Abstract

A system and method for managing multiple live video broadcasts via a public data network on a single viewing channel is disclosed. An example embodiment includes receiving requests from a plurality of broadcasters wishing to broadcast at the same time on a channel of a public data network; queuing and prioritizing the requests in a broadcast queue; broadcasting content corresponding to a request of a first broadcaster on the channel; notifying a second broadcaster corresponding to one of a plurality of pending requests in the broadcast queue that the second broadcaster'"'"'s opportunity for broadcast on the channel is imminent; discontinuing the broadcast of the content of the first broadcaster based on multiple factors; broadcasting content corresponding to a request of the second broadcaster on the channel; and using a coordinated real-time rendezvous to enable an audience of the channel to automatically transition from receiving the broadcast of the content of the first broadcaster to receiving the broadcast of the content of the second broadcaster on the same channel over the public data network.

Claims

1. A method comprising:

receiving requests from a plurality of broadcasters requesting to broadcast on a shared channel of a public data network, the broadcasters representing continuous streaming media feeds of either live or pre-rendered content;

queuing and prioritizing the broadcaster-originated requests in a broadcast queue that controls a singular viewing order of content to a multitude of simultaneous viewers representing an audience to enable each of the plurality of broadcasters to broadcast on the shared channel at a different time slot based on dynamic queue positioning performed in real-time, the dynamic queue positioning including first-come, first-served positioning, and front of the queue positioning based on specific priority factors, including broadcaster privilege or specified broadcast timing;

broadcasting content corresponding to a request of a first broadcaster on the shared channel;

discontinuing the broadcast of the content of the first broadcaster based on multiple factors;

broadcasting content corresponding to a request of the second broadcaster on the shared channel; and

using a coordinated real-time rendezvous to enable the audience of the shared channel to automatically transition from receiving the broadcast of the content of the first broadcaster to receiving the broadcast of the content of the second broadcaster on the shared channel over the public data network.

2. The method as claimed in claim 1 including:

gathering near real-time audience feedback as related to the content broadcast by the first broadcaster.

3. The method as claimed in claim 2 wherein the near real-time audience feedback is included as at least one factor in the multiple factors used to discontinue the broadcast of the content of the first broadcaster.

4. The method as claimed in claim 1 including:

providing the plurality of broadcasters with information related to broadcast time slot availability on the shared channel.

5. The method as claimed in claim 1 including:

allowing a request from one of the plurality of broadcasters to enter the broadcast queue as a pending request.

6. The method as claimed in claim 1 including:

changing status information corresponding to the first broadcaster to an inactive status when the broadcast of the content of the first broadcaster is discontinued.

7. The method as claimed in claim 1 including:

changing status information corresponding to the second broadcaster to an active status when the broadcast of the content of the second broadcaster is initiated.

8. The method as claimed in claim 1 wherein the public data network is the Internet.

9. The method as claimed in claim 1 wherein the coordinated real-time rendezvous uses audience mediation.

10. The method as claimed in claim 1 wherein the coordinated real-time rendezvous uses publisher mediation.

21. The method of claim 1 including notifying a second broadcaster corresponding to a next one of a plurality of pending requests in the broadcast queue that the second broadcaster'"'"'s opportunity for broadcast on the shared channel is imminent.

11. A system comprising:

a processor;

a database, in data communication with the processor, for storage of broadcast related information;

a media server, in data communication with the processor, for broadcasting content; and

a server-side monitor, executable by the processor, to receive requests from a plurality of broadcasters requesting to broadcast on a shared channel of a public data network, the broadcasters representing continuous streaming media feeds of either live or pre-rendered content;

to queue and prioritize the broadcaster-originated requests in a broadcast queue that controls a singular viewing order of content to a multitude of simultaneous viewers representing an audience to enable each of the plurality of broadcasters to broadcast on the shared channel at a different time slot based on dynamic queue positioning performed in real-time, the dynamic queue positioning including first-come, first-served positioning, and front of the queue positioning based on specific priority factors, including broadcaster privilege or specified broadcast timing;

to direct the media server to broadcast content corresponding to a request of a first broadcaster on the shared channel;

to direct the media server to discontinue the broadcast of the content of the first broadcaster based on multiple factors;

to direct the media server to broadcast content corresponding to a request of the second broadcaster on the shared channel; and

to use a coordinated real-time rendezvous to enable the audience of the shared channel to automatically transition from receiving the broadcast of the content of the first broadcaster to receiving the broadcast of the content of the second broadcaster on the shared channel over the public data network.

12. The system as claimed in claim 11 wherein the server-side monitor being further configured to gather near real-time audience feedback as related to the content broadcast by the first broadcaster.

13. The system as claimed in claim 12 wherein the near real-time audience feedback is included as at least one factor in the multiple factors used to discontinue the broadcast of the content of the first broadcaster.

14. The system as claimed in claim 11 wherein the server-side monitor being further configured to provide the plurality of broadcasters with information related to broadcast time slot availability on the shared channel.

15. The system as claimed in claim 11 wherein the public data network is the Internet.

16. The system as claimed in claim 11 wherein the coordinated real-time rendezvous uses audience mediation.

17. The system as claimed in claim 11 wherein the coordinated real-time rendezvous uses publisher mediation.

22. The system of claim 11 wherein the server-side monitor being further configured to notify a second broadcaster corresponding to a next one of a plurality of pending requests in the broadcast queue that the second broadcaster'"'"'s opportunity for broadcast on the shared channel is imminent.

18. A non-transitory machine-useable storage medium embodying instructions which, when executed by a machine, cause the machine to:

receive requests from a plurality of broadcasters requesting to broadcast on a shared channel of a public data network, the broadcasters representing continuous streaming media feeds of either live or pre-rendered content;

queue and prioritize the broadcaster-originated requests in a broadcast queue that controls a singular viewing order of content to a multitude of simultaneous viewers representing an audience to enable each of the plurality of broadcasters to broadcast on the shared channel at a different time slot based on dynamic queue positioning performed in real-time, the dynamic queue positioning including first-come, first-served, positioning, and front of the queue positioning based on specific priority factors, including broadcaster privilege or specified broadcast timing;

direct a media server to broadcast content corresponding to a request of a first broadcaster On the shared channel;

direct the media server to discontinue the broadcast of the content of the first broadcaster based on multiple factors;

direct the media server to broadcast content corresponding to a request of the second broadcaster on the shared channel; and

use a coordinated real-time rendezvous to enable the audience of the shared channel to automatically transition from receiving the broadcast of the content of the first broadcaster to receiving the broadcast of the content of the second broadcaster on the shared channel over the public data network.

19. The machine-useable storage medium as claimed in claim 18 wherein the instructions being further configured to gather near real-time audience feedback as related to the content broadcast by the first broadcaster.

20. The machine-useable storage medium as claimed in claim 19 wherein the near real-time audience feedback is included as at least one factor in the multiple factors used to discontinue the broadcast of the content of the first broadcaster.

23. The machine-useable storage medium of claim 18 being further configured to notify a second broadcaster corresponding to a next one of a plurality of pending requests in the broadcast queue that the second broadcaster'"'"'s opportunity for broadcast on the shared channel is imminent.
