Abstract

Set-top box circuitry and methods of operating the same are described that support the delivery of media content between one or more media content sources and a screen assembly of a display system. The set-top box circuitry is configured to process media content having display requirements that exceed constraints associated with a viewing environment that includes the screen assembly to produce processed media content having display requirements that do not exceed the constraints. The set-top box circuitry may also be configured to obtain substitute media content that replaces requested media content when the requested media content has display requirements exceeding constraints associated with a media content source, a communication path from the media content source, and/or the viewing environment.

Claims

1. Set top box circuitry supporting media delivery between one or more media content sources and a screen assembly, the screen assembly having a viewing limitation, the set top box circuitry comprising:

one or more media interfaces, each of the one or more media interfaces suitable for connection to at least one of the one or more media content sources;

a display device interface suitable for connection to the screen assembly;

a first of the one or more media interfaces being operable to receive first media content from a first of the one or more media content sources, the first media content having at least a first display requirement, the first media content being first three-dimensional media content; and

processing circuitry operable to process the first media content in a manner that is based at least in part upon the viewing limitation of the screen assembly to yield second media content having at least a second display requirement, the second display requirement being within the viewing limitation of the screen assembly.

2. The set top box circuitry of claim 1, wherein the second media content comprises two-dimensional media content.

4. The set top box circuitry of claim 3, wherein the second three-dimensional media content differs by having a lesser number of perspective views than that of the first three-dimensional media content.

5. The set top box circuitry of claim 3, wherein the second three-dimensional media content differs by having a lesser resolution than that of the first three-dimensional media content.

6. The set top box circuitry of claim 3, wherein the second three-dimensional media content differs by being configured for display within a region of the screen assembly while the first three-dimensional media content is configured for full screen display on the screen assembly.

7. The set top box circuitry of claim 1, wherein the processing circuitry causes a reconfiguration of a region of the screen assembly, and the processing circuitry delivers via the display interface the second three-dimensional media content for display within the region.

8. The set top box circuitry of claim 1, wherein the viewing limitation comprises at least in part a factory limitation.
