1. A method for decoding a video sequence encoded according to a predictive format, which video sequence includes predicted images containing encoded residual data representing differences between the respective predicted image and a respective reference image in the video sequence, the method applied to a current image which contains at least one area which is to be reconstructed, comprising: obtaining projected residual data for said at least one area to be reconstructed, from residual data of at least one image predicted from the current image, corresponding to a temporal projection of at least part of the at least one area to be reconstructed onto said at least one image predicted from the current image; and reconstructing at least part of said at least one area to be reconstructed using the projected residual data obtained.
