Zusammenfassung:.A method for decoding a picture block is disclosed. The decoding method comprises: - decoding (10) at least one stream S_diff into decoded data and into one information for identifying a reconstructed reference picture in a decoder picture buffer; - reconstructing (12) a special reference picture from at least the identified reconstructed reference picture and from the decoded data ; - replacing (14) in the decoder picture buffer one reconstructed reference picture by the special reference picture; and - reconstructing (16) the picture block from at least the special reference picture.
