Abstract
Abstract A gate actuated on/off control arrangement for a remotelycontrolled television receiver is disclosed for maintaining the receiver in an operative condition includes circuitry for sensing in the presence of a derived synchronization signal functioning as a gating signal in conjunction with a derived vertical blanking signal serving as a control or command signal. The receiver is remotely turned off by programming the remote control channel selector to select a blank of unused channel which provides no synchronization and blanking signals, thereby allowing the receiver to turn off.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
A receiver turn-off system for a television receiver comprising, synchronization signal sensing means for sensing the presence of vertical synchronization signals associated with television broadcast signals and providing a first control signal in response thereto, means for sensing the presence of vertical blanking signals within the receiver and providing a second control signal in response thereto, said first and second control signals being in time coincidence with one another, and switch means coupled with said synchronization signal sensing means, and said means for sensing the presence of vertical blanking signals responsive to time coincidence of said first and second control signals for de-energizing said receiver in the absence of said either of said control signals.
Claim 2
Dependent Claim
115 words
A receiver turn-off system for a television receiver comprising, synchronization signal sensing means for sensing the presence of vertical synchronization signals associated with television broadcast signals and providing a first control signal in response thereto, means for sensing the presence of vertical blanking signals within the receiver and providing a second control signal in response thereto, said first and second control signals being in time coincidence with one another, and switch means coupled with said synchronization signal sensing means, and said means for sensing the presence of vertical blanking signals responsive to time coincidence of said first and second control signals for de-energizing said receiver in the absence of said either of said control signals.
Claim 3
Dependent Claim
28 words
A system as recited in claim 1 further including means for maintaining said receiver operative for a predetermined time period after either of said control signals become absent.
Claim 4
Dependent Claim
58 words
A system as recited in claim 1 wherein said sensing means for sensing synchronization signals includes transistorized detector means, said means for sensing vertical blanking signals includes voltage divider means coupled for receipt of vertical blanking signals, and said switch means includes relay means having contact means connected to the television receiver for interrupting the power supplied thereto.
Claim 5
Independent Claim
134 words
A method of turning off a television receiver, comprising the steps of; programming said receiver to select at least one channel having television signals broadcast thereon and at least another chaNnel having no television signals thereon, electronically detecting television synchronization signals within said receiver and providing a first control signal in response thereto, sensing the presence of vertical blanking pulses within the receiver and providing a second control signal in response thereto, said first and second control signals being in time coincidence and together being indicative of the receipt of a television signal by said receiver, selecting the channel having no television signals thereon, and electronically turning off said receiver in response to the absence of either or both of said control signals occurring upon selection of said channel having no television signals thereon.
Claim 6
Independent Claim
134 words
A method of turning off a television receiver, comprising the steps of; programming said receiver to select at least one channel having television signals broadcast thereon and at least another chaNnel having no television signals thereon, electronically detecting television synchronization signals within said receiver and providing a first control signal in response thereto, sensing the presence of vertical blanking pulses within the receiver and providing a second control signal in response thereto, said first and second control signals being in time coincidence and together being indicative of the receipt of a television signal by said receiver, selecting the channel having no television signals thereon, and electronically turning off said receiver in response to the absence of either or both of said control signals occurring upon selection of said channel having no television signals thereon.
Claim 7
Dependent Claim
22 words
The method recited in claim 4 wherein the step of detecting synchronization signals includes the step of electronically detecting vertical synchronization signals.
