Those "secondary" subchannels are High Definition broadcasts.
No,they aren't.
The subchannels are able to be aired because they compress several
standard-def digital channels to transmit in the HD bandwidth.
I have a recollection that the broadcasters had a choice with their
new frequencies: 1) High Def on one channel, or
2) Multiple channels of standard def.
in the space of one channel. And if they chose option 2, the signals
were not in hi-def. Although they would be clearer because they were
digital (no static, no ghosts). Am I wrong?
You are right.
