There are enough folks around the vintagecomputing community, there must be a parallel world of vintage studio gear, eh? Someone's gonna be nostalgic enough for the NTSC/VHS look someday, to pay top dollar for original hardware. Anyway, I noticed something about the parent comment that I missed earlier -- "for timing purposes". Huh, like I guess the concept of genlock probably still exists, and they're probably passing around a test pattern or black frame or something just as a common sync reference signal? (For similar reasons, a lot of telecom gear uses a 1.544Mbps "all ones T1" signal for sync, even if there isn't a real T1 circuit anywhere.)
