US Patent 11863744 Context modeling for spilt flag

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 receives coded information of a current coding tree unit (CTU) from a coded video bitstream, and determines a context model for a split flag associated with a current block within the current CTU at least partially based on split information of a corresponding block in a reference CTU for the current CTU. Then, the processing circuitry determines the split flag based on the context model, and decodes the current block based on the split flag that is determined based on the context model.
