Abstract

Method and system for broadcasting live data over a network are described. In one embodiment, live data is accessed. Next, a first client is authenticated. The live data is then broadcast to a first client, wherein the first client is capable of buffering and re-transmitting the live data. Next, a second client is authenticated. A list of clients receiving the live data is then sent to the second client. The second client then selects the first client from the list, contacts the first client, and then receives the live data from the first client.

Claims

1. A server implemented method for terminating broadcasting of live data, said method comprising:

broadcasting live data to a first client, wherein said first client is operable to retransmit said live data to a second client;

receiving a termination request signal from said first client; and

enabling said second client to receive said live data from a third client before departure of said first client.

2. The method as described in claim 1, wherein said enabling comprises:

directing said third client to retransmit said live data to said second client.

3. The method as described in claim 1, wherein said enabling comprises:

sending a list of clients to said second client, wherein said list comprises clients that are receiving said live data, and wherein said list comprises clients that are capable of retransmission of said live data, and wherein said second client in response to selecting said third client receives said live data from said third client.

4. The method as described in claim 3, wherein said server directs said third client to retransmit said live data to said second client.

5. The method as described in claim 3, wherein said list of clients comprises broadcast properties comprising:

an IP address of said third client;

a speed of connection of said third client;

a number of clients already receiving said live data from said third client; and

a history of said third client up-time.

6. The method as described in claim 1 further comprising:

in response to said enabling, terminating said broadcasting said live data to said first client.

7. The method as described in claim 1, wherein said third client is accessing said live data at an upper level of a broadcasting chain in comparison to said second client.

8. The method as described in claim 1 further comprising:

maintaining said retransmission of said live data from said first client to said client until said second client receives said live data from said third client.

9. The method as described in claim 1, wherein said first client receives said live data directly from said server.

10. A system comprising a processor, a transmitter/receiver and a memory component operable to store instructions that when executed on said processor implement a method for terminating broadcasting of live data, said method comprising:

broadcasting live data to a first client, wherein said first client is operable to retransmit said live data to a second client;

receiving a termination request signal from said first client; and

enabling said second client to receive said live data from a third client before departure of said first client.

11. The system as described in claim 10, wherein said enabling comprises:

directing said third client to retransmit said live data to said second client.

12. The system as described in claim 10, wherein said enabling comprises:

sending a list of clients to said second client, wherein said list comprises client that are receiving said live data, and wherein said list comprise clients that are capable of retransmission of said live data, and wherein said second client in response to selecting said third client receives said live data from said third client.

13. The system as described in claim 12, wherein said server directs said third client to retransmit said live data to said second client.

14. The system as described in claim 12, wherein said list of clients comprises broadcast properties comprising:

an IP address of said third client;

a speed of connection of said third client;

a number of clients already receiving said live data from said third client; and

a history of said third client up-time.

15. The system as described in claim 10 wherein said method further comprises:

in response to said enabling, terminating said broadcasting said live data to said first client.

16. The system as described in claim 10, wherein said third client is accessing said live data at an upper level of a broadcasting chain in comparison to said second client.

17. The system as described in claim 10 wherein said method further comprises:

maintaining said retransmission of said live data from said first client to said client until said second client receives said live data from said third client.

18. The system as described in claim 10, wherein said first client receives said live data directly from said server.
