Abstract

A method of synchronizing playback of a media asset between a first playback device and one or more other playback devices includes synchronizing an initial playback timeline of a media asset with a reference clock, and then playing the media asset with the initial playback timeline on each of the two or more playback devices. In response to a playback-alteration command, an updated playback timeline of the media asset is synchronized with the reference clock, and the media asset is then played with the updated playback timeline on each of the two or more playback devices.

Claims

1. A method of providing a social media experience via two or more playback devices, the method comprising:

synchronizing an initial playback timeline of a media asset with a reference clock, the initial playback timeline having an initial playback speed;

starting playback of the media asset from a same start point with the initial playback speed of the initial playback timeline on each of the two or more playback devices;

in response to a fast forward, rewind, or slow motion playback-alteration command, synchronizing an updated playback timeline of the media asset with the reference clock, the updated playback timeline having an updated playback speed that is different than the initial playback speed; and

playing the media asset with the updated playback speed of the updated playback timeline on each of the two or more playback devices so as to provide a synchronized fast forward, rewind, or slow motion between each of the two or more playback devices.

2. The method of claim 1, where the playback-alteration command is communicated from one playback device to all other participating playback devices as a playback-alteration message.

3. A method of synchronizing playback of an audio/video media asset between a first playback device and one or more other playback devices, including a second playback device, the method comprising:

synchronizing a first reference clock accessible by the first playback device with a second reference clock accessible by the second playback device;

acknowledging the audio/video media asset that is to be synchronized on the first playback device and the second playback device;

acknowledging a start point along a progress timeline of the audio/video media asset at which playback is to begin on the first playback device and the second playback device;

acknowledging a reference time when playback is to begin on the first playback device;

creating a first playback timeline for the first playback device by temporally aligning the progress timeline to the first reference clock so that the start point syncs with the reference time, the first playback timeline matching a second playback timeline for the second playback device;

playing the audio/video media asset with a first video resolution from the start point with the first playback timeline on the first playback device while the audio/video media asset is played with a second video resolution, different than the first video resolution, from the start point with the second playback timeline on the second playback device;

while playing the audio/video media asset on the first playback device, sending participant audio communications from the first playback device to the second playback device and/or receiving participant audio communications at the first playback device from the second playback device, the participant audio communications including an audio chat.

4. The method of claim 3, further comprising acknowledging a playback rate at which playback is to occur, where the first playback timeline is set according to a playback rate.

5. The method of claim 3, where synchronizing the first reference clock with the second reference clock includes synchronizing a device clock of the first playback device to a network time server.

6. The method of claim 3, where the audio/video media asset is an audio-visual asset having a definite visual scene structure and one or more audio tracks.

7. The method of claim 3, where the audio/video media asset has two or more different instances with different content, and where a first instance of the audio/video media asset is played on the first playback device while a second instance of the audio/video media asset is played on the second playback device.

8. The method of claim 7, where the first instance of the audio/video media asset is a local copy of the audio/video media asset saved on the first playback device and the second instance of the audio/video media asset is a local copy of the audio/video media asset saved on the second playback device.

9. The method of claim 7, where the first instance of the audio/video media asset is a remote copy of the audio/video media asset served to the first playback device and the second instance of the audio/video media asset is a remote copy of the audio/video media asset served to the second playback device.

10. The method of claim 7, where the first instance of the audio/video media asset is a remote copy of the audio/video media asset served to the first playback device and the second instance of the audio/video media asset is a local copy of the audio/video media asset saved on the second playback device.

11. The method of claim 3, where a first instance of the audio/video media asset is played with a first audio track on the first playback device while a second instance of the audio/video media asset is played with a second audio track on the second playback device, the second audio track being different than the first audio track.

12. The method of claim 3, where a first instance of the audio/video media asset is played with a first video quality on the first playback device while a second instance of the audio/video media asset is played with a second video quality on the second playback device, the second video quality being different than the first video quality.

13. The method of claim 3, where playback of a first instance of the audio/video media asset on the first playback device is contingent on a first digital rights management check and playback of a second instance of the audio/video media asset on the second playback device is contingent on a second digital rights management check, different than the first digital rights management check.

14. The method of claim 3, where acknowledging the start point and acknowledging the reference time includes receiving at the first playback device a playback-alteration message indicating the start point and the reference time, the playback-alteration message originating from the second playback device.

15. The method of claim 14, where the playback-alteration message is received via a synchronization server.

16. The method of claim 3, where acknowledging the start point and acknowledging the reference time includes sending to the second playback device a playback-alteration message indicating the start point and the reference time, the playback-alteration message originating from the first playback device.

17. The method of claim 16, where the playback-alteration message is sent via a synchronization server.

18. The method of claim 3, where the reference time includes a delay from a present time to accommodate network and/or pipeline latency on one or more playback devices.

19. The method of claim 3, where the participant communications include audio-visual chat communications.

20. The method of claim 3, where synchronization between the first playback device and the second playback device is maintained via a playback-alteration message sent as a peer-to-peer communication.
