Sughrue Mion, PLLC
Adaptive motion vector resolution signaling
A method, computer program, and computer system for video coding is provided. Video data including at least two frames is received. A motion vector difference is calculated between two frames from among the at least two frames. An adaptive motion vector resolution usage flag is checked. The adaptive motion vector resolution flag may correspond to a precision value and an adaptive motion vector resolution usage value corresponding to whether adaptive motion vector resolution is enabled or disabled. The video data is encoded based on the adaptive motion vector resolution usage value, whereby the motion vector difference is encoded based on the precision value.
