An embodiment of the invention allows for new, bandwidth-efficient communications protocols to be executed across existing standardized physical interface hardware, thereby allowing for easier acceptance of the new protocols within the consumer electronics industry.

Abstract: Example embodiments provide systems and methods for managing intelligent content queuing from a secondary device for content delivery to a primary device. A content queuing system on the secondary device generates and displays a playlist interface on the secondary device. A selection of a content item to be added to a playlist is received. The content queuing system determines that addition of the content item causes a live content item to overlap with an on-demand content item on the playlist. As a result, the content queuing system creates at least two segments for the on-demand content item. The live content item is positioned between the first and a second segment on the playlist. The first segment is scheduled to end at a start time of the live content item and the second segment is scheduled to begin at an ending time of the live content item.

Abstract: The disclosure provides methods and content consumption devices that enable a scene, for example a 360° scene, that is larger (i.e. has more pixels in at least one dimension) than a display format of the content consumption device to be displayed. Constituent scene views are received individually by the content consumption device, for example as broadcasts, and are combined, for example stitched together, at the content consumption device to output a part of the scene that fits in the display format. The part of the scene (and hence the required constituent streams) to be displayed are determined by a signal, for example a navigational input from a user, enabling the user to navigate in the scene. By, for example, receiving a limited number of scene streams based on the scene streams required to produce the view that fits in the display format based on the signal, bandwidth requirements to view and navigate within the scene.
