determining, based on information extracted from an encoded data stream, a first residual signal relating to a first component of the multi-component picture;

extracting, from the encoded data stream, a signaling syntax element that indicates whether or not a second residual signal of a second component of the multi-component picture is derived based on the first residual signal such that either (a) a portion of the first residual signal is scaled using a scaling factor to derive a portion of the second residual signal, or (b) a correction signal is extracted from the encoded data stream independent of the first residual signal to derive a portion of the second residual signal;

responsive to the signaling syntax element, deriving the portion of the second residual signal;

sub-dividing the multi-component picture into prediction blocks and residual blocks, and further subdivide the residual blocks into transform blocks;

selecting prediction modes based on first information from the encoded data stream;

determining prediction parameters for the prediction blocks based on second information from the encoded data stream;

deriving a prediction signal using the prediction modes and the prediction parameters;

deriving a residual signal within each residual block by performing inverse transformations within the transform blocks; and

reconstructing the multi-component picture by combining the prediction signal and the residual signal.
