  • Publication number: 20200314448
    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. The maximum transform size is used in a partition to form, from the residues, one or more transform blocks that are respectively encoded into the bits. Then, the processing circuitry reconstructs based on the maximum transform size and from the bits the residues associated with the prediction of the block, and then the processing circuitry reconstructs samples of the block based on the reconstructed residues and the prediction of the block.
