A method comprising decoding one or both chroma components of a coded texture picture into one or two decoded chroma sample arrays, obtaining a reference sample array on the basis of said one or two decoded chroma sample arrays, and forming a decoded depth view component on the basis of said reference sample array; encoding one or two chroma components of a texture picture into one or two coded chroma components and reconstructing one or two reconstructed chroma sample arrays, obtaining a reference sample array on the basis of said one or two reconstructed chroma sample arrays, and using the reference sample array as a reference for prediction in encoding of a depth view component.
