ABSTRACT:
Methods and apparatus for media source identification and time shifted media consumption measurements are disclosed. A disclosed method identifies a time shift associated with one of a plurality of media sources local to a media delivery device by generating a library of first signature information local to the media delivery device, wherein the library of first signature information includes records, each of which contains a time stamp, a signature value and a source identifier associated with a respective one of the plurality of media sources, generating second signature information based on media presented via the media delivery device, generating a collection of matching signature information based on the first and second signature information, and performing a time shift analysis on the collection of matching signature information to identify the time shift associated with the one of the plurality of media sources local to the media delivery device.
