Abstract

Portable media devices allow a user to access music or other media stored on the device, and two portable media devices equipped with wireless technology can exchange stored files over the air.

Claims

1. A method comprising:

creating a content library that is accessible to a wireless portable media (WPM) server;

establishing a wireless link between the WPM server and one or more WPM clients;

receiving at the WPM server a request for content, wherein the request is associated with the one or more WPM clients;

searching the content library for content that matches the request;

sending the content via the wireless link to the one or more WPM clients.

2. The method of claim 1, further comprising receiving additional commands selected from the group consisting of rewind, fast forward, replay, pause, stop, wherein the additional commands effect the sending of the content in accordance with the command.

3. The method of claim 1, wherein the wireless link follows a standard selected from the group consisting of 802.11a, 802.11b, 802.11g, 802.11n, 802.15.

4. The method of claim 1, further comprising using multiple antennae to optimize system performance based on wireless channel conditions and the number of users accessing the WPM server through a technique selected from the group consisting of diversity combining, beamforming, spatial multiplexing, a combination thereof.

5. The method of claim 1, further comprising streaming the content via the wireless link using end-to-end quality optimization by exploiting flexibility in the wireless link and MAC layers.

6. The method of claim 1, further comprising streaming the content via the wireless link using end-to-end quality optimization using quality of service (QoS) capabilities associated with a standard associated with the wireless link.

7. The method of claim 1, wherein the wireless link is in accordance with one of the IEEE 802.11 standards, further comprising using quality of service (QoS) capabilities of IEEE.11e standards.

8. The method of claim 1, further comprising:

receiving a request to share content among the one or more WPM clients;

broadcasting content associated with the request to the one or more WPM clients simultaneously over independent channels.

9. The method of claim 1, wherein the content is stored in the content library in one or more independent libraries associated with the one or more WPM clients.

10. The method of claim 1, wherein the content is stored in the content library in a shared library.

11. The method of claim 1, further comprising storing multiple file sizes for a content file, wherein searching the content library includes:

considering conditions associated with a WPM client of the one or more WPM clients;

selecting a file size that is appropriate for transmission to the WPM client based upon the consideration of conditions.

12. The method of claim 1, further comprising coupling the WPM server to an automobile.

13. A system comprising:

a plurality of wireless devices;

a wireless content server, including;

an interface coupled to the plurality of wireless devices;

a content server engine embodied in a computer-readable medium, coupled to the interface;

a database interface coupled to the content provisioning engine and the content server engine;

a content database coupled to the database interface,

wherein, in operation, requests for content from a wireless device of the plurality of wireless devices is received at the interface, the content server engine determines whether content uniquely identified in association with the request is stored in the content database, and the uniquely identified content is provided from the content database through the database interface and the content server engine to the interface for sending to the plurality of wireless devices.

14. The system of claim 13, further comprising:

a content provider coupled to the interface of the wireless content server;

a content provisioning engine embodied in a computer-readable medium, coupled to the interface;

wherein, in operation, content from the content provider is received at the interface, the content provisioning engine determines whether to store the content in the content database, and, if the content is to be stored, the content is provided to the database interface for storage in the content database.

15. The system of claim 13, wherein the content database includes flash memory.

16. The system of claim 13, wherein the wireless content server includes multiple antennae.

17. The system of claim 13, wherein a wireless device of the plurality of wireless devices includes a headset.

18. The system of claim 13, wherein a wireless device of the plurality of wireless devices includes a portable speaker system.

19. The system of claim 13, wherein a wireless device of the plurality of wireless devices includes a handset.

20. A system comprising:

a wireless portable media (WPM) server;

one or more WPM clients wirelessly coupled to the WPM server;

a means for receiving at the WPM server content from a content provider;

a means for wirelessly providing the content from the WPM server to the one or more WPM clients.
