Abstract:
1. A method comprising: receiving a plurality of hashes of audio content over a data network from a plurality of client devices; identifying a number of client devices from the plurality of client devices exposed to a particular television broadcast based upon a similarity of a first group of concurrent hashes from the number of client devices; detecting a deviation in a second group of concurrent hashes among the number of client devices; based upon the deviation, inferring a commercial break in which a first group of the number of client devices has changed channel and a second group of the number of client devices have stayed on a commercial break in the particular television broadcast; and analyzing averaged data for a third group of concurrent hashes from the number of client devices to determine whether a commercial being played to one or more of the number of client devices is a local commercial or a network-wide commercial.
