Claim 5:
6. The video decoding apparatus of claim 1, wherein
the decoder is further configured to:
decode a first syntax element indicating whether derivation of the second residual samples is allowed from a sequence parameter set (SPS) level of the bitstream; and
decode a second syntax element indicating whether the derivation of the second residual samples is applied to the chroma block from a level lower than the SPS level in the bitstream when the first syntax element indicates that the derivation of the second residual samples is allowed, and

the chroma component reconstruction unit is further configured to derive the second residual samples when the second syntax element indicates that the derivation of the second residual samples is applied to the chroma block.
