Abstract
A method of video decoding includes creating a candidate list for a current block in a current picture included in a coded video bitstream. The method further includes determining a coding mode for a candidate block associated with the current block. The method further includes determining whether to add, to the candidate list, a vector associated the candidate block based on the determined coding mode. The method further includes reconstructing the current block using at least one candidate from the candidate list.
Claims12
A method of video encoding comprising:
- determining that a current block in a current picture is to be encoded in an intra-inter blending mode;
- determining a coding mode for a candidate block neighboring the current block;
- in response to (i) the determination that the current block is to be encoded in the intra-inter blending mode and (ii) the determined coding mode for the neighboring candidate block being an intra block copy mode, setting the neighboring candidate block as unavailable so that a block vector of the neighboring candidate block is not included in a candidate list;
- and
- encoding the current block based on at least one candidate from the candidate list.
A video decoding apparatus, comprising:
- processing circuitry configured to
- determine that a current block in a current picture is encoded in an intra-inter blending mode;
- determine a coding mode for a candidate block neighboring the current block;
- in response to (i) the determination that the current block is to be encoded in the intra-inter blending mode and (ii) the determined coding mode for the neighboring candidate block being an intra block copy mode, set the neighboring candidate block as unavailable so that a block vector of the neighboring candidate block is not included in a candidate list;
- and
- reconstruct the current block based on at least one candidate from the candidate list.
A method of processing visual media data, the method comprising:
- performing a conversion between a visual media file and a bitstream of visual media data according to a format rule, wherein
- the bitstream includes coding information of a current block, the coding information indicating that the current block is encoded in an intra-inter blending mode;
- the format rule specifies that a coding mode for a candidate block neighboring the current block is determined;
- the format rule specifies that, in response to (i) the determination that the current block is to be encoded in the intra-inter blending mode and (ii) the determined coding mode for the neighboring candidate block being an intra block copy mode, the neighboring candidate block is set as unavailable so that a block vector of the neighboring candidate block is not included in a candidate list;
- and
- the format rule specifies that the current block is encoded based on at least one candidate from the candidate list.
