==SUBBLOCK BASED MOTION VECTOR PREDICTOR DISPLACEMENT VECTOR REORDERING USING TEMPLATE MATCHING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17985127 titled 'SUBBLOCK BASED MOTION VECTOR PREDICTOR DISPLACEMENT VECTOR REORDERING USING TEMPLATE MATCHING

==Simplified Explanation==

The patent application describes a method and apparatus for video encoding/decoding.
* The apparatus includes processing circuitry for receiving prediction information of a current coding block in a current picture from a coded video bitstream.
* The prediction information indicates that the current coding block is coded using a subblock-based temporal motion vector prediction (SbTMVP) mode.
* The apparatus derives multiple displacement vector (DV) candidates by applying multiple DV offset candidates to a fixed DV predictor of the current coding block.
* It compares a template of the current coding block with each of multiple templates located at positions specified by the DV candidates.
* The apparatus calculates a cost value associated with each DV offset candidate based on the comparison.
* It reorders the DV offset indices of the multiple candidates based on their calculated cost values.


==Original Abstract Submitted==

Aspects of the disclosure provide a method and an apparatus for video encoding/decoding. The apparatus includes processing circuitry for: receiving prediction information of a current coding block in a current picture from a coded video bitstream, the prediction information indicating that the current coding block is coded using a subblock-based temporal motion vector prediction (SbTMVP) mode; deriving multiple displacement vector (DV) candidates by applying multiple DV offset candidates to a fixed DV predictor of the current coding block; comparing a template of the current coding block with each of multiple templates, each template of the multiple templates being located at a position specified by a corresponding one of the multiple DV candidates; calculating a cost value associated with each one of the multiple DV offset candidates based on the comparing; and reordering DV offset indices of the multiple DV offset candidates based on their calculated cost values.
