As USENIX director I sponsored and sheparded this project, called
"Stargate".
We at least got bits into the blanking interval at WTBS in Altanta.

So... would this have been feasible today? given the bandwidth required 
to send a full feed these days, i suspect likely not, eh? (even if you 
were able to do it on all 500+ channels in parallel)

I can't tell you whether it would be feasible from a *quantity* 
standpoint unless you specify what your group list is -- big 7 text?  
Probably.

Problem is, it depended (as he noted) on a peculiarity of the network TV 
environment at the time: it wasn't part of the signal, but of the 
*transport* which -- at the time -- was carried around along with the 
signal, so you could piggyback stuff there, and get it right to people's 
TVs.  MPEG2 and 4 don't carry the vertical interval, so any ride you can 
get isn't free -- rather similar to our Multicast discussion last week.

Back in the really bad old days, I'm told that the most stable frequency 
source the average civilian could get was the 3.58MHz oscillator in a 
color TV set -- but *only* when you were watching *network* programs, at 
which time that oscillator was effectively phase-locked to a $50k+ black 
burst generator at network master control.

Frame synchronizers shot that plan out of the water.

Never been sure if that's apocryphal or not.
