Fair enough, you have explained low and high band to a point. I thought VTR’s had to be engineered for a given color spec. ie, Pal, SECAM, well these are formats, I understand, bad example. I think you know what I mean, but you’r saying those early modded Quads recorded full 1953 NTSC color?

That being the case and not an engineer, was it a case that early television shows were broadcast with the full 1953 NTSC color signal but the televisions from 1955 and after couldn’t reproduce the complete signal? And SMPTE-C came in about 1968 and shows were being monitored on Conrac monitors with SMPTE-C color space? I’m not understanding.

What was meant by Ed’s comments about “RCA LABS color and RCA Broadcast Color” ?
