Abstract

A system and method for Peer-to-Peer (P2P) media content streaming are provided. In one embodiment, prior to streaming desired original media content, a playback agent of a first peer playback device downloads illustration media content, which is a derivate light-weight version of the original media content. The playback agent then initiates streaming of the original media content from one or more other peer playback devices hosting the original media content or a segment thereof. The playback agent monitors a quality of the network connection to the other peer playback devices streaming the original media content to the playback agent. If the quality of the network connection falls below a defined threshold, the playback agent switches playback to the illustration media content. Once the quality of the network connection improves or a new connection is established, the playback agent switches playback back to the streaming original media content.

8. The method of claim 1 wherein the desired original media content item is a video content item, and the illustration media content item comprises a slideshow of still pictures, wherein the still pictures are frames of the desired original media content item.

9. The method of claim 8 wherein the illustration media content item further comprises an audio component accompanying the slideshow.

10. The method of claim 9 wherein the audio component of the illustration media content item is one of a group consisting of:

a narrative of the desired original media content item or an audio component of the desired original media content item.

11. The method of claim 1 wherein the illustration media content item is a low quality version of the desired original media content item.

12. The method of claim 1 wherein the illustration media content item comprises at least one advertisement.

13. The method of claim 1 wherein downloading the illustration media content item comprises one of a group consisting of:

downloading the illustration media content item from a central authority associated with the P2P network and downloading the illustration media content item from another peer playback device of the plurality of peer playback devices.

14. The method of claim 1 further comprising, after switching from the desired original media content item to the illustration media content item, switching back to the desired original media content item.

15. The method of claim 14 wherein switching back to the desired original media content item comprises switching back to the desired original media content item when the quality of the network connection increases to a second defined level that is greater than or equal to the defined level.

16. The method of claim 14 wherein switching back to the desired original media content item comprises:

initiating streaming of the desired original media content item from at least one of the plurality of peer playback devices via a new connection; and

switching playback from the illustration media content item to the desired original media content item.

25. The method of claim 1 further comprising, after switching from the desired original media content item to the illustration media content item, switching back to the desired original media content item.

17. A peer playback device in a Peer-to-Peer (P2P) network formed by a plurality of peer playback devices including the peer playback device, comprising:

a communication interface of the peer playback device communicatively coupling the peer playback device to the P2P network; and
