Claim Text:
1. A video decoding apparatus, comprising: a first decoding circuit, realized with an entropy decoding circuit, the first decoding circuit comprising: a first decoding unit, configured for decoding a first encoded block to generate first residual values, wherein the first residual values are directly outputted from the first decoding unit; and a first detecting unit, only when a coded block pattern (CBP) bit corresponding to the first encoded block is equal to one, the first detecting unit is activated to detect whether all of the first residual values have a same first value; a first processing circuit, coupled to the first decoding unit and configured for processing the first residual values to generate first processed residual values; and a second processing circuit, coupled to the first processing circuit and the first detecting unit, wherein when the first detecting unit detecting all of the first residual values have the same first value, the second processing circuit is configured for generating a decoded block corresponding to the first encoded block by skipping processing the first residual values.
