    • Provided are methods and apparatuses for encoding and decoding a motion vector. The method of encoding the motion vector includes: selecting, as a mode of encoding information about a motion vector predictor of the current block, a first mode in which information indicating the motion vector predictor from among at least one motion vector predictor is encoded or a second mode in which information indicating generation of the motion vector predictor based on blocks or pixels included in a previously encoded area adjacent to the current block is encoded; determining the motion vector predictor of the current block according to the selected mode and encoding the information about the motion vector predictor of the current block; and encoding a difference vector between the motion vector of the current block and the motion vector predictor of the current block.
    • 提供了用于对运动矢量进行编码和解码的方法和装置。 对运动矢量进行编码的方法包括:作为对当前块的运动矢量预测器的信息进行编码的模式,选择对从至少一个运动矢量预测器中的运动矢量预测器进行编码的信息进行编码的第一模式, 第二模式,其中编码基于与当前块相邻的先前编码区域中包括的块或像素的运动矢量预测器的生成的信息; 根据所选择的模式确定当前块的运动矢量预测器,并对关于当前块的运动矢量预测器的信息进行编码; 并且对当前块的运动矢量与当前块的运动矢量预测器之间的差矢量进行编码。
