Method and apparatus for processing video data

A method of encoding video data, comprising:

• determining whether to apply a first prediction mode to a current block, the first mode referring to another block in a current picture;
• configuring a block vector candidate list of the current block based on the first prediction mode being applied to the current block;
• generating a prediction sample of the current block based on a block vector included in the block vector candidate list;
• and
• encoding information related to a prediction of the current block,
• wherein configuring the block vector candidate list comprises:
• configuring the block vector candidate list only based on a spatial neighboring block to which the first prediction mode is applied, an history-based motion vector prediction (HMVP) candidate to which the first prediction mode is applied, and a zero vector by adding a block vector of the spatial neighboring block, the HMVP candidate, and the zero vector to the block vector candidate list in an order of the block vector of the spatial neighboring block, the HMVP candidate, and the zero vector.

A transmission method for data comprising a bitstream for an image, the method comprising:

• obtaining the bitstream for the image;
• and
• transmitting the data comprising the bitstream,
• wherein the bitstream is generated by performing steps of:
• determining whether to apply a first prediction mode to a current block, the first mode referring to a block different from the current block in a current picture;
• configuring a block vector candidate list of the current block based on the first prediction mode being applied to the current block;
• generating a prediction sample of the current block based on a block vector included in the block vector candidate list;
• and
• encoding information related to a prediction of the current block,
• wherein configuring the block vector candidate list comprises:
• configuring the block vector candidate list only based on a spatial neighboring block to which the first prediction mode is applied, an history-based motion vector prediction (HMVP) candidate to which the first prediction mode is applied, and a zero vector by adding a block vector of the spatial neighboring block, the HMVP candidate, and the zero vector to the block vector candidate list in an order of the block vector of the spatial neighboring block, the HMVP candidate, and the zero vector.
