1. An apparatus for providing 360° media content to a plurality of receivers, wherein the apparatus is to
acquire for a representation of the 360° media content a first plurality of tiles, the first plurality of tiles covering a part of or the whole representation of the 360° media content,
for some or all of the plurality receivers, transmit to each receiver the first plurality of tiles and a second plurality of tiles,
wherein the second plurality of tiles cover for a respective receiver only a viewport in the representation of the 360° media content,
wherein the second plurality of tiles overlaps the first plurality of tiles, and
wherein, responsive to viewport information from a receiver, the apparatus is to encode the second plurality of tiles corresponding to the viewport in the representation of the 360° media content in a quality or resolution being higher than a quality or resolution for the first plurality of tiles.
