Abstract: A people monitoring system comprises a first unit (32) which receives data related to the number of people who are watching a television set, the unit being provided with switches (30) operable by such people to produce such data; and a second unit (33), remote from the first unit, which accepts and stores such data.
Abstract: An arrangement is disclosed which stores data received from a people monitoring unit which produces information relating to the number of people watching a television set and/or from a television channel detection unit of a television monitoring system. The arrangement transmits such data to a remote computer by means of a telephone line (87) of a public telephone network upon interrogation by the computer.

Abstract: A television channel detecting arrangement, for detecting to which channel a television set is tuned, comprises an inductive loop (14) for receiving a signal from a local oscillator (10) of the television set (12); a tuner (16); a detector (18,20) which are such that, when the tuner is tuned to the frequency of the signal from the local oscillator, a voltage is generated at the detector; and a counter (25) which addresses a store (24) which uses stored binary numbers to vary over a range the frequency to which the tuner is tuned.
Abstract: A transmission arrangement comprising a receiver (58) for accepting data from at least one of a people monitoring unit which produces information relating to the number of people watching a television set and a television channel detection unit of a television viewing monitoring system and a transmitter (T1, 53, 50, 52, 54, 56, S51, 60, 62, T2) for transmitting such data as a multibit digital word to a data storage device by way of a mains wiring system.
