Abstract
An system for determining time offset of an audio signature from a reference signature time stamp may have a server connected to one or more remote devices. The server may have a receiver connected to one of more communication channels configured to receive an audio signature generated by the remote device and transmitted over the communication channel. The system may have a database at or connected to the server that contains one or more reference audio signatures. Each of the reference audio signatures may have a time stamp also stored in the database. A query engine may compare the remote audio signature to one or more reference audio signatures stored in the database. A processor may be provided to compare a reference timestamp to a timestamp associated with said remote audio signature. The system may be used to evaluate viewing habits and particularly delayed viewing and program playback manipulation such as Fast-forward, slow-motion, skip, rewind and program abandonment.
