VIDEO DECODING METHOD, VIDEO DECODER, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2019/154424

A1

The present application provides a video decoding method and a video decoder. The method comprises: analyzing motion vector difference (MVD) information of a current image block from a code stream; obtaining a motion vector prediction (MVP) value of the current image block; if the MVP is comprised in a target motion vector set corresponding to a target motion vector resolution (MVR), obtaining a motion vector of the current image block on the basis of the MVP, the MVD information, and the MVR, wherein the target motion vector set is one of multiple motion vector sets, the multiple motion vector sets comprise a first motion vector set and a second motion vector set, and a first MVR corresponding to the first motion vector set is different from a second MVR corresponding to the second motion vector set; on the basis of the motion vector having the MVR of the current image block, obtaining a prediction block of the current image block; and reconstructing the current image block on the basis of the prediction block. Embodiments of the present application are favorable for improving the MVP resolution.
