Abstract
A method for processing multi-view video data including, for at least one block of an image of a view encoded in an encoded data stream representing the multi-view video, obtaining at least one information item, which specifies a mode for obtaining a synthesis data item, from among first and second obtaining modes. The synthesis data item is used to synthesize at least one image of an intermediate view of the multi-view video, the intermediate view not being encoded in the encoded data stream. The first obtaining mode involves decoding an information item representing the synthesis data item from the encoded data stream, the second obtaining mode involves obtaining the synthesis data item from at least the reconstructed encoded image. At least one part of an image of the intermediate view is synthesised from at least the reconstructed encoded image and the synthesis data item obtained by the specified mode.
