Detection of media links in broadcast signals
First Claim
Patent Images
1. An apparatus comprising:
- a meter to record a media link embedded in a commercial tuned by a tuner, the media link being activatable to retrieve content different from the tuned commercial from a content provider, the meter to further record at least one of a signature and a program identification code to identify the commercial, and the meter to timestamp at least one of the media link, the signature and the program identification code;
a program identifier to identify the commercial based on at least one of the media link, the signature and the program identification code; and
a computer to verify whether the media link was a correct media link to be broadcast with the identified commercial.

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.

7. A verification system comprising:
-
a meter to create a log of URLs and program identifiers received via a tuner, the log including channel identifiers reflecting channels on which the URLs were received and timestamps reflecting times and dates on which the URLs were detected; a verification computer to process the log against a database to verify at least one of; whether at least one of the URLs was transmitted within an agreed time on an agreed channel;
orwhether the at least one of the URLs was transmitted in association with a predetermined program. - View Dependent Claims (8, 9)

10. A verification system comprising:
-
a meter to create a log of URLs and program signatures received via a tuner, the log including timestamps reflecting times and dates on which the URLs were detected; a program identifier to identify a first program based on at least one of a first URL and a first signature in the log; a verification computer to process the log against a database to verify at least one of; whether the first URL was transmitted within an agreed time on an agreed channel; whether the first program with which the first URL was transmitted with a predetermined program with which the URL was agreed to be transmitted;
orwhether the first URL was broadcast at least an agreed number of times. - View Dependent Claims (11)
