Abstract

A device accepts a set of configuration parameters relating to components involved in data streaming (e.g., clients or network equipment) and transforms a data stream in response to such configuration parameters, transmitting the transformed data stream onward to a client. Dynamic changes in the configuration parameters may affect the transformations.

Claims

1. A method comprising:

accepting a set of configuration parameters;

accepting a data stream from a server;

transforming the data stream in response to the configuration parameters;

and transmitting the transformed data stream to a data stream client.

2. The method of claim 1 wherein the configuration parameters reflect the capabilities of a network that transmits information between the server and the data stream client.

3. The method of claim 2 wherein the capabilities of the network include bandwidth information for the network.

4. The method of claim 2 wherein the capabilities of the network include load information for the network.

5. The method of claim 1 wherein the configuration parameters reflect the capabilities of the data stream client.

6. The method of claim 1 wherein the capabilities of the data stream client reflect the amount of data the data stream client may accept in a data stream.

7. The method of claim 1 wherein the capabilities of the data stream client reflect the compression capabilities of the client.

8. The method of claim 1 wherein the capabilities of the data stream client reflect the number of data streams the client may accept.

9. The method of claim 1 comprising:

accepting the data request of a second client; and

modifying the manner in which the data stream is transformed when sent to the data stream client.

10. The method of claim 1 wherein the data stream is audio streaming data.

11. The method of claim 1 wherein the data stream is video streaming data.

12. The method of claim 1, wherein the transformation is transcoding.

13. The method of claim 1, wherein the configuration parameters include information on data stream requests.

14. A method comprising:

accepting a set of configuration parameters;

accepting a data stream from a server;

transcoding the data stream in response to the configuration parameters; and

transmitting the transcoded data stream to a data stream client.

15. A method comprising:

accepting a set of configuration parameters including information on client capabilities and network component capabilities;

accepting a data stream from a server;

transforming the data stream in based on the configuration parameters; and

transmitting the transformed data stream to a data stream client.

16. A device for converting streaming data sent by a server to a set of clients, the device comprising:

a data converter; and

a configuration memory holding data on the capabilities of a subset of the clients;

wherein the data converter converts the data stream into an output data stream for transmission to a client based on the capabilities of a client.

17. The device of claim 16, wherein the data converter includes at least a digital signal processor.

18. The device of claim 16, wherein the device accepts configuration changes and, in response to such changes, alters the data conversion.

19. A device for converting streaming data sent by a server to a set of clients, the device comprising:

a data converter; and

a configuration memory holding data on the capabilities of a set of networks;

wherein the data converter converts the data stream into an output data stream for transmission to a client based on the capabilities of the networks.

20. The device of claim 19, wherein the data converter includes at least a digital signal processor.

21. The device of claim 19, wherein the data converter converts the data stream into an output data stream for transmission to a client based on the capabilities of a client.

22. The device of claim 19, wherein the device accepts configuration changes and, in response to such changes, alters the data conversion.

23. The device of claim 22, wherein the configuration changes include information on client capabilities.

24. The device of claim 22, wherein the configuration changes include information on network capabilities.

25. The device of claim 20, wherein the configuration changes include information on data stream requests.
