Abstract
A method of video processing is described. The method includes determining, for a conversion between a current video block of a video and a coded representation of the video, whether a certain partitioning scheme is allowed for the current video block according to a rule that depends on a coding mode type used for representing the current video block in the coded representation and a dimension of the current video block; and performing the conversion based on the determining.
Claims20
A method of processing video data, comprising:
- determining, for a conversion between a current video block of a video and a bitstream of the video, whether a partitioning scheme is allowed for the current video block according to a rule that depends on a mode type of the current video block and a dimension of the current video block;
- and
- performing the conversion based on the determining;
- wherein the partitioning scheme comprises:
- a QT (quaternary tree) split in which the current video block is split into four parts in both horizontal and vertical directions,
- a vertical TT (ternary tree) split in which the current video block is split into three parts in a vertical direction,
- a horizontal TT split in which the current video block is split into three parts in a horizontal direction,
- a vertical BT (binary tree) split in which the current video block is split into two parts in a vertical direction, or
- a horizontal BT split in which the current video block is split into two parts in a horizontal direction.
An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- determine, for a conversion between a current video block of a video and a bitstream of the video, whether a partitioning scheme is allowed for the current video block according to a rule that depends on a mode type of the current video block and a dimension of the current video block;
- and
- perform the conversion based on the determining;
- wherein the partitioning scheme comprises:
- a QT (quaternary tree) split in which the current video block is split into four parts in both horizontal and vertical directions,
- a vertical TT (ternary tree) split in which the current video block is split into three parts in a vertical direction,
- a horizontal TT split in which the current video block is split into three parts in a horizontal direction,
- a vertical BT (binary tree) split in which the current video block is split into two parts in a vertical direction, or
- a horizontal BT split in which the current video block is split into two parts in a horizontal direction.
A non-transitory computer-readable storage medium storing instructions that cause a processor to:
- determine, for a conversion between a current video block of a video and a bitstream of the video, whether a partitioning scheme is allowed for the current video block according to a rule that depends on a mode type of the current video block and a dimension of the current video block;
- and
- perform the conversion based on the determining;
- wherein the partitioning scheme comprises:
- a QT (quaternary tree) split in which the current video block is split into four parts in both horizontal and vertical directions,
- a vertical TT (ternary tree) split in which the current video block is split into three parts in a vertical direction,
- a horizontal TT split in which the current video block is split into three parts in a horizontal direction,
- a vertical BT (binary tree) split in which the current video block is split into two parts in a vertical direction, or
- a horizontal BT split in which the current video block is split into two parts in a horizontal direction.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
- determining, for a current video block of a video, whether a partitioning scheme is allowed for the current video block according to a rule that depends on a mode type of the current video block and a dimension of the current video block;
- and
- generating the bitstream based on the determining;
- wherein the partitioning scheme comprises:
- a QT (quaternary tree) split in which the current video block is split into four parts in both horizontal and vertical directions,
- a vertical TT (ternary tree) split in which the current video block is split into three parts in a vertical direction,
- a horizontal TT split in which the current video block is split into three parts in a horizontal direction,
- a vertical BT (binary tree) split in which the current video block is split into two parts in a vertical direction, or
- a horizontal BT split in which the current video block is split into two parts in a horizontal direction.
