Title:
METHODS AND APPARATUS FOR VIDEO CODING USING NON-ADJACENT MOTION VECTOR PREDICTION
Document Type and Number:
WIPO Patent Application WO/2023/246408
Kind Code:
A1
Abstract:
Methods for reducing buffer requirement associated with non-adjacent MVP (Motion Vector Prediction). According to this method, one or more first non-adjacent MVP (Motion Vector Prediction) candidates are derived based on previous motion information in a first region comprising a current CTU (coding tree unit) of the current block, wherein the first region is limited to be within one or more pre-define distances in a vertical direction, a horizontal direction or both from the current CTU. A merge candidate list comprising said one or more first non-adjacent MVP candidates is generated. The merge list is then used to encode or decode motion information.
