Abstract: For an S-video signal, providing luminance and chrominance, luminance is amplified and adjusted over selected frequency ranges for shaping the S-video signal response for permitting the S-video signal to be transmitted over exceptionally long transmission lines while providing a quality picture. In separate channels, chrominance and luminance signals are amplified and impedance matched. A luminance band pass filter permits manual adjustments to a lower range of video signal frequencies and thus changes to white level picture information. A positive feedback network permits user adjustments in an upper video signal frequency range having picture super detail information for providing a picture of high resolution and thus pleasing to the user. A clear picture, brighter and sharper, rather than simply a brighter picture is available whether transmitted over a few or few hundred feet from a video source to the monitor.
