Abstract
Aspects of the subject disclosure may include, for example, a device in which a processing system receives from a multimedia content server a plurality of content streams; each of the content streams includes a portion of an original content stream. The processing system transcodes the plurality of content streams based on a viewport prediction to produce a plurality of viewport streams; the viewport prediction is based at least in part on a visibility map associated with a viewer of the content. The processing system delivers each of the viewport streams to a client device associated with the viewer; each of the viewport streams is buffered at the client device in a separate buffer. Other embodiments are disclosed.
