Abstract

A method for controlling the streaming of voice signals in a local area network is provided. The method includes identifying at least one device to be used in the voice connection among a plurality of devices on the local area network. The method also identifies at least one mode for each of the at least one device to be used in the voice connection. The method sets the at least one mode for the at least one device and streams data over the voice connection based on the at least one mode of the at least one device.

Claims

1. A data processing system, comprising:

a plurality of devices interconnected in a local area network, each of at least three of the devices having

multiple source modes each identifying at least one other mutually different device of the plurality of devices to receive data from the each device without identifying any of the devices to provide data to the each device, and

multiple sink modes each identifying at least one other device of the plurality of devices to provide data to the each device without identifying any of the devices to receive data from the each device;

a streaming controller to select among the multiple source modes and the multiple sink modes independently of each other for any of the at least three devices, so as to establish a data streaming connection among certain of the plurality of devices as identified by the selected source and sink modes, such that, during a time period when the connection exists, at least a first of the three devices is adapted to provide data to a second of the devices in the plurality without providing data to a third device in the plurality, and is adapted to receive data from the third device without receiving data from the second device.

2. The system of claim 1 where at least one of the source modes for at least one of the at least three devices identifies multiple ones of the plurality of devices to receive streaming data from the each device.

3. The system of claim 1 where at least one of the sink modes for at least one of the at least three devices identifies multiple ones of the plurality of devices to provide data to the each device.

4. The system of claim 1 where the at least three devices include a telephone, a computer to perform a data processing function upon the streaming data, and a gateway to an external network.

5. The system of claim 4 where the computer includes a source mode (4) identifying the gateway to receive data from the telephone and a sink mode (5) identifying the telephone to provide data to the computer.

6. The system of claim 5 where the telephone includes a source mode (5) identifying the computer to receive data from the telephone and a sink mode (1) identifying the gateway to provide data to the telephone.

7. The system of claim 5 where the gateway includes a source mode identifying the telephone to receive data from the gateway and a sink mode identifying the computer to provide data to the gateway.

8. The system of claim 4 where the telephone includes a source mode identifying both the computer and the gateway to receive data from the telephone and a sink mode identifying both the computer and the gateway to provide data to the telephone.

9. The system of claim 8 where the computer includes a source mode (2) identifying the telephone only to receive data from the computer and a sink mode (5) identifying the telephone only to provide data to the telephone.

10. The system of claim 8 where the gateway includes a source mode (1) identifying the telephone only to receive data from the computer and a sink mode (3) identifying the telephone only to provide data to the telephone.

11. The system of claim 1 where the streaming controller is distributed among multiple ones of the devices.

12. The system of claim 1 where the streaming controller is implemented as a discrete unit.

13. The system of claim 1 where the controller is adapted to lock the mode of at least one of the plurality of devices.

14. The system of claim 1 where the controller includes a semaphore to prevent multiple ones of the plurality of devices from simultaneously changing modes.

15. A method, comprising:

for each of at least three devices in a plurality of devices interconnected in a local area network, defining

multiple source modes each identifying at least one other mutually different device of the plurality of devices to receive data from the each device without identifying any of the devices to provide data to the each device;

multiple sink modes each identifying at least one other device of the plurality of devices to provide data to the each device without identifying any of the devices to receive data from the each device;

selecting among the multiple source modes and the multiple sink modes independently of each other for any of the at least three devices;

establishing a data streaming connection among certain of the plurality of devices as identified by the selected source and sink modes, such that, during a time period when the connection exists, at least a first of the three devices is adapted to provide data to a second of the devices in the plurality without providing data to a third device in the plurality, and is adapted to receive data from the third device without receiving data from the second device.

16. The method of claim 15 where at least one of the source nodes for at least one of the at least three devices identifies multiple ones of the plurality of devices to receive data from the each device.

17. The method of claim 15 where at least one of the sink nodes for at least one of the at least three devices identifies multiple ones of the plurality of devices to provide data to the each device.

18. The method of claim 15 where the streaming data is voice data.

19. The method of claim 15 where at least one of the devices in the at least three devices sends and receives the streaming data to and from an external network.

20. The method of claim 15 where at least one of the devices in the at least three devices performs a processing function upon the streaming data.

21. The method of claim 20 where the processing function includes one or more of the group comprising

converting voice data to text data,

converting text data to voice data,

translating data to a different language,

recognizing voice data,

executing voice commands.

22. The method of claim 15 further comprising communicating streaming data among the certain devices.

23. The method of claim 22 further comprising locking the mode of at least one of the plurality of devices during the communication.

24. The method of claim 22 further comprising preventing multiple ones of the plurality of devices from simultaneously changing modes.

25. A computer readable medium having instructions stored thereon to perform a method comprising:

for each of at least three devices in a plurality of devices interconnected in a local area network, defining

multiple source modes each identifying at least one other mutually different device of the plurality of devices to receive data from the each device without identifying any of the devices to provide data to the each device;

multiple sink modes each identifying at least one other device of the plurality of devices to provide data to the each device without identifying any of the devices to receive data from the each device;

selecting among the multiple source modes and the multiple sink modes independently of each other for any of the at least three devices;

establishing a data streaming connection among certain of the plurality of devices as identified by the selected source and sink modes, such that, during a time period when the connection exists, at least a first of the three devices is adapted to provide data to a second of the devices in the plurality without providing data to a third device in the plurality, and is adapted to receive data from the third device without receiving data from the second device.

26. The medium of claim 25 where at least one of the source nodes for at least one of the at least three devices identifies multiple ones of the plurality of devices to receive data from the each device.

27. The medium of claim 25 where at least one of the sink nodes for at least one of the at least three devices identifies multiple ones of the plurality of devices to provide data to the each device.

28. The medium of claim 25 where at least one of the devices in the at least three devices performs a processing function upon the streaming data.
