Abstract

According to one aspect of the present disclosure, a method of decoding is provided. The method may include determining, by a processor, refined temporal motion information of a subblock-based temporal motion vector prediction (SbTMVP) candidate. The method may include determining, by the processor, a subblock merge candidate list for a current block includes the SbTMVP candidate with the refined temporal motion information. The method may include decoding, by the processor, the current block based on the subblock merge candidate list.
