CODING AND DECODING METHODS OF A PICTURE BLOCK, CORRESPONDING DEVICES AND DATA STREAM

摘要

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;
- reconstructing (16) the picture block from at least the special reference picture, wherein the at least the special reference picture is not displayed.
