Abstract

A system and method is disclosed for establishing an interactive multimedia application environment in which server-side streaming media may be controlled by a client using a programming model provided at both a communication server and an interactive multimedia runtime on the client. The application program interface (API) preferably provides methods for the client user to establish a stream of data from the client to the communication server in addition to allowing a stream from the communication server to the client. The API also preferably allows the user at a client to exert control over the broadcasting of the media streams. Streams may be built, edited, paused, stopped, augmented, and the like by the client user. Each function that the client user may operate on the broadcast media stream is preferably viewable by all of the other subscribing clients.

Claims

1. A system comprising:

a client including

a processor, and

a memory; and

the client configured to communicate with a multimedia communication server;

where communications between the client and the server are governed by an application programming interface that provides methods of control for the communications, including

a first method used by the client to selectively subscribe to media streams provided by the multimedia communication server and

a second method used by the client to publish a media stream to the multimedia communication server for provision by the multimedia communication server.

2. The system of claim 1, further comprising the multimedia communication server including a processor and a memory.

3. The system of claim 1, where the media stream published using the second method originates from one or more of:

the multimedia communication server, the client, and an external resource.

4. The system of claim 1, where the media stream published using the second method comprises a live media segment and a recorded media segment.

5. The system of claim 1, where the interface allows the client to edit media content of a given stream during broadcasting of the given stream from the multimedia communication server to multiple clients.

6. The system of claim 1, where the memory included in the multimedia communication server is configured to record the media stream published using the second method.

7. A computer-implemented method comprising:

establishing a communication connection between an accessing client and a communication server configured to broadcast a media stream over a network, where the accessing client is configured to subscribe to the media stream broadcast from the communication server;

publishing a media stream from the accessing client to the communication server for broadcasting from the communication server; and

presenting the published media stream, which is broadcast from the communication server, on a display device.

8. The method of claim 7, further comprising:

sending a script from the accessing client to the communication server to control broadcasting of the published media stream.

9. The method of claim 7, where the media stream published from the accessing client comprises a live media segment and a recorded media segment.

10. The method of claim 7, further comprising:

editing media content of a given stream during broadcasting of the given stream from the communication server to multiple clients.

11. The method of claim 7, further comprising:

editing, from the accessing client, media content of a given stream during broadcasting of the given stream from the communication server to multiple clients.

12. The method of claim 7, further comprising:

manipulating, from the accessing client, a progress of a given stream during broadcasting of the given stream from the communication server to multiple clients.

13. The method of claim 7, further comprising:

selectively recording a media stream broadcast from the communication server.

14. A non-transitory computer readable medium with computer program logic recorded thereon, the computer program logic configured to cause one or more client computers to perform operations comprising:

subscribing to a multimedia stream transmitted to multiple clients from a communication server;

publishing a media stream to the communication server for transmission from the communication server to the multiple clients;

controlling time-progress of the published media stream; and

controlling content of the published media stream.

15. The computer readable medium of claim 14, where the operations further comprise:

issuing, through a client-side application program interface, scripts that are executable by the communication server to affect transmission of one or more media streams.

16. The computer readable medium of claim 14, where the published media stream comprises a live media segment and a recorded media segment.

17. The computer readable medium of claim 14, where the operations further comprise:

editing media content of a given stream during transmission of the given stream from the communication server to multiple clients.

18. The computer readable medium of claim 14, where the operations further comprise:

selectively recording a media stream transmitted from the communication server.
