Abstract
In order to reduce the large volume of data transmitted over a network, immersive videos are frequently represented by a multiple versions, each version being optimised in terms of quality for a point of view on the immersive video, the immersive video parts not representing the point of view for which the version was optimised being of lower quality. In this context, when a user using suitable viewing equipment views the immersive video, he must change version whenever he changes point of view. Each version is generally stored on a server relatively distant from the viewing equipment, which may give rise to latencies in the reception of a new version following a change of point of view. This latency time is reduced by allowing a node in the intermediate network between the server and the viewing equipment to transmit each version to the equipment in place of the server.
