Abstract

A method and system for performing chaincast communication to multiple communication systems within a system of coupled electronic devices. In one implementation the electronic devices can be computer systems and the system of coupled electronic devices includes the Internet. The present invention provides a system wherein a broadcast source communicates broadcast information (e.g., encoded audio radio content, encoded audio/video television content, program instructions, etc.) to a first group of electronic devices. The first group of electronic devices can be instructed by a transmission scheduler to then communicate (e.g., forward) the broadcast information to other electronic devices which devices can also be instructed to communicate to more devices, etc., thereby reducing the bandwidth requirements of the communication channel between the broadcast source and the first group of electronic devices.

Claims

1. A method of communicating broadcast information, said method comprising:

receiving at a first user device a list comprising a plurality of different content selections;

sending from said first user device a content selection whose delivery is requested at a present time to a transmission scheduler;

after said content selection is sent from said first user device and in response to instructions from said transmission scheduler, creating a first communication link between said first user device and a second user device that is receiving and rendering to a second user broadcast information representing said content selection, wherein said first user device is downstream from said second user device; and

receiving at said first user device said broadcast information from said second user device via said first communication link to render to a first user.

2. The method of claim 1, wherein said broadcast information is a radio program.

3. The method of claim 1, wherein said broadcast information is a television program.

4. The method of claim 1, wherein said broadcast information is a computer program.

5. The method of claim 1, further comprising:

receiving at a third user device said list comprising said plurality of different content selections;

sending from said third user device a second content selection whose delivery is requested at a present time to said transmission scheduler;

while receiving said broadcast information at said first user device and in response to instructions from said transmission scheduler, creating a second communication link between said third user device and said first user device which is receiving said broadcast information representing said second content selection, wherein said third user device is downstream from said first user device; and

retransmitting from said first user device said broadcast information to said third user device to render to a third user via said second communication link.

6. The method of claim 5 further comprising:

transmitting said broadcast information to said second user device from a server;

in response to said second user device shutting down and in response to instructions from said transmission scheduler, creating a third communication link between said first user device and said server; and

receiving at said first user device said broadcast information from said server via said third communication link.

7. The method of claim 1 further comprising:

sending status update messages to said transmission scheduler.

8. A method of broadcasting information over a network of electronic devices, said method comprising:

receiving at a first electronic device a list comprising a plurality of different content selections;

sending from said first electronic device a content selection whose delivery is requested at a present time to a transmission scheduler;

after said content selection is sent from said first electronic device and in response to instructions from said transmission scheduler, creating a first communication link between said first electronic device and a second electronic device of a group of electronic devices that are receiving and rendering broadcast information representing said content selection, wherein said first electronic device is downstream from said second electronic device; and

receiving at said first electronic device said broadcast information to render from said second electronic device via said first communication link.

9. The method of claim 8 further comprising periodically sending status update messages from said electronic devices to said transmission scheduler.

10. The method of claim 8, wherein said broadcast information is a radio program.

11. The method of claim 8, wherein said broadcast information is a television program.

12. The method of claim 8, wherein said broadcast information is a computer program.

13. The method of claim 8, wherein said network of electronic devices comprises the Internet.

14. The method of claim 8 further comprising:

receiving at a third electronic device said list comprising said plurality of different content selections;

sending from said third electronic device a second content selection whose delivery is requested at a present time to said transmission scheduler;

while receiving said broadcast information at said first electronic device and in response to instructions from said transmission scheduler, creating a second communication link between said third electronic device and said first electronic device which is receiving said broadcast information representing said second content selection, wherein said third electronic device is downstream from said first electronic device; and

retransmitting from said first electronic device said broadcast information to said third electronic device to render via said second communication link.

15. The method of claim 14 further comprising:

in response to said second electronic device shutting down and in response to instructions from said transmission scheduler, creating a third communication link between said first electronic device and a fourth electronic device of said group, wherein said first electronic device is downstream from said fourth electronic device; and

receiving at said first electronic device said broadcast information from said fourth electronic device via said third communication link.

16. A user device, comprising:

a memory; and

a processor operable to receive a list comprising a plurality of different content selections, wherein said processor is operable to send a content selection whose delivery is requested at a present time to a transmission scheduler, wherein after said content selection is sent and in response to instructions from said transmission scheduler, said processor is operable to create a first communication link between said user device and a second user device that is receiving and rendering to a second user broadcast information representing said content selection, wherein said user device is downstream from said second user device, and wherein said processor is operable to receive said broadcast information from said second user device via said first communication link to render to a first user.

17. The user device of claim 16, wherein said broadcast information is a radio program.

18. The user device of claim 16, wherein said broadcast information is a television program.

19. The user device of claim 16, wherein said broadcast information is a computer program.

20. The user device of claim 16, wherein said processor is operable to send status update messages to said transmission scheduler
