Abstract: The invention concerns 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 of the invention comprises, applying to a current image which contains at least one area which is to be reconstructed, the steps of: obtaining (E605) 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 (E606) at least part of said at least one area using the projected residual data obtained.

Abstract: The video coding method comprises a step (1001) of determining a motion vector for each of a plurality of blocks of a picture from a reference picture. The method then performs a step (1006 to 1010) of selecting at least one first block in said plurality of blocks, according to the difference between a first motion vector and a second motion vector, wherein the first motion vector is the motion vector associated with said first block, and the second motion vector is a motion vector relating to a second block, which second block is located in the same picture at a position relative to the first block determined by the first motion vector. The method then performs a step (1012) of coding at least one non-selected block with a first coding mode, and a step (1012) of coding at least one first selected block with a second coding mode different from the first coding mode.
