Most users will use one of the six full amplitude saturated colors, or black or white, for the key color. (See Table xx).

The situation is more complex if you wish to key on a color other than a full amplitude saturated color, or if your host computer outputs non-standard signal levels. You must then understand how chroma key levels are handled by the system.

The chroma key circuitry in the SuperView is designed to operate with a variety of frame buffer output levels. The key color acceptance range you specify may not be centered on the color value you wrote to the host computer frame buffer (see the following discussion).

high-resolution frame buffers generally output video which falls into one of three different voltage ranges depending on the design. These voltage ranges are:

•0.700 Volt p-p (black level of 0 V)

•0.714 Volt p-p (black level of 54 mV)

•1.000 Volt p-p (black level of 0 V)

Probably 98% of computers fall into the first two categories. The voltage levels are sufficiently close that, in most cases, the same key range will work for both. Only the peak-to-peak video amplitude is of concern; the SuperView contains circuitry to cancel any DC offsets. The upper and lower thresholds for the chroma key are determined by eight bit digital-to-analog converters. The converters output a voltage in the range -270 mV to +1250 mV.

Consider a computer frame buffer with a 700 mV output voltage range. We want to key on full amplitude saturated cyan, i.e. no red, full amplitude green and full amplitude blue. To accomplish this, let’s choose ranges such that we are looking for a red value less than 25% of maximum, and green and blue values which are greater than 75% of maximum. These may appear to be relatively large ranges, but they reserve only 1.6% of the available color gamut for the
