My little U-matic portable (The front says JVC, the
service manual says
Hitachi...) has SO239 socket ('UHF') for the composite video input and
output. It's a 625 line PAL machine, of course -- I have no idea what the
NTSC version uses....
My UMatic experience is really limited to just Panasonic and Sony units
(dating from mid-late 70's thru my newest Sony is maybe 10 years old now).
But interestingly... I was wrong... I HAVE seen the "UHF" connector for
composite. I had completely forgotten about the old closed circuit video
system I pulled out when I started working at my current job.
They had 3 black and white security cameras that used that connector. I
know they were composite video, because I remember using an RCA adaptor,
and connecting one to a VCR's video line in shortly after pulling them
out of service.
So yeah... I have actually seen that setup, I had just forgotten about
it, as it might have been the only place I have seen that (but also, 90%
of my AV experience is from mid 80's to mid-late 90's, so most of what I
was exposed to is the "current standards" connectors). That's why I
disclaimed that I wasn't saying it didn't exist... just that I hadn't
seen it (I have also learned in A/V, if there is a connector out there,
odds are, someone, at sometime, used it in their setup)
