Abstract
Abstract A cable-ready television set having a controller with first and second sets of leads for scanning a plurality of push-button switches and, in response to actuation of the switches, entering into a tuner memory designations defining which channels may be selected for viewing and which channels may not be selected, is modified by disconnecting the switches and connecting the first and second sets of leads to a first connector accessible from the exterior of the set. A hand-held programming module includes a plurality of programming switches connected to a second connector so that each programming switch is connected between one lead in each of the first and second sets of leads when the connectors are mated. The hand-held module includes a non-volatile memory for storing tier data and a microprocessor responsive to actuation of tier selection switches on the module for applying the tier data to the programming switches. Actuation of the programming switches causes the tuner controller to load the tuner memory with designations indicating which channels may or may not be viewed.

Claim 2
Dependent Claim
209 words
A programming system for limiting access to channels which may be viewed on a television receiver, said television receiver having therein a tuner controller, a tuner memory and first and second sets of leads, the tuner controller producing output signals on said first set of leads for scanning programming switches and having inputs connected to said second set of leads and responsive to scanning signals passing through said switches for accessing said tuner memory, said first and second sets of leads being connected to a first connector accessible from the exterior of said television receiver; a programming module having therein a microprocessor, a non-volatile memory for storing tier data, and a plurality of programming switches, said programming module having thereon a plurality of tier selection switches, said microprocessor being responsive to actuation of one of said tier selection switches for sequentially accessing said non-volatile memory and reading therefrom tier data for selectively actuating said programming switches to transmit channel numbers to said controller; and cable means connected to said programming switches and terminating at a second connector matable with said first connector whereby each of said programming switches is connected between a lead of said first set and a lead of said second set when said connectors are mated.
Claim 3
Dependent Claim
51 words
A programming system as claimed in claim 1 wherein a voltage source is connected to a pin of said first connector and said microprocessor is connected to a lead which terminates at a corresponding pin of said second connector whereby power for operating said microprocessor is derived from said television receiver.
Claim 4
Dependent Claim
41 words
A programming system as claimed in claim 1 wherein said tier data comprises a tier of data corresponding to each tier selection switch, each of said tiers of data defining the channel numbers of channels to which viewer access is permitted.
Claim 5
Dependent Claim
58 words
A programming system as claimed in claim 1 wherein, following actuation of said programming switches to transmit a channel number, the microprocessor actuates one of said switches to transmit a Channel Up signal to said controller, said controller being responsive to a channel number and a Channel Up signal for entering into said tuner memory a "saved" status.
Claim 6
Dependent Claim
37 words
A programming system as claimed in claim 1 wherein said microprocessor, in response to actuation of one of said tier selection switches, energizes said programming switches to alternately transmit Skip and Channel Up signals to said controller.
Claim 7
Dependent Claim
129 words
The combination comprising: a tuner controller; a television receiver including, a tuner memory for storing saved and skipped designations of channels which may be viewed and may not be viewed; a first connector connected to said controller through which channel number signals and Enter signals may be applied to said tuner controller; said controller being responsive to said channel number signals and said Enter signals for accessing said tuner memory to store therein a saved designation for those channels whose channel numbers are applied to said controller; and, a hand-held programming module having a second connector mating with said first connector, said programming module having therein means for applying channel number signals and Enter signals to said tuner controller in response to scan signals generated by said tuner controller.
Claim 8
Dependent Claim
129 words
The combination comprising: a tuner controller; a television receiver including, a tuner memory for storing saved and skipped designations of channels which may be viewed and may not be viewed; a first connector connected to said controller through which channel number signals and Enter signals may be applied to said tuner controller; said controller being responsive to said channel number signals and said Enter signals for accessing said tuner memory to store therein a saved designation for those channels whose channel numbers are applied to said controller; and, a hand-held programming module having a second connector mating with said first connector, said programming module having therein means for applying channel number signals and Enter signals to said tuner controller in response to scan signals generated by said tuner controller.
