1. A method of managing media storage and delivery, comprising:
obtaining information about a three-dimensional (3D) scene;
obtaining, from the information, a parameter indicating that viewport adaptation is enabled,
wherein the parameter indicating that viewpoint adaptation is enabled indicates that a media bitrate of a timed media presentation is adjusted based on a range of a current viewport;
rendering the 3D scene, wherein the 3D scene includes at least one timed media to be reproduced within the 3D scene;
obtaining the current viewport of a user;
determining whether the at least one timed media is inside or outside of the range of the current viewport; and
reducing a bitrate of a first timed media among the at least one timed media based on a result of determining that the first timed media is outside the range of the current viewport.
