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: 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.

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.

Abstract: Video signal processing apparatus includes a picture enhancement processor for processing a video signal to produce an enhanced video signal. The video signal includes a signal component representing video image data and another signal component representing non-image data such as vertical sync and a binary information component. The binary information component represents binary information that may occur, for example, during vertical blanking such as closed caption data, content advisory information (V-chip), or extended data services information. A control unit modifies the enhancement performed by the picture enhancement processor during intervals of the video signal that include non-image information. Modifying enhancement processing (e.g., reducing or disabling) during intervals that include the non-image information reduces degradation of the non-image information caused by the enhancement processing.

Abstract: A television system utilizes a common signal processing unit (e.g., a common chrominance demodulator) for processing a combined video signal suitable for coupling to a display device for producing an image having a portion attributable to a main video signal and a portion attributable to an auxiliary video signal. If the common signal processing unit relies upon the color information (e.g., color burst) contained in the main video signal, and the main signal is either non-existent or lacking such color information, then a substitute color information signal will be generated so that the combined video signal may be processed to roduce a color auxiliary image, and a monochrome (or non-existent) main image.
