Abstract (en)

[origin: WO2019076764A1] The invention relates to a method for encoding and to a device for encoding a data flow representing an omnidirectional video, and, correlatively, to a method for decoding and to a device for decoding a data flow representing an omnidirectional video. According to the invention, the data flow representing an omnidirectional video comprises data encoded with at least one base layer representing a 2D or 3D video representing a view of a scene captured by the omnidirectional video, and data encoded with at least one enhancement layer representing the omnidirectional video, the at least one enhancement layer being predictively encoded in relation to the at least one base layer.
