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:

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 over a wireless telecom voice channel using in-band signaling;

automatically establishing a voice call to a predetermined telephone number corresponding to the playlist server in response to the user capture input if a line corresponding to the wireless telecommunication device is available;

modulating the captured metadata for in-band transmission over the wireless telecom voice channel of the established voice call and forwarding said modulated representation of the captured metadata in-band over the wireless telecom voice channel of the established voice call;

if the line is busy, queuing the captured metadata for a later transfer;

in the playlist server, forwarding the received indicia to the user equipment to update a playlist; and

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

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

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

4. The method according to claim 1 and further including acquiring the said location data from a GPS receiver.

5. The method according to claim 4 and further including acquiring the said location data in response to the said user capture input.

6. The method according to claim 1 and further including acquiring the said location data from a space based global navigation satellite system.

7. A mobile digital radio playlist system comprising:

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

a processor in the digital 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 over a wireless telecom voice channel using in-band signaling from the digital radio receiver to the remote server system for storage in the data store in association with the user account;

means for automatically establishing a voice call to a predetermined telephone number corresponding to the remote server system in response to decoding the metadata of the current song if a line corresponding to the transmitting means is available;

means for modulating the captured metadata for in-band transmission over the wireless telecom voice channel of the established voice call and forwarding said modulated representation of the captured metadata in-band over the wireless telecom voice channel of the established voice call;

means for queuing the captured metadata for a later transfer if the line is busy; and

means for adding the metadata of the current song into a user playlist on user equipment

8. The mobile digital radio playlist system according to claim 7 wherein the means for transmitting the metadata of the current song from the digital radio receiver to the remote server system comprises a wireless telecommunications transceiver.

9. The mobile digital radio playlist system according to claim 8 wherein the wireless telecommunications transceiver comprises a hand-held cell phone coupled to the digital radio receiver.

10. The mobile digital radio playlist system according to claim 9 wherein the cell phone is coupled to the digital radio receiver by a wireless connection.

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

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

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

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

automatically establishing a voice call to a predetermined telephone number corresponding to the playlist server in response to the user capture input if a line corresponding to the wireless telecommunication device is available;

modulating the captured metadata for in-band transmission over the wireless telecom voice channel of the established voice call and forwarding said modulated representation of the captured metadata in-band over the wireless telecom voice channel of the established voice call;

if the line is busy, queuing the captured metadata for a later transfer;

in the playlist server, forwarding the received metadata to the user equipment to update the playlist; and

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

12. The method according to claim 11 and further including acquiring the said location data from a GPS receiver.

13. The method according to claim 12 wherein the GPS receiver is integrated into the wireless telecommunication device.
