Method for encoding and decoding motion information, and apparatus for encoding and decoding motion information

摘要

A method of decoding motion information, the method comprising: determining a basic motion vector of a current block; Determining a primary residual motion vector for the current block based on information obtained from the bitstream among at least one primary residual motion vector candidate classified according to the shift distance and the shift direction; And determining the motion vector of the current block by applying the first residual motion vector to the basic motion vector.
