Claim of US Patent No. 10,298,903

1. A method of rendering a first part of an immersive video content having a field of view wider than a field of view of a user, the method comprising:obtaining parameters from at least one controller, said parameters being representative of a first part to render, said first part being a part of the immersive content corresponding to the field of view of the user;
determining a first distance between said first part and at least one reference part of the immersive video content;
processing a version of said first part, called degraded version, by degrading a visual quality of said first part according to said first distance, the greater the first distance, the higher the level of the visual degradation; and
rendering said degraded version of the first part; wherein
said first distance is:
an Euclidian distance between a center of said first part and a center of said at least a reference part, or
the shortest Euclidian distance among a set of distances between any point of said at least a reference part and any point of said first part, or
an average Euclidian distance of distances between any point of said at least a reference part and any point from said first part.
