Rocket is darn close. Signals come from the RF mobile camera(s). Then
to the plane/helicopter/blimp/arial device which returns the signal to
a ground based receiver for the production truck. The truck then
switches all cameras/audio feeds, adds graphics, etc. and sends it to
a satellite truck. The satellite truck sends it to the "bird" and the
bird sends it back down to an earth station. Our earthstation, which
is about 4 miles from our main facility, then sends the signal to our
master control (my home away from home). FWIW our earthstation sends
out all of CBS' national feeds, A&E, History Channel, Discovery People
and in two weeks, the NBA channel. Once the signal feed is in the
master control/playback, we do the commercial insertion, news
"squeezeback" at :15 and :45, and the like, it goes back to the
earthstation, up to the bird (Satcom C4, transponder 11), and back
down to your 1 meter dish, cable system AND DirecTV. DirecTV then
sends the signal back up once more, so that those subscribers can see
it. We have a DirecTV monitor in the playback and it is about two
seconds from the time it leaves the switcher to the time it airs on
DirecTV.
There will be a quiz on this tomorrow, so I need you all to study
hard. :^)
