System and methods for buffering of real-time data streams

1. A computer-implemented method comprising:

transmitting a request, at a user device, to a content server for an initial content quality type associated with a content stream, the initial content quality type corresponding to an initial speed at which the user device is able to consume the content stream;

receiving, at the user device, the content stream with the initial content quality type directly from a content feed, the content stream not being stored at the content server, the content feed being located at a site different from the content server;

detecting, at the user device, a low watermark condition as the content stream is played on the user device;

discovering, at the user device, an available bandwidth associated with the content feed;

transmitting a request, at the user device, to the content server, based on the discovered available bandwidth of the content feed, for a modified content quality type associated with the content stream while receipt of the content stream is in progress; and

receiving, at the user device, the content stream with the modified content quality type from the content feed, the modified content quality type corresponding to a different speed at which the user device is able to consume the content stream.

2. The computer-implemented method as claimed in claim 1 including detecting a high watermark condition as the content stream is played on the user device; and requesting the content server for the initial content quality type associated with the content stream while streaming of the content stream is in progress.

3. The computer-implemented method as claimed in claim 1 including negotiating with the content server for a content quality type compatible with the content stream and compatible with the available bandwidth associated with the content feed.

4. The computer-implemented method as claimed in claim 1 including configuring an initial incoming data speed (Si), an initial playback speed (Sp), an initial buffer size (B), and initial high and low watermarks.

5. The computer-implemented method as claimed in claim 1 including filling a content buffer with the content stream to a location indicated by a high watermark.

6. An apparatus comprising:

a user device; and

a buffer manager, at the user device, the buffer manager being configured to:

transmit a request to a content server for an initial content quality type associated with a content stream, the initial content quality type corresponding to an initial speed at which the user device is able to consume the content stream;

receive the content stream with the initial content quality type directly from a content feed, the content stream not being stored at the content server, the content feed being located at a site different from the content server;

detect a low watermark condition as the content stream is played on the user device;

discover an available bandwidth associated with the content feed;

transmit a request to the content server, based on the discovered available bandwidth of the content feed, for a modified content quality type associated with the content stream while receipt of the content stream is in progress; and

receive the content stream with the modified content quality type from the content feed, the modified content quality type corresponding to a different speed at which the user device is able to consume the content stream.

7. The apparatus as claimed in claim 6 being further configured to detect a high watermark condition as the content stream is played on the user device; and reconfigure the content server for the initial content quality type associated with the content stream while streaming of the content stream is in progress.

8. The apparatus as claimed in claim 6 being further configured to negotiate with the content server for a content quality type compatible with the content stream and compatible with the available bandwidth associated with the content feed.

9. The apparatus as claimed in claim 6 being further configured to configure an initial incoming data speed (Si), an initial playback speed (Sp), an initial buffer size (B), and initial high and low watermarks.

10. The apparatus as claimed in claim 6 being further configured to fill a content buffer with the content stream to a location indicated by a high watermark.

11. An article of manufacture comprising a non-transitory machine readable storage medium having machine executable instructions embedded thereon, which when executed by a user device, cause the user device machine to:

transmit a request to a content server for an initial content quality type associated with a content stream, the initial content quality type corresponding to an initial speed at which the user device is able to consume the content stream;

receive the content stream with the initial content quality type directly from a content feed, the content stream not being stored at the content server, the content feed being located at a site different from the content server;

detect a low watermark condition as the content stream is played on the user device;

discover an available bandwidth associated with the content feed;

transmit a request to the content server, based on the discovered available bandwidth of the content feed, for a modified content quality type associated with the content stream while receipt of the content stream is in progress; and

receive the content stream with the modified content quality type from the content feed, the modified content quality type corresponding to a different speed at which the user device is able to consume the content stream.
