Abstract
A method for encoding a data stream representing an omnidirectional video. The method includes: encoding, in the stream, at least one base layer representative of a 2D or 3D video, the 2D or 3D video being representative of a view of a same scene captured by the omnidirectional video; and encoding, in the stream, one enhancement layer representative of the omnidirectional video. The enhancement layer is encoded by prediction relative to the base layer. The prediction of the enhancement layer relative to the base layer includes: generating a reference sub-image obtained by geometrical projection on the reference sub-image of an image, called a base image, rebuilt from the base layer, and storing the reference sub-image in association with shift information enabling an encoder to determine the location of the reference sub-image in the enhancement image in a non-transitory computer-readable memory of reference sub-images of the enhancement layer.
