1. A method of rendering immersive video content, the method comprising:

rendering by a device, using received cell data, a first viewpoint corresponding to a first user position in the immersive video, the first user position being in a first area covered by a first cell, the received cell data representing the first cell;

wherein the received cell data comprises parallax information of the first cell, an identifier of a neighboring cell covering a second area, and content of a central patch of the neighboring cell corresponding to the identifier, wherein the central patch comprises a part of a scene visible from a central viewpoint of the neighboring cell, wherein the first cell is a patch only (PO) cell for which the cell data is smaller than cell data of the neighboring cell; and

wherein the first viewpoint is generated from the content of the central patch and the parallax information.
