Classification: CPC H | IPC H

Claim 8:
9. A video decoding apparatus comprising:
an entropy decoding circuit, arranged to perform residual decoding of a coding unit;
an inverse transform (IT) circuit, arranged to apply inverse transform to transform blocks of the coding unit; and
an inverse scan (IS) circuit, coupled between the entropy decoding circuit and the IT circuit, and arranged to re-order coefficients of the coding unit;
wherein before the residual decoding of the coding unit is completed, at least one of the entropy decoding circuit and the IS circuit is arranged to determine whether the entropy decoding circuit needs to decode information that the IT circuit needs for applying the inverse transform to the transform blocks of the coding unit, to generate a determination result, and is further arranged to control coefficient transmission of the coding unit to the IT circuit according to the determination result.
