Envy Post keeps it legal with Eyeheight

Envy Post Production, one of London's largest independent video facilities, has invested in an Eyeheight legaliseHPPi video legalizer. Installed in its machine room, the legaliseHPPi automatically conforms any HD or SD output from Envy’s router to standard broadcast signal levels.

The company is using the new legaliseHPPi in series with its existing Eyeheight legalEyes to ensure signals are legal in both the RGB and composite domains.

Eyeheight's legalHHPi HD legalizer restricts the Y, U and V components of incoming HD-SDI signals by selectively reducing the saturation of pixels, which would otherwise result in overmodulation of the composite waveform. Composite mode preserves the hue of each pixel
but not the saturation. When the signal is converted to a composite waveform, the Y component is held within the range allowed by the Y high-clip and Y low-clip. The total composite waveform is maintained within the range defined by composite high-clip and composite low-clip.

Eyeheight's legalHHPi hue-processing legalizer is available in half and full rack width configurations, both being fully controllable from the front panel. Power consumption is less than 50W, 100V to 240V AC.

Eyeheight will exhibit at IBC2007 in Amsterdam on stand #2.338.

With higher resolutions and larger HD screens, wide shots using very wide lenses can be a problem because they allow viewers to see that infinity doesn’t quite resolve into perfect sharpness.
