Abstract
A method for decoding a coded data stream representing a video having a first view and a second view different from the first view, in which a reference image of the second view is previously reconstructed. For a current block of a current image of the first view, a motion information item associated with the current block representative of a displacement of the current block in the previously reconstructed reference image, is obtained. A prediction block is obtained based on the previously reconstructed reference image of the second view and of the obtained motion information item. The current block is reconstructed based on the prediction block, a prediction residual information item decoded based on the coded data stream and a difference information item calculated between a first block associated with the first view and a second block associated with the second view and decoded based on the coded data stream.
