摘要：
A video decoding method includes: before residual decoding of a coding unit is completed, referring to available information to determine whether to decode information that an inverse transform (IT) circuit needs for applying inverse transform to transform blocks of the coding unit, and generating a determination result; and controlling coefficient transmission of the coding unit to the IT circuit according to the determination result.
