Patent attributes
A method of decoding video data, including receiving an encoded block of video data that was encoded using an inter-prediction mode, receiving one or more syntax elements indicating a motion vector difference (MVD) associated with the encoded block of video data, determining a current MVD precision, from three or more MVD precisions, for the one or more syntax elements indicating the MVD, wherein the three or more MVD precisions include an N-sample MVD precision, where N is an integer indicating a number of samples indicated by each successive codeword of the one or more syntax elements indicating the MVD, and wherein N is greater than 1, decoding the one or more syntax elements indicating the MVD using the determined current MVD precision, and decoding the encoded block of video data using the decoded MVD.
