Abstract
Abstract An advertising editing system for a video apparatus including a relay for controlling the operation of the video apparatus and a detector for sampling the voltage of the video signal and a comparator for comparing the sampled voltage amplitude with a reference voltage to provide an output voltage signal upon absence of picture information in the video signal for a period of time corresponding to at least one frame to activate the relay and condition the video apparatus during the period of the commercial message.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
An editing system for video apparatus comprising, in combination, switching means for controlling the operation of said video apparatus, means for detecting the voltage level of the video signal in said video apparatus, means connected to a source of power for providing a reference voltage, means for coupling said detecting means to a source of the video signal in said video apparatus, means coupled to said detecting means and responsive to said reference voltage for comparing said detected voltage level with said reference voltage to provide an output voltage signal when the voltage level of said video signal is diminished due to absence of picture information in said video signal for at least a period equal to one frame, and voltage responsive means coupled to said comparing means and responsive to said output voltage signal for activating said switching means for a predetermined period thereby controlling the operation of said video apparatus.
Claim 2
Dependent Claim
152 words
An editing system for video apparatus comprising, in combination, switching means for controlling the operation of said video apparatus, means for detecting the voltage level of the video signal in said video apparatus, means connected to a source of power for providing a reference voltage, means for coupling said detecting means to a source of the video signal in said video apparatus, means coupled to said detecting means and responsive to said reference voltage for comparing said detected voltage level with said reference voltage to provide an output voltage signal when the voltage level of said video signal is diminished due to absence of picture information in said video signal for at least a period equal to one frame, and voltage responsive means coupled to said comparing means and responsive to said output voltage signal for activating said switching means for a predetermined period thereby controlling the operation of said video apparatus.
Claim 3
Dependent Claim
26 words
An editing system in accordance with claim 1 wherein said means for coupling said detecting means to said video signal source includes video signal amplifying means.
Claim 4
Dependent Claim
42 words
An editing system in accordance with claim 1 wherein said video apparatus comprises a video tape recorder having a pause control and including means for connecting said switching means to said pause control to interrupt the operation of said video tape recorder.
Claim 5
Dependent Claim
38 words
An advertising editing system in accordance with claim 1 wherein said video apparatus comprises a television set having an audio output and including means for coupling said switching means to said audio output for discontinuing said audio output.
Claim 6
Dependent Claim
47 words
An editing system in accordance with claim 4 wherein said detecting means include a RC filter including a capacitor, said capacitor being charged to the level of the voltage detected by said detecting means to control the output of said voltage output signal from said comparing means.
Claim 7
Dependent Claim
35 words
An editing system in accordance with claim 5 including means for adjusting the level of the reference voltage in said comparing means to select the output voltage at which said voltage responsive means will respond.
Claim 8
Dependent Claim

An editing system in accordance with claim 6 wherein said voltage responsive means include a pair of control gates, means for connecting the input of one of said control gates to said comparator means, means for connecting the output of said one control gate to the input of the other of said control gates, and means for connecting the output of said other control gate to said switching means.
Claim 9
Dependent Claim
16 words
An editing system in accordance with claim 7 wherein said control gates comprises Schmitt trigger gates.
Claim 10
Dependent Claim
53 words
An editing system in accordance with claim 7 wherein said means for connecting the output of said one control gate to the input of said other control gate include a diode and wherein said timing means are connected between said connecting means for said control gates and said associated source of DC power.
Claim 11
Dependent Claim
34 words
An advertising editing system in accordance with claim 9 wherein said timing means comprises a resistor and a capacitor connected in parallel between said control gates connecting means and said source of DC power.
