Abstract
A method and an apparatus for video encoding/decoding based on an intra-block copy are disclosed. A method for decoding video data comprises decoding coding information for a chroma block from a bitstream, determining that the chroma block is decoded using intra-block copy based on the coding information, identifying a previously decoded luma block using the intra-block copy in a luma area corresponding to the chroma block, deriving a block vector for the chroma block based on a block vector of the previously decoded luma block, and deriving a prediction block for the chroma block based on the block vector of the chroma block.
