US Patent:

6947099, Sep 20, 2005

Filed:

Dec 21, 2000

Appl. No.:

09/745223

Inventors:

Mark Francis Rumreich - Indianapolis IN, US
Ronald Thomas Keen - Indianapolis IN, US

Assignee:

Thomson Licensing - Boulogne-Billancourt

International Classification:

H04N005/21
H04N009/68

US Classification:

348647, 348645, 348679, 348624

Abstract:

An ACC system includes a controllable amplifier having an input coupled to receive a chroma input signal and an output for providing an chroma output signal of controllable amplitude. A first feedback path, including a cascade connection of means for providing a signal representative of a measured burst amplitude, means for providing an error signal representative of the difference between a desired burst amplitude and the measured burst amplitude, and an integrator, is coupled between the output of the controllable amplifier and a gain control input of the controllable amplifier. A second feedback path, coupled from an output of the integrator to an input thereof, reduces the gain of the amplifier means in a controlled manner for values of a burst component of the chroma input signal below a predetermined threshold value provided by a control signal source, the reduction being at a predetermined rate controlled by a scaling signal device, thereby providing an output system response characteristic having a precisely controllable knee and slope below a predetermined amplitude of a burst component of the chroma input signal.

Filed:

Aug 7, 2002

Appl. No.:

10/214439

Inventors:

Ronald Thomas Keen - Indianapolis IN, US

Assignee:

Thomson Licensing - Billancourt

International Classification:

H04N005/16
H04N005/18

US Classification:

348695, 348692, 348694

Abstract:

A color video display signal processor comprises a source of a color difference signal and an analog to digital converter for converting the color difference signal to a digital signal. A potential divider is coupled to reference voltages of the analog to digital converter for generating a clamp voltage. A clamp arrangement is coupled to the color difference signal and to the analog to digital converter and receives the clamp reference voltage. In response to a clamp pulse the clamp arrangement couples said clamp voltage to said color difference signal.

Appl. No.:

10/222001

Inventors:

William John Testin - Indianapolis IN, US
Ronald Thomas Keen - Indianapolis IN, US
Mark Alan Nierzwick - Brownsburg IN, US

Assignee:

Thomson Licensing - Billancourt

International Classification:

H04N 3/24

US Classification:

348634, 348569, 348565

Abstract:

A television monitor display comprises a first selectable source of a first video display signal and a second selectable source of a second signal for video display. A video processor receives signals from the first and second selectable sources and controllably combines the second signal with said first video display signal. A sync separator is coupled to receive the combined signal and generate therefrom separated synchronizing signals. A controller is responsive to user selection of the first selectable source and generates a disable signal for controlling the video processor to inhibit combining of the second signal for a predetermined time.

US Patent:

7106385, Sep 12, 2006

Filed:

Dec 16, 1999

Appl. No.:

09/465038

Inventors:

Ronald Thomas Keen - Indianapolis IN, US

Assignee:

Thomson Licensing - Boulogne-Billancourt

International Classification:

H04N 5/21

US Classification:

348607, 348241, 348622

Abstract:

On a line scanned video display, the frequency of an artifact producing signal within the video passband is selected to be an odd harmonic of one half the horizontal line scan frequency so that adjacent scan lines of the artifact are 180 degrees out of phase with each other. Thus, the artifact is rendered largely visually canceled when viewed due to the integrating characteristics of the eye of the viewer, even though the artifact is still there.

Appl. No.:

10/416554

Inventors:

Ronald Thomas Keen - Indianapolis IN, US

Assignee:

Thomson Licensing - Boulogne

International Classification:

H04N 5/16

US Classification:

348695, 348689, 348691, 348696, 348697, 348698

Abstract:

The invention teaches a method, means and apparatus for clamping a back porch interval of a video signal including clamping a sync-tip level of said video signal to a variable reference voltage, comparing a back-porch voltage level of the sync-tip clamped video signal to a predetermined reference voltage, generating an error signal representative of the difference between the back-porch voltage level and the predetermined reference voltage, and adjusting the variable reference voltage in response to the error signal such that the error signal is minimized.

Abstract:

A video apparatus such as a television signal receiver enables a video display that readily indicates the detected degree of a video attribute such as motion and/or other video attribute present in the video display. According to an exemplary embodiment, the video apparatus includes first circuitry operative to receive video data. Second circuitry is operative to enable a video display corresponding to the video data. The video display includes first and second video attributes. The first video attribute varies in proportion to a detected degree of the second video attribute.
