Is there such a thing as a TV broadcasting service on SW?
One that is not SSTV (Slow Scan TV) -- but some modern digital equivalent
based on H.323 or MPEG...

I don't know of any.

High-speed digital modes tend to have severe problems with the multipath
propagation common on shortwave. You can engineer modulation modes
that'll work on SW, but H.323 isn't one of them.
