They are ALL digital ALL the time on ALL channels.  Digital is not
synonymous with SD, HD or even quality. It's just the new method
of broadcasts, and will be the only method with analog broadcasts
stops (2009?). But, it doesn't necessarily mean the quality or 
resolution of your favorite show or channel will be any better.

The SD channel (if offered by the broadcaster) is always digital, but 
only outputs a 480 signal (same resolution as analog broadcasts).  
The HD channel is also always digital, but the resolution of each 
broadcast varies.  And even  while watching a 1080 show, the adverts 
are usually in 480.
