Method for decoding a coded data signal which is representative of a multi-view video sequence which is representative of an omnidirectional video, the multi-view video sequence comprising at least a first view and a second view, the decoding method comprising the following steps: - reading, from the data signal, parameters making it possible to obtain a homographic matrix which is representative of the transformation from a plane of the second view to a plane of the first view, - decoding an image of the second view, the image of the second view comprising a region referred to as an active region comprising pixels which, when said pixels are projected via the homographic matrix onto an image of the first view, are contained in the image of the first view, decoding the image of the second view comprising: - generating a reference image comprising pixel values determined on the basis of previously reconstructed pixels of an image of the first view and of the homographic matrix, and - for at least one block of the image of the second view: - reading, from the data signal, an index which is representative of a reference image contained in a list of reference images comprising at least one image of the second view reconstructed previously, the list of reference images comprising the generated reference image, when it has been determined that at least one portion of said block belongs to the active region, the list of reference images not comprising the generated reference image; otherwise, - reconstructing said at least one portion of said block or said block on the basis of said reference image indicated by the read index. - reading, from the data signal, parameters making it possible to obtain a homographic matrix which is representative of the transformation from a plane of the second view to a plane of the first view, - decoding an image of the second view, the image of the second view comprising a region referred to as an active region comprising pixels which, when said pixels are projected via the homographic matrix onto an image of the first view, are contained in the image of the first view, decoding the image of the second view comprising: - generating a reference image comprising pixel values determined on the basis of previously reconstructed pixels of an image of the first view and of the homographic matrix, and - for at least one block of the image of the second view: - reading, from the data signal, an index which is representative of a reference image contained in a list of reference images comprising at least one image of the second view reconstructed previously, the list of reference images comprising the generated reference image, when it has been determined that at least one portion of said block belongs to the active region, the list of reference images not comprising the generated reference image; otherwise, - reconstructing said at least one portion of said block or said block on the basis of said reference image indicated by the read index. - generating a reference image comprising pixel values determined on the basis of previously reconstructed pixels of an image of the first view and of the homographic matrix, and - for at least one block of the image of the second view: - reading, from the data signal, an index which is representative of a reference image contained in a list of reference images comprising at least one image of the second view reconstructed previously, the list of reference images comprising the generated reference image, when it has been determined that at least one portion of said block belongs to the active region, the list of reference images not comprising the generated reference image; otherwise, - reconstructing said at least one portion of said block or said block on the basis of said reference image indicated by the read index. - reading, from the data signal, an index which is representative of a reference image contained in a list of reference images comprising at least one image of the second view reconstructed previously, the list of reference images comprising the generated reference image, when it has been determined that at least one portion of said block belongs to the active region, the list of reference images not comprising the generated reference image; otherwise, - reconstructing said at least one portion of said block or said block on the basis of said reference image indicated by the read index.
