Abstract

Methods and systems related to processing multiple data transmissions are disclosed. For example, a computing device may receive a data stream corresponding to a content item, and generate additional data streams by sampling the data stream, for example, using different sampling regions. Another data stream at a higher resolution than each of the additional data streams may then be generated by combining elements (e.g., pixels) of the additional data streams.

Claims (52)

1. A method comprising:

receiving, by a computing device, a content item comprising a first plurality of pixels at a first resolution;

encoding the content item into:

a first data stream comprising a first subset of the first plurality of pixels, and

a second data stream comprising a second subset of the first plurality of pixels, wherein the first subset and the second subset are configured to be interleaved to form a second plurality of pixels of the content item at a second resolution, and wherein the encoding comprises:

comparing a bits per pixel value of the first data stream and a bits per pixel value of the second data stream; and

based on the comparing, maintaining a bits per pixel value of the first data stream within a threshold of a bits per pixel value of the second data stream;

receiving, from a user device, a request for the content item at the second resolution; and

sending, to the user device, the first data stream and the second data stream.

2. The method of claim 1 , wherein the first data stream is encoded by downsampling the first plurality of pixels.

3. The method of claim 1 , wherein the first subset of the first plurality of pixels is different from the second subset of the first plurality of pixels.

4. The method of claim 1 , wherein the first data stream and the second data stream are scaled prior to the sending.

5. The method of claim 1 , further comprising:

causing, by the computing device, the user device to render a presentation of the content item at the second resolution based on combining the first data stream and the second data stream.

6. The method of claim 1 , further comprising:

causing, by the computing device, the user device to render a presentation of the content item at the second resolution based on combining the first data stream and the second data stream; and

adjusting, via quantization, a bit rate of the presentation of the content item.

7. The method of claim 1 , further comprising:

causing, by the computing device, the user device to render a presentation of the content item at the second resolution based on combining the first data stream and the second data stream; and

adjusting, via one or more motion vectors, a bit rate of the presentation.

8. The method of claim 1 , further comprising:

generating the first data stream by averaging the first subset of the first plurality of pixels; and

generating the second data stream by downsampling the second subset of the first plurality of pixels.

9. A method comprising:

receiving information comprising a plurality of pixels for a content item;

encoding a plurality of data streams for the content item, wherein the plurality of data streams comprises:

a first data stream comprising the content item at a first resolution, wherein the first data stream is encoded at a bits per pixel rate;

a second data stream comprising the content item at a second resolution, wherein the second data stream is encoded at the same bits per pixel rate as the first data stream, wherein the first data stream and the second data stream are configured to be interleaved to form a third data stream at a third resolution that is greater than the first and second resolutions; and

sending, to a user device, the first data stream and the second data stream.

10. The method of claim 9 , wherein the second data stream is encoded by averaging a subset of the plurality of pixels.

11. The method of claim 9 , wherein the first data stream is encoded by downsampling the plurality of pixels, and wherein the second data stream is encoded by downsampling the plurality of pixels.

12. The method of claim 9 , further comprising:

causing the user device to render a presentation of the content item at the third resolution based on combining the first data stream and the second data stream.

13. The method of claim 9 , further comprising:

causing the user device to adjust a resolution of the first data stream and the second data stream prior to combining the first data stream and the second data stream.

14. The method of claim 9 , wherein the first data stream comprises pixels from a first region corresponding to the plurality of pixels, wherein the second data stream comprises pixels from a second region corresponding to the plurality of pixels, and wherein the first region overlaps with the second region.

15. The method of claim 9 , wherein the first data stream is encoded by averaging one or more of the plurality of pixels, and wherein the second data stream is encoded by downsampling one or more of the plurality of pixels.

16. The method of claim 9 , wherein the second resolution is lower than the first resolution.

17. A method comprising:

receiving information related to a plurality of pixels of a content item associated with a first resolution;

accessing a plurality of data streams comprising:

a first data stream comprising a first subset of the plurality of pixels; and

a second data stream comprising a second subset of the plurality of pixels, wherein the first subset of the plurality of pixels and the second subset of the plurality of pixels are configured to be interleaved to form the content item at a second resolution of a user device; and

sending, to the user device, the first data stream and the second data stream, wherein the first data stream and the second data stream are maintained within a threshold bits per pixel rate.

18. The method of claim 17 , further comprising:

encoding the first data stream by averaging the first subset of the plurality of pixels; and

encoding the second data stream by downsampling the second subset of the plurality of pixels.

19. The method of claim 17 , wherein the second resolution is lower than the first resolution.

20. The method of claim 17 , further comprising:

receiving, from the user device, a request for a third data stream at a third resolution;

generating, based on the first data stream and the second data stream, the third data stream; and

sending the third data stream to the user device.
