Method and apparatus for video coding
Aspects of the disclosure provide methods and apparatuses for video coding. In the method, a bit stream including syntax elements is received. The syntax elements correspond to residues of a transform block in a coded picture. A first maximum number of context-coded bins of the syntax elements of a first coefficient sub-block in the transform block is determined based on a frequency position of the first coefficient sub-block. Each of a number of bins of the syntax elements of the first coefficient sub-block is coded according to a context model and the determined first maximum number. Coded bits of the number of the bins of the syntax elements of the first coefficient sub-block are decoded based on the context models. Further, the first maximum number is different from a second maximum number of context-coded bins of the syntax elements of a second coefficient sub-block in the transform block.
