Abstract

A method for providing multimedia data from at least one controllable multimedia source to a mobile device includes providing a request path from the mobile device to a mobile service platform, receiving a request from the mobile device, obtaining a device profile from the mobile device, authenticating the identity of a user of the mobile device, and determining a user profile in response to the user identity. The method further includes authorizing control and access to the at least one multimedia source, providing a control channel from the mobile service platform to at least one multimedia server, providing multimedia data delivery information to the at least one multimedia server, and providing multimedia data to the mobile device in response to the request via the at least one multimedia server.

Claims

1. A method for providing multimedia data to a mobile device, comprising:

receiving, by a multimedia server, control commands from a mobile service platform via a control channel, the control commands for controlling delivery of multimedia data to the mobile device over a wireless path and including an authentication resulting from an authentication exchange between the mobile device and the mobile service platform;

receiving, by a transcoder, multimedia data from at least one multimedia source controlled by the mobile service platform; and

controlling, by the multimedia server, delivery of the multimedia data to the mobile device over a wireless path according to the control commands.

2. The method of claim 1, wherein the multimedia server comprises a multimedia transmitter.

3. The method of claim 1, wherein the wireless path is separate from a request path used by the mobile device in the authentication exchange.

4. The method of claim 1 wherein the transcoder is integrated with the multimedia server.

5. The method of claim 1 wherein the transcoder is a stand-alone network device coupled between at least one multimedia source and the multimedia server.

6. The method of claim 1, further comprising:

by the transcoder, adaptively encoding the multimedia data for delivery to the mobile device over the wireless path.

7. The method of claim 6, further comprising:

by the multimedia server, controlling an encoded bit rate of the multimedia data in response to performance measurement feedback.

8. The method of claim 7, further comprising:

by the multimedia server, controlling at least one of a video encoding quantization step size, a video frame rate and video frame size of the multimedia data in response to the performance measurement feedback.

9. The method of claim 7, further comprising:

by the multimedia server, controlling an encoded bit rate, frame rate and frame size of the multimedia data in response to a transmission profile, a device profile and a measured transmission parameter.

10. The method of claim 1 wherein the mobile device comprises a client decoder communicating with the multimedia server for decoding multimedia data received by the mobile device.

11. A tangible computer-readable medium having stored thereon computer readable instructions for providing multimedia data to a mobile device, wherein execution of the computer readable instructions by a processor causes the processor to perform operations comprising:

receiving, by a multimedia server, control commands from a mobile service platform via a control channel, the control commands for controlling delivery of multimedia data to the mobile device over a wireless path and including an authentication resulting from an authentication exchange between the mobile device and the mobile service platform;

receiving, by a transcoder, multimedia data from at least one multimedia source controlled by the mobile service platform; and

controlling, by a multimedia server, delivery of the multimedia data to the mobile device over a wireless path according to the control commands.

12. The tangible computer-readable medium of claim 11, wherein the multimedia server comprises a multimedia transmitter.

13. The tangible computer-readable medium of claim 11, wherein the wireless path is separate from a request path used by the mobile device in the authentication exchange.

14. The tangible computer-readable medium of claim 11, wherein the transcoder is integrated with the multimedia server.

15. The tangible computer-readable medium of claim 11, wherein the transcoder is a stand-alone network device coupled between at least one multimedia source and the multimedia server.

16. The tangible computer-readable medium of claim 11, wherein the operations further comprise:

adaptively encoding the multimedia data for delivery to the mobile device over the wireless path.

17. The tangible computer-readable medium of claim 16, wherein the operations further comprise:

controlling an encoded bit rate of the multimedia data in response to performance measurement feedback.

18. The tangible computer-readable medium of claim 17, wherein the operations further comprise:

by the multimedia server, controlling at least one of a video encoding quantization step size, a video frame rate and video frame size of the multimedia data in response to the performance measurement feedback.

19. The tangible computer-readable medium of claim 17, wherein the operations further comprise:

by the multimedia server, controlling an encoded bit rate, frame rate and frame size of the multimedia data in response to a transmission profile, a device profile and a measured transmission parameter.

20. The tangible computer-readable medium of claim 11, wherein the mobile device comprises a client decoder communicating with the multimedia server for decoding multimedia data received by the mobile device.
