Abstract
A method of encoding and a device for encoding a data stream representative of an omnidirectional video and, correlatively, a method for decoding and a device for decoding a data stream representative of an omnidirectional video. The data stream is representative of an omnidirectional video and includes encoded data of at least one base layer representative of a 2D or 3D video representative of a view of a scene captured by the omnidirectional video, and encoded data of at least one enhancement layer representative of the omnidirectional video. The least one enhancement layer is encoded by prediction relative to the at least one base layer.
