Abstract

Methods and apparatus are disclosed for implementing a mobile digital radio playlist system. The playlist need not be maintained in a vehicle; preferably it is maintained on a user'"'"'s equipment such as a computer, PDA, MP3 player or the like. The system enables a method of updating such a playlist conveniently, for example while traveling in a vehicle, by capturing indicia of a current song in a mobile digital radio receiver in response to a user capture input; transmitting the captured indicia from the digital radio receiver to a wireless telecommunication device; in the wireless telecommunication device, forwarding the captured indicia to a playlist server; and in the playlist server, forwarding the received indicia to the user'"'"'s equipment to update the playlist.

Claims

1. A method of updating a playlist stored on user equipment, the method comprising the steps of:

(a) capturing indicia of a current song in a mobile digital radio receiver in response to a user capture input;

(b) transmitting the captured indicia from the digital radio receiver to a wireless telecommunication device;

(c) in the wireless telecommunication device, forwarding the captured indicia to a playlist server; and

(d) in the playlist server, forwarding the received indicia to the user'"'"'s equipment to update a playlist.

2. A method according to claim 1 wherein said forwarding the captured indicia to the playlist server includes transmitting the data over a wireless SMS service.

3. A method according to claim 1 wherein said forwarding the captured indicia to the playlist server includes transmitting the data over a digital wireless call in a voice channel using in-band signaling.

4. A method according to claim 1 wherein said forwarding the captured indicia to the playlist server includes transmitting the data over a wireless packet data service.

5. A method according to claim 1 wherein the wireless telecommunication device comprises a hand-held cell phone.

6. A method according to claim 1 wherein the wireless telecommunication device comprises a personal digital assistant.

7. A method according to claim 1 and further comprising sending data indicative of a current location of the mobile digital radio receiver to the playlist server.

8. A method according to claim 7 and further including acquiring the said location data from a GPS receiver.

9. A method according to claim 8 and further including acquiring the said location data in response to the said user capture input.

10. A radio system for a vehicle comprising:

a digital radio receiver for receiving and playing a current song in the vehicle;

a processor in the radio receiver that decodes metadata that identifies the current song; and

a short-range radio transmitter in the vehicle coupled to the processor in the radio receiver for transmitting the metadata to a second receiver in the vehicle.

11. A radio system for a vehicle according to claim 10 wherein:

the short-range radio transmitter is a blue-tooth type compatible transmitter.

12. A radio system for a vehicle according to claim 10 wherein:

the short-range radio transmitter is part of a blue-tooth type of transceiver.

13. A radio system for a vehicle according to claim 10 wherein:

the short-range radio transmitter is integrated into the digital radio receiver.

14. A radio system for a vehicle according to claim 10 wherein:

the short-range radio transmitter comprises a blue-tooth compatible transceiver integrated into the digital radio receiver.

15. A radio system for a vehicle according to claim 10 including

a user input to the radio receiver to initiate capture and transmission of the said metadata.

16. A mobile digital radio playlist system comprising:

a mobile digital radio receiver for receiving and playing a current song;

a processor in the radio receiver that decodes metadata that identifies the current song;

a remote server system for maintaining a user account, the server system coupled to a data store for buffering said metadata in association with the user account;

means for transmitting the metadata of the current song from the radio receiver to the remote server system for storage in the data store in association with the user account; and

means for downloading the metadata from the remote server system to user equipment for updating a user playlist on the user equipment.

17. A mobile digital radio playlist system according to claim 16 wherein the means for transmitting the metadata of the current song from the digital radio receiver to the remote server comprises a wireless telecommunications transceiver.

18. A mobile digital radio playlist system according to claim 17 wherein the wireless telecommunications transceiver comprises a hand-held cell phone coupled to the digital radio receiver.

19. A mobile digital radio playlist system according to claim 18 wherein the cell phone is coupled to the digital radio receiver by a wireless connection.

20. A mobile digital radio playlist system according to claim 18 wherein the cell phone transmits the metadata of the current song from the digital radio receiver to the remote server via one of in-band signaling, a short message service, and a packet data service.

21. A method of updating a playlist stored on user equipment, the method comprising the steps of:

(a) capturing metadata of a current song in a mobile digital radio receiver in response to a user capture input;

(b) transmitting the captured metadata from the digital radio receiver to a wireless telecommunication device;

(c) in the wireless telecommunication device, forwarding the captured metadata to a playlist server over a wireless SMS service; and

(d) in the playlist server, forwarding the received metadata to the user'"'"'s equipment to update a playlist.

22. A method according to claim 21 and further including:

sending location data indicative of a current location of the mobile digital radio receiver to the playlist server together with the captured metadata.

23. A method according to claim 22 and further including acquiring the said location data from a GPS receiver.

24. A method according to claim 23 wherein the GPS receiver is integrated into the wireless telecommunication device.

25. A method of updating a playlist stored on user equipment, the method comprising the steps of:

(a) capturing metadata of a current song in a mobile digital radio receiver in response to a user capture input;

(b) transmitting the captured metadata from the digital radio receiver to a wireless telecommunication device;

(c) in the wireless telecommunication device, forwarding the captured metadata to a playlist server over a wireless telecom voice channel using in-band signaling; and

(d) in the playlist server, forwarding the received metadata to the user'"'"'s equipment to update a playlist.

26. A method according to claim 25 and further including:

sending location data indicative of a current location of the mobile digital radio receiver to the playlist server together with the captured metadata.

27. A method according to claim 26 and further including acquiring the said location data from a GPS receiver.

28. A method according to claim 27 wherein the GPS receiver is integrated into the wireless telecommunication device.
