Abstract

The present invention provides a method of controlling media streams in an electronic device that includes receiving an input stream from a plurality of applications executed on the electronic device outside of an execution thread of any of the plurality of applications and routing each of the input streams to an output device according to a set of preconfigured rules. In a second aspect, the present invention also provides an electronic device that includes a plurality of output device components and a processor that is adapted to execute 1) a plurality of applications producing streams of data, and 2) a mediator that is coupled to each of the output devices adapted to receive the data streams from each of a plurality of applications and route the data streams from the plurality of applications to one or more of the output devices according to a set of preconfigured rules.

Claims

1. A method of controlling media streams in an electronic device comprising:

receiving an input stream from each of a plurality of applications executed on the electronic device outside of an execution thread of any of the plurality of applications; and

routing each of the input streams to an output device according to a set of preconfigured rules.

2. The method of claim 1, wherein the preconfigured rules are stored in one or more tables in the electronic device.

3. The method of claim 1, wherein the routing step includes determining, for each input stream, an output device to which to route the input stream, according to the preconfigured rules.

4. The method of claim 3, further comprising:

blocking an input stream based on the presence of another of the input streams according to the preconfigured rules.

5. The method of claim 1, further comprising:

after routing, mixing an input stream with another input stream routed to the same output device.

6. The method of claim 1, wherein the input streams comprise media streams.

7. The method of claim 1, wherein the preconfigured rules differentiate between input streams based on application and content type.

8. The method of claim 7, wherein the preconfigured rules may accord a higher priority to certain applications and content types over other applications and content types.

9. The method of claim 1, wherein the receiving and routing steps are performed by a daemon that runs as a background process separately from the plurality of applications.

19. The method of claim 1, wherein the electronic device comprises a mobile device.

10. An electronic device comprising:

a plurality of output devices; and

a processor adapted to execute;

a plurality of applications, each of the plurality of applications being adapted to produce a data stream; and

a mediator coupled to each of the output devices, the mediator process being further adapted to;

receive the data streams from each of a plurality of applications and

route the data streams from the plurality of applications to one or more of the plurality of output devices according to a set of preconfigured rules.

11. The electronic device of claim 10, wherein the processor further includes one of a database or file having the set of preconfigured rules.

12. The electronic device of claim 10, wherein the mediator is further adapted to determine, for each received data stream, an output device to which to route or modify the input stream, according to the preconfigured rules.

13. The electronic device of claim 12, wherein the mediator is further adapted to modify a received data stream based on the presence of another of the received data streams according to the preconfigured rules.

14. The electronic device of claim 10, wherein the processor executes the mediator as a daemon process.

15. The electronic device of claim 10, wherein the mediator is further adapted to mix a data stream with another data stream routed to the same output device.

16. The electronic device of claim 10, wherein the data streams includes media streams.

17. The electronic device of claim 16, wherein the data streams are one of audio and graphics streams.

18. The electronic device of claim 14, wherein the plurality of applications communicate with the mediator through an interface layer executed by the processor.

20. The electronic device of claim 10, wherein the electronic device comprises a mobile device.
