An audience measurement system collects data representative of tuned programs rather than of tuned channels, and includes (i) a household metering apparatus which records ancillary codes or extracts program signatures from the programs if no ancillary codes are found therein, (ii) a reference apparatus which monitors broadcast programs to be monitored, which extracts reference signatures therefrom, which records whatever ancillary codes may be associated with these broadcast programs and, if no ancillary codes are present, which compresses and stores a digital replica representative of the broadcast programs to be monitored, (iii) a data collection apparatus which compares the household and reference data to determine (a) which of the broadcast programs to be monitored were selected for viewing and/or listening, (b) which of the metered households selected the broadcast programs to be monitored for viewing and/or listening, and (c) at which times the broadcast programs to be monitored were selected for viewing and/or listening.

An audience measurement system for identifying a program which is broadcast from a signal source and to which a household receiver in a household is tuned, the audience measurement system comprising: reference receiving means for receiving a broadcast of the program at a reference site; program signature extracting means operably coupled to the household receiver for extracting a program signature from the program; reference signature extracting means coupled to the reference receiving means for extracting a reference signature from the program; signature comparing means for comparing the program signature to the reference signature to create a first program-identifying tuning record corresponding to the program; household code reading means operably coupled to the household receiver for reading an ancillary code of the program received in the household; reference code reading means coupled to the reference receiving means for reading the ancillary code of the program received in the reference site; and, code comparing means for comparing the ancillary code received in the household to data stored in a code-program name library to thereby create a second program-identifying tuning record corresponding to the program, and for comparing the ancillary code received in the reference site to the data stored in the code-program name library to thereby create a program-identifying broadcast record corresponding to the program.
