Abstract
A method for decoding a data stream representing a multi-view video, including coded data representative of at least one sub-image, including texture data and depth data associated with the texture data, the sub-image including at least one zone, referred to as a useful zone, for generating an image of a view. An indicator is decoded, indicating whether the sub-image is coded according to a first method or a second method. When the indicator indicates that the sub-image is coded according to the first method, a binary map is decoded indicating for at least one pixel of the sub-image whether the pixel belongs to the useful zone. The texture and depth data of the sub-image are decoded, when the indicator indicates that the sub-image is coded according to the second method, the depth data of the sub-image for the pixels situated outside the useful zone including a decoded depth value.
