Claim 10:
11. A computing device comprising:
a network interface for: (i) receiving a set of reference fingerprints from a remote device, the set of reference fingerprints corresponding to media presented at a location, and (ii) transmitting audience measurement information to identify the media presented at the location;
memory to store the set of reference fingerprints;
a signature processor to generate a monitored fingerprint of the media presented at the location; and
a signature comparator to: (i) compare the monitored fingerprint to at least some of the set of reference fingerprints, (ii) identify a match between the monitored fingerprint and one or more reference fingerprints of the set of reference fingerprints, the match identifying the media presented at the location, and (iii) determine an anchor point in the identified media based on the one or more reference fingerprints, the anchor point indicative of an amount of time that has passed since the media started;
wherein the audience measurement information to identify the media is transmitted responsive to the match identifying the media, the audience measurement information including data indicative of the amount of time that has passed since the media started.
