Method and device for sequence decoding with error concealment

A non-transitory computer-readable storage medium storing a program which, when executed by a computer or a processor in a device for decoding a video sequence, causes the device to carry out a method for decoding a video sequence encoded according to a predictive format, the video sequence including 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 due to loss or corruption of data corresponding to the at least one area of the current image, comprising:

• obtaining projected residual data for said at least one area to be reconstructed from residual data of at least one image which is predicted from the current image and is temporally later in the video sequence than the current image, the projected residual data 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.
