ancillary code of the program in a household memory. A reference
code reader reads the ancillary code of the program received in
the reference site, and stores the ancillary code in a second
memory. The ancillary codes in the first memory are compared to
data stored in a code-program name library to create a program
identifying viewing record corresponding to the program. The
auxiliary code retrieved from the second memory is compared to
the data stored in the code-program name library to create a
program identifying broadcast record corresponding to the program
(pages 10 and 11).
As shown in figures 1 and 2, the audience measurement system
includes a household metering apparatus 14 located in a household

receives signals from program signal sources 30. Central office
36, installed at central site 38, collects data from household
metering apparatus 14, reference apparatus 32, and from external
program records sources (page 20). Program signals can be
distributed by coaxial cables, rented video tapes, video disks,
and/or the like. Household metering apparatus 14 also includes
