Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry. The processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream.

The intra prediction is based on at least a first reference sample in the current picture, and the inter prediction is based on at least a second reference sample in a reference picture of the current picture. Further, the processing circuitry determines coding tools associated with the prediction mode that combines the intra prediction and the inter prediction and reconstruct at least a sample of the current block according to the determined coding tools associated with the prediction mode.

The first partition of the current block is reconstructed based on the first prediction mode and the second partition of the current block is reconstructed based on the second prediction mode.
