"R.C.A." broadcasting gear 1968

By the way, the camera noise balance is not the same as the relative noise of different colors due to RF noise added to the composite signal during transmission/reception. That involves the CRT gamma (which affects the amount of luminance that is actually "carried by" or produced by the chrominance signal in saturated colors), and the R-Y and B-Y scaling factors in the composite signal. The result in NTSC or PAL is that, measured with a scope, the B-Y is noisier than the R-Y, but once the signals are applied to a CRT, saturated reds look noisier than saturated blues.

Thanks for sharing that RCA Broadcast Gear 1968 magazine, there was an excellent article on the experimental 1967 ATV0 colour broadcast of the Pakenham horse races down here in Australia including a rare colour photo of the camera at the races which I have never before! I have a personal interest in the history of experimental colour television in Australia before we officially went full colour in March 1975!
