It was RCA's strategic decision to place so-called "colorplexers" on the
output of each and every camera, perhaps to increase the total system
cost, or, more likely, to allow unified video switching [ * ] .
The cameras themselves were component-level RGB.
[ * ] Incidentally, the switching/cutting and fading and dissolving
issues with NTSC color are remarkably the same as with film color. Fading
to black, in both systems, is actually a dissolve to a black signal
(NTSC, which implicitly incorporates a color "burst") or to an unexposed,
but developed color negative "slug" (which implicitly incorporates an
orange "mask").
