Abstract
Aspects of the subject disclosure may include, for example, a method comprising obtaining media content; receiving a request from equipment of a user to view the media content; identifying a predicted field of view of the user; sending a base layer of the media content to the equipment of the user using a first stream; and sending a first enhancement layer of the predicted field of view to the equipment of the user using a second stream. The first stream and the second stream may utilize different protocols, different servers, different buffer sizes, and/or a combination thereof. While the first stream may include an entire 360 degrees of the base layer of the media content, the second stream may be limited to the first enhancement layer of the predicted field of view of the media content.
