Abstract

Abstract A method and apparatus for manufacturing a videotape from a video signal so as to inhibit the making of acceptable copies thereof. The video portion of a video signal from a video source is looped through a sync generator to a frame store to provide the video signal with new vertical positioning and blanking. The output video signal from the frame store is sent to a dual vertical sync inserter to insert a second vertical sync onto the video signal. The output video signal from the dual vertical sync inserter is then sent to a video recorder for recording onto a videotape.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 116 words
A method for manufacturing a videotape from a video signal so as to inhibit the making of acceptable copies thereof; said method comprising the steps of: a) looping a video portion of a video signal from a video source through a sync generator means to a frame store means for providing said video portion of said video signal with new vertical positioning and blanking; b) passing an output video signal from said frame store means to a dual vertical sync inserter means for inserting a second vertical sync onto said video signal; and c) then passing an output video signal from said dual vertical sync inserter means to a video recorder for recording onto a videotape.
Claim 2
Independent Claim 116 words
A method for manufacturing a videotape from a video signal so as to inhibit the making of acceptable copies thereof; said method comprising the steps of: a) looping a video portion of a video signal from a video source through a sync generator means to a frame store means for providing said video portion of said video signal with new vertical positioning and blanking; b) passing an output video signal from said frame store means to a dual vertical sync inserter means for inserting a second vertical sync onto said video signal; and c) then passing an output video signal from said dual vertical sync inserter means to a video recorder for recording onto a videotape.
Claim 3
Dependent Claim 43 words
The method of claim 1 in which is included the step of passing a vertical drive signal from said sync generator means to said dual vertical sync inserter means and deriving the pulse for said second vertical sync from said vertical drive signal.
Claim 4
Dependent Claim 35 words
The method of claim 2 in which is included the step of applying an oscillator signal from an oscillator means to said dual vertical sync inserter means for modulating said dual vertical sync inserter means.
Claim 5
Dependent Claim 26 words
The method of claim 3 in which is included the step of sending an external sync signal from said sync generator means to said video recorder.
Claim 6
Independent Claim 131 words
An apparatus for manufacturing a videotape from a video signal so as to inhibit the making of acceptable copies thereof; said apparatus comprising: a) a sync generator means for allowing a video portion of a video signal to be looped therethrough; b) a frame store means for receiving said video portion of said video signal from said sync generator means and for providing said video portion of said video signal with new vertical positioning and blanking; c) a dual vertical sync inserter means for receiving said video portion of said video signal from said frame store means and for inserting a second vertical sync onto said video signal; and d) a video recorder for receiving an output video signal from said dual vertical sync inserter means for recording onto a videotape.
Claim 7
Independent Claim 131 words
An apparatus for manufacturing a videotape from a video signal so as to inhibit the making of acceptable copies thereof; said apparatus comprising: a) a sync generator means for allowing a video portion of a video signal to be looped therethrough; b) a frame store means for receiving said video portion of said video signal from said sync generator means and for providing said video portion of said video signal with new vertical positioning and blanking; c) a dual vertical sync inserter means for receiving said video portion of said video signal from said frame store means and for inserting a second vertical sync onto said video signal; and d) a video recorder for receiving an output video signal from said dual vertical sync inserter means for recording onto a videotape.
Claim 8
Dependent Claim 45 words
The apparatus of claim 5 in which said sync generator means passes a vertical drive signal to said dual vertical sync inserter means; and in which said dual vertical sync inserter means derives the pulse for said second vertical sync from said vertical drive signal.
Claim 9
Dependent Claim 32 words
The apparatus of claim 6 in which is included an oscillator means for applying an oscillator signal to said dual vertical sync inserter means for modulating said dual vertical sync inserter means.
Claim 10
Dependent Claim 20 words
The apparatus of claim 7 in which said sync generator means sends an external sync signal to said video recorder.
