[net.misc] ESPN Cable TV Question

espo@bpa.UUCP (06/16/83)

	Does anyone know what the 4 or 5 audio signals just prior
	to ESPN going to an advertisement means ???  I've noticed
	that this doesn't happen all the time, but probably every
	3rd or 4th programming break.  Maybe something to do with
	the satellite hook-up ??

Much of the audio for television networks is sent through
the phone system.  Notice that it sounds sort of like
a touch-tone.  I believe that it's probably some kind
of "escape sequence" or somesuch; maybe it's a wake up 
for the local franchises (who get the network for users) 
to say that this is a station-break: i.e., commercial time 
set aside that is the right of the local group to solicit.
