Line/Fields
The Line/Fields mode of operation displayed is a read-only field deter-
mined by the reference in signal provided to the system.
Matte Limiting
Matte Limiting determines how the matte generators produce colors.
Limits can be imposed to prevent downstream signal problems.
Decodable – This limiter mode produces colors that decode to valid RGB
components. Not all valid RGB colors can be transmitted in NTSC, how-
ever. Saturated colors near yellow and cyan over modulate an NTSC trans-
mitter.
Transmittable – This limiter mode prevents over modulating an NTSC trans-
mitter, but can produce colors which can not be decoded into RGB. For
example, a 0% luminance blue produces negative green and red compo-
nents.
