Abstract

Systems and methods for rapid content switching between pieces of content presented in a plurality of stations using streaming content distribution in accordance with embodiments of the invention are disclosed. One embodiment includes processing a portion of a station manifest that includes identifiers for content stations and identifiers for pieces of content associated with content stations, selecting jump points that are associated with specific locations within pieces of content, determining a current content station, playing a portion of a current piece of content associated with the current content station, determining alternative pieces of content using the station manifest, preparing additional content for playback at each of the jump points by preparing alternative pieces of content during playback of the current content, receiving a user instruction during playback, selecting a target jump point based upon the user instruction, and commencing playback of additional content starting from the target jump point.

Claims

1. A method for rapid content switching between pieces of content presented in a plurality of stations using streaming content distribution, comprising:

processing at least a portion of a station manifest using a playback device, where the station manifest comprises;

identifiers for a plurality of content stations; and

identifiers for a plurality of pieces of content, where each piece of content is associated with at least one content station;

selecting a plurality of jump points using the playback device, where each jump point is associated with a specific location within a piece of content;

determining a current content station from the plurality of content stations using the playback device;

playing at least a portion of a current piece of content associated with the current content station from the plurality of pieces of content using the playback device;

determining a plurality of alternative pieces of content from the plurality of pieces of content using the station manifest using the playback device;

preparing additional content for playback at each of the plurality of jump points by preparing alternative pieces of content during playback of the current piece of content using the playback device;

receiving a user instruction during playback of the current piece of content using the playback device;

selecting a target jump point from the plurality of jump points based upon the received user instruction using the playback device; and

commencing playback of prepared additional content starting from the selected target jump point using the playback device.

2. The method of claim 1, wherein the selected target jump point is associated with a specific location within an alternative piece of content.

3. The method of claim 1, wherein the selected target jump point is associated with a specific location within the current piece of content.

4. The method of claim 1, wherein preparing additional content for playback comprises buffering at least a portion of each of the plurality of alternative pieces of content using the playback device.

5. The method of claim 4, wherein buffering at least a portion of at least some of the plurality of alternative pieces of content using the playback device comprises buffering alternative content starting from a jump point in each alternative piece of content.

6. The method of claim 5, further comprising determining the likelihood that certain jump points will be selected by a user instruction and wherein buffering alternative content starting from a jump point in each alternative piece of content further comprises buffering a stream of the alternative piece of content whose bitrate is related to the likelihood a jump point in the alternative piece of content will be selected.

7. The method of claim 5, wherein the number of jump points at which alternative content is buffered and the bitrate of the alternative content that is buffered are related to the current available bandwidth.

8. The method of claim 1, wherein preparing additional content for playback further comprises preparing the current piece of content.

9. The method of claim 1, wherein preparing additional content for playback comprises downloading at least one content manifest associated with an alternative piece of content.

10. The method of claim 1, wherein preparing additional content for playback comprises downloading metadata associated with an alternative piece of content.

11. The method of claim 1, wherein preparing additional content for playback comprises pre-fetching cryptographic information that can be used to decrypt alternative pieces of content.

12. The method of claim 1, wherein the current piece of content is determined based upon the current content station and a current time;

and

wherein determining a plurality of alternative pieces of content using the playback device further comprises determining a plurality of alternative pieces of content based upon the current content station and the current time.

13. The method of claim 1, further comprising generating a user interface listing at least some of the plurality of content stations and at least one piece of content associated with each listed content station using the playback device;

and

wherein receiving a user instruction using the playback device comprises receiving a user instruction via the interactive user interface that identifies a listed piece of content.

14. The method of claim 1, wherein the identifiers for a plurality of pieces of content are references to content manifests, where a reference to a content manifest is associated with each piece of content.

15. The method of claim 1, wherein the station manifest further comprises a plurality of references to content manifests, where a reference to a content manifest is associated with each piece of content.

16. The method of claim 1, wherein the station manifest further comprises a plurality of jump points, where each jump point is associated with a specific location within a piece of content.

17. The method of claim 1, further comprising requesting a station manifest from a station manifest server using the playback device.

18. The method of claim 17, wherein the station manifest is generated based a user profile.

19. The method of claim 17, wherein the station manifest is generated based on the current time.

20. The method of claim 1, further comprising updating the plurality of jump points periodically.

21. The method of claim 1, wherein playing a current piece of content associated with the current content station from the plurality of pieces of content using the playback device further comprises requesting content using adaptive bitrate streaming.

22. The method of claim 1, wherein the content manifests are in at least two different formats and come from at least two different content sources.

23. The method of claim 1, wherein the user instruction is for a station change and the selected target jump point is within an alternative piece of content.

24. The method of claim 1, wherein the user instruction is for playback from a different point within the current piece of content and the selected target jump point is within the current piece of content.

25. A playback device for rapid content switching between pieces of content presented in a plurality of stations using streaming content distribution, comprising:

a processor;

a network interface; and

memory comprising a playback application;

wherein the processor is configured by the playback application to;

process at least a portion of a station manifest using a playback device, where the station manifest comprises;

identifiers for a plurality of content stations; and

identifiers for a plurality of pieces of content, where each piece of content is associated with at least one content station;

select a plurality of jump points, where each jump point is associated with a specific location within a piece of content;

determine a current content station from the plurality of content stations using the playback device;

play at least a portion of a current piece of content associated with the current content station from the plurality of pieces of content using the playback device;

determine a plurality of alternative pieces of content from the plurality of pieces of content using the station manifest using the playback device;

prepare additional content for playback at each of the plurality of jump points by preparing alternative pieces of content during playback of the current piece of content using the playback device;

receive a user instruction during playback of the current piece of content using the playback device;

select a target jump point from the plurality of jump points based upon the received user instruction using the playback device; and

commence playback of prepared additional content starting from the selected target jump point using the playback device.
