Thus, Thomas does not disclose how to determine whether the program was broadcast or played from a tape. It is further argued,(id.) that because the devices from which signatures are extracted and compared are at different sites, these devices are not local to one another. We find that Thomas is directed to an audience measurement system which identifies the programs or stations of televisions or radios that are watched or listened to by an audience (page 1). In the summary of the invention, Thomas states (page 9) that the invention collects data representative of selected programs rather than of tuned stations, including which programs were selected for viewing, which households viewed the program, and what time the program was viewed. A central office automatically determines a program name for each monitored, encoded program. The system identifies a program which is broadcast from a signal source and to which a household is tuned. A reference receiver receives the broadcast at a reference site. A program signature extractor is coupled to the reference receiver to extract and store a reference from the program. The reference signature is compared to the program signature to create a program identifying viewing record corresponding to the program. A household code reader reads an ancillary code of the program and stores thePage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
