Evo Eye Height Legalisers
The legalEyesSDi, legalEyesHDi and legalEyesMDi will correct the levels of a standard and high definition signal respectively, reducing the risk of transmission tapes being rejected by broadcasters. The automatically corrects the levels of an SDI/HD-SDI signal by auto sensing the input standard, also reducing the risk of rejection. All the units incorporate a proc-amp for back lift, luma-gain & chroma adjustments and will provide adjustable “soft-clipping” of the signal in the RGB domain, independant luminance clipping and proprietary “clobbering” ring suppresion.
The legalEyesMDi will restrict the Y, U & V components such that when the signal is converted to a composite waveform the Y component stays within the range allowed by the Y High Clip and Y Low Clip, and the total composite waveform stays within the range defined by Comp High Clip and Comp Low Clip. The legaliser works by selectively reducing the saturation of pixels which would otherwise result in over modulation of the composite waveform. Composite mode preserves the hue of each pixel but not the saturation.
