US 2020/0404267 A1 · MOTION AND APPARATUS FOR MOTION FIELD STORAGE IN VIDEO CODING

Abstract

The present disclosure provides method and apparatus for motion field storage in video coding. An exemplary method includes: determining whether a first uni-prediction motion vector for a first partition of a block and a second uni-prediction motion vector for a second partition of the block are from a same reference picture list; and in response to the first uni-prediction motion vector and the second uni-prediction motion vector being determined to be from the same reference picture list, storing, in a motion field of the block, one of the first uni-prediction motion vector and the second uni-prediction motion vector for a subblock located in a bi-predicted area of the block.

Dependent claims

A computer-implemented method, comprising:

determining whether a first uni-prediction motion vector for a first partition of a block and a second uni-prediction motion vector for a second partition of the block are from a same reference picture list;
and
in response to the first uni-prediction motion vector and the second uni-prediction motion vector being determined to be from the same reference picture list, storing, in a motion field of the block, one of the first uni-prediction motion vector and the second uni-prediction motion vector for a subblock located in a bi-predicted area of the block.

An apparatus, comprising:

a memory configured to store instructions;
and
a processor coupled to the memory and configured to execute the instructions to cause the apparatus to:
determine whether a first uni-prediction motion vector for a first partition of a block and a second uni-prediction motion vector for a second partition of the block are from a same reference picture list;
and
in response to the first uni-prediction motion vector and the second uni-prediction motion vector being determined to be from the same reference picture list, store, in a motion field of the block, one of the first uni-prediction motion vector and the second uni-prediction motion vector for a subblock located in a bi-predicted area of the block.

3 more elements

A non-transitory computer-readable storage medium storing a set of instructions that are executable by one or more processors of a device, wherein the execution of the set of the instructions causes the device to perform:

determining whether a first uni-prediction motion vector for a first partition of a block and a second uni-prediction motion vector for a second partition of the block are from a same reference picture list;
and
in response to the first uni-prediction motion vector and the second uni-prediction motion vector being determined to be from the same reference picture list, storing, in a motion field of the block, one of the first uni-prediction motion vector and the second uni-prediction motion vector for a subblock located in a bi-predicted area of the block.
