Abstract

A computer-implemented method performed by a server including obtaining a stream of live data comprising a plurality of segments; storing the plurality of segments to form a recorded stream; transmitting the plurality of segments as a near-live feed to one or more nodes in a network; transmitting the recorded stream to another node in the network; and transitioning from transmission to the another node of the recorded stream to the near-live feed, the transmission comprising: delaying transmission of the near-live feed to the another node until a new segment of the stream of live data is obtained.

Claims

1. A computer-implemented method performed by a server, the method comprising:

obtaining a stream of live data comprising a plurality of segments;

storing the plurality of segments to form a recorded stream;

transmitting the plurality of segments as a near-live feed to one or more nodes in a network;

in response to a request for at least a portion of the stream of live data from another node after the transmitting the plurality of segments commenced, transmitting the recorded stream to the another node in the network; and

transitioning from transmission to the another node of the recorded stream to the near-live feed, the transmission comprising;

delaying transmission of the near-live feed to the another node until a new segment of the stream of live data is obtained.

2. The computer-implemented method of claim 1, wherein obtaining the stream of live data comprising the plurality of segments includes segmenting the stream of live data to form the plurality of segments.

3. The computer-implemented method of claim 1, wherein each segment of the plurality of segments is defined by a configurable interval, the configurable interval having an upper limit and a lower limit.

4. The computer-implemented method of claim 3, wherein the upper limit depends upon time and/or data size.

5. The computer-implemented method of claim 3, wherein the lower limit depends upon bitrate and/or content type or packaging.

6. The computer-implemented method of claim 1, wherein the transitioning occurs in response to a request for the near-live feed from the another node in the network.

7. The computer-implemented method of claim 1, wherein the network includes a multi-tier server architecture, the multi-tier server architecture including an origin server at a top level and one or more servers at a lower level, the origin server being connected to at least one of the one or more servers.

8. The computer-implemented method of claim 1, further comprising:

transitioning from transmission to the another node of the near-live feed to the recorded stream.

9. A computer-program product, encoded on a non-transitory computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

obtaining a stream of live data comprising a plurality of segments;

storing the plurality of segments to form a recorded stream;

transmitting the plurality of segments as a near-live feed to one or more nodes in a network;

in response to a request for at least a portion of the stream of live data from another node after the transmitting the plurality of segments commenced, transmitting the recorded stream to the another node in the network; and

transitioning from transmission to the another node of the recorded stream to the near-live feed, the transmission comprising;

delaying transmission of the near-live feed to the another node until a new segment of the stream of live data is obtained.

10. The computer-program product of claim 9, wherein obtaining the stream of live data comprising the plurality of segments includes segmenting the stream of live data to form the plurality of segments.

11. The computer-program product of claim 9, wherein each segment of the plurality of segments is defined by a configurable interval, the configurable interval having an upper limit and a lower limit.

12. The computer-program product of claim 11, wherein the upper limit depends upon time and/or data size.

13. The computer-program product of claim 11, wherein the lower limit depends upon bitrate and/or content type or packaging.

14. The computer-program product of claim 9, wherein the transitioning occurs in response to a request for the near-live feed from the another node in the network.

15. The computer-program product of claim 9, wherein the network includes a multi-tier server architecture, the multi-tier server architecture including an origin server at a top level and one or more servers at a lower level, the origin server being connected to at least one of the one or more servers.

16. The computer-program product of claim 9, further comprising:

transitioning from transmission to the another node of the near-live feed to the recorded stream.

17. A system performed by a server, the system comprising:

one or more nodes in a network; and

at least one server configured to perform operations, comprising;

obtaining a stream of live data comprising a plurality of segments;

storing the plurality of segments to form a recorded stream;

transmitting the plurality of segments as a near-live feed to the one or more nodes in the network;

in response to a request for at least a portion of the stream of live data from another node after the transmitting the plurality of segments commenced, transmitting the recorded stream to the another node in the network; and

transitioning from transmission to the another node of the recorded stream to the near-live feed, the transmission comprising;

delaying transmission of the near-live feed to the another node until a new segment of the stream of live data is obtained.

18. The system of claim 17, wherein obtaining the stream of live data comprising the plurality of segments includes segmenting the stream of live data to form the plurality of segments.

19. The system of claim 17, wherein each segment of the plurality of segments is defined by a configurable interval, the configurable interval having an upper limit and a lower limit.

20. The system of claim 19, wherein the upper limit depends upon time and/or data size.

21. The system of claim 19, wherein the lower limit depends upon bitrate and/or content type or packaging.

22. The system of claim 17, wherein the transitioning occurs in response to a request for the near-live feed from the another node in the network.

23. The system of claim 17, wherein the network includes a multi-tier server architecture, the multi-tier server architecture including an origin server at a top level and one or more servers at a lower level, the origin server being connected to at least one of the one or more servers.

24. The system of claim 17, wherein the operations further comprise:

transitioning from transmission to the another node of the near-live feed to the recorded stream.
