Abstract: Method and apparatus for automatically enhancing the foliage display of a color signal includes providing the color signal in multiplexed form having alternating first and second components, the first component being substantially aligned with a flesh tone color space axis, the second component being substantialy aligned with a green tone color space axis. A de-multiplexing unit separates the first and second components to provide a first de-multiplexed component substantially aligned with the flesh tone axis and a second de-multiplexed component substantially aligned with the green tone axis.

Abstract: A video display deflection circuit includes a source of a video signal for displaying picture information contained in the video signal in a screen of a cathode ray tube. The video signal on-provides selectively an on-screen-display information and a non-screen-display information. A source of a first control signal has a first value, when the video signal provides on-screen-display information and a second value, when said video signal provides non- on-screen-display information. A comb filter responsive to the first control signal has selectively a first delay element, when the first control signal is at the first value and a second delay element, when the first control signal is at the second value. The filter selectively establishes, in accordance with the first value, a first frequency response characteristic and, in accordance with the second value, a second frequency response characteristic.

Abstract: A video display deflection circuit includes a source of a video signal for displaying picture information contained in the video signal in a screen of a cathode ray tube. The video signal provides selectively on-screen-display information and non-on-screen-display information. A source of a first control signal has a first value, when the video signal provides on-screen-display information and a second value, when said video signal provides non-on-screen-display information. A waveform generator is responsive to the first control signal for generating a second signal at a frequency that is related to a deflection frequency having a first waveform, when the video signal provides on-screen-display information, and a second waveform, that is different from the first waveform, when the video signal provides non-on-screen-display information.

Abstract: A video display deflection circuit includes a source of a periodic, first signal that varies in accordance with a position of an electron beam on a screen of a cathode ray tube. A limiter is responsive to the first signal for generating a second signal having a limited, piece-wise linearized first portion, when the first signal is outside a range of values. The second signal has a second portion that varies, when the first signal varies within the range of values. A modulator is responsive to the second signal and to a video signal for generating a modulated correction signal coupled to an auxiliary deflection winding to produce, in accordance therewith, scan velocity modulated deflection of the electron beam.
