Patent ID: 11677969

Abstract:
Aspects of the disclosure provide methods and an apparatus including processing circuitry that decodes coded information of a coding block (CB) in a picture from a coded video bitstream. The coded information indicates a width W and a height H of the CB. The processing circuitry partitions the CB into sub-processing units (SPUs) having a width being a minimum one of W and K and a height being a minimum one of H and K. At least one of the width W and the height H is larger than a processing data unit size K. The processing circuitry determines a partitioning structure to partition the SPUs based on the width, the height, and a maximum transform unit (TU) size M. At least one of the width and the height is larger than M. The processing circuitry partitions each of the SPUs into TUs of M×M based on the partitioning structure.
