Abstract
The present disclosure relates to a method and apparatus for processing a video signal and, more specifically, comprises the steps of: parsing, from a bitstream, an adaptive motion vector resolution (AMVR) enabled flag (sps_amvr_enabled_flag) indicating whether or not adaptive motion vector differential resolution is used; parsing, from the bitstream, an affine enabled flag (sps_affine_enabled_flag) indicating whether or not affine motion compensation is usable; on the basis of the affine enabled flag, determining whether or not the affine motion compensation is usable; when the affine motion compensation is usable, determining, on the basis of the AMVR enabled flag, whether or not the adaptive motion vector differential resolution is used; and, when the adaptive motion vector differential resolution is used, parsing, from the bitstream, an affine AMVR enabled flag (sps_affine_amvr_enabled flag) indicating whether or not the adaptive motion vector differential resolution is usable for the affine motion compensation.
