METHODS AND APPARATUS FOR MEDIA SOURCE IDENTIFICATION AND TIME SHIFTED MEDIA CONSUMPTION MEASUREMENTS
First Claim
1. A method of identifying a media source, comprising:
- generating first signature information based on media presented via a media delivery device;
comparing the first signature information to second signature information, wherein the second signature information is derived from a library of signature information local to the media delivery device;
generating a collection of matching signature information based on the comparison of the first and second signature information;
identifying a source of the media presented via the media delivery device based on the collection of matching signature information; and
performing a time shift analysis on the collection of matching signature information by identifying records in the collection of matching signature information having substantially identical signature values and substantially different time stamp values.

Abstract
Methods and apparatus for media source identification and time shifted media consumption measurements are disclosed. A disclosed method identifies a media source by generating first signature information based on media presented via a media delivery device and comparing the first signature information to second signature information. The second signature information is derived from a library of signature information local to the media delivery device. The disclosed method generates a collection of matching signature information based on the comparison of the first and second signature information, and identifies a source of the media presented via the media delivery device based on the collection of matching signature information.
