Abstract
Abstract A data storage and transmission system is provided for accumulating and transmitting data from a plurality of remote T.V. panelist locations to a central location. Each remote unit includes a microprocessor, a control memory, and a data store memory. The control memory stores control information for the remote unit, which may include dynamic allocation information. The data store memory is event driven and stores data as to television channel selection and times thereof, and can store viewer reaction data and the like. At a preselected time, each remote unit initiates a telephone call to a central location and identifies itself. Upon successful telephone connection between a remote unit and the central location, any data such as viewer habit and/or reaction data and the like contained in the data store memory is transmitted over the telephone line to the central location.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
260 words
In a system for monitoring habits of cooperating television viewers or panelists, including a central location and a plurality of remote units at a plurality of panelist locations, a remote unit for connection to a television broadcast receiver comprising: means for receiving a television broadcast signal; a viewer control means including a channel selector and a channel lock switch actuable between channel lock and unlock positions and coupled to said means for receiving a television broadcast signal, said channel lock switch functioning in said channel lock position to lock the associated television broadcast receiver to the channel currently selected notwithstanding any subsequent changes in the channel selector; a microprocessor; memory means for storing programming information for said microprocessor and for storing data; timing means for generating time of day information; means for coupling said viewer control means through said microprocessor to the television broadcast receiver, said microprocessor functioning to monitor changes in said channel selector and the state of said channel lock switch and to store same, together with time of day information, in said memory means; a modem for connection of the non-dedicated telephone network; said modem being coupled to and under the control of said microprocessor; register means for setting a unique identification signal for each remote unit, each such unique identification signal corresponding to a preselected unique call-in time for each such remote unit; said microprocessor functioning to establish communication through said modem with the central location at the preselected unique call-in time and to transmit the data stored in said memory means to the central location.
Claim 2
Dependent Claim

In a system for monitoring habits of cooperating television viewers or panelists, including a central location and a plurality of remote units at a plurality of panelist locations, a remote unit for connection to a television broadcast receiver comprising: means for receiving a television broadcast signal; a viewer control means including a channel selector and a channel lock switch actuable between channel lock and unlock positions and coupled to said means for receiving a television broadcast signal, said channel lock switch functioning in said channel lock position to lock the associated television broadcast receiver to the channel currently selected notwithstanding any subsequent changes in the channel selector; a microprocessor; memory means for storing programming information for said microprocessor and for storing data; timing means for generating time of day information; means for coupling said viewer control means through said microprocessor to the television broadcast receiver, said microprocessor functioning to monitor changes in said channel selector and the state of said channel lock switch and to store same, together with time of day information, in said memory means; a modem for connection of the non-dedicated telephone network; said modem being coupled to and under the control of said microprocessor; register means for setting a unique identification signal for each remote unit, each such unique identification signal corresponding to a preselected unique call-in time for each such remote unit; said microprocessor functioning to establish communication through said modem with the central location at the preselected unique call-in time and to transmit the data stored in said memory means to the central location.
Claim 3
Dependent Claim
21 words
A remote unit in accordance with Claim 1 wherein said means for receiving a television broadcast signals comprises a cable converter.
Claim 4
Dependent Claim
72 words
A remote unit in accordance with Claim 1 wherein said second memory means includes a channel substitution table and wherein the contents of said channel substitution table are down loaded from the central location to the remote unit during communication at said unique call-in time, said microprocessor controlling channel selection to effect substitution channel selection at preselected times in accordance with said channel substitution table regardless of the manually viewer selected channel.
Claim 5
Dependent Claim
42 words
A remote unit in accordance with Claim 3 wherein said channel substitution table includes preselected time of day information for said substitute channel selection, and wherein said microprocessor effects the substitute channel selection in accordance with the preselected time of day information.
Claim 6
Dependent Claim
58 words
A remote unit in accordance with Claim 3 which includes a control signal detector means coupled to said means for receiving a television broadcast signal for detecting a control signal contained within said television broadcast signal, and wherein substitute channel selection is effected at preselected times corresponding to occurrence of the control signal in the television broadcast signal.
