Abstract
Apparatuses and methods for encoding or decoding picture information that involve determining a scaling factor to scale a chroma prediction residual associated with chroma information included in the picture information; scaling the chroma prediction residual based on the scaling factor to provide a scaled chroma prediction residual; and encoding or decoding at least a portion of the picture information based on the scaled chroma prediction residual.
