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 system for providing multimedia data to a mobile device, the system comprising:

a mobile service platform comprising;

an authentication processor for authenticating user requests from the mobile device over a request path; and

a multimedia source controller for receiving the authenticated user requests for controlling at least one multimedia source;

at least one multimedia server for receiving control commands via a control channel from the mobile service platform, the control commands being for controlling delivery of multimedia data to the mobile device over a wireless path separate from the request path; and

at least one transcoder for receiving multimedia data from the at least one multimedia source and coupled to the at least one multimedia server.

2. The system of claim 1 wherein the at least one transcoder is integrated with a corresponding at least one multimedia server.

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

4. The system of claim 1 wherein the mobile service platform further comprises a personalization information management processor for providing personalized data associated with a user of the mobile device.

5. The system of claim 1 wherein the at least one transcoder comprises an adaptive encoder for encoding multimedia data for delivery to the mobile device over a wireless path.

6. The system of claim 1 wherein the at least one multimedia server comprises a multimedia transmitter.

7. The system of claim 6 wherein the mobile device communicates with the multimedia transmitter using at least one of:

a CDPD protocol;

a TDMA protocol;

a GSM protocol;

an 802.11 protocol;

a two way paging protocol;

a CDMA protocol;

a GPRS protocol;

a CDMA-2000 protocol; and

a W-CDMA protocol.

8. The system of claim 1 wherein the authentication processor accesses a plurality of user profile data structures.

9. The system of claim 1 wherein the mobile service platform further comprises a personalization information management processor for providing personalized data associated with a user of the mobile device, and wherein the personal information management processor accesses a plurality of user profile data structures.

10. The system of claim 1 wherein the at least one multimedia server accesses a device profile.

11. The system of claim 1 wherein the at least one multimedia server accesses a transmission profile.

12. The system of claim 1 wherein the multimedia server further comprises a feedback control processor coupled to the adaptive encoder, the feedback control processor being for controlling an encoded bit rate of the multimedia data in response to performance measurement feedback.

13. The system of claim 12 wherein feedback control processor is further for controlling at least one of a video encoding quantization step size, a video frame rate and video frame size of the multimedia data.

14. The system of claim 12 wherein feedback control processor is further for 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.

15. The system of claim 1 wherein the mobile device comprises a client decoder communicating with the at least one multimedia server for decoding multimedia data received by the mobile device.

16. A multimedia delivery system comprising;

a mobile service platform having a control path output;

a multimedia server for serving multimedia content to a client on a path separate from the mobile service platform, the server having a session manager, an encoder, a feedback control and a control path input coupled to the control path output for directing the multimedia server to serve the multimedia content; and

a client decoder having a performance measurement processor.

17. The system of claim 16 wherein the multimedia server further comprises a decoder coupled to a plurality of multimedia sources.

18. The system of claim 16 wherein the multimedia server further comprises a network state information data structure coupled to the feedback control and decision processor.

19. A wireless network, comprising:

a mobile service platform having an authentication processor for authenticating user requests from the mobile device and a multimedia source controller for receiving the authenticated user requests for controlling at least one multimedia source;

a multimedia server for receiving control commands from the mobile service platform and coupled to an adaptive transcoder for wireless data delivery; and

a client decoder coupled to the mobile service platform via a user request path and coupled to the multimedia server via a wireless data delivery path separate from the user request path.
