Coding mode signaling for small blocks
An apparatus for video decoding includes processing circuitry that decodes prediction information for a current block in a current picture that is a part of a coded video sequence. The processing circuitry determines whether the current block is coded in an intra block copy (IBC) mode based on the prediction information. Responsive to the current block not being coded in the IBC mode, the processing circuitry determines whether a size of the current block is above a threshold. The processing circuitry determines that the current block is coded in an intra prediction mode based on a determination that the size of the current block is not above the threshold. The processing circuitry reconstructs the current block based on the intra prediction mode.
