Abstract: Systems and methods for identifying three dimensional (3D) content to stream. A method includes receiving information indicating a view field of a client device and identifying an amount of bandwidth available to stream the 3D content to the client device. The method includes assigning, for one or more of the objects, the bandwidth by, for each of the objects: determining whether the each object is within the view field of the client device based on a position of the each object; assigning a greater amount of the bandwidth to objects at least partially within the view field. The method includes streaming the 3D content to the client device according to the assigned bandwidth.

Abstract: An electronic device, a server and a method for packing and consuming video content are disclosed. The electronic device includes a sensor, a processor operably connected to the sensor, and a transceiver operably connected to the processor. The processor is configured to determine a current viewport for video content based on an output of the sensor. The transceiver is configured to request and receive a media stream including (i) a high-resolution video partition of the video content that covers the current viewport and (ii) a low-resolution version of the video content that is rotated relative to the video content. The processor is further configured to process the package to render at least one of the high-resolution video partition of the video content or the low-resolution version of the video content. The high-resolution video partition and the low-resolution video of the video content are packed together.
