Title:
適応的動きベクトル解像度を用いるビデオ信号処理方法及び装置
Document Type and Number:
Japanese Patent JP7159354
Kind Code:
B2
Abstract:
A video signal processing method and apparatus for encoding or decoding a video signal are disclosed. More specifically, disclosed are a method for processing a video signal and a video signal processing apparatus for performing same, the method comprising the steps of: forming a motion vector prediction (MVP) candidate list for motion compensation of a current block by using either a first method or a second method; acquiring an MVP of the current block on the basis of the formed MVP candidate list; acquiring a motion vector differential value indicating a difference between a motion vector and the MVP of the current block; correcting the motion vector differential value on the basis of the resolution of the motion vector differential value of the current block, wherein the resolution of the motion vector differential value is any one of a plurality of available resolutions included in a resolution set, and the configuration of the plurality of available resolutions included in the resolution set varies according to which of the first method and the second method is used to form the MVP candidate list of the current block; acquiring a motion vector of the current block on the basis of the MVP and the corrected motion vector differential value; and reconstructing the current block on the basis of the acquired motion vector.
