Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry receives a bitstream including bits corresponding to residues associated with a prediction of a block in a coding tree unit (CTU) and determines a maximum transform size based on the CTU size.
