I'm a member there, but backhauls are a different animal. Here’s the description from Gary Bourgois’ USENET SATELLITE FAQ:
WHAT IS A WILD FEED, AND WHY ARE THESE SHOWS SENT EARLY?
What we term "Wild Feeds" on the internet would actually be more accurately
called "Recurring Feeds". These are TV shows which are indeed sent out well
before they air on your local or network channel. The answer as to why they
exist is quite simple: This is how the programs are distributed, as it is
cheaper and faster and more reliable to use satellite than the old method of
sending the shows on VIDEOTAPE or FILM. There are two main types of wild
feeds:
(1) Feed from Production House to the NETWORK
In this instance, The studio that makes the original show is in
Los Angeles. The program is shot on film or videotape, and is
then edited by a "Production House". When the program is done,
it is then transmitted from L.A. to New York City (Network
headquarters) where it is picked up and recorded by the network
(CBS, ABC, NBC, FOX) that will be later broadcasting the program.
In almost all cases, these shows are fed with NO COMMERCIALS.
Instead there is a 10 second space where the network will later
put the commercials in. Of all the wild feeds, this is the
dish head's favorite.
(2) Feed from Syndicator to Local Station
This type of feed is used for Talk Shows, some Kids Shows,
and a few Comedy/Drama/Adventure shows that are played at
your local station. Again, your local station will record the
show for later broadcast. In this case there are always the
Syndicator commercials, but there are long black spaces where
your local station will run their own commercials. In the old
days of Television (Your FAQ author worked in TV in that era)
the shows were actually sent on film or tape by UPS. Satellite
delivery is faster and cheaper.
IN REFERENCE TO A SATELLITE COMMUNICATIONS SYSTEM, WHAT DOES A BACKHAUL MEAN,
AND WHAT DOES IT PHYSICALLY REPRESENT??
Backhauls are signals sent from a remote location back to a network operating
center. Usually, but not always on KU band, these are special events and
sports. Since the commercials are usually added by the network, the backhaul
has no commercials, and you get to hear the announcers talk and see them play
with the video effects when the signal is not being broadcast to the world
(before, after the event and during commercial breaks).
What is needed at the backhaul site are cameras, microphones, audio and video
mixing and effects equipment, and an uplink transmitter and small dish to
send the signal to the satellite.
At the network operating center, there is a downlink (receive) dish, and
a receiver to pick up the signal, and pipe it into the audio and video chain
of the network so that it can be sent to those unlucky people who don't have
satellite dishes and have to watch these broadcasts on regular TV or Cable
