Abstract

A customer relationship management (CRM) method using IBOC-radio signals is provided. A message in the radio signal is parsed to obtain a key. The key is compared to a plurality of stored keys. When the received key matches a stored key, a data structure associated with the message is outputted. A device comprising a lookup table with a plurality of stored keys, a tuner unit that receives a CRM in an IBOC signal, and a controller in electrical communication with the lookup table and tuner is provided. The controller comprises (i) instructions for comparing a key in the CRM to one or more stored keys in the plurality of stored keys and (ii) instructions for permitting the display of a display text associated with the received key when there is a match between the received key and a key in the plurality of stored keys.

Claims

1. A method of providing customer relationship management in a radio system, the method comprising:

tuning the radio system to a frequency band containing a locally-broadcast terrestrial radio signal;

receiving said locally-broadcast terrestrial radio signal comprising a main signal component and a side data component wherein said side data component comprises a message;

parsing said message to obtain a key;

comparing said key to a plurality of stored keys in a lookup table; and

when said key matches a stored key in said plurality of stored keys, said message is outputted to an output device, and

when said key does not match any stored key in said plurality of stored keys, said message is not outputted to said output device.

2. The method of claim 1, wherein said locally-broadcast terrestrial radio signal is an IBOC- or an RDS-radio signal and wherein said frequency band is within the FM frequency spectrum.

3. The method of claim 1, wherein said locally broadcast terrestrial radio signal is an IBOC-radio signal and wherein said frequency band is within the AM frequency spectrum.

4. The method of claim 1, wherein said message is a display text, an audio segment, or a video segment.

5. The method of claim 1, wherein said output device is a speaker.

6. The method of claim 1, wherein said output device is a video display capable of displaying alphanumeric characters.

7. The method of claim 1, wherein said output device is a video display capable of displaying video characters.

9. The method of claim 1, wherein said message further comprises a received code, and wherein said method further comprises searching a message lookup list, the lookup list comprising a plurality of stored codes, for a stored code that matches said received code, wherein,

when a stored code is found in said plurality of codes that matches said received code, a data structure associated with said matching stored code is the data structure outputted to said output device.

10. The method of claim 9 wherein said code has a size of 8 bits or 16 bits.

11. The method of claim 1 wherein said key has a size of 32 bits.

12. The method of claim 1, wherein said message is encrypted, and wherein the method further comprises decrypting said message prior to said parsing.

13. The method of claim 1, the method further comprising reading a time slot schedule to identify a permitted time, and wherein said receiving, parsing, and comparing are only performed during said permitted time.

14. The method of claim 13 wherein said permitted time is a specified time interval occurring in a time period.

15. The method of claim 14 wherein said time period is a minute, an hour, a day, a week or a month.

8. (canceled)

16. A device comprising:

a lookup table comprising a plurality of stored keys;

an output device;

a tuner unit for tuning into and receiving a locally-broadcast terrestrial radio signal comprising a main signal component and a side data component wherein said side data component comprises a message;

a decoded digital data controller in electrical communication with (i) said lookup table, (ii) said output device, and (iii) said tuner unit, said decoded digital data controller comprising;

instructions for parsing said message to obtain a key, and instructions for comparing said key to said plurality of stored keys;

wherein

when said key matches a key in said plurality of stored keys, said message is outputted to an output device, and

when said key does not match any key in said plurality of stored keys, said message is not outputted to an output device.

17. The device of claim 16, wherein said locally-broadcast terrestrial radio signal is an IBOC- or a RDS-radio signal and wherein said locally-broadcast terrestrial radio signal is within the FM frequency spectrum.

18. The device of claim 16, wherein said locally broadcast terrestrial radio signal is an IBOC-radio signal and wherein said locally-broadcast terrestrial radio signal is within the AM frequency spectrum.

19. The device of claim 16, wherein said message is a display text, an audio segment, or a video segment.

20. The device of claim 16, wherein said output device is a speaker.

21. The device of claim 16, wherein said output device is a video display capable of displaying alphanumeric characters.

22. The device of claim 16, wherein said output device is a video display capable of displaying video characters.

24. The device of claim 16, the device further comprising:

a message lookup list, the lookup list comprising a plurality of stored codes; and

wherein said message further comprises a received code, and wherein

said decoded digital data controller further comprises instructions for searching said message lookup list for a stored code that matches said received code,

wherein,

when a stored code is found in said plurality of stored codes that matches said received code, a data structure associated with said matching stored code is the data structure outputted to said output device.

25. The device of claim 24 wherein said code has a size of 8 bits or 16 bits.

26. The device of claim 16 wherein said key has a size of 32 bits.

27. The device of claim 16, wherein said message is encrypted, and wherein the decoded digital data controller further comprises instructions for decrypting said message prior to said parsing.

28. The device of claim 16, the device further comprising:

a time slot schedule;

wherein

said decoded digital data controller further comprises instructions for reading said time slot schedule to identify a permitted time, and wherein said instructions for parsing, and said instructions for comparing are only performed during said permitted time.

29. The device of claim 28 wherein said permitted time is a specified time interval occurring in a time period.

30. The device of claim 29 wherein said time period is a minute, an hour, a day, a week or a month.

31. The device of claim 16, the device further comprising a time slot schedule, and wherein said decoded digital data controller further comprises instructions for polling said time slot schedule, wherein said instructions for parsing and said instructions for comparing are not performed during a time not permitted by said time slot schedule.
