Abstract
The present disclosure provides a coding method, wherein the coding includes decoding or encoding, and the method comprises determining whether a current coding unit is predicted by application of combined inter-intra prediction (CIIP); and in response to determining that the current coding unit is predicted by application of CIIP, setting a boundary strength of a boundary of the current coding unit to a first value.
Claims21
A coding method, comprising:
- determining whether a current coding unit is predicted by an application of combined inter-intra prediction (CIIP);
- in response to determining that the current coding unit is predicted by the application of CIIP, setting a boundary strength of a boundary of the current coding unit to a first value, wherein coding includes decoding or encoding;
- upon determination that the current coding unit is not predicted by the application of CIIP, determining whether the boundary of the current coding unit is an edge of a transform block and the transform block contains one or more non-zero transform coefficient levels;
- and
- upon determination that the boundary of the current coding unit is an edge of a transform block and the transform block contains one or more non-zero transform coefficient levels, setting the boundary strength of the boundary of the current coding unit to a second value.
