Abstract

A personal media player (PMP) uses a digital media processing system—comprising a video rendering subsystem, a music rendering subsystem, and a picture rendering subsystem—to produce moving-video (video), audio (music), still-graphics (picture), and other output rendered from media files ported to the PMP from another source. The PMP further comprises a user interface system, a display unit system, a power source system, and a data port system utilizing Universal Plug and Play functionality, all of which are coupled directly or indirectly to the digital media processing system. The physical components constituting the aforementioned systems and subsystems are then encased in a portable housing unit suitable for hand-held use and ready portability.

Claims

1. A personal media player, comprising:

a processor;

a user input device communicatively coupled with said processor;

a media output device adapted to render digital media, said media out put device communicatively coupled with said processor;

a communications port adapted to communicate over a network, the communications port communicatively coupled with said processor; and

memory communicatively coupled with the processor, the memory comprising instructions for performing the following;

requesting selected media content from a server;

validating the personal media player with the server;

receiving the selected media content and a corresponding key from the server; and

processing the received media content using data derived from the corresponding key.

2. The media player of claim 1, wherein the memory further comprises instructions for retrieving a license for the selected media content.

3. The media player of claim 2, wherein the memory further comprises instructions for determining whether to proceed with requesting the selected media content based upon the retrieved license.

4. The media player of claim 1, wherein validating the personal media player with a server comprises retrieving keys from the personal media device and forwarding the keys to a server.

5. The media player of claim 1, wherein the memory further comprises instructions for reformatting the received media content into a format suitable for rendering on the media player.

6. The media player of claim 1, wherein the memory further comprises instructions for binding the received media content to the personal media player.

7. The media player of claim 1, wherein the memory further comprises instructions for requesting a list of media content from the server.

8. A computer-readable storage medium comprising computer-executable instructions for controlling access to media content, the instructions for implementing steps comprising:

receiving a request from a personal media player for selected media content;

validating a personal media player with a server;

requesting the selected media content from the server;

receiving the selected media content and a corresponding key from the server; and

forwarding the received media content and data derived from the corresponding key to the personal media player.

9. The computer-readable storage medium of claim 8, further comprising instructions for retrieving a license for the selected media content.

10. The computer-readable storage medium of claim 9, further comprising instructions for determining whether to proceed with requesting the selected media content based upon the retrieved license.

12. The computer-readable storage medium of claim 8, further comprising instructions for reformatting the received media content into a format suitable for rendering on the media player.

13. The computer-readable storage medium of claim 8, further comprising instructions for binding the received media content to the personal media player.

14. The computer-readable storage medium of claim 8, further comprising instructions for receiving a request for a list of media content from the personal media player and transmitting a request for a list of media content to a sever.

15. The computer-readable storage medium of claim 14, further comprising instructions for communicating a list of media content to the media player.

16. A computing system adapted to control access to media content, comprising:

a server; and

computing memory communicatively coupled to said server, the computing memory having stored therein a software application adapted for the following;

validating a media player;

receiving a request for available media content;

communicating an identification of available media content;

receiving a request for selected media content; and

communicating the selected media content and a key corresponding to the selected media content,

wherein data derived from the key controls processing of the selected media content.

17. The computing system of claim 16, wherein receiving a request for available media content comprises receiving at least one request to browse available media content.
