Abstract

Systems and methods are provided for audio device playback failure recovery and redistribution. The systems and methods may be configured to cause a plurality of playback devices to render audio content in a synchronized manner, detect a failure of a first playback device of the plurality of playback devices, determine a playback responsibility of the first playback device, and cause an adjustment of the rendering of the audio content by at least a second playback device of the plurality of playback devices. The systems and methods may further be configured to detect an addition of a new playback device to the plurality of playback devices, determine a playback responsibility of the new playback device for rendering the audio content, and cause an adjustment of the rendering of the audio content by at least a one playback device from the plurality of playback devices.

Claims

1. A method for automatic failover recovery comprising:

causing a plurality of playback devices to render audio content in a synchronized manner;

detecting a failure of a first playback device of the plurality of playback devices;

determining a playback responsibility of the first playback device; and

causing an adjustment of the rendering of the audio content by at least a second playback device of the plurality of playback devices, the adjustment based on the playback responsibility of the first playback device.

2. The method of claim 1, wherein the audio content comprises multiple audio channels and multiple audio frequency ranges, and wherein the playback responsibility of the first playback device indicates a playback volume, one or more audio channels, and one or more audio frequency ranges of the audio content rendered by the first playback device.

3. The method of claim 2, wherein causing an adjustment of the rendering of the audio content by at least a second playback device comprises adding the playback responsibility of the first playback device to the rendering of the audio content by the at least second playback device.

4. The method of claim 2, wherein the failure of a first playback device involves an inability of the first play playback device to render at least one of the playback volume, the one or more audio channels, or one of the one or more audio frequency ranges indicated by the playback responsibility of the first playback device.

5. The method of claim 1, wherein detecting a failure of a first playback device from the plurality of playback devices comprises receiving device status information from each of the plurality of playback devices at a periodic interval.

6. The method of claim 5, wherein detecting a failure of a first playback device from the plurality of playback devices further comprises determining that device status information from the first playback device has not been received for a number of periodic intervals.

7. The method of claim 5, wherein detecting a failure of the first playback device from the plurality of playback devices further comprises receiving device status information from the first playback device indicating a failure of the first playback device.

8. The method of claim 1, further comprising:

receiving device information associated with each playback device of the plurality of playback devices; and

selecting at least the second playback device from the plurality of playback devices based on the device information associated each playback device.

9. The method of claim 8, wherein selecting at least the second playback device from the plurality of playback devices based on the device information associated with each playback device comprises determining that at least the second playback device is capable of rendering the playback responsibility of the first playback device.

10. A method for automatic failover recovery comprising:

causing a plurality of playback devices to render audio content in a synchronized manner;

detecting an addition of a new playback device to the plurality of playback devices;

determining a playback responsibility of the new playback device for rendering the audio content; and

causing an adjustment of the rendering of the audio content by at least a one playback device from the plurality of playback devices, the adjustment based on the playback responsibility of the first playback device.

11. The method of claim 10, wherein the new playback device was previously a failed playback device in the plurality of playback devices.

12. The method of claim 10, wherein detecting an addition of a new playback device to the plurality of playback devices comprises receiving device status information from the new playback device at a periodic interval.

13. The method of claim 10, further comprising receiving device capability information indicating playback capabilities of the new playback device, wherein determining the playback responsibility of the new playback device for rendering the audio content is based on the playback capabilities of the new playback device.

14. The method of claim 10, wherein the audio content comprises multiple audio channels and multiple audio frequency ranges, and wherein the playback responsibility of the new playback device indicates a playback volume, one or more audio channels, and one or more audio frequency ranges of the audio content to be rendered by the new playback device.

15. The method of claim 14, wherein causing an adjustment of the rendering of the audio content by at least a one playback device comprises removing the playback responsibility of the new playback device from the rendering of the audio content by the at least one playback device.

16. A system comprising:

a plurality of audio playback devices configured to render audio content; and

a processing unit in communication with the plurality of audio playback device, the processing unit configured to;

cause the plurality of playback device to render the audio content in a synchronized manner;

detect a failure of a first playback device of the plurality of playback devices;

determine a playback responsibility of the first playback device; and

cause an adjustment of the rendering of the audio content by at least a second playback device from the plurality of playback devices, the adjustment based on the playback responsibility of the first playback device.

17. The system of claim 16, wherein the adjustment of the rendering of the audio content by at least a second playback device comprises an addition of the playback responsibility of the first playback device to the rendering of the audio content by the at least second playback device.

18. The system of claim 16, wherein the processing unit is further configured to:

detect an addition of a new playback device to the plurality of playback devices;

determine a playback responsibility of the new playback device for rendering the audio content;

cause an adjustment of the rendering of the audio content by at least a third playback device from the plurality of playback devices, the adjustment based on the playback responsibility of the new playback device.

19. The system of claim 18, wherein the new playback device is the first playback device, and wherein the processing unit is further configured determine the playback responsibility of the new playback device for rendering the audio content based on the playback responsibility of the first playback device.

20. The method of claim 18, wherein the adjustment of the rendering of the audio content by at least the third playback device comprises a removal of the playback responsibility of the new playback device from the rendering of the audio content by at least the third playback device.
