Abstract
An electronic apparatus performs a method of encoding and decoding video data. The method comprises: receiving, from a bitstream, the video data corresponding to a coding unit; receiving, from the video data, a first syntax element that defines a Motion Estimation Region (MER); receiving a plurality of second syntax elements from the video data, wherein the plurality of second syntax elements indicate whether the coding unit is in a subblock-based temporal motion vector prediction (SbTMVP) mode; in accordance with a determination that the coding unit is in the SbTMVP mode, determining whether both a spatial neighboring block used to determine a temporal vector of the coding unit and the coding unit are within the same MER; and in accordance with a determination that both the spatial neighboring block and the coding unit are within the same MER, setting the temporal vector of the coding unit to zero.
