On the financial side, it is trivial.

The opposite, the bits were paid for but unused back then so
financially it was worth using them. In digital tv every bit has a use
and so a cost, hence they are used for more TV channels instead for
parasitic services. You end up competing with TV if you want any
quantity so hard to make viable today.

On the engineering side, _impossible_.

The opposite, completely trivial now. Digital TV is a mux of a number
of bit streams, some with compressed video others with meta data for
epg, alternate sound, interactive apps etc. Adding another stream to
the mux is trivial, you just have to pay for the bandwidth though as
most are stat muxed it's possible to create room at the expense of the
vbr streams where the video encoders reduce the quality of as result
of back pressure from the stat muxer

And sanction means both "approve of" and "order the death of" and academic
means both "very important learning-related" and "doesn't matter".

His assertion, Brandon, had to do with *whether you can still slip it in
without anyone noticing and having to do anything at any other stage of the
transmission chain*, which was Stargate's Unique Selling Proposition.

Yes, we know that its possible to move bits down a digital distribution
channel, Captain Obvious.  :-)
