Title:
METHOD AND APPARATUS OF SUBBLOCK-BASED TEMPORAL MOTION VECTOR PREDICTION WITH REORDERING AND REFINEMENT IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2024/027784
Kind Code:
A1
Abstract:
A method and apparatus for video coding using SbTMVP. According to the method, a target motion shift is determined from one or more neighbouring blocks comprising at least one non-adjacent spatial neighbouring block of the current block. A collocated block in a reference picture is determined based on the target motion shift. Subblock motion information is derived for subblocks of the current block based on motion information of corresponding subblocks of the collocated block. An SbTMVP candidate is generated for the current block based on the subblock motion information for the subblocks of the current block. The current block is encoded or decoded by using a motion prediction set comprising the SbTMVP candidate
