Circuit arrangement for the transmission and presentation of an analog signal with a video signal

Claim 2

A circuit for the transmission and presentation of an analog signal with a video signal on the video picture screen of a television picture tube, comprising a bar impulse transmitter synchronized by synchronizing impulses from said video signal, said bar impulse transmitter generating bar impulses for producing at least one bar of constant brightness on said video picture screen; a mixer stage for receiving said bar impulses from said bar impulse transmitter, said bar impulses being superimposed on said video signal in said mixer stage; modulating circuit means being connected intermediate said bar impulse transmitter and said mixer stage for receiving said analog signal and modulating said bar impulses dependent thereon whereby the length of the bar on said picture screen corresponds to said analog signal; al least one integrator for integrating the bar impulse superimposed on said video signal for each video picture.

Claim 3

A circuit arrangement as claimed in claim 1, comprising a storage being connected to the output of said integrator; and control means for transmitting the contents of said integrator into said storage and extinguishing said integrator upon the reproduction of a video picture.

Claim 4

A circuit arrangement as claimed in claim 1, comprising an integrator for respectively each said bar.

Claim 5

A circuit arrangement for the transmission and presentation of an analog signal with a video signal on the video picture screen of a television picture tube, comprising a bar impulse transmitter syncnronized by synchronizing impulses from said video signal, said bar impulse transmitter generating bar impulses for producing at least one bar of constant brightness on said video picture screen; a mixer stage for receiving said bar impulses from said bar impulse transmitter, said bar impulses being superimposed on said video signal in said mixer stage; modulating circuit means being connected intermediate said bar impulse transmitter and said mixer stage for receiving said analog signal and modulating said bar impulses dependent thereon whereby the length of the bar on said picture screen corresponds to said analog signal; means for producing a plurality of horizontal synchronizing impulses, said bar impulse generator producing a bar impulse after each said horizontal synchronizing impulse after a time period equal for all picture lines which is smaller than the time between two of said horizontal synchronizing impulses, said bar impulse being smaller in comparison with the time interval between two successive of said horizontal synchronizing impulses, said modulating circuit means superimposing a plurality of said bar impulses on said video signal corresponding to the analog signal to be reproduced for each video picture; a timer adapted for synchronizing impulses, said timer emitting a time pulse after each horizontal impulse coinciding with the subsequent bar impulses; a threshold stage receiving said video signal with the superimposed bar impulses for separation of said video signal; an AND-gate having an input connected with the outputs of said timer and threshold stage; and an integrator for integrating the output signal of said AND-gate.

Claim 6

A circuit arrangement for the transmission and presentation of an analog signal with a video signal on the video picture screen of a television picture tube, comprising a bar impulse transmitter syncnronized by synchronizing impulses from said video signal, said bar impulse transmitter generating bar impulses for producing at least one bar of constant brightness on said video picture screen; a mixer stage for receiving said bar impulses from said bar impulse transmitter, said bar impulses being superimposed on said video signal in said mixer stage; modulating circuit means being connected intermediate said bar impulse transmitter and said mixer stage for receiving said analog signal and modulating said bar impulses dependent thereon whereby the length of the bar on said picture screen corresponds to said analog signal; means for producing a plurality of horizontal synchronizing impulses, said bar impulse generator producing a bar impulse after each said horizontal synchronizing impulse after a time period equal for all picture lines which is smaller than the time between two of said horizontal synchronizing impulses, said bar impulse being smaller in comparison with the time interval between two successive of said horizontal synchronizing impulses, said modulating circuit means superimposing a plurality of said bar impulses on said video signal corresponding to the analog signal to be reproduced for each video picture; a timer adapted for synchronizing impulses, said timer emitting a time pulse after each horizontal impulse coinciding with the subsequent bar impulses; a threshold stage receiving said video signal with the superimposed bar impulses for separation of said video signal; an AND-gate having an input connected with the outputs of said timer and threshold stage; and an integrator for integrating the output signal of said AND-gate.

Claim 7

A circuit arrangement as claimed in claim 4, said timer including an output for respectively each said bar at which the timer generates time impulses coinciding with associated bar impulses; a plurality of said AND-gates; each timer output being connected to a first input of respectively one of said AND-gates, the output signal of said threshold stage being transmitted to second inputs of all of said AND-gates; a plurality of said integrators, the output signal of respectively each of said AND-gates being transmitted to respectively each of said integrators.
