摘要：
The present disclosure relates to a method and apparatus for coding a plurality of 2D pictures representative of picture data of an omnidirectional video into a bitstream, at least one of the 2D picture of said plurality of 2D pictures is predictive-coded using at least one 2D reference picture, characterized in that the method comprises:
- when at least one coded 2D picture of said plurality of 2D pictures is used as reference for predictive-coding;
- packing a decoded version of each of all the coded 2D pictures into a composite frame leaving room between said decoded versions and between the border of said composite frame and some of said decoded versions; and
- spatially extending each of said decoded version independently of each other.
- when at least one coded 2D picture of said plurality of 2D pictures is used as reference for predictive-coding;
- packing a decoded version of each of all the coded 2D pictures into a composite frame leaving room between said decoded versions and between the border of said composite frame and some of said decoded versions; and
- spatially extending each of said decoded version independently of each other.
