Extended scene view
The disclosure provide 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.
1. A method of processing video streams at a content consumption device, the method comprising:
generating a plurality of video streams, each video stream of the plurality of video streams corresponding to a respective field of view of a scene, wherein the plurality of video streams are combinable into a combined stream corresponding to a field of view of the scene;
receiving an indication of an output portion of the scene to be output by the content consumption device, wherein the output portion corresponds to a reduced field of view, the reduced field of view being smaller than the field of view corresponding to the combined stream;
selecting two or more separate video streams of the plurality of video streams for an output video stream corresponding to the output portion, the output video stream corresponding to the reduced field of view; and
sending the output video stream to a content consumption device.
2. The method of claim 1 , wherein the reduced field of view fits in a display format for the content consumption device.
3. The method of claim 1 , wherein the two or more separate video streams correspond to a respective overlapping portion of the scene, wherein each overlapping portion overlaps the output portion.
4. The method of claim 1 , wherein the two or more separate video streams are broadcast.
5. The method of claim 1 , wherein selecting the two or more separate video streams comprises receiving a respective broadcast of each of the two or more separate video streams.
6. The method of claim 1 , wherein at least one of the plurality of video streams is broadcast on a first broadcast channel and at least one other of the plurality of video streams is broadcast on a second broadcast channel different from the first broadcast channel.
7. The method of claim 1 , wherein the indication of the output portion comprises a signal received from the content consumption device.
8. The method of claim 1 , further comprising:
receiving data identifying the plurality of video streams as related to the scene; and
identifying one or more adjacent video streams adjacent in the scene to each video stream of the plurality of video streams.
9. The method of claim 8 , further comprising selecting the two or more separate video streams based on identifying the one or more adjacent video streams.
10. The method of claim 8 , wherein the data is embedded in each video stream of the plurality of video streams.
11. A device processing video streams at a content consumption device, the device comprising:
a memory configured to store video data associated with one or more video streams; and
a processor configured to:
generate a plurality of video streams, each video stream of the plurality of video streams corresponding to a respective field of view of a scene, wherein the plurality of video streams are combinable into a combined stream corresponding to a field of view of the scene;
obtain an indication of an output portion of the scene to be output by the content consumption device, wherein the output portion corresponds to a reduced field of view, the reduced field of view being smaller than the field of view corresponding to the combined stream;
select two or more separate video streams of the plurality of video streams for an output video stream corresponding to the output portion, the output video stream corresponding to the reduced field of view; and
send the output video stream to a content consumption device.
12. The device of claim 11 , wherein the reduced field of view fits in a display format for the content consumption device.
13. The device of claim 11 , wherein the two or more separate video streams correspond to a respective overlapping portion of the scene, wherein each overlapping portion overlaps the output portion.
14. The device of claim 11 , wherein the two or more separate video streams are broadcast.
15. The device of claim 11 , wherein, to select the two or more separate video streams, the processor is configured to obtain a respective broadcast of each of the two or more separate video streams.
16. The device of claim 11 , wherein at least one of the plurality of video streams is broadcast on a first broadcast channel and at least one other of the plurality of video streams is broadcast on a second broadcast channel different from the first broadcast channel.
17. The device of claim 11 , wherein the indication of the output portion comprises a signal received from the content consumption device.
18. The device of claim 11 , wherein the processor is configured to:
obtain data identifying the plurality of video streams as related to the scene; and
identify, based on the data, one or more adjacent video streams adjacent in the scene to each video stream of the plurality of video streams.
19. The device of claim 18 , wherein the processor is configured to select the two or more separate video streams based on identifying the one or more adjacent video streams.
20. The device of claim 18 , wherein the data is embedded in each video stream of the plurality of video streams.
