Abstract
Aspects of the disclosure provide method and apparatus for video coding. In the method, prediction information of a current block in a current coding tree unit (CTU) from a coded video bitstream is decoded. The prediction information indicates an intra block copy (IBC) mode. Padded values of a reference block are determined based on a block vector that points to the reference block. The padded values of the reference block are copied from a reference sample line. At least a sample of the current block is reconstructed based on the padded values of the reference block.
Claims20
A method for video decoding in a decoder, comprising:
- decoding prediction information of a current block in a current coding tree unit (CTU) from a coded video bitstream, the prediction information indicating an intra block copy (IBC) mode;
- determining padded values of a reference block based on a block vector that points to the reference block, the padded values of the reference block being copied from a reference sample line;
- and
- reconstructing at least a sample of the current block based on the padded values of the reference block.
An apparatus, comprising:
- processing circuitry configured to
- decode prediction information of a current block in a current coding tree unit (CTU) from a coded video bitstream, the prediction information indicating an intra block copy (IBC) mode;
- determine padded values of a reference block based on a block vector that points to the reference block, the padded values of the reference block being copied from a reference sample line;
- and
- reconstruct at least a sample of the current block based on the padded values of the reference block.
A non-transitory computer-readable medium storing instructions which when executed by a computer for video decoding cause the computer to perform:
- decoding prediction information of a current block in a current coding tree unit (CTU) from a coded video bitstream, the prediction information indicating an intra block copy (IBC) mode;
- determining padded values of a reference block based on a block vector that points to the reference block, the padded values of the reference block being copied from a reference sample line;
- and
- reconstructing at least a sample of the current block based on the padded values of the reference block.
