Method and apparatus for signaling an offset in video coding for intra block copy and/or inter prediction
Aspects of the disclosure provide a method and an apparatus including processing circuitry for video decoding. The processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream. The prediction information indicates a prediction mode for the current block being an inter prediction mode or an intra block copy (IBC) mode. The processing circuitry selects a base vector from a candidate list including a block vector candidate used in the IBC mode and determines an offset vector based on offset information that includes directions and sizes for constructing offset vectors. The processing circuitry determines a vector of the current block based on the base vector and the offset vector. The vector is a block vector when the prediction mode is the IBC mode and the vector is a motion vector when the prediction mode is the inter prediction mode.
