    摘要： 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.

    摘要： Provided is a method of and apparatus for video encoding and decoding based on motion estimation. The method includes generating a motion vector by searching a reference picture using pixels of a current block, generating a prediction motion vector that is a prediction value of the motion vector by searching the reference picture using previously encoded pixels located adjacent to the current block, and encoding the current block based on the motion vector and the prediction motion vector. By accurately predicting the motion vector of the current block, the number of bits required for encoding the motion vector can be reduced, thereby improving the compression rate of video data.
