Abstract

A detection apparatus includes a tuner tuned to the program and a meter coupled to the tuner and arranged to detect content ancillary information from the program tuned by the tuner. The content ancillary information may be a media link, closed captioning information, or the like. The meter may also be arranged to extract a broadcast signature from the program. A comparator compares the broadcast signature to a reference signature selected from a library of reference signatures based upon the content ancillary information. Broadcast signatures from unknown programs may be clustered at least partially on the basis of the content ancillary information.

Claims (43)

1. A detection apparatus for the detection of a media link embedded in a program comprising:
a tuner tuned to the program; and, a meter coupled to the tuner and arranged to detect the media link embedded in the program tuned by the tuner.
2. The detection apparatus of claim 1 wherein the tuner comprises a scanning tuner.
3. The detection apparatus of claim 2 wherein the scanning tuner tunes to a plurality of channels, and wherein the meter is arranged to detect media links from programs carried in the tuned channels.
4. The detection apparatus of claim 1 further comprising a program identifier, wherein the program identifier is arranged to identify the program directly from the media link.
5. The detection apparatus of claim 1 further comprising a program identifier, wherein the program identifier is arranged to identify the program by accessing a content provider.
6. The detection apparatus of claim 1 further comprising a program identifier, wherein the program identifier is arranged to received a manual identification of the program.
7. The detection apparatus of claim 1 wherein the media link is a URL.
8. The detection apparatus of claim 1 wherein the media link is a code referenced to a URL.
9. A data acquisition system for the acquisition of identifying data from a program comprising:
a tuner tuned to the programs and, a meter coupled to the tuner and arranged to capture first and second program identifying datum identifying the program tuned by the tuner, wherein the first program identifying datum is a media link embedded in the program, and wherein the second program identifying datum is a program identifying datum other than a media link.
10. The data acquisition system of claim 9 wherein the tuner comprises a scanning tuner.
11. The data acquisition system of claim 10 wherein the scanning tuner tunes to a plurality of channels, wherein the meter is arranged to capture media links from programs in the tuned channels, and wherein the meter is arranged to capture second program identifying data identifying programs in the tuned channels.
12. The data acquisition system of claim 9 further comprising a program identifier arranged to identify the program from the first and/or second program identifying data.
13. The data acquisition system of claim 12 wherein the program identifier is arranged to identify the program by comparing the first and/or second program identifying data to corresponding first and/or second reference identifying data.
14. The data acquisition system of claim 9 wherein the second program identifying datum is a signature extracted from the program.
15. The data acquisition system of claim 9 wherein the data acquisition system is arranged to keep the second program identifying datum only if the meter fails to acquire the first program identifying datum.
16. The data acquisition system of claim 9 further comprising a program identifier, wherein the program identifier is arranged to identify the program directly from the media link.
17. The data acquisition system of claim 9 further comprising a program identifier, wherein the program identifier is arranged to identify the program by accessing a content provider.
18. The data acquisition system of claim 9 further comprising a program identifier, wherein the program identifier is arranged to receive a manual identification of the program.

b) detecting content ancillary information from the programs; and, c) comparing one of the broadcast signatures having content ancillary information associated therewith to others of the broadcast signatures having associated therewith substantially the same content ancillary information.
32. The method of claim 31 wherein step c) comprises the following step:
comparing the one broadcast signature to others of the broadcast signatures not having associated therewith any content ancillary information.
33. The method of claim 31 wherein step c) comprises the following step:
comparing the one broadcast signature to others of the broadcast signatures having content ancillary information associated therewith which are different than the content ancillary information associated with the one broadcast signature.
34. The method of claim 31 wherein the one broadcast signature is a first broadcast signature, and wherein step c) comprises the following step:
comparing a second broadcast signature to others of the broadcast signatures not having content ancillary information associated therewith, wherein the second broadcast signature also does not have content ancillary information associated therewith.
35. The method of claim 31 wherein the content ancillary information is a media link.
36. The method of claim 35 wherein the media link is a URL.
37. The method of claim 35 wherein the media link is a code referenced to a URL.
