    Abstract: PURPOSE: A method for encoding and decoding a motion vector by using a motion vector predictor and a device thereof are provided to increase encoding efficiency by efficiently encoding and decoding the motion vector. CONSTITUTION: When an MV(Motion Vector) encoding/decoding device performs MV prediction, the device performs a step(0) for inducing a left MV predictor, a step(1) for inducing an upper-end MV predictor, and a step(2) for inducing a temporal MV predictor. When the three MV predictors are induced, the device checks redundancy of an MV to remove a MV predictor having the same MV from an MV predictor list.
