Abstract
A decoding method is disclosed that comprises:—decoding (S120) a stream to obtain a decoded standard dynamic range picture and colour metadata associated with the standard dynamic range picture, wherein the colour metadata are representative at least of characteristics of a high dynamic range picture associated with the standard dynamic range picture; and—reconstructing (S130) a high dynamic range access the input stream(s) picture from the decoded standard dynamic range picture and from the colour metadata.
