motion vector predictor candidates as the motion vector predictor based on a result of the estimating; and generating a virtual motion vector by using a second motion vector predictor candidate and the information about the motion vector, generating vector differences between the virtual motion vector and the plurality of motion vector predictor candidates, comparing the vector differences with the information about the motion vector, and selectively excluding the second motion vector predictor candidate according to the comparing.
    • 一种用于对当前块的运动矢量进行编码和解码的方法和装置。 编码方法包括:基于当前块的运动矢量和当前块的运动矢量预测器,通过估计运动矢量并从多个运动矢量中确定第一运动矢量预测器候选来生成关于运动矢量的信息 基于估计结果的预测候选作为运动矢量预测器; 以及通过使用第二运动矢量预测器候选和关于运动矢量的信息来生成虚拟运动矢量,生成虚拟运动矢量和多个运动矢量预测器候选之间的矢量差,将矢量差与关于运动矢量的信息进行比较 ,并且根据该比较选择性地排除第二运动矢量预测器候选。
