The six remaining luminance intervals are chrominance modulated in the
following order: Yellow, Cyan, Green, Magenta, Red, and Blue. The luminance level
for yellow is +69 IRE and the chrominance modulation level is +/31 IRE. Luminance
for Cyan is +56 IRE and chrominance modulation is +/- 44 IRE. Luminance for Green
is +48 IRE and chrominance modulation is +/- 41 IRE. Luminance for magenta is +36
IRE and chrominance modulation is +/41 IRE.
Luminance for Red is +28 IRE and
chrominance modulation is +/- 44 IRE.
Luminance for Blue is +15 and chrominance
modulation is +/31 IRE. These colors correspond to saturated colors transmitted at
75% of full amplitude.
b. The remaining one-forth of the active scanning lines in each field are used
for the transmission of special test information.
This information consist of a
subcarrier signal envelope with a phase corresponding to -I, a reference white
pulse with peak amplitude of 100 IRE, a subcarrier signal envelope with a phase
corresponding to +Q, and a reference black interval (fig 2-2).
