Abstract

A method for capturing a broadcast is disclosed. The method for capturing a broadcast includes detecting an approximate start time of the broadcast, wherein said detecting includes monitoring for a broadcast trigger, identifying the broadcast and a timed length thereof, such that, based on the timed length and the approximate start time, an approximate end time may be calculated, and recording the broadcast from the trigger to the approximate end time, wherein said recording has captured the broadcast of radio advertising.

Claims

1. A method for capturing a broadcast, said method comprising:

detecting an approximate start time of the broadcast, wherein said detecting includes monitoring for a broadcast trigger.;

identifying the broadcast and a timed length thereof, such that, based on the timed length and the approximate start time, an approximate end time may be calculated; and

recording the broadcast from said trigger to said approximate end time,

wherein said recording has captured the broadcast of radio advertising.

2. The method of claim 1, wherein said broadcast comprises radio advertising.

3. The method of claim 1, wherein said detecting is performed post traffic merge.

4. The method of claim 1, wherein said detecting is performed before traffic merge.

5. The method of claim 1, wherein said detecting is based on a play log.

6. The method of claim 1, wherein said identifying comprises post merge duration information.

7. The method of claim 1, wherein said recording comprises a recorder placed within the broadcast range of the broadcast.

8. The method of claim 1, wherein said recording comprises recording using the internet.

9. The method of claim 1, wherein said recording is performed digitally.

10. The method of claim 1, wherein said recording includes tagging the recording with at least the time recorded and the frequency of the broadcast.

11. The method of claim 1, wherein said identifying comprises performing analysis of factors.

12. The method of claim 11, wherein said factors include at least one of weather, listenership, ratings, previously played advertising, upcoming programming, day of the week and time of day.

13. The method of claim 1, wherein said trigger is a digital marker.

14. The method of claim 1, wherein said trigger is a fingerprint.

15. A method for verifying a broadcast of radio advertising, said method comprising:

analyzing a captured broadcast containing the radio advertising; and

,

comparing said analyzed captured broadcast with the intended ad to broadcast,

wherein said comparing verifies that the captured broadcast is substantially equivalent with the intended ad.

16. The method of claim 15, wherein said analyzing includes determining portion of the captured broadcast containing the radio advertising.

17. The method of claim 15, wherein said analyzing includes isolating the radio advertising.

18. The method of claim 17, wherein said isolating includes clipping recorded buffer time.

19. The method of claim 15, wherein said analyzing includes signal processing.

20. The method of claim 15, wherein said comparing includes peak matching of the captured broadcast with the intended ad.

21. The method of claim 15, wherein said comparing includes a duration comparison of the captured broadcast with the intended ad.

22. The method of claim 15, wherein said analyzing includes verification of conditions during which the captured broadcast was broadcast.

23. A method for verifying the content of broadcast media play, said method comprising:

analyzing a captured broadcast containing the media play; and

,

comparing said analyzed captured broadcast with the intended media play to broadcast,

wherein said comparing verifies that the captured broadcast is substantially equivalent with the intended media play.

24. The method of claim 23, wherein the verifying of broadcast media play is used for Sarbanes Oxley reporting.
