Abstract

A dual-mode receiver that functions both as a digital audio broadcast receiver and a solid-state digital audio content player is described. In a “radio” mode, the receiver is able to: receive a digital audio bitstream, decode the received bitstream, store or render the decoded bitstream either based on an input from a user or a pre-programmed instruction from a user. In a “play” mode, the receiver is able to access the stored digital audio content, or extract stored digital audio content from a compact media device (e.g., compact flash memory) that is interfaced with the receiver.

Claims

1. A digital audio broadcast receiver capable of receiving digital audio broadcast content, said receiver comprising:

a. a perceptual audio decoder decoding said received digital audio broadcast content;

b. an interface receiving a compact media device with stored digital audio content, said receiver extracting said stored digital audio content;

c. one or more storage units capable of storing digital audio content comprising said decoded digital audio broadcast content and said extracted stored digital audio content, and

d. a playlist creator operatively linked to said storage units creating a digital audio content playlist based upon said stored digital audio content.

2. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said receiver further comprises a man machine interface (MMI) for inputting instructions for identifying which of said stored audio content is to form said digital content playlist.

3. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said compact media device is a memory stick.

4. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said memory stick is customizable with a user-defined playlist that is purchasable over a kiosk.

5. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said receiver is capable of receiving broadcast data over an in-band on-channel (IBOC) network.

6. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said compact media device is pre-programmed with a playlist.

7. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, using said pre-programming is done via personal music organizer software.

8. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said receiver further comprises a MMI for inputting instructions for identifying one or more broadcast programs of interest, and said receiver intercepting and recording said programs of interest in said storage units.

9. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said digital audio content stored in said storage units is modified by inserting formatting information at the beginning of each bitstream.

10. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said formatting information comprises one or a combination of the following:

beginning of track, name of artist, name of the album, or track length.

11. A digital audio broadcast receiver capable of receiving digital audio broadcast content, as per claim 1, wherein said digital audio content stored in said storage units is modified by inserting receiver identifying information at the beginning of each bitstream.

15. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 11, wherein said one or more instructions from an interface help generate a playlist comprising said extracted digital content.

16. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 11, wherein said broadcast content is received over an in-band on-channel (IBOC) network.

17. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 11, wherein said interface is used to input and identify one or more broadcast programs of interest, and said receiver intercepting and storing said programs of interest in said one or more storage units.

18. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 11, wherein said digital audio content stored in said storage units is modified by inserting formatting information at the beginning of each bitstream.

19. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 16, wherein said formatting information comprises any of the following;

beginning of track, name of artist, name of the album, or track length.

20. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 11, wherein said digital audio content stored in said storage units is modified by inserting receiver identifying information at the beginning of each bitstream.

21. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 11, wherein said interface is any of the following;

aural, graphical, or a combination of aural and graphical interfaces.

12. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, said receiver receiving, storing, and playing digital audio content, and

when switched to said radio mode, said method comprising the steps of;

(a) receiving a digital audio broadcast content;

(b) decoding said digital audio broadcast content, and

(c) storing and rendering said decoded digital audio content based upon one or more instructions from an interface, and

when switched to a play mode, said method comprising the steps of;

(a) extracting digital audio content from one or more storage units and a compact media device based upon one or more instructions from an interface;

(b) decoding said extracted digital audio content, and

(c) rendering said decoded digital audio content.

13. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 12, wherein said compact media device is a memory stick that is customizable with a user-defined playlist.

14. A method for switching between a “

radio” and

“

play”

mode in a digital audio broadcast receiver, as per claim 12, wherein said play-list is purchasable over a kiosk.

22. A dual mode digital broadcast receiver having a play mode and a record mode, said receiver comprising:

a. a storage media interface for extracting storage content from a compact media device;

b. a PAC decoder for decoding digital broadcast content and said extracted storage content;

c. one or more storage units for storing said decoded content;

d. a recording unit, when in record mode, triggering storage of said decoded digital broadcast content in said one or more storage units;

e. a reproducing unit, when in play mode, rendering either said decoded digital broadcast content in said storage units or said extracted storage content;

f. a user interface unit for receiving user commands, said user commands controlling the operation of said recording unit and said reproducing unit.
