Abstract
Methods and apparatus for video coding are disclosed. According to this method, a bitstream corresponding to encoded data of the video sequence is generated at an encoder side or received at a decoder side, where the bitstream comprises a first syntax related to AMVR precision, and wherein the syntax related to the AMVR precision is coded by context coding bins with at least two contexts. One or motion vectors for the target block are encoded, at the encoder side, or decoded, at the decoder side, utilizing information comprising the AMVR precision.
