Abstract

To generate a media station, a client device can receive a candidate media item playlist and media playback rules corresponding to the media station. When a new media item is needed for the media station, the client device can apply the media playback rules to a next media item in the list of candidate media items. The playback rules can be used to determine whether the next media item is currently eligible for playback. Additionally, the client device can receive a candidate invitational content item playlist and invitational content playback rules corresponding to the media station. In response to detecting an invitational content triggering action, the client device can apply the invitational content item rules to the candidate invitational content item playlist to select at least one invitational content item to present in the media stream.

Claims

1. A computer implemented method for generating on a client device a media stream corresponding to a media channel, the method comprising:

caching a first list of candidate media items, the first list comprising media item identifiers, each media item identifier representing a candidate media item and associated with metadata descriptive of the candidate media item;

caching a list of candidate invitational content, each candidate invitational content item associated with metadata descriptive of the candidate invitational content item;

selecting a first media item identifier from the first list of candidate media items and applying at least one media playback rule to generate a playback eligibility value for the first media item identifier; and

in response to detecting an occurrence of an invitational content trigger event, applying at least one invitational content rule to the list of candidate invitational content to identify at least one invitational content item.

2. The method of claim 1 further comprising:

caching a second list of candidate media items in response to detecting a change in the media channel; and

selecting a second media item identifier from the second list of candidate media items and applying at least one media playback rule to generate a playback eligibility value for the second media item identifier.

3. The method of claim 1 further comprising:

updating the list of candidate invitational content in response to detecting a number of invitational content items in the list falling below a predefined threshold value.

4. The method of claim 1, wherein each media item identifier is further associated with a reference to a media item associated with the client device.

5. The method of claim 4, wherein the reference is a reference to a media item in a media library accessible to the client device.

6. The method of claim 4, wherein the reference is a reference to a media item cached on the client device for playback in the media stream.

7. The method of claim 1, wherein an invitational content triggering event includes at least one of a media station player application launch, media item playback completion, a user interaction with the media stream, a media channel initiation, predefined movement detection, proximity detection, or a switch from a first media channel to a second media channel.

8. The method of claim 1, wherein presenting a selected invitational content item comprises preventing playback of a next media item while presenting the selected invitational content item.

10. The non-transitory computer-readable storage medium of claim 9 further comprising:

receiving the cached media playlist from a media server, the cached media playlist specific to the media channel, wherein each media item in the media playlist satisfying one or more media playlist generation rules applicable to the media channel; and

receiving the cached invitational content playlist from an invitational content server, the cached invitational content playlist corresponding to the media channel, wherein each invitational content item in the invitational content playlist satisfying one or more invitational content playlist generation rules applicable to the media channel.

11. The non-transitory computer-readable storage medium of claim 10, wherein at least one of the one or more invitational content playlist generation rules is based on user characteristics.

12. The non-transitory computer-readable storage medium of claim 9 further comprising:

updating the one or more media playback rules based on user input.

13. The non-transitory computer-readable storage medium of claim 12, wherein the user input is at least one of a like or a ban of a media item.

14. The non-transitory computer-readable storage medium of claim 9, wherein at least one of the one or more media playback rules is media channel independent.

15. A system comprising:

a processor;

a storage medium configured to store a candidate media item playlist, a candidate invitational content item playlist, one or more media playback rules, and one or more invitational content item playback rules;

a media playback rule engine configured to control the processor to apply one or more media playback rules to the candidate media item playlist to generate a currently eligible media item, and adding the currently eligible media item to a play queue;

an invitational content item playback rule engine configured to control the processor to apply one or more invitational content item playback rules to the candidate invitational content item playlist to select an invitational content item, the rule engine invoked in response to detecting an invitational content item triggering event; and

a media stream updater configured to control the processor to update a media stream by adding at least one of a next media item in the play queue or the selected invitational content item.

16. The system of claim 15, wherein an available selected invitational content item is added to the media stream prior to adding a next media item from the play queue.

17. The system of claim 15, wherein the media playback rule engine is invoked in response to detecting at least one of initiation of a new media stream or the near completion of a currently playing media item.

18. The system of claim 15 further comprising:

a storage updater module configured to control the processor to update at least one the candidate media item playlist, the candidate invitational content item playlist, one or more media playback rules, and one or more invitational content playback rules in response to detecting an initiation of a new media stream.

19. A computer implemented method comprising:

receiving a list of candidate media items corresponding to a media channel, the list of candidate media items including media item identifiers, each media item identifier in the list of candidate media items corresponding to a candidate media item, each candidate media item being locally available;

obtaining a candidate media item identifier from the list of candidate media items;

applying one or more media playback rules to the candidate media item, the one or more media playback rules determining a current eligibility for playback on the media channel; and

in response to determining the candidate media item is currently eligible for playback, adding the candidate media item to a play queue.

20. The method of claim 19 further comprising:

selecting an invitational content item from a cached list of candidate invitational content items, the selecting occurring in response to detecting an invitational content triggering event, the selecting comprising applying one or more invitational content item playback rules to the cached list of candidate invitational content items.
