Abstract

A method and system for the transmission of digital data (210) over existing analog radio frequencies (230) is presented, wherein the digital data may include audio data, visual data or audio-visual data for presentation either with analog broadcast data or at a selectable time. The digital data may be transmitted over a plurality of sub-channels that have varying degrees or reliability (250). A “quality-of-service” process manages the transmission of digital data over various sub-channels based on the reliability of the sub-channel, the amount of digital data and the type of digital data to be transmitted. The digital data may further be encrypted and authenticated.

Claims

1. A method of transmitting digital data on at least one RF carrier of an audio broadcast, comprising:

identifying digital data associated with, but different than a set of broadcast data;

determining synchronization data corresponding to a broadcast event within the set of broadcast data;

assembling a data packet including the digital data and the synchronization data; and

transmitting the data packet to a receiver before the broadcast event, such that the broadcast data is presented with the digital data based on the synchronization data to a consumer of the broadcast data.

2. The method of claim 1, wherein the digital data corresponds to multimedia information for display on a receiver.

3. The method of claim 2 wherein the multimedia information may be stored on the receiver for recall by a user at a desired time.

4. The method of claim 1, wherein said transmitting further comprises transmitting the data packet in a digital format on at least one RF carrier of a central analog frequency on which the broadcast data is transmitted.

5. The method of claim 1 further comprising transmitting the broadcast data on a central analog frequency.

6. The method of claim 1 further comprising determining authentication data for allowing a receiver to authenticate the data packet.

7. The method of claim 6 wherein assembling further comprises including the authentication data in the data packet for allowing the receiver to authenticate the source of the data packet.

8. The method of claim 6 wherein said authentication data includes at least one of a time stamp and nonce information.

9. The method of claim 1 wherein assembling comprises encrypting the data packet with a public key.

10. The method of claim 1 further comprising determining a file size of the data packet.

11. The method of claim 10 wherein transmitting further comprises selecting at least one RF carrier of a central analog frequency based on the file size.

12. The method of claim 11 wherein transmitting further comprises transmitting the data packet on the selected RF carrier.

13. The method of claim 1 wherein said synchronization data comprise san indicating that the data may be stored by the receiver for recall by a user at a desired time.

14. The method of claim 4 wherein the central analog frequency corresponds to a single frequency on one of an amplitude modulated band and a frequency modulated band.

15. The method of claim 1 wherein said data packet comprises data in an extensible mark-up language format.

16. The method of claim 1, wherein the broadcast data is analog data.

17. The method of claim 1 wherein the broadcast data is digital data.

18-19. -19. (canceled)

20. A computer comprising:

a user interface; and

a control system operatively coupled to the user interface and adapted to;

identify a set of broadcast data that will be sent to a user through an RF channel as part of a one-way audio broadcast;

identify digital data associated with, but different than_the set of broadcast data;

determine synchronization data corresponding to a broadcast event within the set of broadcast data;

assemble a data packet comprising;

the digital data; and

the synchronization data; and

transmit the data packet to a receiver before the broadcast event using an in-band, on-channel format, such that the broadcast data is presented with the digital data based on the synchronization data to a consumer of the broadcast data.
