Abstract

Methods and apparatuses for processing transmissions and creating an album of audio content are described. In one arrangement, a combined signal including a digital data component and an analog component is transmitted and received by a terminal. The combined signal is separated into the digital data component and the analog component. The analog component is digitized and then cut based upon the digital data component. Metadata from the digital data component is associated with the digitized analog component to create an album of audio content. The album may be stored or sent to an audio player for output. The digital data component may include cutting information and information data. The analog component may be an analog frequency modulation signal and the digital component may be a subcarrier signal in accordance with the DARC standard.

Claims

1. A method comprising:

receiving a combined signal including a digital data component and an analog component;

separating the combined signal into the digital data component and the analog component;

digitizing the analog component;

determining a starting point and ending point of one or more audio entities in the digitized analog component based upon information in the digital data component; and

associating the digitized analog component with data from the digital data component to create an album of audio content comprising the one or more audio entities.

2. The method of claim 1, further comprising storing the album of audio content in a storage medium.

3. The method of claim 1, further comprising sending the album of audio content to an audio player.

4. The method of claim 1, wherein the digital data component includes cutting information and metadata.

5. The method of claim 4, wherein the cutting information includes information about the starting point and ending point of audio content within the digitized analog component.

6. The method of claim 1, wherein the analog component is an analog frequency modulation signal.

7. The method of claim 1, wherein the digital data component is a subcarrier signal in accordance with the DARC standard.

8. The method of claim 1, wherein the digital data component is a subcarrier signal in accordance with the RBDS standard.

9. The method of claim 1, wherein the digital data component comprises metadata corresponding to one or more of an artist or song title of an audio entity in the digitized audio component.

10. The method of claim 1, wherein the digital data component comprises an image corresponding to an audio entity in the digitized audio component.

11. An apparatus, comprising:

a receiver configured to receive a combined analog signal and subcarrier signal;

a processor configured to control the operation of the apparatus, the processor configured to process the received subcarrier signal and analog signal by software programmed to generate an album of audio content;

an encoder configured to digitize the analog signal;

a cutting engine configured to determine a staffing point and ending point of one or more audio entities in the digitized analog signal based upon cutting information within the subcarrier signal;

a digital player configured to output the album of audio content comprising the one or more audio entities;

a storage medium configured to store the album of audio content;

a display configured to show information relating to the album; and

an interface configured to allow a user to interface with the apparatus.

12. The apparatus of claim 11, wherein the subcarrier signal is a digital data signal in accordance with the DARC standard.

13. The apparatus of claim 11, wherein the subcarrier signal is a digital data signal in accordance with the RBDS standard.

14. The apparatus of claim 11, wherein the album of audio content is a listing of audio entities and associated information about the audio entities.

15. The apparatus of claim 11, wherein the interface is configured to allow the user to modify the album of audio content.

16. The apparatus of claim 15, wherein the modification of the album of audio content comprises at least one of:

sorting, deleting an audio entity in the album, and changing the information relating to an audio entity in the album.

17. The apparatus of claim 11, wherein the analog signal is a frequency modulated analog signal.

18. The apparatus of claim 11, further comprising a splitter configured to separate the analog signal from the subcarrier signal.

19. The apparatus of claim 11, wherein the cutting information includes information about the staffing point and ending point of audio content within the digitized analog signal.

20. The apparatus of claim 19, wherein the album is a listing of the cut digitized analog signal with associated information from the subcarrier signal.

21. The apparatus of claim 11, wherein the apparatus comprises a cellular phone.

22. The apparatus of claim 11, wherein the subcarrier signal comprises metadata corresponding to one or more of an artist or song title of an audio entity in the digitized audio signal.

23. The apparatus of claim 11, wherein the subcarrier signal comprises an image corresponding to an audio entity in the digitized audio signal.

24. A computer-readable medium having computer-executable instructions that, when executed, perform:

receiving a combined signal including a digital data component and an analog component;

separating the combined signal into the digital data component and the analog component;

digitizing the analog component;

determining a starting point and ending point of one or more audio entities in the digitized analog component based upon information in the digital data component; and

associating the digitized analog component with data from the digital data component to create an album of audio content comprising the one or more audio entities.

25. The computer-readable medium of claim 24, the instructions when executed further perform storing the album of audio content in a storage medium.

26. The computer-readable medium of claim 24, wherein the digital component is a subcarrier signal in accordance with the DARC standard.

27. The computer-readable medium of claim 24, wherein the digital component is a subcarrier signal in accordance with the RBDS standard.

28. A method comprising:

receiving an analog audio stream;

receiving digital data comprising information identifying a starting point and ending point of one or more audio entities in the analog audio stream;

generating a combined signal including a digital data component corresponding to the received digital data and an analog component corresponding to the analog audio stream, wherein the information identifying the starting point and ending point of the one or more audio entities in the analog audio stream is included within the digital data component, and wherein the digital data component further comprises metadata corresponding to song information of an audio entity in the analog audio stream, and wherein the combined signal is transmitted in accordance with one of the RBDS standard and the DARC standard; and

transmitting the combined signal.

29. An apparatus, comprising:

a processor configured to control at least some operations of the apparatus;

a signal insertion engine configured to;

receive an analog audio stream;

receive digital data comprising information identifying a starting point and ending point of one or more audio entities in the analog audio stream;
