Abstract

This disclosure relates to signaling, parsing, and using adaptive resolution for motion vector difference in video coding. An example method includes receiving a video bitstream and extracting an inter-prediction syntax element from the video bitstream. The inter-prediction syntax element indicates which single-reference inter-prediction mode is enabled for one or more video blocks of the video bitstream. The method further includes determining whether an adaptive motion vector difference (MVD) mode is enabled for the one or more video blocks. The adaptive MVD mode is a single-reference inter-prediction mode with an adaptive MVD pixel resolution. When the adaptive MVD mode is enabled for the one or more video blocks, the method includes selecting a current MVD pixel resolution from a set of available MVD pixel resolutions. The method also includes decoding the one or more video blocks based on the current MVD pixel resolution.
