You just keep showing more and more ignrance. All the studio
cameras had RGB outputs. The Vital Industries video switcher and

cameras & monitors only. Master control did every thing else. Just
admit that you are absolutely clueless about what was done, and how
in a NTSC brodcast plant.

So this means any studio vision mixer and switching systems were also
RGB?

Can't you read?

"The Vital Industries video switcher and the Squeeze Zoom had RGB
inputs and outputs." The pair did video mixing, framestore and special
effects.

So this device which did all the normal vision mixer duties only handled
RGB in? Just trying to get clear what you mean.


Sigh. NO. It could handle anything you threw at it. The two Vital
Industries system filled a six foot rack. The Squeeze Zoom was over
$250,000 and the video mixer & effects was around $150,000.


The composite output was hard routed to the 7 GHz STL from
Orlando to the transmitter in Orange City. Any tape delayed programming
was at the transmitter site, on a LaCarte system. The live feed was
monitored by the transmitter operator. and could be used at any time, if
needed.

I realize you've never seen the equipment, but your overall ignorance
is annoying. You're more like Phil with every post.

On the contrary. You seem to think the way you've experienced things to be
the only way they were done. And given it seems to have been on a much
smaller operation than I'm talking about, it's you with your head in the
sand.


I've been trying to explain how it is done in a NTSC plant. You keep
trying to tell me it's wrong, since you've never used the equipment.
All a bigger plant means is more redundant equipment, but you insist on
pulling out a ruler and waving your dick. it was a single station, not
a network station. The only 'network' station was the AFRTS station in
Alaska and it still used mostly film, since some posts had no OTA TV, so
they had channel CATV systems or just ran the films in a small theater.
There were 12 locations in each group. Cases of film arrived in the mail
every few days. After they were run, they were mailed to the next
location, and finally back to AFRTS headquarters in Los Angeles. At one
time AFRTS was the largest network in the world. it was also the last
network to use mostly tube equipment, because a lot of their radio
stations were unmanned most of the time. Our radio station received the
Alaskan Forces Network over the 'White Alice' network. It was the
world's first Over The Horizon Microwave Relay telephone system. There
is a lot of information on line, you should read it.

You damned the station for having no video tape in the '70s. You
have no concept about how the military works. Film was reliable and
cheap. It didn't need much maintenance, or thousands of spare parts.
